polarized lenses lcd displays in stock

Polarized sunglasses may make it easier and more comfortable to see outdoors, but wearing them while trying to read an LCD (liquid-crystal display) screen can sometimes — literally — leave your eyes in the dark.

Most LCDs, such as your smartphone and tablet, use a polarizing filter to help you see the screen in bright sunlight. But so do polarized sunglasses, meaning the two essentially cancel each other out, causing your LCD screen to appear dark or completely black when you look at it.

Polarized sunglasses are designed to block glare — overly bright light reflected off shiny surfaces such as water and snow. Natural light consists of protons bouncing in many directions; polarized lenses filter that light, causing those protons to travel in a single, uniform direction (usually horizontal).

Polarized sunglass lenses are coated with a chemical compound composed of molecules that are parallel to one another. These molecules absorb any light waves traveling in the direction in which they’re aligned, preventing them from passing through the coating.

LCD screens and sunglasses typically contain a polarizing filter for the same reason: to make it easier for you to see clearly, especially in bright sunlight.

What tends to happen is your polarized sunglasses do their job by only allowing light to pass through vertically. Meanwhile, your phone screen emits horizontally vibrating light while blocking vertical light.

Your lenses and screen end up counteracting each other by working in opposite directions. As a result, you wind up seeing a dark or blacked-out image.

The solution is simple: Rotate your tablet or phone screen by 90 degrees. This trick usually works because it positions your screen’s polarizing filters so they block light waves traveling in the same direction as your polarized sunglasses, allowing light to pass through.

Newer smartphone and computer screens have found ways to compensate for this issue, but you may still notice a darker screen when wearing polarized sunglasses with an older model screen.

In some cases, you may need to view LCDs on an instrument panel that can’t be rotated. This can be true for boaters and pilots who must be able to read instrumentation quickly and accurately to ensure their safety. For this reason, you should avoid wearing polarized sunglasses in these circumstances.

Polarized lenses also can interfere with your ability to see and read the displays on gas pumps and ATMs. To see more clearly when filling your tank or withdrawing money, remove your sunglasses when performing these tasks.

Any reputable eyewear retailer (brick-and-mortar store or online shop) will provide accurate labeling on sunglasses they offer, so you should be able to tell at a glance whether those sunglasses you’re considering have polarized lenses.

Hold the sunglasses in a way that allows you to look through both pairs of lenses at the same time. Rotate one pair of sunglasses by 90 degrees. If all light is blocked when passing through both pairs, then your older sunglasses probably have polarized lenses.

You also can test your sunglasses by looking at an LCD screen while wearing them. Just remember to rotate the device 90 degrees to make sure you’re checking for a polarizing filter that blocks light traveling either horizontally or vertically.

It’s always calming and important for a healthy lifestyle to spend time outside. While soaking in the sun is one thing, protecting your eyes while you’re outside is crucial. You should choose polarized sunglasses if you enjoy being outside. When you’re working outside in a high-glare setting surrounded by water or snow, polarized glasses can assist minimize glare and offer better visibility. However, how does polarized glass function? Let’s first define what “polarized” means.

The sun’s rays disperse in all directions. However, when light hits flat surfaces, it has a tendency to become polarized, which causes the reflected rays to move in a more consistent (often horizontal) direction. This produces a grating, occasionally hazardous intensity of light that can impair sight.

When a lens is polarized, a filter that prevents strong, reflected light is already present in the lens. This intense light is known as glare. Glare reduction makes your eyes more at ease and improves your ability to see your surroundings.

When you’re carrying a pair of grey polarized sunglasses, everything could appear a touch darker than usual. However, the increased protection for your eyes from the sun’s rays and glare is the trade-off and difference from normal sunglasses. On a cloudy day, brown polarized glasses are preferable to grey polarized lenses because they can boost contrast. Darkened polarized lenses are ideal for outdoor activities and situations where there are a lot of glares. They’re not the best for hobbies like reading glasses though.

You now know that the primary factor in polarized lenses’ somewhat higher price is their ability to reduce glare. However, how precisely does this filter perform? Always keep in mind that polarized sunglasses still offer UV protection, but their secondary benefit is the reduction of glare caused by horizontally oriented light.

When sunlight falling from above reflects off these reflective surfaces, it is reoriented and condensed into horizontally aligned light, which causes glare. Polarized sunglasses are advantageous in this situation because they prevent this unwelcome and perhaps dangerous glare from going through your lenses. Non-polarized materials lack a polarizer layer, hence they are unable to carry out this task. So, if you want to protect your eyes from harmful glare, invest in a set of good polarized sunglasses.

By now we all know that glare is annoying and by wearing polarized glasses you can protect your eyes from this unwelcoming guest. According to studies, intersection accidents, which are a leading cause of traffic accidents, happen more frequently when the sun is at its glare-producing peak. You may improve your awareness of your surroundings and possibly prevent accidents and injuries by decreasing glare.

The lenses are designed to provide you with color and clarity in your vision while eliminating color distortion to the greatest extent possible. As a result, you wouldn’t need to view everything in gloomy gray and could appreciate everything as it is.

Glare can impair your ability to see properly even when it poses no danger. Polarized sunglasses are frequently used by outdoor enthusiasts and athletes in order to see more precisely. In comparison to non-polarized sunglasses, polarized sunglasses may also provide you with a more realistic representation of the color.

According to research, sunlight glare might make you tired. Glare makes your eyes work harder as they attempt to make sense of the data, they are taking in. Eye strain is another name for this type of overwork, which can make your eyes feel worn out, painful, or hard to stay open. With a good pair of polarized sunglasses, this all can go away within seconds.

After hours of combating sun glare, users of polarized sunglasses frequently report feeling less worn out than normal. Most everyday scenarios can benefit from wearing polarized sunglasses.

It’s crucial that you test out a pair of sunglasses that are marked “polarized” because there is no physical difference between polarized and non-polarized lenses. Or, here’s how to determine whether the lenses you currently own are indeed polarized:

While looking at a computer screen, cock your head to the left and right. If your sunglasses are polarized, tilting your head back and forth should make the display appear to grow brighter and darker.

Or you could visit an optical or pharmacy with your eyewear. Pick up a set of polarized eyewear off the shelf. Put the lenses of your sunglasses and the store’s sunglasses at a 90-degree angle. Your sunglasses are polarized if the combined lenses turn dark or almost black.

You cannot simply rub off this protection with whatever you can find since it requires care. Polarized lenses need to be cleaned properly and with care. So, to help you, here is a guide:

Utilize a microfiber cloth or a lens cleaning product made especially for polarized lenses. The lens polarization coating can be damaged by common glass cleaning or soap and water.

To reduce the quantity of reflected light that reaches the eye, sunglasses lenses can be made with an almost undetectable filter. In addition to reducing glare, polarized glasses improve visual clarity and comfort by sharpening and clarifying pictures. Nevertheless, they can improve your eyesight and reduce some eye strain.

While UV light absorption has nothing to do with polarization, many polarized lenses now contain a UV-blocking material. To put it another way, polarization and UV protection are not the same thing. They are very different from one another. Polarized lenses lessen the glare that makes you squint in the sun, while UV protection sunglasses shield your eyes from damaging sun rays.

While UV-blocking lenses are meant to protect your eye’s, polarized lenses are meant to reduce glare so you can see more clearly and comfortably, which means less squinting! Video gamers, fans of water sports, and people who don’t like glare in general love these lenses.

In order to exclude light and lessen glare from reflecting or bright objects, polarized lenses were developed. Non-polarized lenses provide light protection, but they lack an integrated filter to cut down on glare or block off horizontal light rays.

Yes. They can be especially useful when it’s sunny outside and when engaging in water-related activities like boating or fishing. Polarized sunglasses are excellent for winter activities since they may help lessen glare from the snow.

Typically, yes. However, they could make it more difficult to read the LCD dashboard displays well. Furthermore, using them at night may reduce visibility.

Pilots are advised against using polarized lenses because they may impair their ability to see the cockpit’s liquid crystal instrument displays while in flight. This might be a serious safety risk.

You’ve probably heard of polarized sunglasses before, but to solve the problem, it’s important to understand why this “black screen” phenomenon occurs when you’re wearing them. (Don’t care about the science? Skip to the end of this article for the quick fix.)

Light is made of particles called photons, which travel through space like a wave, zig-zagging back and forth on their way to your eye. Natural, unpolarized light consists of photons bouncing in many directions at once. But as soon as they strike certain types of reflective surfaces—like a body of water or an asphalt road—those waves will all begin vibrating in one direction, usually horizontally. This is what causes the intense glare that hurts your eyes when you look at sunlight on a lake.

Polarized lenses don’t just cut down on glare; they also protect the long-term health of your eyes. “Everyone should be wearing polarized sunglasses for maximum eye protection from UVA/UVB rays,” says Purnima S. Patel, clinical spokesperson for the American Academy of Ophthalmology.

Your gadgets contain polarizing filters, too. “These LCD screens are polarized to reduce glare, especially in bright sunlight—but so are sunglasses,” Patel says. “When the filters for the screen and sunglasses align in opposite directions, the light emanating from the screen with be cut out.” In other words, if the screen emits horizontally-vibrating light, and your sunglasses block all except vertically-vibrating light, no photons will get through and you’ll be stuck with a dark or entirely black image.

The use of digital lenses, also know as ‘free-form lenses’ or ‘high-definition lenses’, in ophthalmic eyeglasses is increasing in eye care practices all over the world. Although this technology has been around for quite some time, it is becoming more common and preferred. Digital lens processing offers a higher level of precision when creating the lens for both single vision prescriptions and multifocal prescriptions and also opens up the possibility to create extremely unique and versatile lenses in terms of shape and prescription. By using processing equipment that requires the measure, analysis and computation of lens data in the form of numerical digits, both surfaces of a lens can be directly surfaced with a high level of accuracy. Digital eyeglass lenses offer an unprecedented degree of customization. Therefore, with this improved level of precision a patient will experience more comfort in their prescription and a greater level of visual satisfaction.  In the end, we can compare a regular lens to a tube television and a digital lens to a plasma flat panel television. Due to the manufacturing process, a digital lens allows for more peripheral vision and a sharper picture.

Just tried out a fix for the black-out + polarized glasses problem with the a7iii, i.e. putting on a protective glass on the screen. And voila, it works, to some extend.

The screen is now fully visible, but as with many other things and polarized glasses, the tint of the screen changes with rotation. My suspistion is that the adhesive between the glass and screen diffracts the light from the display to become more scattered (less polarized) thus allowing various colors and light to get through the polarization of the sunglasses.

Might explain why most smartphone screens tend to be reasonably visible (as in, you see visual artifacts but at least it"s not pitch black) with polarized glasses.  Or smartphone manufacturers have taken this phenomenon into account and include QWPs by default.

The A7M3 is the only product I"ve used that went pitch black with my prescription polarized glasses.  To the point where the first time I took it out when wearing the glasses, I thought the camera was broken.

Turns out that my current phone has an AMOLED not LCD, I could have sworn otherwise, but I"ve definitely had OK results with my glasses and other LCDs.

Polarized, or anti-glare, sunglass lenses reduce light glare and eyestrain. Because of this, they improve vision and safety in the sun. When working or playing outdoors, you can become frustrated and even temporarily blinded by reflected light and glare. This is a potentially dangerous situation that polarization can prevent.

Usually light scatters because it bounces at varying angles off an object’s uneven surface. But if the surface is smooth, as with calm water or a flat piece of sheet metal, light reflects at one angle. When this light reflects right in your eyes, this is what we know as glare. Polarized sunglasses reduce glare and solve this problem.

Polarized lenses have a special chemical applied to them to filter light. The chemical’s molecules are lined up specifically to block some of the light from passing through the lens. Think of it like a miniblind hanging in front of a window. Only light that passes through the blind’s openings can be seen.

As a result of this filtering, the image you see with polarized lenses is a bit darker than usual. But objects look crisper and clearer with polarized lenses, and details are easier to see.

People who use polarized sunglasses often say they are less tired than usual after hours of battling sun glare. Polarized sunglasses can be a good choice for most everyday situations. These are some specific situations when polarized sunglasses may be especially helpful:

Golfing. Some golfers feel that polarized lenses make it hard to read greens well when putting, but studies haven’t all agreed on this issue. Many golfers do find that polarized lenses reduce glare on fairways, and you can remove polarized sunglasses when putting if that’s your preference. Another benefit? Though this would never happen to you, golf balls that find their way into water hazards are easier to spot when wearing polarized lenses.

Most snowy environments.Snow causes glare, so a pair of polarized sunglasses are usually a good choice. See below for when polarized sunglasses may not be the best choice in snow.

when driving at night. You can buy polarized glasses that are supposed to help reduce glare when driving at night. Use caution when considering these glasses. Polarized night driving glasses may do more harm than good.

Keep in mind that if your sunglasses are labeled as blocking the sun’s harmful ultraviolet (UV) rays, it does not mean they are polarized too. Polarized lenses will have a label saying so.

Known as the sunnies to sport for athletic use (hiking, boating and the like), most people who typically wear prescription glasses can benefit from a solid pair of polarized sunglasses. Similar to how UPF-protective clothing and sunscreen help bask off harmful UV rays, so is the case with these sunglasses, as they help control the amount of reflected light hitting your eyes.

We turned to a board-certified optometrist who explained what to look for in the best polarized sunglasses and also pulled the top styles to shop for this season.

Reflected light in any form can cause discomfort and reduced visual performance — specifically, acuity and decreased contrast — so these special lenses help alleviate this eye-ridden distress.

Now, many polarized sunglasses exist on the market, including frames from GlassesUSA, RAEN and even Dick’s Sporting Goods. Many of our favorites are unisex, too.

Polarized lenses have some limitations and should only be worn in suitable conditions, according to Hoff. Specifically, they’re suitable for driving in bright sunlight, around water, snow and sand.

Though great for a variety of purposes, you don’t want to wear polarized sunnies all the time. Since these lenses will interfere with LCD (liquid crystal displays), they’re not recommended for airline pilots or heavy equipment users that utilized LCD instruments or screens.

“Polarized lenses make it difficult to distinguish shades of white and mask ice patches making downhill skiing and snowboarding difficult,” Hoff notes. “Polarized lenses can also cause you to see the tempering pattern on windows, say, when it looks like a grid pattern and can be distracting while driving when you see them in car windows.”

“Polarized lenses are designed to reduce reflected light from flat shiny surfaces like glass, sand, snow, water and the road to increase visual comfort and a sharper image,” Hoff explains. “Polarized lenses have filters oriented perpendicular to the reflected light to absorb the intense beam of light, too.”

They’ll likely be clearly labeled but if you want to test for polarization, orient them 90 degrees apart, per Hoff. “If the lens in question is polarized light will be totally blocked, if not light will pass through,” she notes.

However, use caution whenever digital displays are used in sports. “Some cycling handlebar displays are not compatible with polarization,” Hoff says. “Also, due to decreased depth perception with polarized lenses, avoid polarized sunglasses with ball sports such as baseball and tennis, and mountain bike riding.”

Wearing tinted or polarized lenses at night is not recommended unless prescribed for certain ocular conditions by a qualified Eye Care Practitioner, per Hoff.

Interestingly enough, “polarized sunglasses block out a significant amount of light and studies show they do not help with night driving glare,” Hoff adds. “They can actually be harmful because in low light conditions too much light is blocked reducing acuity and contrast to unsafe levels for driving.”

Polarized sunglasses reduce glare from surfaces such as water, snow, and glass. Glare distorts the true color of objects and makes them harder to see. Polarized sunglasses can be helpful in any situation where you need to see clearly and avoid hazards.

They do this by blocking horizontal light waves—the type that most surfaces reflect when causing a glare. Only vertical waves make it through the filter in these lenses.

Polarized lenses are available in a variety of colors. Their shade depends on the material used to make the lenses. The most common colors are gray and brown, but green, yellow, and melanin color are also popular.

Driving: More motor vehicle accidents happen when there is glare. Glare can make it harder to spot hazards and react to them. Polarized sunglasses block glare and make it easier to avoid danger when driving.

Playing outdoor sports: Similarly, polarized sunglasses help athletes see with greater clarity so they can safely maneuver while competing or practicing.

Polarized lenses aren"t right for everyone. Some people feel dizzy or disoriented when they look through polarized lenses. Others say these lenses make everything looks 3-D. Tinted lenses might be a better choice in those cases.

In some professions, people need to read digital numbers on a liquid crystal display (LCD). Pilots are a prime example. Polarized lens can make information on an LCD display hard to read, so they"re not a good option for people in those situations.

Some polarized lenses are marketed to help reduce glare while driving. Because they block some light, though, they should not be used at night. Polarized lenses can also make it harder to see icy patches on the road.

A high-quality pair of sunglasses will usually have polarized lenses. If you"re not sure:Take your sunglasses to a drugstore or optical store. Grab a pair of polarized sunglasses from the shelf.

Polarized lenses are helpful when you"re driving or participating in sports. They aren"t right for every situation, though. If you"re driving at night, navigating icy patches, or using LCD devices, these lenses make it harder to see clearly.

Yes. They can be especially helpful on sunny days and for activities that take place on or near water, such as boating or fishing. Polarized sunglasses also can reduce glare on snow, so they"re great for winter sports.

Polarized sunglasses are all the rage these days. And why not? There are many benefits to wearing polarized lenses, such as reducing eye strain and improving vision by blocking excess glare. Heck, for some people, polarized sunglasses can even help lessen or eliminate headaches.

All of which is great if you are planning to buy new sunglasses. But what if you already own a pair and don"t know or remember if they’re polarized? Do you have to just buy a new pair? Not necessarily. There are several easy ways to determine whether or not your current sunglasses are already polarized. You’ll find tips that might save you more than money—they could also save your eyesight and help prevent macular degeneration. And for superior clarity and protection, check out Xperio UV™ Polarized Sun Lenses for the best vision under the sun.

This is so meta it might just blow your mind, but if you wear your sunglasses while reading this article, you may be able to determine whether they are polarized. That"s because most modern computer screens use the same glare-reducing technology as polarized lenses. If you rotate your glasses sideways while looking at a computer monitor through polarized glasses, portions of your screen will become blank or go dark. The same is true of LCD display screens such as the ones on a gas pump. Crazy, right?

One of the primary benefits of wearing polarized lenses is cutting down on glare, such as the glare you get off a car windshield. Polarized sunglasses are also great at reducing the glare of the sun reflecting off water. If your sunglasses are polarized, instead of only seeing the surface of a lake or river, you will suddenly be able to see through the glare and into the water below. Catching all those fish down there, on the other hand, is up to you.

If you know somebody who owns polarized sunglasses, figuring out if your own lenses are polarized is as easy as phoning a friend. All you need is their cooperation—and, of course, their glasses. First, hold up your glasses and theirs simultaneously and look through both pairs at the same time. Then, rotate one pair of sunglasses about 60 degrees. If both pairs of glasses are polarized, the overlapping area will darken as they filter out excess light. If your pair isn"t polarized, however, you won"t notice any difference.

Most new polarized sunglasses come with a sticker on one of the lenses stating that the glasses are polarized. But some companies take things a bit further and actually mark their polarized sunglasses in a more permanent fashion. Some even etch the word "polarized" into the bottom edge of the left lens. As a result, even if you bought your glasses months or years ago, it"s possible a quick inspection may turn up clues you never even noticed before.

If you determine that your sunglasses aren"t polarized, a trip to your eye doctor can solve this problem. Your local eye doctor is able to swap out the lenses in any frames for polarized lenses, typically in a week or less. If you wear glasses full-time, you can even have your eye doctor add your prescription to your polarized sunglasses.

But what if we told you that times are changing, technology has advanced, and you now have the option of choosing a pair of cockpit-friendly, digital-device compatible polarized sunglasses?

Today we will share exciting news about a visionary sunglasses brand that has brought polarized lenses to everywhere from the golf course to the ocean and now – to the cockpit.

When light hits a flat horizontal surface (like water or snow), it is reflected back more intensely, and also in a horizonal direction. This type of light which is retransmitted in mainly one direction is said to be polarized.

The lenses of polarized sunglasses have a special laminated filter that blocks much of this powerfully magnified horizonal reflection and allows just the vertical light through.

Non-polarized lenses work by simply reducing the intensity of the light that passes through them and into our eyes. Basically, they just act as dimmers and make the light less bright.

Non-polarized lenses do not have the benefit of a filter to decrease the blur, haze and glare that comes from intense horizontal light reflecting off of flat surfaces.

Traditional polarized lenses present an issue in the cockpit largely because of the way that their light-filtering technology interacts with digital devices.

A byproduct of the filtering is that it often makes it more difficult – if not nearly impossible – to read LED and LCD screens on devices like cell phones, tablets or instrument panels.

The polarized lenses in Revo brand shades feature unique technology that other brands lack. This special tech makes Revo a polarized lens that we can finally recommend wearing in the cockpit.

The secret to Revo’s singular effectiveness lies in its ability to manage the full light spectrum. Revo has designed specialty lenses to combat blue light, glare and UV radiation while remaining digital-device friendly.

We are all plenty familiar with the blinding glare that can envelop the cockpit. Revo lenses protect our eyes and reduce the strain, fatigue and squinting.

Phones, tablets, LCD/LED instrument displays – all the screens in the cockpit can still be easily viewed and read while wearing Revo polarized glasses.

The top side of a Revo lens is given a “polarized film” to reduce glare and eye strain. Over the top of the film are 3-6 layers of “exclusive mirror coatings” – the secret NASA technology component. Finally, an “oleophobic coating” helps keep oil and fingerprints at bay.

Revo may not reveal all of their proprietary secrets, but it is clear that they have put a great deal of research, thought and care into crafting their high-performance lenses.

Material: The lenses are treated with a special hydrophobic filter, which is scratch-resistant and water-repellent, so even in the rain the lenses are perfectly transparent. Each set of VIF sunglasses contains a lens with the colour of your choice and a black polarized one, which reduces unpleasant glare in intense light. Thanks to the simple system of the frame, you can change the lenses in less than 3 seconds. The rubber of the nose-piece and temples stay grippy even when wet, so the glasses will stick to your nose during any sports activity, they ensure comfort even when the glasses are worn for a longer period of time and most importantly, during a potential crash.

Polarized lenses contain a layer of triacetate (TAC), which reduces glare, increases image clarity and increases scratch resistance. TAC lenses are extremely light and also absorb less moisture, thus, the glasses do not fog up.

TIP: Do you know how to make sure that the glasses really have a polarized filter? If you place two polarized glasses behind each other, it is visible through them as normally, however, if you rotate one 90°, they will become opaque. Crossing both polarized lenses, filters out the vertical and horizontal waves so that no light passes through.

Polarized lenses are a type of sunglasses lens that reduces light glare. Like all sunglasses lenses, they allow you to see more comfortably in bright or sunny situations. Unlike regular sunglasses, however, polarized sunglasses allow you to see despite the glare caused by light bouncing off of other surfaces, like the hood of your car.

In most situations, polarized sunglasses increase visual comfort by filtering both ambient and reflected light. Viewing a bright scene through polarized lenses can also help you see colors more vibrantly and details more clearly than you would without polarization.

It’s important to note that, while polarized lenses can reduce or eliminate the blinding glare of upwardly reflected light, they don’t necessarily provide protection from harmful UV rays. When selecting any sunglasses, including polarized sunglasses, be sure they’re labeled with 100% UVA and UVB protection.

Another effect of polarization is increased contrast, which contributes to visual clarity as well as enhances colors. So even if you’re looking at a bright, sunny scene, polarized shades can allow you to see vibrant colors rather than just the brightness of reflected light.

For certain activities, including daytime driving, water sports and winter sports, you may benefit from wearing polarized sunglasses — especially if light is bouncing off surfaces and into your eyes.

Fishing:When you’re on or near a body of water, polarized lenses can help you see more clearly by cutting down on the glare from the water’s reflection. This also means you’re better able to see past the surface of the water, which provides a huge advantage for fishers.

Water sports:If you’re sailing, kayaking or canoeing — or doing any number of other water sports — polarized lenses can ease the strain on your eyes from the water’s glare. Plus, they’ll help you see more underwater wildlife.

Winter sports:While you may think polarized goggles or glasses would be helpful while skiing or snowboarding, not being able to see the glare from snow and ice during these activities can actually be detrimental. That’s because this reflection alerts you to dangerous icy patches, which allows you to avoid them.

Bicycling and running:Using polarized sunglasses comes down to personal preference. Some cyclists and runners wear polarized shades to filter both ambient and reflected light, while others feel safer maintaining the ability to see reflected light.

Looking at screens: When it comes to looking at screens — like your smartphone, laptop or an ATM — polarized sunglasses aren’t going to do you any favors. That’s because the anti-reflective coating on polarized lenses distorts digital screens, making them appear faded or completely dark depending on the angle from which you’re viewing the screen.

Polarized lenses filter both ambient and reflected light, so they can really ease the eye strain that comes from being in a bright environment. This not only improves your eye health and helps you avoid distractions and temporary blindness caused by glare, but it also helps you see bright scenes more clearly and colors more vibrantly.

Polarized sunglasses can make it difficult to see LCD screens like phones and laptops. This can be especially problematic if you rely on a digital dashboard display or cell phone when routing in your car. If this is the case, you may want to opt for non-polarized lenses when you need to see a map while driving. In low-light situations, polarized lenses may actually block too much light

Prescription sunglasses are available with or without an anti-reflective coating. Choosing polarized lenses can be worth it if you’ll wear your sunglasses for daytime driving or boating activities, but you may want to opt for non-polarized sunglasses if these will be your only pair of shades

In general, everyone needs UV protection for their eyes, so the most important consideration when buying sunglasses is to make sure they offer 100% UVA and UVB protection. And while an anti-reflective coating can also help keep you safe in the sun by reducing harsh glare, you should talk to an eye doctor about whether polarized lenses are right for you.

This bit of magical privacy is achieved through the way typical LCD (liquid crystal display) screens are constructed. Most light from the sun, light bulbs, or that twinkle in your eyes is actually a big messy wad of electromagnetic waves pointing this way and that. This is also the case with the source light for LCDs.

In any case you have to be careful, because not all screens are created equal so results may vary. And it probably goes without saying that this only works with LCD screens, so put the screwdriver down and slowly back away from that plasma screen.

But what about polarized lenses? It’s not uncommon to see the word “polarized” next to “100% UV protection” on the tag for a new pair of sunglasses. What does that mean? Will polarized lenses protect your eyes from ultraviolet light too?

Non-polarized sunglasses are designed to reduce the intensity of any light. If your lenses offer UV protection, they most likely contain special dyes and pigments that absorb ultraviolet rays, preventing them from reaching your eyes.

Polarized lenses are treated with a chemical that filters out light. However, the filter is applied vertically, so vertical light can pass through, but horizontal light cannot.

That is the general idea behind polarized lenses. Some vertical light can pass through the filter, but horizontal light, or glare, is unable to make it through.

Even when glare is not a safety issue, it can impact your ability to see clearly. Athletes and outdoor hobbyists often use polarized sunglasses so they can see with a higher degree of precision.

Polarized lenses may not be the ideal choice in every situation. For instance, devices that use LCD displays emit polarized light. If your car uses LCD displays for basic controls, you should avoid polarized sunglasses while you drive.

Polarized lenses will not protect your eyes from UV damage more than standard 100% UV lenses. However, they can give you clearer, more accurate vision and alleviate some eye strain.

If you find yourself squinting a lot, even when you’re wearing sunglasses, consider investing in polarized sunglasses. You may find them to be a more comfortable option.
