Full Spectrum LED lights produce very bright, white light. The technology is new, exciting and promising. The light may appear to be “normal white” but often contains high energy in the blue spectrum, and some manufacturers are experimenting with UV and infrared. Color balance is subtle, but protection is extremely important. Hence the debut of the Agent 939 LEDfx. Designed to protect you from the high energy spectrums, UV, and infrared all in style and comfort.
Method Seven delivers the LEDFx, a scientific formulation for comfort, visual acuity, safety and performance. The world’s first organic lens to block significant infrared heat energy, which keeps your eyes cool and moist. This is a polycarbonate lightweight lens. The LEDfx lens was designed and developed by Method Seven with over two years of research in collaboration with engineers, optical physicists, ophthalmologists and manufacturing at Carl Zeiss Vision. The lens is perfect for Full Spectrum LED and is also great for urban life outside the grow.
The Agent 939 frame wraps with a curved base 8 lens for full protection along with big and bold temple side for side light protection. Bomber hinges and recessed rubber nose pads make the Agent 939 a comfortable and durable tool. The Agent 939 frame is comfortable and flexible as it's made with TR90! TR90 was produced through Swiss technology as a thermoplastic material that is incredibly durable, flexible, and lightweight. Eyewear made with TR90 have a flexible quality that allows them to bend under pressure and contour your face comfortably.
The Agent 939 LEDFx filters and blocks light so effectively it doesn’t need to be super dark, so your eyes can work naturally even in very bright conditions providing the best experience for your eyes, your plants and your lifestyle.
Method Seven makes optics for gardeners
We've been working with grow lights for over 20 years. We've tolerated the discomfort. Some of us experience night-blindness, see spots get headaches and we know a few who have gone through retina replacement surgery. Not fun.
We've solved all these problems. We can all go back into the grow and start enjoying our plants, safely and comfortably. We've got you covered for any type of lighting. Try them or ask anyone who has. You've got to see to believe.
Method Seven offers two lines of grow glasses for HPS lighting environments. Method Seven Rendition HPS delivers "Perfect Color" for the world's ultimate grow experience in the intense yellow spectrum and harsh conditions of HPS lighting. They deliver absolutely the highest available optical clarity and ability to absorb infrared (heat). These are THE best lenses for the professional working extended hours under HPS or the passionate hobbyist who simply wants the best. The “plus” silver coating option makes our glass lens even better for working in high wattage environments or crossover use outside. Plus, they just look cool :-) Our patent pending formulation is manufactured with the highest quality German durable mineral glass to provide perfect color, perfect clarity, and 100% UV protection.
Our synthetic lenses are manufactured for Method Seven by Carl Zeiss using Method Seven's unique lens technology and provide optimized color under HPS. And they provide exceptional clarity due to the high optical standards obtained by Carl Zeiss. They are very lightweight and unbreakable. We recommend our synthetic lenses to anyone with one grow light or who spends minimal time working under lights. The value of our synthetic lens makes these products great for outfitting larger crews who are working under lights but may not be making critical plant health and harvest decisions. Available either uncoated or silver coated (combining your indoor grow and outdoor lifestyle), 100% UV protection, and great value.
Both glasses provide benefits that clearly exceed the performance of all competitors.
Sunglasses are not for grow rooms!
Grow rooms have lots of light, but it's not broad spectrum. Great for plants, but not your eyes. The rods and cones in your eyes need broad spectrum light to focus, see shapes, notice movement and see color. When you wear sunglasses, you make this worse - you darken all the light, so you squint less, but you still can't see color and it's even more difficult to focus. Things look muddy. Your brain struggles to compensate. That's where fatigue and headaches come from.
Method Seven Optics filter the harsh lighting and bring balanced color to your eyes. It's like working in full daylight, naturally. you can see foliage properly, spot pests and deficiencies early and easily. your brain relaxes. No headaches, no strain, and no long-term damage. Our glasses even eliminate the strobe effect produced by most HPS ballasts. And there's no adjustment period when you walk out of the grow room. With Method Seven, you can work with accuracy, comfort and safety.
See. Believe. Your eyes are worth it!
Cheap lenses distort light as it enters your eye. Like seeing double, or slightly cross-eyed, or just hazy. Focus and clarity are compromised. You may not notice it right away, but then again you can live for several minutes with a plastic bag stretched over your head. Doesn't mean you should do it.
Method Seven Rendition lenses are made in Germany from glass, melted in six ton batches to achieve perfect clarity with your Patent Pending formulation. They are asymmetrically ground and polished and built into custom frames in Italy. This is perfection.
Our distortion free polycarbonate and nylon lens are made by Carl Zeiss. The absolute best synthetic lenses in the world. Your eyes are worth it!
Custom RX available for all spectrums.
HID lights are serious!
UV damage is cumulative, like a small sun-burn on your cornea and retina with each exposure. No one talks about UVC from the Sun because it's filtered by the upper atmosphere. Surprise! It's the most dangerous UV and is produced by most HID lights. Method Seven lenses protect from ALL harmful UVA/B/C rays. Don't risk it. You think going to the dentist is expensive and painful, try a cornea replacement. PS: for extended hours in a grow room, a visor and sunblock is also a good idea...
Method Seven technology blends incredible color balancing for each of the standard grow lighting spectrums (HPS, Metal Halide, LED, Sun) with exceptionally high quality lenses that provide the best in optical clarity. Additionally, Method Seven protection removes all harmful UV A/B rays like most others but additionally also removes harmful UVC rays which are filtered out of sunlight by the upper atmosphere, but pose a significant hazard under grow lighting.
Many growers suffer through unnecessary stress, fatigue, decreased yield, and even permanent eye injury from using sunglasses or cheaper knock-off grow room glasses. At best, even premium sunglasses attenuate (decrease) excess light in the grow room but do a horrible job of color balancing in indoor lighting environments, leading not only to discomfort and stress, but also to poor viewing and maintenance of your plants. Cheap grow room glasses do an okay job of color balancing, but typically have very poor optical quality and inadequate protection from UVC rays.
Treat yourself and your grow to Method Seven quality and style!
Q: Do Method Seven Glasses work outdoors?
A: YES! YOU CAN WEAR YOUR METHOD SEVEN'S OUTDOORS TOO! Method Seven Technology blocks and completely protects your eyes from all harmful UVA/UVB/UVC light. Our glasses are appropriate to wear outdoors under any conditions which you choose. The HPS spectrum lenses filter out less visible spectrum light than most medium and dark sunglass lenses which means they are a great choice for lower light conditions, like mountain biking in the trees or skateboarding in the early morning, but they may not be your first choice for snowboarding on a sunny day when conditions are super bright. In very bright outdoor conditions the MH Silver Plus+ lens is a fantastic outdoor lens. Made from unbreakable polycarbonate; it’s a great choice for action sports. (LED glasses are not recommended for outdoors).
Q: Why bother with grow glasses?
A: SEE. BELIEVE. While HPS, Metal Halide, and LED lighting can provide effective lighting solutions and deliver plants the light energy needed for prolific vegetative growth, they also create a hostile working environment for the human eye. Humans see best under the balanced spectrum and light levels of natural daylight conditions. Grow room lighting produces extreme conditions of excess light, very unbalanced light from unique spectrum of each artificial grow light source (HPS, LED, MH), and dangerous UV radiation from UVA/UVB/UVC.
Sunglasses help attenuate (reduce) the excess light, but do nothing to help color balance the stressful and eye fatiguing spectrums of indoor garden lighting. Cheap grow glasses offer some improvement here, but usually at a much lower optical quality than good sunglasses. Both might not protect from UVC radiation which is not a significant concern in natural sunlight due to absorption by the earth's atmosphere but which is a concern in the modern grow room.
Only Method Seven provides definitive color balancing with options for all common indoor lighting sources, exceptional clarity, and 100% UVA/UVB/UVC protection. Don’t risk using sunglasses or cheap grow room glasses!
Q: Why are Method Seven's so superior to other grow glasses?
A: SEE. BELIEVE. Grow room lighting produces extreme conditions. The hazards include excess light, very unbalanced light from the unique spectrum of each artificial grow light source (HPS, LED, MH), and dangerous UV radiation from UVA/UVB/UVC. Ballasts used by HPS and MH grow lights also creates a high frequency strobe effect in the light from these bulbs. This is not immediately obvious to the conscious mind, but is very stressful to your eyes and impedes ability to easily focus on shapes and detect movement. Working in these environments without appropriate eyewear results in eye and general fatigue, inability to correctly monitor plants, and even permanent injury to your eyes. Method Seven Optics are designed and engineered specifically and carefully for these conditions.
All Method Seven lenses are made from either premium German mineral glass or high quality synthetics manufactured to our custom standards by Italy's Carl Zeiss - world leaders in optics for over 100 years. All are asymmetrically tuned bringing distortion free focus and clarity to your eyes. Rendition glass lenses virtually eliminate the strobe effect, and Carl Zeiss synthetic lenses reduce this to physiologically low levels.
Other grow glasses attempt to color balance the extreme light spectrum of the grow room with varying degrees of success, though even those with decent light balancing typically use cheap plastic lenses with very poor clarity that distort light and are hazy or blurry. With cheap grow room glasses, your eyes and brain work overtime to compensate and you can experience fatigue, see spots, get headaches and in some cases experience damaging UV radiation.
Your eyes and health are very important. So is getting the most out of your grow. Don’t risk using sunglasses or cheap grow room glasses!
Q: Where are Method Seven glasses manufactured?
A: SANTA CRUZ INSPIRATION, GERMAN & ITALIAN CRAFTSMANSHIP. Our Rendition Perfect Color HPS mineral glass lens is made with a patent pending formulation, melted in six ton batches in a century old German factory, and ground, polished, cut and hardened in Italy.
Our synthetic lenses are made by Carl Zeiss - world leaders in optics for over 100 years. They are asymmetrically tuned bringing distortion free focus and clarity to your eyes.
Our frames are made in Italy. Final assembly of glasses into frames is also done in Italy. Packaging of glasses, carry case, wiping cloth, and boxes is done in Italy or in Santa Cruz, California.
Q: What's the story with Rendition "Perfect Color" HPS lenses?
A: COLOR BALANCING. We developed a proprietary blend of rare-earth elements that are bonded within molten glass at the molecular level. The result is canceling of a precise nanometer of light energy from the High Pressure Sodium spectrum. The lenses also selectively filter the remaining light spectrum to create the white balanced light your eyes need for maximum performance and comfort. The specific density of the glass lens also absorbs a substantial amount of infrared radiation resulting in additional comfort. Rendition Perfect Color HPS lenses provide the ultimate in color balancing, optical clarity, and protection to allow you the ultimate in comfort, visual acuity, and productivity while working with your grow.
Up your game as you as monitor plant health and correctly perceive the color of your plant leaves and the things that threaten your grow - pests, disease, rot, mildews, and mineral deficiencies and excesses - that are often hidden by the harsh lighting environment. The Rendition lens reveals color precisely enough to use a PH test strip while in the grow room. All without turning your HPS lighting off or walking your plants, or your testing equipment into daylight. (If you are the kind of person who wants to know the details, you can read about the amazing science behind in links further down this page).
OPTICAL CLARITY. Rendition Perfect Color HPS lenses are made from mineral glass which is melted in six ton batches in a century old German factory, and ground, polished, cut and hardened in Italy. They provide the ultimate in distortion free focus and clarity to your eyes.
PROTECTION. Like all Method Seven optics, Rendition lenses provide 100% protection against not only UVA and UVB radiation, but also from UVC radiation lacking in normal daylight but prevalent under grow-room lighting. Rendition lenses are also the only grow lenses in the world that eliminate virtually all of the high frequency strobe effect inherent under HPS grow lights due to the way ballast and HPS bulb product light (the strobe effect is not immediately obvious to the conscious mind, but is very stressful to your eyes and impedes ability to easily focus on shapes and detect movement, and is a huge contributor to eye fatigue when working for prolonged periods in and HPS lighted grow room).
Experience "Rendition Perfect Color" under HPS lighting - and work unconstrained in spite of that environment.
Q: Why does Method Seven offer so many options?
A: WE PROVIDE AN EXTENDED ASSORTMENT OF GLASSES BECAUSE... gardeners employ a variety of lighting types and combinations of lights to work their craft! Each type of light produces its own unique spectrum that is very different from the light levels and balanced spectrum of daytime sunlight which works best for our eyes. We make optical solutions for each of the most common of these lighting spectrums. Our glasses allow you to regain the comfort and high quality visual results you would experience in an outdoor garden environment. We also offer clip-ons for people who need prescriptions"
COLOR, CLARITY, PROTECTION
All Method Seven glasses provide outstanding Clarity, and 100% UVA/UVB/UVC protection.
Optics & Spectrum Info
NATURAL SUNLIGHT AND WHITE BALANCED LIGHT. Sunlight is composed of the full, balanced distribution of light across the spectrum of visible wavelengths from 390 to 750 nm - a magical distribution of reds, yellows, greens and blues - all the colors of the rainbow. Sunlight's even distribution of all wavelengths of light across the full spectrum produces naturally “balanced white light” (BWL). Our eyes and brain need this color balanced light to function optimally without stress, discomfort, fatigue and sometimes permanent damage. This broad spectrum of light allows us to see natural looking colors and to also easily recognize shapes and motion. The sunlight spectrum also includes invisible and dangerous UV (ultra violet) and invisible and fatiguing IR (infra red) wavelengths.
GROW ROOM LIGHTS
Each grow-room light source (HPS, MH, LED) provides a VERY imbalanced spectrum of light, with a vast majority of the light occurring in just a few wavelengths of the spectrum typical of the chemistry and physics of that light source. Plants still grow well under these imbalanced light sources and aren't negatively affected, but human eyes and brains are.
COLOR, CLARITY, PROTECTION. ONLY METHOD SEVEN DELIVERS ALL THREE.
The greater productivity, comfort, and safety, the grower needs grow glasses that filter the harsh, unbalanced light of the grow room to create BWL (balanced white light). Each lighting spectrum (HPS, LED, MH) needs its own exacting solution. Method Seven Optics have formulations to filter out the specific wavelength spikes in the spectrum of each of these common grow lightings sources, providing the wearer white balanced light within the very unbalanced environment.The lenses must do this without reducing the optical clarity of the naked eye, or the reduced optical clarity from the lenses create a different set of physiological issues for the wearer. For short term comfort and long term health, lenses must protect the eye from 100% of the harmful UVA/UVB/UVC radiation of the grow room and reduce IR exposure to the eye.
HPS lighting creates and radiates a huge amount of light. The frequent electrical excitation and decay of electrons in the sodium atoms generates the vast majority of total light output at a specific "yellow" wavelength around 590 nanometers. This wavelength is a very suitable energy source for plants to use for photosynthesis and growth, and light and ballast costs have traditionally been low. HPS lights use considerable electricity and produce considerable excess heat. The yellow spike of HPS lights is especially challenging to our eyes due to the poor spectrum, the exceeding poor yellow / blue ratio of the light that impacts the functioning of the rods and cones in our eyes, and the high frequency "strobe effect" from the ballasts (more details elsewhere on this page).
Unlike most HPS lamps, the light spectrum produced by commercially available LED equipment varies between manufacturers and is dependent on the combinations of diode, amperage, magnification and a host of design considerations. The best LED spectrums for optimum plant growth typically produce a distinctive magenta color appearance.
MH bulbs produce light that's strongest at the blue end of the spectrum resulting in a stark, bright white light. MH bulbs tend to be very bright, and glasses need to appropriately attenuate (decrease) total light to the eye in addition to providing color balanced light and 100% UVA/UVB/UVC protection.
Our eyes evolved to function best under daytime sunlight with its full, balanced distribution of light across the full spectrum of red, yellow, green and blue wavelengths from 390 to 750 nm. Our eyes and brain need this color balanced light to function optimally without stress, discomfort, fatigue and sometimes permanent damage. This broad spectrum of light allows us to see natural looking colors and to also easily recognize shapes and motion.
"BALANCED WHITE LIGHT"
When reproducing the full sunlight spectrum artificially, the spectrum is called "balanced white light" (BWL). Each type of grow light (HPS, LED, MH) produces a spectrum very far from white balanced light. Photographers learned long ago that the color of light on an object changed the way a camera/film registers the color of the object, just as the color of light on an object changes the way our eyes perceive the color of that object . With the advent of modern light metering and photo processing software, photos can be white balanced after the fact. Photographers have created a process where they photograph a specific color of white paper at the same time they take a photograph, and later adjust the finished photographs (using photo software like Photoshop) until that white paper looks the correct shade of white again. This allows the other objects photographed to appear the correct color too.
When looking at something under a spectrum other than balanced white light, your eyes work hard and partially color correct what they see. The more unbalanced the spectrum, the harder your eyes work and the less they can successfully compensate. Look at a sheet of white paper under grow lights, and you will notice that it doesn't look even close to white, instead you see the unbalanced color spikes of the grow room light source. Your eyes can't come close to compensating for the extreme lighting environment of indoor grow lights. Look at that same piece of paper with Method Seven glasses, and see the exact shade of white you see outdoors under natural sunlight! For more technical information about color balancing, eye physiology and specific Method Seven products, see the "Color Perception & M7 Color Balancing" section lower on this page.
COLOR, CLARITY, PROTECTION
Light balancing is only one of the challenges for optical products for the indoor grower. Only Method Seven delivers products for different light source spectrums with state of the art color balancing, optical clarity, and 100% UVA/UVB/UVC protection.
Method Seven Rendition Perfect Color HPS lenses are made from high grade mineral glass. The elements added to the glass are atomically bonded into the crystalline structure. There are no emulsions or dyes to interfere with optical clarity. Method Seven's synthetic lenses likewise provide exceptional optical clarity. These lenses were developed in partnership with Carl Zeiss, a 100 year old Italian lens manufacturer well known for the optical quality of their lenses.
The best glass lens sunglasses on the market match the optical clarity of the Rendition mineral glass lenses (but don't color balance for indoor growing, and may not protect from UVC radiation). Less expensive sunglasses and cheap grow glasses have poor optical quality and contribute to eye stress and fatigue.
Eye Protection & safety standards:
PROTECT YOUR EYES! Find yourself constantly squinting in the grow room? Over time constant exposure to high levels of UV and infrared radiation leads to irreparable eye damage. Loss of color perception, cataracts, and the destruction of your night vision are possible. All of our lenses blocks all harmful invisible wavelengths (UVA, UVB, UVC and Infrared). Your plants require these invisible wavelengths to flourish. Your eyes certainly don’t.
But that's not the whole story. Cones and rods within your eyes control the eyes ability to focus and function best at light wavelengths very different from the indoor grow environment. New science proves that the eyes extra effort to focus and correct for excess yellow from HPS lights causes a host of eye strain and health problems. Rendition lenses balance the light in a way that allows your eyes, brain, and body to function correctly again. This results in drastically less mental strain and fatigue. Less fatigue equals better decision-making and a pleasant experience in your grow room.
Method Seven glasses meet or exceed international safety tests for optical quality, clarity, breakage and UV protection.
HPS lighting story:
High Pressure Sodium (HPS) lighting has long offered a cost effective solution for some industrial applications such as the lighting of warehouses and for Grow Room lighting. HPS lighting also creates visual problems for people working within its environment. The details of these visual problems are discussed in our eye physiology section. But in general, HPS lighting causes significant decrease in color perception and ability to focus on shapes and motion. The "strobe" light effect caused by the high frequency, cyclical variation in power from the HPS ballast to the bulb causes a similar high frequency variation in light intensity which also has negative impact on our eye's ability to function comfortably and effectively under these lights.
HPS lighting creates and radiates a huge amount of light. The frequent electrical excitation and decay of electrons in the sodium atoms generates the vast majority of total light output at a specific "yellow" wavelength around 590 nanometers. This wavelength is a very suitable energy source for plants to use for photosynthesis and growth.
This same concentration of yellow light makes it difficult for an individual to see properly. Humans see best in natural sunlight, or in “Balanced White Light” (BWL). BWL light, like natural sunlight, covers the entire visible spectrum of 390 to 750 nm. This broad spectrum of light allows us to see natural looking colors and to also easily recognize shapes and motion. Under HPS lighting our eyes are saturated with yellow light and we are unable to recognize any other colors.
Human eyes also require a certain ratio of blue light (around 505 nm) to yellow light (around 555 nm) to be able to recognize shapes and to detect motion. HPS lights provide some of this blue light, but in far to low a ratio compared to the prevalent yellows, and this profoundly degrades our ability to focus. This point will be explained further in the discussion of “rods” and “cones.”
COLOR, CLARITY, PROTECTION. METHOD SEVEN DELIVERS!
Others can try to copy but fall short: Method Seven developed the world's first HPS grow glasses and offers HPS glasses with patent pending Rendition Perfect Color HPS technology with German mineral glass or high optical quality synthetic lenses developed with Carl Zeiss (a world leader in high quality optical lens production). Only Method Seven delivers finished glasses of incomparable style and quality and meets your needs for Color, Clarity, Protection!
LED lighting story:
LED (light emitting diodes) grow lights are a relative newcomer as source for indoor horticultural purposes. They are the up-and-coming state of the art. Initial light / fixture costs tend to be higher than HPS and MH, but ... these costs can often be recouped quickly due to much lower energy consumption per lumen, less excess heat in the grow room, and the very long lift of bulbs. Unlike most HPS and MH lamps, the light spectrum produced by commercially available LED equipment varies between manufacturers and is dependent on the combinations of diode, amperage, magnification and a host of design considerations. The best LED spectrums for optimum plant growth typically produce a distinctive magenta color appearance. Method Seven chose Black Dog LED, considered an LED market leader, as the benchmark spectrum for design of the LED specific lens formulation.
The Method Seven LED Optics will balance color optimally under Black Dog LED lights, but has been tested with a number of other commercial LED lights and functions exceptionally well with all other brands tested to date. Color correction might vary slightly with alternative equipment (imperceptible in most cases) but in all cases Method Seven Optics will protect against all UV damaging ray regardless of LED brand.
METHOD SEVEN OFFERS THE WORLD'S FIRST AND ONLY LED BALANCING GROW LIGHTS.
Color, Clarity, Protection. Method Seven delivers!
Metal Halide lighting story:
Historically, in contrast to HPS lighting, Metal Halide lamps have had a higher initial cost but are typically slightly more efficient, produce less (but still considerable) heat, and have a broader, more diverse spectrum of light for plants. MH bulbs produce light that's strongest at the blue end of the spectrum resulting in a stark, bright white light. MH lighting may prove less difficult for the human eye than HPS, but still causes considerable eye strain and great risk from UV radiation. MH bulbs tend to be very bright, and glasses need to appropriately attenuate (decrease) total light to the eye in addition to providing color balanced light and 100% UVA/UVB/UVC protection.

For those who seek adventure, exploration, and discovery, the great outdoors beckons with its vast and magnificent beauty. If you take pleasure in observing birds, trekking, or spending time in the wilderness, then there is no experience as delightful as engrossing oneself in the splendor of the natural world. One tool that can enhance your experience and bring you even closer to nature is a good pair of binoculars.
It is crucial to have a good understanding of how binoculars actually function. Essentially, binoculars utilize a combination of lenses and prisms in order to enhance the image and bring it nearer to your eyes. The most common types of binoculars are porro prism and roof prism binoculars. Porro prism binoculars have a classic design, with the objective lenses set further apart than the eyepieces, while roof prism binoculars have a more streamlined design with the lenses in a straight line.
Two numbers are typically used to describe binoculars - magnification and objective lens size. Magnification refers to how many times closer the image appears through the binoculars compared to what a person would see with the naked eye. Objective lens size refers to the diameter of the larger lenses on the binoculars, which means the larger the size, the more light can enter and the brighter the image will appear.
Another important consideration when choosing binoculars is field of view, which is the width of the area one can see through the binoculars. Eye relief is also important, as it refers to how far away your eyes can be from the eyepieces while still seeing the entire image.
Choosing Binoculars for Specific Outdoor Activities
Bird watching: When it comes to bird watching, you'll want to choose binoculars with a magnification of 8x or 10x and a wide field of view to make it easier to track fast-moving birds. Look for binoculars with a close focus distance of 6-10 feet, as this will allow you to see details on nearby birds.
Hiking and camping: For hiking and camping, you'll want binoculars that are lightweight and durable, with good water resistance to protect them from the elements. A magnification of 8x is usually sufficient for these activities, and a wide field of view is also helpful for spotting wildlife and taking in panoramic views.
Astronomy: Binoculars can also be a great tool for stargazing, and there are specific features to look for in binoculars for this purpose. Aperture size is the most important consideration, as it determines how much light the binoculars can gather and how bright the image will appear. Look for binoculars with an aperture size of at least 50mm. Magnification is less important for astronomy, so a lower magnification (around 7x) is usually sufficient. Finally, tripod compatibility is important, as it will help keep the binoculars steady and reduce hand shake.
Tips for Using Binoculars Outdoors
Once you've chosen the right pair of binoculars for your outdoor activity, it's important to know how to use them properly to get the most out of your experience. Here are some tips for using binoculars outdoors:
Proper focusing techniques for different scenarios: Practice adjusting the focus on your binoculars for different distances and lighting conditions. Learn to use the focus wheel to fine-tune the focus, and adjust the diopter if necessary.
How to hold binoculars steady: It's important to hold binoculars steady to prevent shaking and ensure a clear image. Use both hands to hold the binoculars, and brace your arms against your body or a solid object like a tree trunk or a rock. You can also use a tripod or monopod for additional stability.
How to adjust for eyeglasses or contact lenses: If you wear glasses or contact lenses, you'll need to adjust the eye relief on your binoculars to get the best view. Most binoculars have eyecups that can be folded down for eyeglass wearers or left up for those without glasses. If you wear contact lenses, keep a spare pair with you in case you need to remove them and use the binoculars.
Choosing the perfect pair of binoculars for your outdoor activities can greatly enhance your experience and help you connect more deeply with nature. By understanding the different types of binoculars available and the features that are important for your specific activities, you can choose the right pair for your needs and make the most of your time outdoors. Remember to practice proper focusing techniques, hold your binoculars steady, and adjust for eyeglasses or contact lenses to get the best possible view. Happy exploring!


Today, since a lot of the people have turned to digital photography, they are using more of the available digital photography guides in the market. And according to the most effective photography guides, the Canon EF 75-300 mm is the best lens photographers can possibly have. The Canon EF 75-300 mm is actually the pioneering camera lens that is produced by Canon. It is the most saleable camera lens because of its main feature which is image stabilization. It has other top notch features, but image stabilization is its best and the one that distinguishes it from the rest.
With image stabilization, the photographers are allowed sigma cheap lenses to handhold two f-stops much more quickly, as compared to other lenses that do not have this particular feature. This is a very good advantage for Canon EF 75-300 users since it is very costly to have to purchase a new lens that has a two-stop quick aperture. This particular lens is also wide open on all the necessary focal lengths and soft. Just because it is soft, it does not necessarily mean that it is not sharp because it can actually zoom from 70 right up to 300 mm. The corners are the softest parts, since they are accounted to 70 mm. The lens, at its front, can also be rotated as it moves out if the photographer is trying to focus on an object that is very close.
Today, this particular lens is being widely used by professional photographers all over the world as it is perfect for shooting different ranges of photography, such as nature, people, pets, and even portraits. Although it may seem like such an effective digital photography item, the Canon EF 75-300 mm is actually one of the most affordable cameras to be ever released by Canon. In fact, experts in photography consider it as one of the most economical prices. Simply put, this particular lens is definitely a great bargain.
The part of the lens that is responsible for making the auto-focus feature quicker and quieter is the USM. It has a developed zoom system that allows zooming to be a much smoother venture. It contributes to a wonderful optical structure of thirteen elements, as it focuses fabulously and clearly even with close-up images, from nearly two meters up to nearly five feet only. Many photographers today are using this particular lens for their works of art since the results they have acquired look absolutely beautiful.

Thermal imaging IP cameras are now in high demand in combat zones. They ensure timely deterrence of penetration by sabotage and reconnaissance forces and enemy equipment. Surveillance is carried out remotely and invisibly — the operator’s data is transmitted over the network, i.e. without risk to human life. Combining video analytics to classify objects by type (person/vehicle) and high resolution, thermal imaging cameras work proactively — significantly improving safety over long distances, in places with poor visibility, including in the dark or in smoke. Contrasting images are especially useful in densely built-up areas, where it is extremely difficult to track the movement of enemy forces.
Therefore, thermal imaging cameras have proven to be useful for covering the city perimeter, as well as critical infrastructure facilities, such as thermal power plants, nuclear power plants, military facilities, etc.

There are many benefits to wearing polarized sunglasses. Designed to reduce glare created by the sun on the road or the surface of the sea. This is because most glare occurs when light is reflected off surfaces in all directions. Polarized lenses filter out horizontal lights while letting vertical light through, with the result of reducing glare. Fishermen report that it makes the ocean more transparent and they can even see fish beneath the surface more easily while wearing them.
But this man claims that it helps you see more than hidden objects in the sea. With the help of polarized sunglasses, he’s seeing whatever is hidden… in the sky.
WATCH VIDEO HERE
In the video, a man shows a clear blue sky in Iowa, then holds ups pair of polarized fishing glasses over the scene. When the lenses drop over the screen, you can see tiny glowing shapes floating and zipping around in the sky.
What are they? No one is quite sure. Some viewers insist that what he’s looking at are merely scratches in the lenses, but that explanation does not quite wash, as the objects move independently from each other.

Others report seeing the same kinds of things when they look through their own polarized lenses. “We were so in shock at what we were seeing and then we knew no one would ever believe us. We Google searched and haven't found anything that was exactly what we saw, but this was it!”
Another commenter says they’ve seen similar things in the skies of Alabama.
But some are still skeptical. If UFOs have such amazing cloaking technology, how can they be beaten by a simple pair of sunglasses? Well, maybe they just don’t expect anyone to look.

Holographic mesh Screen projection is a kind of display form with the aid of projection, spotlight and so on. It's still inseparable from the solid imaging medium, a thin screen like light yarn,it is made of thin cotton cloth or chemical fiber materials with mesh holes. It can be extremely fine wire mesh, steel wire mesh, or gauze that is not easy to be seen by the naked eye,it can provide a good imaging visual effect reflection. In large-scale display, it also expands the sense of space level of the stage, enhances the interaction between actors and videos in the performance, and make the performance more attractive.
Holographic Screen projection expands the space level of stage.The screen is light and transparent, and can be hung in all positions of the stage. At the same time, the tilt angle of the screen can be determined with the projection angle, which can make the screen more perfect and form a good imaging visual effect.


Bauch & Lomb & Hardware Ben Vision — cataract surgery
I had cataract surgery in 2014 in both eyes. In my first visit to Dr. I was told if I would like to have NGLs lens which is advance technology and I will have significant of changes in my vision after the cataract surgery. Meaning I will have better vision with NGLs lens than regular lens. My insurance company will not cover the charges and it will cost me $2500.00 for each eye.See the Top 10 Worst Companies in Old Bridge, NJ
I agree to pay for that thinking, I will have better vision. It’s been less than 60 days for my Right eye surgery as of today. The clear vision is less than three feet. It was Dr. who decided CRYSTAL LENS for implant. I guess he did it. Not sure because I never show the Lens. But I know one thing that with Dr. S visit and lens cost I have paid now more than $5500.00 I would like to know if there is any class Action law suit against the false marketing for the Doctors and company?

Competitive Analysis for each chapter segment
Section on recent mergers & acquisitions
The optical biometry device market is expected to grow over the forecast period due to sustained expansion of the number of units sold. Optical biometry devices are newer than ultrasound A-scans and pachymeters and are used in the same settings as these more traditional devices. In cataract surgery offices, optical biometry tends to be used alongside ultrasound equipment. The relatively new technology has not replaced the market for ultrasound devices because there remains a subset of cases for which ultrasound is a more effective measurement technique. As such, the market for optical biometry devices is driven more by the expansion of new and existing cataract surgery practices and less by the replacement of ultrasound devices with the more accurate alternative
With growth in the number of cataract procedures resulting from the aging population, practices are expected to continue to expand their capacity over the forecast period. In addition, new offices are expected to open at a rate similar to the growth of the patient pool. Prices, however, have established consistent values and will only see slight erosion throughout the forecast due to competition.
Optical biometers are partial coherence interferometry devices designed to generate a range of biometry measurements as well as to assist with intraocular lens (IOL) calculations. Optical biometers are capable of taking multiple measurements including axial length, anterior chamber depth, corneal thickness and lens thickness. All measurements are taken at a single optometry or ophthalmology station. Contact with the cornea is not required for the functioning of optical biometers, which improves measurement accuracy.

An advanced generation of parabolic trough mirrors makes solar thermal power plants even more efficient
Flabeg FE GmbH, the international market leader and manufacturer of solar mirrors, has developed a new generation of parabolic trough mirrors. The new mirror combines higher strength with a superior precision of curvature and highest solar reflectivity.
“Power plant operators benefit in more ways than one from our mirrors,” explains Franz Reimer, Head of Flabeg Research and Development Division, “The enhanced performance of the mirrors means that the effective solar area can be made smaller. The need for collectors and their components is reduced, making further cost savings possible.”
The relevant quality parameter for accuracy, the focus deviation (FDx) today is lower than 6 mm – an improvement of more than 1 mm compared to the already outstanding quality set by Flabeg mirrors in 2013. In combination with a solar reflectivity of more than 94.5% Flabeg again sets the benchmark for the CSP industry.
As a pioneer in the field of solar technology with a worldwide network, Flabeg produces flat and curved mirrors for all CSP technologies – Parabolic Trough, Dish Stirling, Power Tower and Linear Fresnel Systems, as well as customized mirrors for CPV applications. Thanks to the latest bending and coating technologies, Flabeg solar mirrors provide the highest degree of precision and reflectance .The extremely robust mirrors were installed in the first commercially operated power stations in the early 1980s. These mirrors are still in daily operation today, without any decline in performance or efficiency. Flabeg has been expanding its skills in the area of engineering services and project development support in parabolic trough technology. The company has developed a new collector design – the Ultimate Trough Collector. The design goal, a 20-25% higher cost efficiency compared to currently available technology is proven in a full demo-loop, integrated and operated in a commercially operating solar thermal plant in the US since 2013. Flabeg received the SolarPaces Technology Innovation Award for the Ultimate Trough in 2013.
FLABEG FE GmbH is present as Silver Sponsor at the SolarPACES 2014 conference to be held in Beijing from September 16 to 19.

Eye Surgical treatment
Eye Surgical treatment has become a mainstream approach of vision modification, as well as this short article will explain the benefits as well as drawbacks of 3 various techniques being provided to the clinical customer.
Lasik Eye Surgery
LASIK is the phrase for Laser-Assisted Sitting Keratomileusis as well as is an eye surgical system which permanently fixes vision by eliminating a thin layer of the cornea. This procedure functions best on individuals with moderate to high degrees of nearsightedness (nearsightedness), low to moderate levels of hyperopia (farsightedness) as well as astigmatism associated with nearsightedness, as well as who have thick corneas. It is one of the most well-known medical vision modification method.
Individuals with regular eye sight see objects plainly since images are brought into a proper centerpiece by the cornea and lens of the eye. Preferably, the cornea's curvature is evenly matched to its size in a typical eye. Individuals with astigmatism, nearsightedness or hyperopia have off-and-on formed corneas, so the objects seen are not concentrated correctly. LASIK adjustments corneal shape by exact elimination of corneal cells, and by doing so corrects the eyes' focusing power.
There are, nevertheless, risks to LASIK eye surgical procedure.
There is a remote possibility of complete loss of vision. If this occurs, it is usually since the person had a pre-existing condition which must have averted the surgical procedure to begin with, such as maternity, cataracts, arthritis, diabetes, glaucoma, or lupus. People with large pupils are also poor candidates for LASIK. Dry eye syndrome will be worsened by this procedure.
A few clients grumble that they completely see "ghost" photos, have obscured vision, lessened contrast as well as negative evening vision. When LASIK was first introduced, 5% of individuals had post-operative complaints; however, improvements in the procedure have actually created this rate to go down to much less compared to 1% if LASIK is done by skilled specialists and also individuals are correctly evaluated before surgical procedure. If problems do happen, they could commonly be resoved by a retreatment.
FDA has actually accepted LASIK laser eye surgical procedure given that 1998. While there are a great deal of satisfied patients, there are however no long term researches concerning its results. Realize the limitations and the risks of LASIK eye surgical treatment before you sigh for the treatment.
Though much less popular, these small implants can click here for more improve vision in clients with moderate to moderate nearsightedness without the threat of permanent eye damage blog integral in the cells elimination strategy of LASIK. Intacs are semi-circular disks dental implanted in the cornea which extend it to think a flatter form. Though a little much less specific compared to LASIK, they are removeable and exchangeable, so if the person has an unanticipated over- or under-correction, the dental implant could be gotten rid of as well as one more of a different size inserted to get the wanted improvement. The implants lie beside the cornea, so the main visual area is entirely undamaged as well as undamaged, and the toughness of the cornea is undiminished, making it a far better choice for pilots as well as those who engage in call sporting activities where eye injury is an opportunity.
Intacs are unsuitable for severe nearsightedness and also greater than minor astigmatism (1.00 diopters), as the cornea could just be stretched up until now. If the Intacs are removed, vision go back to its preoperative degree. Besides vision improvement, Intacs are likewise utilized to treat keratoconus.
Intacs are FDA accepted as well as Ten Years researches have actually revealed no significant problems with Intacs and also very few individual grievances; nonetheless, since the treatment takes much more training compared to LASIK, there are fewer eye surgical procedure clinics using it. However, the Intacs web site offers a listing of experts in each state, as well a couple of in Canada, Europe and Mexico.
Since many individuals do not want to take the chance of LASIK and Intacs can not aid those with severe vision issues, intraocular lens implants (IOL) are a brand-new option authorized by the FDA in 2004 to deal with moderate to serious nearsightedness. The Craftsmen lens, manufactured by Ophtec, resembles the sort of lens implant used to recover vision following cataract eye surgical treatment.
The brand-new IOL, called the Craftsmen, is intended for only clients that have 2.5 diopters or less of astigmatism.
The fabricated lens does not replace the all-natural lens, however is put in front of it. The major problem discovered with the dental implant was the steady loss of endothelial cells in the corneas of individuals that obtained the implants. The endothelium is a layer of cells that line the undersurface of the cornea and are vital in maintaining the cornea clear. A three-year research revealed a consistent consistent loss of endothelial cells of 1.8 percent a year. Now, no one can predict whether this loss will proceed at the exact same price forever, or perhaps its influence on corneal function.
To minimize long-lasting impacts of the gadget on the corneal endothelium, the FDA is needing that the brand-new lenses be classified to define that they need to just be dental implanted in patients whose corneal endothelial cells are thick enough to endure minor cell loss.
Much more major issues were few: retinal detachment (0.6%), cataract advancement (0.6%), as well as corneal swelling (0.4%). The FDA is needing Ophtec to carry out a five-year follow-up survey of its implant clients to better examine the post-surgical incidence of cataract advancement, retinal detachment as well as other ophthalmic diseases.
The Artisan lens is intended to be a permanent implant.Though it can be gotten rid of operatively, vision could not always go back to just what it was before obtaining the lens. Because it does not affect astigmatism, patients with this problem could still need glasses.

3156 Bulb Size:
Four side-firing 1.5W-rated Osram LED chips, and one 5W-rated LED chip on top, which is projected by a lens for maximum effective brightness. The bulb is housed in a machined aluminum casing, which provides superior heat diffusion for long life.
Each of the four sides of this bulb contains three 5W-rated chips, and the top is fitted with four more under a projector lens. This is the brightest self-contained automotive LED bulb on the market, and is housed in an aluminum casing with a textured finish for maximum heatsinking properties.
2006-2010 Dodge Charger Model Years (921) use a quality inject-molded 921 terminal, with a sturdy base connector and proper pin alignment, designed for exact replacement of your factory 921 bulb. You will not need resistors for backup lights. Just replace the factory bulb.
2011-2014 Dodge Charger Model Years (3156) use a quality inject-molded 3156 terminal, with a locking base connector and proper pin alignment, designed for exact replacement of your factory 3156 bulb.
Included in your order is TWO BULBS
These LEDs illuminate in a crisp, cool, bright, white hue for maximum light output.
Diode Dynamics offers several brightness options so you can choose what fits you best. These options are listed by the design and the lumen output of each bulb:
921 Bulb Size:
(210 lumens) Slightly higher brightness than OEM bulbs.
(410 lumens) Much brighter than OEM bulbs.
3156 Bulb Size:
(310 lumens) Slightly higher brightness than OEM bulbs.
(510 lumens) Much brighter than OEM bulbs. These are bright!
Lumens. BUYER BEWARE!
Most sellers just provide "calculated" lumen numbers, based on the maximum potential brightness of the LED chips on the bulb. For example, if a bulb has five 10-lumen chips, they will rate it at 50 lumens. However, this is not accurate, as the design of an LED bulb does not get rid of heat fast enough to run the LEDs at maximum.
These "calculated" lumen ratings are much, much higher than the true, measured light output, so it will look like competitors' bulbs are brighter than ours. This is because Diode Dynamics does not provide inflated "calculated" numbers; we believe it is misleading. We test the actual brightness of the bulbs in our lab, to provide real lumen output measurements. Our measurements are accurate, but they are usually much lower than the misleading "calculated" figures.
Diode Dynamics uses only the highest quality LED chips in the production of its bulbs. This means only brand-name suppliers such as Epistar, Cree, Osram, and Samsung.
While Diode Dynamics bulbs may look the same as others on the market, most copycat bulbs use economy-grade LED chips in order to reduce costs. This greatly reduces the reliability and overall brightness of the bulb when you compare it to Diode Dynamics.
Although LED technology allows for extremely long bulb life, the market is flooded with cheap LED bulbs that fail prematurely due to inferior construction. The worst enemy of LEDs is excessive heat, and when bulbs are not designed properly, they do not disperse heat as well, leading to premature failure.
Off-brand, cheap bulbs exhibit poor solder uniformity, high levels of flux in the solder, uneven chip placement, low-gauge terminal wires, poor assembly, and bulbs held together with inferior adhesives. At best, solder joints will crack and fail on low-quality LEDs after a few weeks of use. In the worst case, these bulbs can damage housings as the extra flux and adhesive evaporates and creates a residue on the lens of the housing.
Diode Dynamics bulbs are produced with modern, computerized equipment, and only the best materials, to ensure complete uniformity, high quality, and long bulb life.
All Diode Dynamics products come with a 30-day satisfaction guarantee and a 3-year limited replacement warranty.

Apple, Google‘s phones and Samsung have long ruled the roost when it comes to slow-motion video, offering smooth 240fps support. Sure, we’ve seen the likes of Lenovo claim 960fps as a standard, but this was via ineffective software trickery.
Now, Sony has laid the foundation down for super slow-motion, announcing a new smartphone sensor capable of shooting at 1000fps.
“This newly developed sensor with DRAM delivers fast data readout speeds, making it possible to capture still images of fast-moving subjects with minimal focal plane distortion as well as super slow motion movies at up to 1000 frames per second (approximately 8x faster than conventional products) in full HD (1920×1080 pixels),” Sony wrote in a statement.
Sony’s new smartphone camera sensor offers incredible 1000fps video, but when will we actually see it in a device?
Otherwise, the sensor supports 4K recording, 60fps video and conventional 240fps slow-motion.
However, the real question is whether today’s smartphone chips are capable of processing a 1000fps video clip in the first place. After all, the Snapdragon 821 and 835 top out at 240fps as well as 4K/30fps.

Each frame is equipped with high-quality steel spring hinges, which provides maximum comfort when wearing glasses every day. Tishler frames fit perfectly. Given the specially designed frame combined with spring hinges, the glasses are extremely comfortable to wear and rest on your head. They are also performed in the version with corrective lenses. it is possible to install vision lenses in the frames. They are easy to wear. Contrary to the common opinion that wooden sunglasses are heavy, the experience of their customers says that they are extremely light and comfortable. Since a special birch air core is used when making the glasses, Tishler glasses offer excellent durability.


Biaggio’s research is focusing on condensed matter physics and photonics, using different kinds of lasers to investigate light-matter interaction in various systems.
In the condensed matter area, his research group is working on the investigation of organic semiconductors. These materials often consist of molecular single crystals and they generally work in an area of condensed matter physics that is markedly different from conventional semiconductors. Biaggio’s group has contributed greatly to advances in the understanding of the photophysics of one organic semiconductor that serves as a prototype material in the fields: rubrene. He and his graduate students published the first complete spectroscopy characterization of the material, the first visual observation of the diffusion of triplet excitons, also determined the connection between its photocunductivity and triplet exciton states. His group is currently investigating the properties of a quantum-entangled pair of triplet excitons that are generated after photoexcitation and wonder independently in the crystal by diffusing, while remaining in an entangled state from the point of view of spin. His work with Eric Wolf, a Lehigh undergraduate student at the time, lead to the first observation of fluorescence quantum beats in rubrene/
In the photonics area, Biaggio’s research lead to the development of a specific small-molecule organic material that can be easily combined with silicon photonics to create the optical equivalent of a transistor, a special waveguide device that can be used to control light with light (all-optical switching). This lead to the first ultra-high-speed demonstration of all-optical switching using the “DDMEBT” material, and to the later development of a general new paradigm for enhancing photonics circuits by homogenously filling nanometer scale gaps in silicon waveguides with a mall-molecule material using physical vapor deposition. Biaggio’s group is also doing general work in various areas of nonlinear optics, such as special coupled waveguides that can be used for frequency conversion in glass fibers, or the development of organic electro-optic modulators for integrated photonics.

In order to let users understand the company's formaldehyde odor control products intuitively: formaldehyde odor decomposition catalyst, do a tindal phenomenon experiment.
Dindal phenomenon experiment:
Materials: 1 laser pen, 1 cup of transparent water, 1 cup of company products
Methods: irradiate two cups with different liquid vertically with laser pen, and a light column will appear in the cup with formaldehyde odor decomposition catalyst!
1、 What is the Dahl phenomenon?
A: when a beam of light passes through the colloid, a bright "path" can be observed in the colloid from the direction perpendicular to the incident light. This phenomenon is called Tyndall effect;
英国物理学家约翰·丁达尔(John Tyndall 1820～1893年) ，1869年首先发现和研究了胶体中的上述现象。这条光亮的“通路”是由于胶体粒子对光线散射形成的。 丁达尔效应是区分胶体和溶液的一种常用物理方法。
John Tyndall (1820-1893), a British physicist, first discovered and studied the above phenomena in colloids in 1869. This bright "path" is due to the scattering of light by colloidal particles.  Dingdal effect is a common physical method to distinguish colloid from solution.
2、 Why is there a light column in the cup with catalyst?
A: because there are small solid particles in the solution. Small particles scatter light to see the light column. These indicate that there is a substance in our reagent.
在光的传播过程中，光线照射到粒子时，如果粒子大于入射光波长很多倍，则发生光的反射；如果粒子小于入射光波长，则发生光的散射，这时观察到的是光波环绕微粒而向其四周放射的光，称为散射光或乳光。丁达尔效应就是光的散射现象或称乳光现象。由于真溶液粒子半径一般不超过1 nm，胶体粒子介于溶液中溶质粒子和浊液粒子之间，其半径在1~100 nm。小于可见光波长（400 nm～700 nm），因此，当可见光透过胶体时会产生明显的散射作用。而对于真溶液，虽然分子或离子更小，但因散射光的强度随散射粒子体积的减小而明显减弱，因此，真溶液对光的散射作用很微弱。此外，散射光的强度还随分散体系中粒子浓度增大而增强。
In the process of light propagation, when the light hits the particles, if the particles are many times larger than the wavelength of the incident light, light reflection will occur; if the particles are smaller than the wavelength of the incident light, light scattering will occur. At this time, the light that the light waves radiate around the particles is observed, which is called scattered light or milk light. Tindal effect is the scattering phenomenon of light or milk light phenomenon. As the radius of the particles in the real solution is generally less than 1 nm, the colloidal particles are between the solute particles and the cloud particles in the solution, and the radius is 1-100 nm. It is smaller than the wavelength of visible light (400 nm ~ 700 nm). Therefore, when visible light passes through colloid, it will produce obvious scattering effect. For the real solution, although the molecule or ion is smaller, the intensity of the scattering light is obviously weakened with the decrease of the volume of the scattering particles, so the scattering effect of the real solution on the light is very weak. In addition, the intensity of scattering light also increases with the increase of particle concentration in the dispersion system.
The brighter the light column is, the more solid particles are contained in the solution, the higher the concentration is, and the better the treatment effect is.
3、 What is the solid in the cup?
A: it is made of food additives like stone powder, which can be dissolved in water. Therefore, it is non-toxic and harmless. So that the company's products are non-toxic and harmless, no secondary pollution.
4、 What is the use of small particle solids in cups?
Catalytic decomposition of formaldehyde into water and carbon dioxide.
5、 Why does small particle solid decompose formaldehyde?
A: small solid particles are between positive and negative charges.
Features: after illumination, one end of solid particles is positively charged and the other is negatively charged. The positive end oxidizes and decomposes formaldehyde into water and carbon dioxide.
1. The electron of oxidant is reduced
2. The reductant loses electrons and is oxidized
3. Formaldehyde is a reducing agent, which is oxidized to carbohydrates when electrons are lost.
4. Electrons are negatively charged subatomic particles.
5. The same charge repels each other and the different charges attract each other
Oxidation and reduction are the same process.

16mm film, mute, 10 mins 15 secs, looped.
Commissioned by Kunsthalle Bern, Switzerland.
Exhibited at Kunsthalle Bern, 2006, Van Abbemuseum Eindhoven, 2007, and Kunstmuseum Bern, 2008
(Made in collaboration with Pavel Buchler)
A moth circles a bright lamp in this unedited, looped film. It was filmed at four thousand frames a second using a camera normally employed in car-crash testing, in a specially constructed interior.
The film is projected onto a hanging frame, with the 16mm projector also clearly visible in the exhibition space. The lamp depicted in the filmed image slowly becomes a metaphor for the bulb within the projector, and the moth circling that light source thus becomes a symbol for the celluloid passing in front of that projector bulb.

Life without glasses - LASIK or lens? Comparison of methods
In Germany, more than 60 percent of people over the age of 16 now need glasses - and the trend is rising. Extensive VDU work, long reading in rooms with little daylight and wrong eating habits have led to an increase in ametropia in recent years. However, many adults are bothered by the glasses and they opt for surgical measures such as laser eye surgery or lens implants in order to permanently dispense with the unloved "nose bike". An overview of which method is suitable and when:
LASIK - method of choice for low ametropia
Correction with the laser is considered very safe today. LASIK stands for laser-in-situ keratomileusis and is a scientifically recognized method to correct nearsightedness up to minus ten, farsightedness up to three and astigmatism up to approximately minus five diopters. In today's Femto-LASIK, a wafer-thin layer of the cornea is first prepared with a laser. This layer, also called a flap, is folded aside and the exposed inner surface of the cornea is treated with an excimer cold light laser. Dr. Robert Löblich, ophthalmologist at Artemis Eye Clinics in Frankfurt explains what happens: "The laser changes the refractive power in the eye and thus corrects the ametropia." LASIK has been approved in Germany since 1990 and is the most experienced procedure. The procedure is not suitable for pregnant women or nursing mothers, as changes in the refractive power occur in the body as a result of hormone changes. LASIK treatments are not or only partially suitable for people with rheumatism or certain eye diseases.
Contact lenses in the eye
In order to enable people with severe vision problems to live without glasses, doctors use artificial lenses that correct farsightedness up to eight diopters and nearsightedness down to minus 20 diopters - also in combination with astigmatism. In doing so, they put an artificial lens in addition to their own. The natural ability of the eye to focus itself at different distances remains the same with this procedure as with LASIK. A cut the size of a pin is sufficient for the procedure. "Since no tissue is removed here, lens implants are also suitable for people with very thin corneas," says Dr. Praiseworthy. "And the procedure is reversible." Stable glasses values for at least one year are the basic prerequisite for the operation. In addition, doctors advise against such eye surgery for chronic eye infections as well as during pregnancy and lactation.
Extreme ametropia can also be eliminated
To treat extreme ametropia of up to -24 and +10 diopters, doctors use a combination of lens insert and LASIK. With all methods, patients enjoy their new eyesight shortly after the operation. "Many patients report that the operation gave them a completely new attitude towards life with an enormously improved quality of life," says Dr. (pm)
