As you get older (generally some time after age 40), you may begin to notice the problems with reading up close, including that feeling that your arms "aren't long enough" to hold a newspaper or magazine at a position where you can read it clearly.
If you already wear glasses, this generally means you will need to begin wearing multifocal lenses to continue to see clearly at all distances.
Progressive lenses are a newer technology that behave like bifocals, but have no visible line, and offer a younger-looking appearance and other advantages over bifocals, including:
- Progressive lenses are designed for people who just want one pair of glasses that can cover most of the things they do in the day without needing to take glasses on/off, or keep switching between different pairs.
- Progressive multifocal lenses provide a more natural correction - instead of having just two powers like bifocals, progressive lenses are true "multifocal" lenses that provide a seamless progression of many lens powers for all viewing distances.
How they work
Progressive lenses have a corridor of clear vision in the centre of the lens that varies in power depending on where you are looking through.
Finding the right progressives for you
Buying progressives can be confusing as prices vary from $100 through to $1,500 depending on where you go, and which lenses you select. The difference is not just in the price though - more expensive lenses have better technology designed to increase the clear areas, and improve the wearer's comfort.
At Mr Foureyes, we have taken an approach of offering a premium lens at a far more affordable price (from $350 for lenses or $550 for complete glasses with progressive lenses).
It is important that we see you in person so we can measure up your glasses to ensure the perfect fit. For this reason, this service is currently only available in-person at our Hataitai workshop.


Apple Posts Public Support Document About iPhone 5's Purple Camera Glare Issue
After hundreds of support threads, thousands of comments and many controversies Apple has finally responded to much reported iPhone 5′s purple flare camera issue. A lot of iPhone 5 users complained that their pictures which were taken using an iPhone 5 had purple glare on some spots. This happens only when your point your iPhone 5′s camera toward a bright light source and quickly take a picture.
Image Courtesy: TNW
Couple of days ago Gizmodo reported that one of their users got a direct response from Apple Support that this is a “normal behaviour” of camera’s which are being shipped in smartphones nowadays. Now, Apple has publicly posted a supported document which clearly indicates that this problem can be resolved by simply — changing your position.
Here’s what the document states:
A purplish or other colored flare, haze, or spot is imaged from out-of-scene bright light sources during still image or video capture.
Most small cameras, including those in every generation of iPhone, may exhibit some form of flare at the edge of the frame when capturing an image with out-of-scene light sources. This can happen when a light source is positioned at an angle (usually just outside the field of view) so that it causes a reflection off the surfaces inside the camera module and onto the camera sensor. Moving the camera slightly to change the position at which the bright light is entering the lens, or shielding the lens with your hand, should minimize or eliminate the effect.
It is a long established fact that whenever you point ANY camera lens directly toward sunlight it WILL generate a glare. One MacRumors reader also pointed out this happens with every camera lens regardless of its make.
“This happens with ANY camera!! I have made my living behind the lens for the past 27 years and this happens with every lens!!”
Apple introduced one of the finest camera in iPhone 4S back in October 2011 with their new 5 element lens technology and in iPhone 5 they’ve refined the camera with sapphire lens cover, better image signal processing and noise reduction and still managed to make it thinner than iPhone 4S’ camera.

Intel just in the last week has announced the world’s first silicon based optical data connection that incorporates lasers. Distance is vastly extended over current copper technology as well as allowing greater speeds of 50 gigabits per second. For those who aren’t technically minded, that’s the equivalent of 1 High Definition film being transmitted every second.
While the technology is in its prototype stage, it means in the future we can look forward to less cluttered server rooms as well as faster data transfers between our devices and the computer.

image about whole imaging systemThe Business end of the lens
Accurate focusing is needed doe the very fast lens. At f2.8 the sharp focus zone is about 20/1000 mm! Focusing by hand is a pure Lottery. I have TCF-s focuser and its temperature compensated, so thereis no need to refocus every time when temperature drops.
The focusing system has been build from the scrap metal and some parts found from
Its very easy to move the focuser back and forth between main scope
and the lens.
There is a right size can lid bolted down to a L-shape body.
Focuser is then atattched to the lid.
In a focuser, there is a brass tube. This tube goes back and forth when focuser moves.
Its then rotate the focuser ring of the camera lens. There is peace of fine sandpaper glued
to the tube to prevent slipery, tube has allso a spring load for the same purpose.
I have used TCF-s focuser but it can be any focuser, even manual one!
It will make focusing easier and less random.
The whole project took about three hours of time and cost 50c (I had to buy
The whole assembly is then attached to the dowetail rail at top of the LX200 scope.
This is a second version.
The firs version was made by blywood, but I made it again with metal doe flexsure problems.

CROSS VISION INSTRUCTIONS: In cross eye freeviewing the image for the left eye is on the right and the image for the right eye is on the left. You stare at a point about 1/2 way to the screen so that your eye's gaze is crossing at the half way point. Thus the left eye sees the correct image which is on the right. As you cross your eyes the image will go double. When your eyes are crossed the correct amount the middle images will overlap and be in 3d. The two outer images will remain and will be in 2d.

With research showing as many as one in four school-aged children suffering from vision problems, the Waterloo Lions are doing their part locally to keep up with the club’s national commitment based on a request by Helen Keller in the 1920’s to be “knights of the blind in the crusade against darkness.”
Thanks to a $500 donation by the Waterloo Lions, along with other similar contributions from other area clubs, the Lions Club Regional Eye Care Committee recently purchased new PediaVision screening equipment, which is a digital camera and computer in one device.
The device uses an infrared camera to take digital photographs of children’s eyes from just more than one yard away. The photograph is then analyzed by the corresponding computer system, and “pass” or “refer” results can be printed and given to the child’s parent.
For the Waterloo Lions Club’s support of this new device, regional eye care committee administrator Stanley Schmidt of Okawville brought the PediVision device to Zahnow Elementary last Tuesday, providing free vision screening for young students.
The PediaVision screening equipment can identify the six most common vision issues associated with school-age children, including nearsightedness, unequal pupil size, blurred vision and farsightedness.
“These are things most people can’t notice without a machine,” Schmidt said. “If detected very early, most of these problems can be cured.”
Already, Schmidt said the PediaVision device was able to detect a little girl in the area with an eye tumor.
“We want to put our efforts to youngsters and help them early,” he said.

Bioptics and Driving
Over the past 40 years, bioptics have in part allowed thousands of Americans, whose vision falls below the standard legal visual acuity limits (20/40-20/60), to drive an automobile. Persons who benefit from the latter optical devices illustrate visual conditions that reduce resolution or clarity of vision while maintaining peripheral or side vision intact. The latter might include conditions as: albinism, nystagmus, corneal diseases, macular degeneration and others that affect the central macular area of visual functioning; that which is responsible for our detail and color vision abilities.
What is a bioptic?
A bioptic is a combination two-lens optical system with a telescope(s) attached to a pair of glasses, above one’s normal line of sight (see sample bioptic lens system below). These devices are prescription in nature and available through an optometrist or ophthalmologist who practices clinical low vision. These optical low vision aids are available in a number of different styles, sizes and powers. The most common telescopic units used for driving purposes range from 2.0X - 5.5X (“X” referring to the strength or power of magnification of the telescopic lens unit).
The photo in Figure 1 reveals a frontal view of an older yet still widely used Designs For Vision (DVI), Inc. (Ronkonkoma, NY) 2.2X Galilean BIO II bioptic telescopic lens system in a standard black yeoman frame (note the physical location of the telescopic units, which are above the normal viewing area through the carrier or support lenses).
How are bioptics used during the driving task?
Persons using bioptic lens systems look through the larger or standard carrier lenses for general driving purposes 90-95 percent of the total driving time; and dip down into the miniature telescopic lens unit(s) briefly and intermittently using a simple synchronized head and eye vertical drop technique to discern detail, color or activity as illustrated below.

Photo No.3: A lateral view of a person looking through the telescopic portion ofa Designs For Vision, Inc. (DVI) 2.2X Galilean BIO II mock-up bioptic telescopic lens system (in new brown titanium frame), Ronkonkoma, NY
What benefits are derived from the use of a bioptic lens system?
Once trained in its proper and appropriate use, a low vision driver using a bioptic lens system is able to detect and identify detail, color, and/or movement of critical objects or forms at more normal distant viewing positions during the driving task.
In driver education circles, critical objects or conditions are often defined as any object or condition that which can be predicted to influence or require drivers to adjust their vehicle’s speed and/or lane position. Examples of the latter include: roadway characteristics, other road users and traffic control devices. As a result bioptic drivers increase their margin of safety from such objects or conditions that are present within, along side of, or approaching their intended path of travel.
How many States recognize the use of bioptics for driving?
Thirty nine (39) States currently allow the use of bioptic lens systems for visual assistance in the driving task. Approximately half of those States now offer some type of formalized low vision driving services, with a minimum of 20-30 hours of behind-the wheel instruction recommended or required for novice driving candidates. Ideally the use of more than one instructor is recommended for this subgroup of potential drivers; for example the use of a certified orientation and mobility specialist (COMS) for determination of pre-driver readiness, basic distance viewing skills including bioptic utilization skills, critical objects awareness skills, and a certified driver rehabilitation specialist (CDRS) for all classroom and behind-the-wheel evaluation and training.
What are some of the common misconceptions about bioptic driving?
A few of the common misconceptions about bioptic driving are as follows:
Misconception: Low vision drivers need bioptic lens systems to “see”.
In reality low vision drivers can “see” at varying distances, but not as distinctly as a person with 20/20 distance visual acuity. Engaging telescopic magnification as needed provides sure acuity or clarity of vision. Likewise, all motor vehicle operators drive with reduced visual acuity using our para central and peripheral fields of view approximately 90-95 per cent of the total driving time.
Misconception: Bioptic drivers view continuously v. intermittently through the telescopic portion of their bioptic lens system making the device unsafe for driving.
In reality, trained users glance briefly in and out of the telescopic portion of their device as the need for enhanced acuity arises. Vertex distance, the linear distance between the center of the cornea or clear front window of the eye and the center of the ocular lens of the telescopic lens unit allows the bioptic user to maintain gross awareness of their constantly changing environment while driving.
Misconception: Low vision drivers need not use bioptics in familiar outdoor environments.
In reality we have no control over anything that takes place outside of one’s vehicle. A high state of alertness is needed by all drivers, including those who are visually challenged.
Misconception: Extensive training with the bioptic is needed if it is to be integrated successfully into the driving task.
In reality, greater emphasis initially with young novice drivers should be placed on the development of effective distance viewing skills (including but not limited to: eye lead time or distance, head and eye scanning and following distance), critical object awareness skills (big to small) and hazard perception skills. What is important to remember is that if a student does not feel comfortable with the big picture of the driving scene, he/she will experience considerable difficulty finding or locating detail within the big picture with or without telescopic magnification.

Are there worrisome effects of blue light on children’s eyesight?
First, a basic explanation of blue light from Joel Kestenbaum, an optometrist with Optix Family Eye Care in Plainview: Light is made up of various wavelengths, and each wavelength is a particular color; the shorter wavelengths are in the blue spectrum and some of them can be harmful.
“Blue light has historically only come from the sun,” Kestenbaum says. But with widespread use of technological devices such as smartphones and tablets, which emit blue light, people have more exposure to those wavelengths, he said. Children are especially vulnerable, he said, because their pupils are usually larger and because their shorter arms may cause them to hold devices closer to their eyes.
The fear of some scientists is that the long-term effect might be an increase in macular degeneration and occurrence of the disease at younger ages, Kestenbaum says. “A lot of studies have come out showing the effect of blue light on the retinal tissue,” he says. Macular degeneration causes a loss of central vision — what you see directly in front of you — and has been a disease of the post-65-year-old population. “What scientists believe is that macular degeneration is going to be a disease of people in their 40s,” he says.
In addition to limiting children’s screen time, Kestenbaum suggests setting devices to “nighttime” mode at all times to reduce blue light exposure. If a child wears glasses, parents should consult their eye doctor about whether they should add a filter that blocks a degree of blue light, he advises. If a child doesn’t wear glasses, parents might consider nonprescription lenses with a blue light filter for use when a child is doing homework on a tablet or using a smartphone or computer at home, Kestenbaum says.


Razer has introduced an innovative 4G Dual Sensor System for mice which promises greater tracking precision via a combined optical and laser sensor. According to the company, the new sensor will find its way to Singapore in two of Razer’s mice next month.
Besides the ability to track mouse movements more rapidly and accurately, the new 4G Dual Sensor System also allows customisation of the cut-off height for tracking to stop when the mouse is lifted from the surface. This directly addresses a common bugbear of low mouse sensitivity settings FPS gamers who often pick up their mice to perform multiple wide swiping motions.
The new sensors will find their way into new revisions of Razer’s Imperator wired mouse and Mamba wireless mouse and will be available in Singapore from July for S$129.90 and S$199.90 respectively – the same price as the older revisions.
Here the images of the new mice:
My own take? Pardon the cliché, but this is game changing.
Among more serious gamers, particularly those who primarily play FPS games, it is common knowledge that optical mice are actually better for gaming than laser mice.
This is because optical sensors are better than laser sensors at tracking speed and motion. In laymen’s terms, this allows optical mice to capture 100% of its velocity across surfaces as compared to laser mice, which actually skip, stutter or even drop tracking completely if you’re moving your mouse at high speeds.
Laser mice have their advantages, of course. They have better tracking resolution than optical sensors – giving them greater sensitivity at the highest DPI settings and allowing laser mice to be used on all sorts of surfaces, such as glass and other shiny surfaces, which would normally confuse optical mice.
A mouse that has both the sensitivity and surface tracking ability of a laser sensor and the motion tracking ability of an optical sensor? Sign me up!


The Wellman Center for Photomedicine at Massachusetts General Hospital is the world’s largest academic research facility dedicated to investigating the effects of light on human biology and to the development of light-mediated, minimally invasive diagnostic and therapeutic technologies.
The Wellman Center is a pioneer in light-based biomedical research and has been the source of many popular clinical innovations, so we decided to share a few fun facts. Here are five things to know:
How can light impact health?
Light can affect human biochemistry, in ways that can be both good and bad for our health. For example, ultraviolet light is known to cause the most common human cancer, but it also has mysterious benefits for wound healing, pain, stroke, and blood flow.
What kind of inventions have come out of the Wellman?
Wellman Center researchers have invented a number of popular laser technologies that have been adopted into clinical care. Some technologies include: laser hair removal, tattoo removal, tissue healing (scars, wrinkles and skin pigmentation) and the technology behind CoolSculpting.
Who is the Director of the Wellman Center?
The director of the Wellman Center is Rox Anderson, MD, a world-leading Mass General dermatologist and a Harvard professor. Dr. Anderson has been awarded over 60 national and international patents, and has co-authored over 250 scientific books and papers.
Bill Gates called a Wellman invention one of 10 breakthrough technologies of 2019
In February of this past year, Bill Gates included the “gut probe in a pill” on his list of 10 breakthrough technologies for the MIT Technology Review. The gut probe was developed by Wellman Center researcher Gary Tearney, MD, PhD, and was designed to easily capture images of the gut without the need for anesthesia. Dr. Tearney is a Remondi Family Endowed MGH Research Institute Chair and a Mike and Sue Hazard Family MGH Research Scholar 2012-2017.
What kind of technologies are researchers working on right now?
Wellman Center researchers are constantly looking to improve the efficacy and safety of laser technology. They are currently developing new laser treatments for tissue renewal across organs and working on integrating laser treatment and imaging technology to reimagine surgery. For more information on their current research, check out their website and clinical studies.

The laser will be comprised of more or less cheap and easy sourceable components. This is an important requirement in order to make this development available to the maker community.
The only possible issue are the optics for the resonator. There are suggestions (see Sam’s FAQ) to use polished pieces of copper as a mirror and to drill a hole into the copper as an output coupler. However, using such approach it seems difficult to achieve high power outputs, as desired by the laser. Thus, specialized mirrors and output couplers need to be purchased.
A cheap (and in my research, the only) option is to rely on an import from China. On Ebay there some companies offering CO2 laser optics. It is important to look for resonator optics, i.e. output couplers and concave mirrors.
Thus, the discussion of the resonator design follows the available resonator optics.
- output couplers: On Ebay, there seems to be two different kind of material output coupler: germanium (Ge) or zinc selenite (ZnSe). Both materials are coated to obtain the offered reflectivity of about 70%. The output couplers are plane. One advantage of ZnSe compared to Ge is its transparency in the visible. A laser pointer can be used to align the resonator.
- mirrors: On Ebay available mirrors are concave with an curvature radius varying from 2m up to 10m. The substrate is silicon or glass, that is coated by gold or/and additionally dielectric coating. One should prefer to use the silicon mirrors for higher power application. Since, the coatings achieve no 100% reflectivity and, hence, some of the laser power is transmitted to the substrate. Glass absorbs at wavelength of 10.6 um and the glass mirrors may be damaged.The requirements on the curvature are discussed below.
The resonator geometry is spherical-plane, as dictated by the available components. Then, the resonator needs to be stable, in order for a laser mode to form within the laser. If the resonator is unstable, the losses within the laser might be to large and no lasing is achieved.
In order to obtain a stable spherical-plane resonator, the distance L between the mirror and the output couple has to smaller than the curvature radius R of the mirror, i.e. L<R.
This requirement is easily meet for our 50 cm long glass tubes separating the mirror and output couplers. A mirror with R=2m would form a stable resonator. But, what are the advantages, if there are any, by choosing larger radii?
The crucial parameter to be considered is the beam radius. It is important to note that the laser beam is by no means cylindrical. The beam diameter varies within the resonator and outside, as shown in the following figure. The beam is indicated in red and the outputcoupler and mirror in blue. In this case, the laser would propagate to the left.
Furthermore, the intensity of the beam is the highest at its centre and drops exponentially off to its sides. (At leased, this is the case for the simplest mode, the fundamental mode.)
The calculation of the mode properties are done in Mathematica (see pdf ). The pdf contains all formulas and references to literature. Some of the possible configurations that are possible with the available components are highlighted below. (left blue line: output coupler, right blue line: curved mirror with radius R, thick red lines: beam contour containing 86% of the laser power, thin red lines: beam contour containing 98% of the laser power, dotted lines: beam diameter on mirrors, dash-dotted line: inner bore diameter of discharge tube)
- L=0.5m, R=2m
- L=1m, R=2m
- L=0.5m, R=5m
- L=1m, R=5m
There is a trade-off between beam divergence, beam diameter, discharge volume and diffraction losses. For instance, in the case of L=0.5m, R=2m, the mode is well contained within the discharge tube. The diffraction loss will be small. However, the gas discharge volume is larger than the mode volume. Thus the gain is not optimum.
The other extreme is the case L=1m, R=5m. The 98% contour line does not fit in the discharge tube, thus the diffraction losses are larger than 2%. This limits the output power of the laser, as well.
We will use a ZnSe outputcoupler (70% reflectance) and a dielectric coated silicon substrate mirror with an radius of R=2m.

Cell lens that show details
The Easy-Macro lens lets you take detailed closeup photos with your cameraphone. Unlike other macro lenses, Easy-Macro fits any model phone, with or without a case and stores in your wallet so you will always have it with you. There’s nothing to stick on your phone and no spare parts to lose. The Macro lens sports a 4X magnification while keeping your image as crystal clear as ever. By Easy Macro
A thin rubber band fitted with a macro lens. Slide the band around your phone, line up the lens over your camera’s lens, and you’re ready to shoot. After you attached the lence band, you can still put it in your pocket, not like other lens that is so bulky to fit in. If you’re an iPhone nerd, you definitely need this.
Author Suggestion: Recently In may, A report on Science Daily said the researchers created an optical lens that can be fitted into a smartphone, and magnify images by a magnitude of 120. It only costs 3 cents to produce. This could be easily attached to the lens band we are talking about here. I can’t wait until that bad ass come out. Very excited.

Optical Investigation of the Structure and Function of Normal and Diseased Visual Systems
Research interests include the development and use of novel non-invasive optical techniques for imaging the eye, the use of optical imaging and testing to better understand visual function and performance, image processing, applications of clinical imaging and ophthalmic instrumentation, and understanding the optical limits of human vision and visual performance.
Tracking Scanning Light Ophthalmoscopy (TSLO): The TSLO was developed at UC Berkeley and is a research-grade optical imaging instrument that allows researchers and clinicians to have real-time visualization of retinal structures with simultaneous, targeted visual stimulus delivery. In the clinical setting at Midwestern University, this instrument will be a resource to clinicians and researchers attempting to advance our understanding of normal and diseased retinas as well as the role that eye motion plays in our ability to perform visual tasks. Preliminary research in collaboration with the Roorda Lab at UC Berkeley has shown that it is possible to measure contrast thresholds under stabilized and manipulated eye motion conditions on the TSLO. Expanding these experiments has the potential to provide insight into the optimal retinal motion conditions, in particular with eccentric fixation. The combination of high-quality retinal images and the ability to perform functional, targeted visual tasks will add significant value to standard clinical images and tests currently available.
Visual Performance and Ocular Aberrations with Different Visual Corrections: Corneal and ocular aberrations can be used to quantify imperfections in the eye's optical system in comparison to an ideal, perfectly focused visual system. The use of wavefront analysis and decomposition in the clinic allows this characterization both for the cornea (the front surface of the eye) and the eye as a whole. Current research projects are investigating the role of natural corneal and ocular aberrations in determining daily soft contact lens preference and visual performance and the changes in corneal and ocular aberrations and visual performance associated with scleral (large diameter) contact lens wear in normal subjects.

Exideal uses the 120 of 4 wavelength LED.
This light delivers beauty to your skin.
LED (Light‐Emitting Diode)?
The LED has many practical applications and contributes to solving many problems. It gets attention from health and beauty businesses.
Nowadays, many of them use it as the most advanced technology. One of the main advantages of this beauty treatment is that it is gentle on the skin, painless, and has no side-effects. FDA (Food and Drug Administration) deemed it safe for use on the human body.
This is light humambeing cannot do without.
Some light can cause a bad effect on the human body, but LED utilizes specific wavelengths that are able to illuminate. For example, the sun contains ultraviolet rays that can cause skin trouble.
But LED does not contain any ultraviolet rays and utilizes specific wavelengths that illuminate the skin.
Moreover, Exideal LED makes a strict selection and use of ultra-high luminescent light and ultra-high power for beauty treatment.
Exideal uses a 4 wavelength LED
Blue LED: Wavelength 460mm
Yellow LED: Wavelength 590mm
Red LED: Wavelength 640mm

There have recently been more LED machines at beauty exhibitions. It successively provides LED irradiation for skin treatment at beauty salons.
The photo-treatment, which is the most advanced technology and safe, is popular at beauty clinics in the United States.
LED is very safe.
Demand in the beauty scene is expected to continue.
About harmful effects of the blue light on vision and safety for Exideal
1. Blue color luminous transmittance (permeability) and the opacity of closed eyes
The LED equipped with Exideal is different from the white LED used by most lighting equipment and backup light. It combines with infrared radiation and the specific wavelength colors of red, yellow, and blue.
Each specific wavelength is designed for combining with different types of wavelength(color).
The luminous transmittance (permeability) is very important for care-support programs. The transmittance (permeability) of the LED luminescent color for eyelid and skin are closely related.
The order of red-color and blue-color successfully increases infrared light, but blue light hardly transmits through the eyelid.
According to the paper of luminous transmittance by California University (Moseley MJ [Light transmission through the human eyelid: in vivo measurement.]Ophthalmic Physiol Opt. 1988;8(2):229-30.), eyelid permeability is blue-color 0.3%, green-color 0.3%, red-color 5.6%.
In brief, the luminous transmittance of blue light is 19 times more than that of red light.
Closing your eyes prevents up to 99.7% of blue-color light.(*See Figure 1)
* The LED equipped with Exideal uses a safe power-output, and it is all wide angle dispersed light which includes an infrared light. (It is distinct from laser light and condensed lense light.) The irradiation program is not programmed soley for "blue color" wavelength.
It is programmed to cause contraction of the pupil when feeling the glare. It is considered to have a healthy vision design.
2. About Exideal exclusive goggles and blue color luminous transmittance
The Exideal exclusive goggle accessory is attenuated 460mm LED blue-color capable of 1/166 and it excludes blue-light 99.4%.(Figure 2)
3. Safe to use with Exideal

Infrared light or infrared radiation is a light source that humans can’t see. However, you can sense the high temperatures of infrared light. When in daylight, you expose the human eye to short wavelengths of infrared radiation. In the home, there are many devices that utilize infrared light to operate electronics.
So how can this invisible light affect your eyesight? Can it damage your eyes or is it harmless? Continue reading to find out what infrared light is, what it’s commonly used for, and how it can affect your eyesight.
What is Infrared Light Or Thermometer?
Infrared light is a type of electromagnetic radiation at wavelengths between 780nm and 1000µm. There are three different spectrums that divide light:
- Near infrared (NIR) with wavelengths of 0.78~3.0µm
- Mid infrared (MIR) with wavelengths of 3.0~50.0µm
- Far infrared (FIR) with wavelengths of 50.0~1000µm
Atoms are absorbed and subsequently release energy causing the effects of infrared light. Electromagnetic radiation will include the following from highest to lowest frequencies:
- Gamma rays
- UV radiation
- Visible light
- Infrared radiation
- Radio waves
All of these types of radiation frequencies make up the electromagnetic band.
The wavelengths of infrared light and infrared thermometer are longer than visible light and that’s why humans can’t see it. As mentioned before we can feel the heat of infrared light. Additionally, all objects emit some form of infrared radiation. The human body emits infrared as well as animals, electronics, fire, and the sun.
The Use of Infrared Light
Since the discovery of infrared light in 1800 by William Herschel, innovators have designed an array of devices for residential, commercial, and industrial applications, using this type of light. In this section, we’ll discuss what infrared is commonly used for.
In the Home
There are many items in the home that use infrared to operate. Luckily, these items emit low-range infrared so they won’t have a negative effect on your eyesight.
An infrared light inside a remote carries a signal from the remote to a device it controls to operate it. Remotes change channels on TVs, operate light switches, turn on AC systems, and prompt gate motors.
Incandescent Light Bulbs
Incandescent light bulbs emit 95% of their electrical energy as infrared light.
An infrared lamp heats up bathrooms, saunas and there are types that warm plates & cups. Furthermore, these lamps heat up tanks for reptile pets such as bearded dragons and snakes.
On the Job
Since infrared wavelengths are invisible to the human eye, there are devices such as infrared cameras that assist plumbers and electricians to locate pipes & wires. Hunters use infrared optics to see animals behind thick bushes and firefighters use the devices to locate people in buildings.
The Effects of Infrared Lights on the Eyes
Infrared light in high concentrations and intensity can have a negative effect on the eyes. The development of new technologies brought about stronger sources of infrared light. High exposure to infrared light can cause eye damage, such as retinal burns from welding.
Exposure to infrared light has been connected to many eye injuries caused mainly by the thermal effects of the light. The wavelengths associated with these injuries range between 780nm and 1400nm.
Note that incandescent bulbs and infrared lamps aren’t powerful enough to cause extreme damage to the eyes. However, you should never stare directly into any light source, such as the sun or bulbs, for long periods of time because it can cause irreversible damage to the retina.
When you stare at a light source, the ultraviolet rays can harm the tissue of parts of the eye, like the retina. This is what happens when you stare directly at the sun and the short-term damage is called solar keratitis. Symptoms of solar keratitis include pain, inflammation, and light sensitivity.
High-intensity damage caused by infrared light is called solar retinotopy which is the result of UV light burning holes in the retina part of the eye. It causes central blind spots known as a scotoma.
Infrared Light Therapy
Intense infrared light can damage the eyes but studies show that the use of it can reverse the effects of light damage to the retina. A treatment called red light therapy heals skin and muscle tissue. The red light distributes low levels of near-infrared light.
This type of therapy is also known as low-level laser therapy (LLLT), photobiomodulation, and low-power laser therapy. Studies show that it’s safe for the eyes and has the potential to protect your vision. Red light therapy increases the healing process of people who have inflammation or damaged eyes. Read details
Red Light Therapy Explained
Natural light stimulates mitochondria in your cells which increases the production of Adenosine 5-triphosphate (ATP). ATP is the molecule responsible for storing and transferring energy in cells. Red light therapy fights against macular degeneration which optimizes the cells inside your eyes, even as you age. Therefore, high-quality red light therapy devices can deliver safe wavelengths of natural light to increase cellular energy production.
These devices have integrated medical LEDs that shine natural red and near-infrared light onto your body. This acts similar to the wavelengths produced by the sun but without the UV rays and heat. This is an example of how the benefits of infrared light can be harnessed to serve a great purpose.
To clarify, in order to perform red light therapy, people stand in front of a red lamp between six and 15 minutes a day. This will give the mitochondria in the cells the natural light they need to accelerate the energy that powers your body.
To sum up, high-intensity infrared exposure can damage the eyes and cause loss of vision. But low near-infrared light can assist with healing the body and the eyes. There have been studies in the past that state that near-infrared light can stop further damage to retinal cells and prevent blindness. It’s all about how you use this valuable resource.


How to choose web camera? What are the small details to pay attention to?
Nowadays, broadband networks have been generally popularized, video and voice chat has gradually become a trend, and web cameras have entered our lives.
The web camera not only serves as our video tool, but also plays a role in monitoring security.
We all know that when choosing a web camera, we should choose smart, detectable, alarm, and dialogue… But there are still some small details that will be overlooked. Today we will talk about these issues.
1.The choice of resolution
Many people think that the higher the resolution, the better. In fact, it is not. The resolution is also related to the network transmission speed. The smart web cameras on the market are generally around 2 million. It is no problem to run with 2.4G WiFi, but If you go to 4 million resolution, you need a faster network transmission speed to run. The 4 million resolution camera is best to be used with a 5GHZ network, otherwise, the picture will be stuck and delayed.Therefore, when choosing a web camera, don’t blindly choose a high-resolution web camera. You should make a choice based on network support.
2.Selection of lens material
Nowadays, web camera lenses are made of glass and plastic. Plastic lenses are very cheap, but the imaging effect is obviously inferior to glass. Higher-quality cameras all use 4-layer glass cameras (4G for short). The quality, price, and imaging effects of 4G glass lenses differ greatly. How should I distinguish them? To put it simply, it can be identified by the amount of light passing through the glass lens. The more light that the lens passes through the lens at the same time, the more saturated the imaging color, the better the lens, so when choosing a lens, the better the light flux is.
In general, when buying a web camera, you should pay more attention to some points that are easy to overlook, and choose the right web camera according to your own needs.


Cutting Edge Lens Technologies
Groundbreaking production & lens design technologies from Shamir Shamir’s cutting edge technologies match the lenses not only to the wearer’s prescription and chosen frame, but also to the activity they’re engaged in and even their posture and reading position.
Our lenses incorporate leading edge technologies such as:
Direct Lens Technology™
This cutting edge, Freeform technology is the most advanced system for customized back surface optics. Combining lens design with patient data, results in personalized progressive and SV lenses with expanded vision zones, precision optical power and an elegant lens shape. Direct Lens Technology revolutionizes prescription eyewear, creating lenses with all the right dimensions and optical properties to suit any frame.
Eye-Point Technology® III
Eye-Point Technology III is a new analysis technology that enables Shamir to overcome the problem of different prescription-related viewing experiences. By simulating the real world view for any given prescription, Shamir is able to redefine the viewing experience, ensure similar fields of view for both hyperopicand myopic wearers, and provide an improved viewing experience for all, regardless of prescription.
This technology controls the power profile along the eye’s visual path through the progressive lens corridor, and allows Shamir lens designers to give variable emphasis to the power for every given point on the lens. Based on thistechnology, Shamir has the ability to design lenses optimally suited to a particular activity, from lenses for specific sports, to multi-purpose lenses that pay special attention to clear vision for today’s intermediate visual tasks. This is achievedwithout compromising distance vision, ease of adaptation, or smooth transition between viewing fields.
Natural Posture is a new ergonomic design concept that dynamically locates the near viewing zone within the progressive lens corridor, taking into account the positive or negative power of the prescription. This minimizes the need to tilt the head forward or back, or raise and lower a book in an attempt to bring the text into focus. Any postural discomfort while reading is thereby minimized, ensuring the patient enjoys natural, comfortable viewing posture.
This technology bridges the geometric gap between the trial frame used in the optometrist’s office, and the actual frame chosen by the patient. It ensures that the patient’s experience of the prescription once the lens is fit into the frame, is exactly the same as when originally measured by the optometrist, giving the patient the same viewing comfort and visual acuity.
