Refraction of Light: Laws, Functions, and Example
Refraction of Light: Laws, Functions, and Example: Refraction is the bending of a wave when it passes from one medium to a different. The bending is prompted as a result of variations in density between the 2 substances. Refraction of sunshine is among the most noticed phenomena, however different waves like sound waves and water waves additionally expertise refraction. Refraction makes it attainable for us to have optical devices equivalent to magnifying glasses, lenses, and prisms. It is usually due to the refraction of light that we’re capable of focus light on our retina.
Refraction of light in water: When light travels from air into water, it slows down, inflicting it to vary path barely. This transformation of the path known as refraction. When light enters an extra dense substance (increased refractive index), it ‘bends’ extra in direction of the traditional line. The quantity of bending is determined by two issues: Change in pace, and Angle of the incident ray.
Laws of Refraction of Light
Laws of refraction state that:
- The incident ray refracted ray, and the traditional to the interface of two media on the level of incidence all lie on the identical airplane.
- The ratio of the sine of the angle of incidence to the sine of the angle of refraction is continuing. That is often known as Snell’s law of refraction.
Refraction has many functions in optics and expertise. A number of the outstanding functions are listed under:
- A lens makes use of refraction to type a picture of an object for varied functions, equivalent to magnification.
- Spectacles are worn by folks with faulty imaginative and prescient use the precept of refraction.
- Refraction is utilized in peepholes of home doorways, cameras, film projectors, and telescopes.
An example of refraction of light.
An example of refraction is the rainbow. The light rays bend as they enter water drops within the environment forming a rainbow.
Snell’s law could be derived from Fermat’s precept, which states that the light travels the trail which takes the least time. By taking the by-product of the optical path size, the stationary level is discovered giving the trail taken by the light.


The OrCam device is a smart camera that sits on the user’s glasses and reads text aloud to people who are visually impaired or blind.
While the OrCam device is not exactly “glasses for blind person”, it definitely looks that way. The device is so small and discreet, it is barely noticeable. Besides its compact size, there are many amazing OrCam features that make the device unique and accessible.
Easy to Use
OrCam MyEye is an intuitive wearable device with a smart camera that clips onto a regular pair of glasses and is able to 'read' text and convert it into speech relaying the message to the user. The device is activated by a simple intuitive gesture – pointing your finger or pressing a single button. Using OCR - optical character reading - technology, the device can read printed materials on almost any surface such as newspapers, books, computer screens, menus and more.
Many people who are visually impaired or blind have to carry around a heavy magnifying glass to read text. The OrCam MyEye is small and light and simply attaches to the right side of the user’s glasses frame. The camera weighs ¾ of an ounce and has a thin wire, easily hidden behind the ear, which connects to the base unit or “brain” of the device. The base unit is about the size of a cellphone and can easily sit in one’s pocket or on a belt strap.
“You are what you wear.” Wearable technologies have grown tremendously in the past few years. Smart electronic devices that can be worn on the body are practical and discreet. The OrCam is no exception. Although they are not exactly glasses for the blind person, the device sits on the individual’s glasses frame and is so discreet that it can barely be seen by others allowing the user to fit in with the crowd.
Unlike other OCR technologies, the OrCam does not require a scanner connected to a computer or internet connection. All the information stored in the device is private and only accessible to the user.
For people who are visually impaired or blind and have conditions that cannot be corrected by glasses or surgery, the OrCam MyEye can be life-changing.
Who would have thought that this little camera situated on a pair of glasses could help people who are blind or visually impaired regain their independence?


Eye Surgical treatment has come to be a mainstream method of vision correction, and this article will certainly discuss the advantages and negative aspects of three different methods being provided to the clinical customer.
Lasik Eye Surgical treatment
LASIK is the acronym for Laser-Assisted Sitting Keratomileusis and also is an eye surgical system which completely corrects vision by eliminating a slim layer of the cornea. This treatment functions best on people with moderate to high degrees of nearsightedness (nearsightedness), reduced to modest levels of hyperopia (farsightedness) and also astigmatism related to nearsightedness, and who have thick corneas. It is the most popular medical vision improvement approach.
People with typical eye view see things plainly due to the fact that images are brought right into an appropriate centerpiece by the cornea and also lens of the eye. Ideally, the cornea's curvature is evenly matched to its length in a normal eye. People with astigmatism, nearsightedness or hyperopia have actually off-and-on shaped corneas, so the items seen are not concentrated properly. LASIK adjustments corneal form by exact removal of corneal tissue, and by doing so deals with the eyes' focusing power.
There are, however, threats to LASIK eye surgical procedure.
There is a remote possibility of complete loss of vision. If this takes place, it is normally because the patient had a pre-existing problem which ought to have averted the surgical treatment in the first place, such as maternity, cataracts, arthritis, diabetes mellitus, glaucoma, or lupus. People with large students are also inadequate prospects for LASIK. Dry eye syndrome will certainly be aggravated by this treatment.
A few individuals whine that they permanently see "ghost" photos, have blurred vision, lessened contrast as well as negative night vision. When LASIK wased initially presented, 5% of clients had post-operative issues; however, refinements in the treatment have actually caused this rate to go down to much less than 1% if LASIK is done by proficient professionals and also clients are appropriately evaluated prior to surgical treatment. If issues do take place, they can commonly be resoved by a retreatment.
FDA has actually accepted LASIK laser eye surgery considering that 1998. While there are a great deal of completely satisfied patients, there are however no long term research studies regarding its impacts. Understand the constraints and also the dangers of LASIK eye surgical procedure prior to you sigh up for the procedure.
Though less well known, these small implants can improve vision in patients with mild to modest nearsightedness without the danger of long-term eye damage fundamental in the tissue elimination strategy of LASIK. Intacs are semi-circular disks dental implanted in the cornea which extend it to assume a flatter shape. Though a little much less accurate than LASIK, they are removeable and also changeable, so if the client has an unexpected over- or under-correction, the implant could be eliminated and an additional of a various size put to acquire the desired correction. The implants lie beside the cornea, so the central aesthetic area is completely undamaged and intact, and the strength of the cornea is undiminished, making it a far better choice for pilots and those that participate in contact sporting activities where eye injury is an Learn More opportunity.
Intacs disagree for severe nearsightedness and greater than minor astigmatism (1.00 diopters), as the cornea could just be extended up until now. If the Intacs are gotten rid of, vision returns to its preoperative degree. Besides vision correction, Intacs are additionally used to deal with keratoconus.
Intacs are FDA approved and also 10 year researches have actually disclosed no major issues with Intacs and also few person complaints; nonetheless, since the procedure takes a lot more training than LASIK, there are fewer eye surgical treatment clinics providing it. However, the Intacs site provides a listing of specialists in each state, too a couple of in Canada, Europe and Mexico.
Since many individuals do not intend to risk LASIK and Intacs can not assist Visit Website those with serious vision troubles, intraocular lens implants (IOL) are a brand-new alternative accepted by the FDA in 2004 to deal with moderate to extreme nearsightedness. The Craftsmen lens, made by Ophtec, resembles the sort of lens dental implant used to bring back vision complying with cataract eye surgical treatment.
The new IOL, called the Artisan, is meant for only patients that have 2.5 diopters or much less of astigmatism.
The fabricated lens does not change the all-natural lens, however is placed in front of it. The main trouble discovered with the dental implant was the consistent loss of endothelial cells in the corneas of individuals who received the implants. The endothelium is a layer of cells that line the undersurface of the cornea and also are important in maintaining the cornea clear. A three-year research revealed a constant constant loss of endothelial cells of 1.8 percent a year. At this moment, nobody can forecast whether this loss will certainly proceed at the same price indefinitely, or perhaps its influence on corneal feature.
To reduce long-term results of the gadget on the corneal endothelium, the FDA is requiring that the brand-new lenses be identified to define that they must only be dental implanted in clients whose corneal endothelial cells are thick adequate to endure small cell loss.
Much more serious issues were few: retinal detachment (0.6%), cataract growth (0.6%), and corneal swelling (0.4%). The FDA is needing Ophtec to conduct a five-year follow-up survey of its dental implant clients to much better evaluate the post-surgical occurrence of cataract development, retinal detachment and also various other sensory conditions.
The Artisan lens is meant to be a permanent implant.Though it can be eliminated operatively, vision may not always go back to just what it was prior to getting the lens. Since it does not influence astigmatism, patients with this problem may still call for glasses.

In this work, we describe the role of the different layers in perovskite solar cells to achieve reproducible, ~16% efficient perovskite solar cells. We used a planar device architecture with PEDOT:PSS on the bottom, followed by the perovskite layer and an evaporated C60 layer before deposition of the top electrode. No high temperature annealing step is needed, which also allows processing on flexible plastic substrates. Only the optimization of all of these layers leads to highly efficient and reproducible results. In this work, we describe the effects of different processing conditions, especially the influence of the C60 top layer on the device performance.

A laser AE method is non-contact measurement of AE by using laser interferometer sensor. However, the sensitivity of laser interferometer is lower than conventional piezoelectric sensor. In this study, a method to improve signal-to-noise ratio of the output waveform of interferometer is investigated. A new system was developed to record and analyze the waveform continuously. Continuous waveform was transformed into time-frequency-magnitude data by short time Fourier transform (STFT) or wavelet transform. After noise component in this time-frequency-magnitude data is cut, inverse STFT or WT is applied to obtain clear AE signals in time domain. Simulated AE signal generated by thermal stress of YAG laser pulse was analyzed and detection capability of AE event was improved compared to the conventional signal processing method.

SYDNEY: Capturing a billion pixels in a single snapshot could be one step closer to becoming mainstream, with the development of a new prototype gigapixel camera.
A team of U.S. engineers described the camera, called AWARE-2, in a letter in the journal Naturetoday.
Gigapixel imaging captures details covering the entire human visual field at five-times better resolution, meaning the image can later be examined by zooming in without losing clarity.
“With a camera capable of simultaneously focusing on everything, the photographers job becomes looking for the interesting events in the already captured images, rather than predicting the events before they happen,” said David Brady, an optical physicist at Duke University in North Carolina, and co-author of the study.
Device weighs 45kg, costs more than $100k
“With such a photograph, one might say – when observing Sydney Harbour, for example – ‘This is beautiful, but I wish I could examine it in more detail with a photograph.’”
The AWARE-2 optical system consists of a 6cm ball-shaped lens surrounded by an array of 98 micro-cameras, each with a 14-megapixel sensor. The device is housed in a 75cm x 75cm x 50cm box and the optical system and case combined weighs about 45kg. The cost for such a system today would be similar to that of a high-resolution digital movie camera, Brady said – between $100,000 and $250,000.
Gigapixel photography has several uses for science, including observing “dynamic events in the sky, such as meteor showers and asteroids, which cannot be captured in narrow-field telescopes,” said Brady. Other uses include wildlife and environment monitoring over a wide field, or even live-streaming sporting events online: viewers could zoom in and watch the game from whatever perspective and resolution they choose.
A pixel is a small light point in a digital image, concentrations of which together form a picture. Today's cameras capture images measured in megapixels – one million pixels – normally between eight and 40 for an average consumer device. A thousand megapixels or a billion pixels, make a gigapixel.
Already in use today are highly specialised gigapixel astronomical telescopes and airborne surveillance systems, which are comparatively large and have a narrow field of view, said Brady. There are also some film-based gigapixel cameras. Most of today's gigapixel images are made by digitally merging several megapixel pictures.

Choosing A Home Theater Projector that Suits Your Needs
By XGIMI Tech - 2023-12
Introducing New Projector Technology
Lasers and LEDs have become the most popular light sources for home theater projectors because of their many perks. However, while both light sources are exceptional, they have their shortcomings. The most notable problem with using either, which has remained a problem for projector manufacturers, is that they cannot balance image quality with viewing comfort.
XGIMI always tries to bring innovations to the projector industry to offer you the best solution to your home theater needs. The XGIMI HORIZON Ultra solves this age-long problem with its latest technology advancements, the Dual Light technology. XGIMI HORIZON Ultra combines Laser and LED to provide exceptional image quality and comfortable viewing simultaneously. This article delves into home theater projectors and discusses the outstanding features of the HORIZON Ultra.
Laser Home Theater Projector vs. LED Home Theater Projector
Laser home theater projectors don’t use a light bulb to project like other traditional projectors. Instead, it uses laser beams to project images onto a screen or surface. On the other hand, LED home theater projectors are portable projectors that use LED lamps as a light source to project images to a surface. While the main difference lies in their definitions, there are other differences between laser and LED projectors. They include:
|Consistent and accurate color performance over time
|Accurate colors but can decrease over time
|High brightness, suitable for use in bright rooms or outdoor settings
|Lower brightness levels, less ideal for use in bright rooms or outdoor settings
|Longer lifespan than traditional lamps
|Longer lifespan than traditional lamps
|Better contrast and deeper blacks
|Lower contrast ratio
|Generally more expensive
|Generally less expensive
What Should I Look Out for When Buying Home Cinema Projector?
Your home cinema has to be appropriately planned for, which includes looking for the best home movie theater projector. Just any projector won't do. If you want to have that cinematic experience, this is what you should consider:
All projectors come with light sources to illuminate the picture displayed, and it's essential to know how bright a projector is before buying. Brightness directly influences image quality, as low brightness will make the picture appear dim.
However, the right brightness level will display sharp and stunning images. Projector brightness is measured in lumens; the higher the lumen, the brighter the projector. You must consider the screen size and ambient light to find the appropriate lumen for your home cinema. A large screen needs more lumens, while a smaller screen size will require less. Also, ambient light affects brightness, so you will need more lumens for a lit room or when watching during the day than watching at night or in a dark room.
2. Image Quality
Several factors determine image quality, including contrast ratio, brightness, and color accuracy. But the primary one you should look out for is the image resolution. Resolution refers to the number of pixels displayed per inch of an image, horizontally and vertically. These pixels are the smallest unit of an image.
So, typically, the more pixels a projector can display, the higher the resolution, which determines how crisp, clear, and detailed an image will be. The best resolution for home cinema is full HD (1920 x 1080 pixels), true 4K (3840 x 2160 pixels), or 8K resolution (7680 x 4320 pixels). Depending on your budget, you can opt for a full HD or a 4K home theater projector.
3. 3D Compatibility
3D-compatible projectors use specialized technology to reproduce three-dimensional impressions on a two-dimensional surface without distortion. They project two different images for each eye, creating an illusion of depth. The best home cinema projector for an extraordinary cinematic moment is 3D-compatible. With amazing 3D technology, every viewing moment becomes magical as the quality of your content doubles and deepens with the 3D effect.
Another crucial factor to consider is the available input or connection options. These connectivity options enable you to connect other devices to your projector to transfer files. A good home cinema projector should offer several options so you can have a wide variety to choose from. This must include wired options like HDMI, USB, DVI, and VGA and wireless ones like Bluetooth and WiFi. Before buying, always check if the projector is compatible with your device connection option.
You need great speakers for an immersive cinema experience in the comfort of your home, so finding a home theater projector with powerful speakers that produce clear sounds is vital. The built-in speakers should be able to match the quality of an external speaker, delivering loud and clear audio that accentuates your cinematic experience.
Home Theater Projector Recommendation
If you are looking for the best home entertainment projector for immersive cinematic moments, you need not look further than XGIMI’s product list. With a dedication to offering nothing but the best, XGIMI has designed a world-class long-throw projector to meet your home theater needs:
XGIMI HORIZON Ultra：
The new XGIMI HORIZON Ultra is a premier long throw 4K home cinema projector that combines LED and laser light sources to bring you the best. With stellar features like Dolby Vision, the HORIZON Ultra is a top choice for high-quality home entertainment. Below are the exceptional features it offers:

August Photography Trip
Digital photography is a form of photography that uses cameras containing arrays of electronic photodetectors to capture images focused by a lens, as opposed to an exposure on photographic film. The captured images are digitized and stored as a computer file ready for further digital processing, viewing, digital publishing or printing.
Until the advent of such technology, photographs were made by exposing light sensitive photographic film, and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.
In 1981, Sony unveiled the first consumer camera to use a charge-coupled device for imaging, eliminating the need for film: the Sony Mavica. While the Mavica saved images to disk, the images were displayed on television, and the camera was not fully digital. In 1991, Kodak unveiled the DCS 100, the first commercially available digital single lens reflex camera. Although its high cost precluded uses other than photojournalism and professional photography, commercial digital photography was born.

Nikon’s beginnings date back to 1917 in Japan. At first, the company mainly produced lenses - telescopes, binoculars, microscopes and other small, optical equipment. Soon the company expanded its portfolio, producing photographic lenses under the Nikkor brand.
In the field of cameras, particularly among professionals, Nikon quickly gained a reputation as a top manufacturer, which continues today. Its cameras were even included in the equipment of American spacecraft. Nikon designed and produced the legendary Nikon SP 1957, regarded by many as the best camera of all time.

The Canon Rangefinders are full frame 1960s lenses in modern cinema housings. The set is based around the legendary 50mm f/0.95 released in 1961. All the lenses in the set have their original 1960s single-layer coatings that produce beautiful low-contrast images, and golden flares. Despite their age, they are sharp, even wide open, with surprisingly low chromatic aberration, even for vintage, high-speed lenses. They also have a unique painterly bokeh, that gives images a texture and depth you can’t really get with modern lenses.


Bi-directional SFP Transceiver for Fast Ethernet fiber optic cable (Tx: 1550nm, Rx: 1310)Kust osta
The DEM-220T/220R Bidirectional Fast Ethernet SFP Fiber Transceivers are external transceivers designed for insertion in SFP (Small Form-Factor Pluggable) slots of network devices for transmission and reception of data signals on the fiber cables. These transceivers provide the 100BASE-BX operation and physical compactness to deliver the speed, reliable long-distance data transfer, and deployment flexibility that today’s fiber networks require.
Ideal for Long Distance Application
The DEM-220T/220R transceivers can be used to connect together switches, servers and fiber modules on a campus or metropolitan area network (MAN). Providing up to 20 km of fiber cable distance, these highly integrated transceivers offer low jitter performance for extended optical link support without any degradation in performance.
The DEM-220T/220R transceivers combine transmitting and receiving signals onto one fiber strand using two wavelengths. These transceivers are used in pair. At one end, one transceiver uses one wavelength to transmit and a second wavelength to receive. At the other end, the other transceiver flips that relationship.
The DEM-220T/220R transceivers use standard simplex LC connectors for fiber cable connection. They conform to industry standards and are interoperable with certain D-Link switches. Hot-swap capability allows network administrators to plug or unplug them from the SFP slots without having to turn off the power of the connected device.
The DEM-220T/220R transceivers are packed in a Small Form Pluggable (SFP) metal housing to increase durability.

How are LEDs used in Lighting
LEDs are incorporated into bulbs and fixtures for general lighting applications.
Small in size, LEDs provide unique design opportunities.
Some LED bulb solutions may physically resemble familiar light bulbs and better match the appearance of traditional light bulbs.
Some LED light fixtures may have LEDs built in as a permanent light source.
There are also hybrid approaches where a non-traditional “bulb” or replaceable light source format is used and specially designed for a unique fixture.
LEDs offer a tremendous opportunity for innovation in lighting form factors and fit a wider breadth of applications than traditional lighting technologies.
The useful life of LED lighting products is defined differently than that of other light sources, such as incandescent or compact fluorescent lighting (CFL).

The 2018 Nobel Physics Prize has been awarded to Arthur Ashkin, and the other half jointly to Gerard Mourou and Donna Strickland “for their groundbreaking inventions in the field of laser physics.”
American Ashkin of Bell Laboratories in the United States won half of the prize while Frenchman Mourou, who also has U.S. citizenship, and Canadian Strickland shared the other half.
Strickland, of the University of Waterloo, Canada, becomes only the third woman to win a Nobel prize for physics.
“The inventions being honored this year have revolutionized laser physics,” the Royal Swedish Academy of Sciences said on awarding the nine million Swedish crown (USD 1 million) prize.
“Advanced precision instruments are opening up unexplored areas of research and a multitude of industrial and medical applications,” it said in a statement.
Ashkin invented optical “tweezers” that could grab particles, atoms, viruses and other living cells while Mourou and Strickland separately created the shortest and most powerful laser pulses ever.

TONIC SHIMMER RED Mirror GLASS LENS Polarised Polarized Fishing Sunglasses
or 4 payments of $62.25 with Info
Tonic Eyewear Boutique Lenses
Polarisation: With Tonic Eyewear's lenses anglers have polarisation and our custom made light filtration system that delivers unsurpassed clarity and colour enhancement. The Tonic Gen2 range features all new filter systems that now deliver enhanced light transmittance and colour separation.
Crystalite Glass: Tonic is the only fishing sunglass in Australia using Crystalite Glass: the clearest glass lens currently available. Our Gen2 range now features the remarkable SLICELENS. At only 1.3mm and 60% lighter in weight than the industry norm, the SLICE is the thinnest and lightest polarised glass lens every made. So truer than ever, Tonic sunglasses can be worn all day and don’t feel heavy.
Decentration: Tonic makes each lens decentred which is important for viewing true depth and true distance. Decentring eliminates prism or the feeling that you are losing footing when you are walking through streams and over rocks.
Anti-Reflective Coating: Tonic has an anti -reflective coating applied to the back surface of the lens to reduce reflective glare or "bounce back" to the pupil. This is extremely important when sight fishing.
Tonic’s Four Colour Spectrum Filter: Our four colour integrated polarising filter system in the back of the lens: we have green which retains colour, yellow which gives high contrast when ambient light is low, brown and copper mix to give high definition.
Tonic’s Three Spectrum Filter: Our three colour integrated polarising filter system in the back of the lens is a unique feature of our grey lens: we have grey to give a “natural eye” viewing experience, green and aqua which give high definition and vibrant colour absorption.
Clik-Strap: Removable and adjustable safety strap.
Custom Nose Bridge: Adjustable Nose Bridge comes with our RISE, TRAKKER & YOURANIUM styles.
The photochromic copper lens is a high contrast copper bronze. This lens is photochromic so it darkens or lightens depending on ambient light conditions. This lens has been developed to give the highest quality optics in fresh water and salt water conditions. The Photo Copper can be comfortably worn all day in all light conditions.
The Neon lens is the lightest fishing lens on the market in Australia today. It brightens things up like a neon light. It picks up the reds, blues, greens and yellows and has a very broad light spectrum which allows you to see very early in the morning or late in the evening.
The grey glass has three colours integrated into the lens: grey, green and aqua. Where most grey lenses tend to flatten colour out, the Tonic grey lens defines colour. That is a big difference between Tonic and any other grey lens on the market. Just like all the Tonic lenses, the clarity is unbeatable. Our Gen2 Grey is now photochromic, adding even more versatility.
With great clarity and optics our new mirrors look and feel fantastic. With copper based green and grey based red and silver, we have all water types covered. Tonics mirrors offer high definition glare reduction and they deliver high contrast in low light conditions and a very high result when fishing. The mirror itself has been applied inside the lens and so cannot be scratched off.
Tonic’s polycarbonate lens is a great entry level to high quality optics. Extremely lightweight and hardwearing, our polycarbonate lenses are a decentred injected mould lens with anti-reflective coating on the back surface and an anti-scratch coating applied to the front and back surface.
All Tonic Eyewear frames are made from TR90 optical grade material. They are all tough and lightweight. Our frames are designed to be comfortable and optimise block out of sunlight. Any non TR90 components are nickel or stainless steel to prevent rusting. Currently our range features high gloss black, matt black and high gloss tortoise shell designs.

Smartphone for blood pressure detection
Published: 17:34 17 August 2019
Many new features are being added to the smartphone due to the advancement of technology. Many health-related features are also being added. Subsequently, a technology for smartphone ‘Transdermal Optical Imaging’ invented which is able to measure blood pressure.
A research team of the University of Toronto, Canada, said that the technology will measure blood pressure by analyzing short video that contains facial expressions. Through this, 95 percent accurate result can get. A smartphone app is under developing based on technology.
Kang Lee, a Professor and the Research Chair of Developmental Neuroscience of the University of Toronto, is developing the smartphone app that can monitor blood pressure by analyzing a short selfie video.
Digital sensors on a smartphone can detect the red light that’s reflected by hemoglobin, a blood cell protein, under the skin. This allows the camera to capture minuscule changes in circulation that can be used to predict blood pressure through machine-learning algorithms, Lee explains.
Lee and his colleagues measured the blood flow of 1,328 Canadian and Chinese adults by capturing two-minute videos using an iPhone equipped with transdermal optical imaging software.
The technology's high accuracy is within international standards for devices used to measure blood pressure, according to Lee.
“If future studies could confirm this exciting result in hypertensive patients and with video camera measurements made during daily life, then obtaining blood pressure information with a click of a camera may become reality,” according to Ramakrishna Mukkamala, circulation imaging Editorial Author and Professor of Michigan State University.
The videos were captured in a certain light in a controlled environment in the laboratory. However, it is not yet clear how effective this technology will be in the outdoor environment or at home. Besides, the sample used in the test is not enough for this app.

Better than any camera—the eye’s response to light
When you emerge from a darkened room out into bright sunlight, your eye mechanically shrinks the pupil, cutting down the amount of light entering the eye. In fact, the eye works marvellously in a wide variety of light intensities, i.e. from hardly any light to very bright light.
The eye can detect a single photon of light, the faintest light possible. Despite some evolutionists claiming that the eye is badly designed, it is impossible to improve on this sensitivity! But the eye can also work with 10 billion photons; that is, its dynamic range is 10 billion to one.
Modern photographic film has a dynamic range of only about 1,000 to one. Also, one of us (JS) performed doctoral research using state-of-the-art light detectors. However, they were so delicate that they needed protection from more normal light intensities using filters that let in only a millionth of the light; otherwise, the detector would have been destroyed. Newer models have an automatic shut-off. Yet the eye easily adjusts to a far wider range without needing such a shut-off.1
The best known way the eye copes with varying light intensity is the iris. This is the coloured ring of the eye. In bright light, muscles contract and narrow the pupil, letting less light in. In dim light, other muscles widen the pupil.
But the biochemists Craig Montell and Seung-Jae Lee have discovered that microscopic machinery is involved, not just the large-scale motion of the iris. They examined fruit fly eyes, which have similar proteins and light detector cells to ours.
These cells have the light-detecting proteins in one end of the cell. But another protein, called arrestin, is moved around in the cell in response to light.
In dim light, arrestin is in a ‘holding area’. But in bright light, it is shuttled so that it can bind and ‘calm’ the light-detecting protein, thus protecting it.
The arrestin doesn’t just drift into place. Rather, it is moved quickly by a motor protein, myosin, along the ‘train tracks’ of the cell’s internal skeleton. The myosin and arrestin are ‘glued’ together with special sticky fats.2
Dr Montell explains, ‘For the cell to properly adapt to bright light, arrestin needs to move. If it doesn’t, the cell remains as sensitive to light as it was when it was dark.’3
Chance or design?
Far from being a poor design, the eye’s dynamic range exceeds that of the best man-made photodetectors. And this latest research shows the intricate microscopic machinery behind it—a motor, glue, ‘calmer’ and internal ‘train tracks’.
All these features would need to be present and coordinated; otherwise, the eye would be blinded by bright light.4 Thus natural selection could not build this system up step-by-step, since each step by itself has no advantage over the previous step, until all steps are complete.
The Bible has a far more cogent explanation: ‘I am fearfully and wonderfully made’ (Psalm 139:14)—an explanation so obvious ‘that men are without excuse’ (Romans 1:20).

A three-chip DLP projector uses a prism to split light from the lampand each primary color of light is then routed to its own DMD chip, then recombined and routed out through the lens. The number of mirrors corresponds to the resolution of the projected image often half as many mirrors as the advertised resolution due to wobulation. Brief visible separation of the colours can also be apparent when the viewer moves their eyes quickly across the projected image.

Nowadays, polarized sunglasses are gaining popularity among adults. The primary reason behind it is that they look stunning and protect your eyes from harmful rays. You may want to know if the polarized sunglasses you have brought are real or fake. Some companies and brands try to trick the customers into buying fake ones. Now, you don’t have to worry. We will discuss some essential tips on how to check the same. You will effortlessly find the most suitable sunglasses for you after you gain some knowledge regarding the same.
There are many benefits to wearing polarized glasses. You can improve your vision and also decrease eye strain problems. We will take a closer look at other vital benefits later in this article. If you are planning to buy it, you should know everything to make a perfect choice. You will find various websites that provide reliable information about different kinds of eyewear. You can consider occhiali.blog to do complete the task of consuming information. It is one of the best websites to learn about all the popular sunglasses.
Sunglasses can change a person’s overall appearance, according to fashion experts. If you are a fashion lover, you must try wearing glasses to enhance your look. Due to this reason, people are more willing to invest in them for various reasons. They are also beneficial for people who travel a lot because they must protect their eyes from harmful Ultraviolet rays. However, it is only possible when your sunglasses’ lenses are polarized. You might be curious to know how you can identify them. So, let’s dive deeper into the same.
What are polarized glasses?
Polarized sunglasses are designed to provide people with better and clearer vision. Lenses decrease glare by adjusting the contrast, brightness, and color of objects you see in the sun. So, you will be able to obtain high-quality visual effects when using them. These glasses are perfect for protecting your eyes from harmful radiation. If you tend to suffer from eye fatigue, you should use these glasses to prevent it.
How do the lenses work?
The science behind this fantastic ability is complex to understand. But we will try to explain the same straightforwardly. As long as sunlight passes through the reflective surface, it will return horizontally in the same direction. This reflection is harmful to the eyes because it produces a temporary glare.
Polarized lenses can absorb sunlight and block horizontal reflections. They only let vertical reflections pass through them. Therefore, you will not experience a sharp glare. Other lenses are not designed to give this kind of result. They might not be able to keep your eyes safe from it.
Another good thing about polarized lenses is that the brightness, contrast, and color will automatically get balanced while you wear the polarized glasses. Some people struggle with eye fatigue, headaches, and sensitivity to light when wearing any sunglasses. The use of polarized glasses can help eliminate various eye-related issues. As they are available in a variety of options, you can select the right one. Also, don’t forget to research well before deciding on a particular style of sunglasses.
Is there any way to tell if your glasses have polarized lenses?
It might seem like an impossible task to find whether your lenses are polarized or not. However, it is not as you can consider the following methods to find
- Use a computer to test the polarization: You have to use your computer or a laptop for this method. As the screens of these devices act like polarized lenses, they can help find the same. The first step is to put on the glasses and rotate them while you focus on the screen. Now, observe if any part is darkened. Once you discover any dark area, it means that your glasses are original.
- Looking into the water: Another way to test for polarization is to look into the water. Even in the sun, these glasses can see things in the depths of the water. You can go to nearby waters for this test. If you can’t see the fish, the rocks in the lake while wearing them, it proves that your sunglasses have ordinary lenses. But you need to check if the lake is clean or not before proceeding with this method.
- Use two pairs: You can ask your friends for another pair of sunglasses and start testing. For this, you have to face both the pairs towards each other. Then, observe the images through them carefully. Now, rotate one of them about 60 degrees. When you see any difference in the overlapping area, it means you have original polarized lenses.
- Look at the label of the sunglasses: Almost every eyewear has a label of the brand. You need to check the information written on the label. If “Polarized” is mentioned on it, it means you have got polarized eyewear. Sometimes, the brand’s label is not present with the glasses. So, you can consider other techniques for the same.
- Use reflective surfaces: In this method, you need to find a shiny reflective surface. Now, put on your glasses and look at the surface. If your vision is disturbed by reflected light, they are not polarized lenses and vice-versa.
What are the benefits of wearing polarized eyewear?
- A comfortable vision is possible: Polarized sunglasses are comfortable to use in the sun. They provide a clear vision through balanced light, contrast, and color. You can reduce eye-related issues like headaches and sensitivity to light. Many sports players also use them for a clear vision in sunlight.
- Better eye protection: You may already know that UV rays are harmful to your eyes. Unlike standard lenses, its lenses are more potent in absorbing harmful light to protect the retina.
- Helps to obtain visual clarity: You can use only polarized lenses to get optical clarity. With these sunglasses, the brightness, contrast, and color of objects are more balanced.
The Bottom Line
It indeed sounds pretty hard to find whether your sunglasses have polarized lenses or not. Still, there are some effective methods to discover the same. We hope this article helped you in understanding the techniques in detail.


Ceramic exhibition center, Tangshan, China

Frosted glass is usually adopted in natural lighting of an exhibition space, through the frosted glass the visual contrast is greatly reduced and the view of objects behind the glass is blured. In this way the visitors can concentrate on the Exhibits. This design focus on how to “blur” the spacial background in the building. That means to minimize the contrast in the background space.
The profile of this building serves as the background of outdoor exhibition. In order to minimize the visual contrast, the profile of this architecture is designed as a mild curve which naturally rises from the ground, thus the outdoor background is “blured”. At the same time there are more outdoor exhibition areas as is shown in the height level diagram. Edges of walls in the exhibition space and direct light from outside cause contrast in sight. So the “Bluring” of indoor exhibition backgrounds consists of two parts: creating an “edgeless” space and adopting diffuse lighting. A continuous wall with wiping angles wraps the studio units and serves as an edgeless background of indoor exhibits.In order to avoid direct sun light and strong contrast in the sight, all the natural light in the underground gallery comes from above through the skylight and get into the visitors’ eyes after several times of reflection. Frosted glass is adopted in th skylight, changing direct light into diffuse light, providing a mild indoor light enviroment.
