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.

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.

From the company that started the polarized sunglasses trend hands-on, Ray-Ban is offering the Erika Polarized Sunglasses for less than $200. Wonderfully, the nosepiece isn’t too thick (which is perfect for avoiding foundation makeup from transferring) and we love its simplistic, match-all design.

If you’re tired of your old black shades, step up the game with RAEN’s Wiley Square Sunglasses. The pair has a handsomely crafted black-and-brown design, along with sturdy temples and sharp look.

Shop one of Dick’s Sporting Goods’ top sellers: Oakley’s Holbrook Polarized Sunglasses. With a sportier look and feel, they have a coveted lightweight frame with different types of polarized lenses to choose from. Plus, they also come in a blue tone.

Don’t pass up the classic aviators this season. Coach’s Polarized Sunglasses are a great score for the season. With a slim nature and gold-toned hues, they’re chic and classy (especially when paired with a designer clutch and new pair of shorts).

If Audrey Hepburn and Kate Middleton had a sunglasses collab, it would look a little something like RAEN’s Norie Cat-EYe Sunglasses. Not only do they have that tortoiseshell look (that won’t go out of style, BTW), but the frames are rounded to suit any face shape.

If we’re being honest, QUAY has some of the sweetest shades in its repertoire. Namely, its Sweet Dreams Polarized Sunglasses are less than $100 (in other words, add to your cart now) and its thin nosepiece band will provide lightweight support in warmer temps.

Blenders Eyewear has the surfer-inspired, cool blue polarized sunglasses we’ve all been waiting for. Its Surfliner Polarized Sunglasses are budget-friendly, add a touch of vibrancy to your summertime look and look great on anyone. They’re a lovely unisex option, too.

Give your eyes the clarity and protection they need without the high ticket price. Foster Grant’s Marli Polarized Sunglasses are some of our favorites on this list (and ones we recommend IRL), so pick up this moody tortoiseshell pair while you still can.

If athletic polarized sunglasses are more your speed, you’ll love Nike’s Trainer Polarized Sunglasses. They’re the perfect blend of quality and affordability, too, and they’re apt for sports and basking in the sun’s rays all the same.

Elevate your look tenfold with Michael Kors’ Anaheim Polarized Sunglasses. These on-trend, oversized sunglasses will look dynamite with your best bikini and cover-up this season, undeniably, and they’re conveniently on sale right now.

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.”

So, the lens is tinted to absorb visible light. “Outdoor sunglasses are designed to absorb up to 85% of visible light,” she adds. “We need to let some light through for safe mobility.”

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.”

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.

The sun is returning for another bright summer, which means it’s time to relax and read by the pool. So you pull out your phone, don your shades, and…you can’t see a thing on the screen. What gives?

This annoying phenomenon happens with all kinds of electronics, including phones, tablets, and computer monitors. Even with the brightness cranked up, the display appears dark, purple, or in some cases, completely black when you wear sunglasses. The culprit? Polarizing filters.

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.

Polarizing filters absorb light waves that vibrate along a certain axis. In the case of polarizing sunglasses, they absorb the horizontally-vibrating waves. That means that only vertically-vibrating waves get through the filter and reach your eye. This reduces the intensity of reflective glare without blocking too much of the surrounding light.

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.

Thankfully, there’s an easy fix: Turn the screen 90 degrees in either direction. This will align the polarizing filter on your screen with the one on your sunglasses, and the light from your screen will be able to pass through to your eyes.

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.

ARE YOUR SUNGLASSES POLARIZED? If not, it might be time for a new pair. Shop for polarized sunglasses at an optical store near you or an online eyewear retailer

Polarized sunglasses and the infotainment screen: Two great technologies that don"t play well together. Polarized lenses cut glare and can bump up contrast, effectively sharpening your view, but they can make it nearly impossible to see some modern nav screens or head-up displays. Since it"s less than practical to swap your car to match your favorite sunglasses, here"s a primer before you invest in new summer shades.

HOW THEY WORK: Horizontal light waves, like those reflected from the road or your dashboard, severely hinder your vision in bright light. Polarized glasses block these waves, making surroundings seem clearer and helping to reduce eye fatigue.

THE DOWNSIDE: Since head-up displays function by reflecting light horizontally off windshield glass, polarizers can make these displays seem to disappear. LCD infotainment screens and digital gauge clusters also use polarizing filters and can go dark when seen through glasses polarized in the same orientation. Some carmakers combat this problem by reorienting those light waves on an angle; depending on the angle, this can help but not entirely fix the issue.

THE ALTERNATIVE: Half-silvered lenses with a gradient tint let in more light than the polarized variety, with the reflective coating blocking more at the top of the glass than at the center or bottom. This protects your eyes from the sun but lets you see what you need on the dash.

Some brands paint cheap glass with a thin polarizing coating. These scratch easily, distort vision, and may let in harmful levels of UV light. Choose companies that use quality optics and specialize in polarization, like Randolph Engineering (pictured, $179), which began supplying sunglasses to the U.S. Air Force in the Seventies.

I just got polarized prescription sunglasses this morning. I was worried because I saw this thread after I ordered them back on 9/29, and I hadn"t thought about that reading the display on my bike or reading the fish finder on my boat. I went out for a ride today, and didn"t have any difficulty reading the display, but it was kind of overcast so I"m not sure if bright sunlight is going to cause an issue or not. Haven"t tested my fish finder yet.

Take a look at any professional athlete competing in an out-door sport: baseball, cycling, golf, fishing, shooting, skiing, tennis, track and field, beach volleyball, sailing… the list goes on. What do they have in common? Most of these athletes wear sunglasses. They are no longer an accessory, but a piece of equipment just as important as the rest of their uniform and gear. It ensures that athletes compete at their best without interruption or distraction. Sunglasses are an essential tool for optimum vision, especially in action sports where split-second decisions mean the difference between winning and losing, or even preventing an accident. These athletes demand the most cutting-edge

However, polarized sunglasses are not limited to the elite competitor. Because of their affordability, they can be used by everyone—even if you aren’t a professional athlete. The reason they are so popular is due to the increased visibility and performance they provide the wearer in everyday situations. While athletes use them to maximize their performance, the consumer can use them to maximize their experience. Whether it’s taking a relaxing hike, enjoying a casual Sunday drive, or relaxing with a book on a beach, polarized sunglasses can eliminate the distracting glare that causes visual discomfort in any sunny situation. Polarized sunglasses can best be described as a sun-glass option for everyone.

Some of this light lands directly on the eye, while some of it is reflected off of surfaces like roadways or water. This reflected light is slightly bent and scattered in all directions according to its angle of incidence on the reflective surface; some of these reflected light rays become polarized.

When a bundle of light hits a flat surface, it becomes polarized, i.e., is reflected only hori-zontally. It becomes concentrated and is blinding to the viewer. This intense reflection is commonly referred to as blinding glare. The reflections can be uniform, like light reflected off of the road ahead of a driver or from another car’s hood. The reflections could also be from non-uniform or changing surfaces, like running water or a non-uniform patch of ice on the road. No matter the case, the desired requirement is to filter out the distracting reflected light and provide a clear viewing experience for the wearer.

The properties of polarized filters are used in a variety of fields such as chemistry, engineering, professional photography, geology and astronomy. As an example, polarized filters can be used to highlight clouds for photographers or detect the amount of stress in lenses in a frame by observing the amount of birefringence (internal stress) induced. This is used in a variety of engineering stress tests and is used in many finishing labs to ensure proper lens fit with minimal stress placed on the finished lens.

One can think of polarized lenses as linearly aligned slit filters used to block incident light of a particular orientation. Think of the filter acting like Venetian blinds: The horizontal blind blocks incoming light from above and below. By blocking this light, it provides a clearer view when looking out a window; there are fewer distractions and reflections observed. For optimal viewing, a polarizing lens should stop horizontally polarized light from view while allowing vertical light rays through the lenses.

As stated, reflected light off flat surfaces becomes polarized in a horizontal direction to the viewer. It causes blinding glare. This light obstructs images from the observer, such as the bottom of a shallow streambed. By eliminating the reflected blinding glare from water, the wearer is able to see below the surface of the water and clearly identify rocks and fish. The advantage in this example is safely avoiding obstacles while wading through the stream, locating the fish one might be trying to catch as in fly fishing or from a boat.

Another instance in which polarized lenses provide an advantage is while driving because of the elimination of glare from oncoming traffic or the road itself. Both the metal finish from other cars and the road itself can be quite reflective on bright days, but this effect is amplified if it has recently rained or snowed. Suddenly these surfaces are reflecting much more light and in many more directions. Polarized lenses filter and reduce the most intense horizontal reflections from these surfaces. This ensures that the wearer’s eyes are relaxed and don’t feel strained, which can result from even a short drive.

Polarized lenses have never been suitable for pilots of major aircrafts. The Federal Aviation Administration (or FAA) advises pilots against wearing polarized sunglasses. The FAA specifically mentions polarized lenses creating striations and decreased visibility through aircraft windscreens. This can create much more visual noise (a colorful rainbow effect and visual obstruction)

for the pilot. This is extremely important when spotting other aircraft in high-traffic situations during takeoff or prior to landing. Polarized lenses effectively mask the sparkle of light from other aircraft, which is necessary to provide an additional measure of safety for pilots in these high-traffic situations.

The FAA even discourages the use of polarized sunglasses due to reduced visibility of instrument clusters equipped with anti-glare filters. This is a result of newer instruments incorporating LCD technology for digitally displaying flight data such as altitude, pitch and yaw of the plane. A polarized filter can dim or even make gauges disappear entirely, which can result in an unsafe situation for the pilot. The AR surface of the gauge helps reduce reflections from the sun or other lights in the cockpit that might mask the LCD display. However, this AR cannot reduce the problem of polarized sun lenses.

To the average consumer, the largest drawback is the disappearance of LCD screens like smartphones, car gauges, radio displays and gas pumps while wearing polarized sunglasses. LCD displays utilize a polarizer, placed at 45 degrees to ensure proper color contrast and clarity of the picture. This isn’t a problem for the wearer when their lenses are aligned in a parallel orientation to the polarizer in the LCD screen. But when the wearer is looking at an LCD device at a perpendicular angle to the polarizer, the image turns black. The same effect occurs if you hold two polarized lenses at 90 degrees to one another.

While this has been more of an issue in the past when looking at digital displays such as GPS navigation, advances in screen technology displays emit light at various angles to ensure that displays can be seen through polarized lens filters, though potentially dimmed. This is still a critical point of note when choosing lenses for those who work outside and rely on digital displays. I have asked many engineers and construction workers to bring in their digital devices and explore how their screens look through polarized lenses. This has saved costly remakes and patient dissatisfaction from choosing the wrong lenses for their needs.

One other note of importance is that some skiers prefer tinted lenses instead of polarized lenses because of the reduced visibility of ice. Since the reflections are eliminated, skiers might not be aware of the ice until it is too late. Those competing in slalom events need to know where they have to check their speeds to safely take the corners. Although competitive skiers wear goggles for competition, many recreational skiers will wear their sunglasses and go straight from the mountain to their après-ski activities. This is another point of mention with patients who express interest in using their sunglasses on the mountain.

Despite these cautions, the advantages of wearing polarized sunglass lenses outweigh the disadvantages. It is important to consider lifestyle and overall use of the sunglasses to make the most appropriate decisions concerning patient lens selection. It is very important that these limitations are understood and easily explained by the dispensing optician for troubleshooting purposes or to discuss how polarized lenses will work for patients’ specific needs.

The advantages to the consumer are invaluable in creating a better visual experience during daytime activities. First, they remove reflections in the form of scatter (“visual noise” as the reflected short wavelengths are polarized and crisscross over one another). This is called Rayleigh’s Effect and is a major reason that polarized lenses are so comfortable overall. Secondly, polarized lenses increase color saturation to the viewer by increasing edge contrast and color variations of an object. Because of this, environments look more vivid than if observed by the unaided eye: Leaves are a vibrant green, and the sky is a darker hue of blue. By eliminating blinding glare, polarized sunglasses provide visibility of an otherwise hidden object for the wearer. This is important for spotting debris and road imperfections whether on a bicycle, motorcycle or while driving a car.

Anti-reflective coatings, especially on the back surface of polarized lenses, are a requirement for the best sunglasses. These coatings improve acuity while driving and should be recommended to anyone wearing sunglasses when commuting. This option eliminates distracting reflections from objects behind the wearer, most noticeably the image of the wearers’ eye reflected on the inside of the lens, which can obstruct vision. Some premium anti-reflective coatings also prevent harmful UV from being reflected into the eye when the sun is behind the wearer.

The acuity polarized lenses can provide to the wearer is also important to mention. Colors look truer and better defined than a neutrally tinted sunglass. Depth perception and horizon differentiation is improved due to this filtration. This makes a big difference to the golfer following a ball bouncing down the golf course or a spectator at a baseball game tracking the ground ball from the infield into the outfield. However, golfers may have difficulty “reading the green” because of the individual grass blade reflections (the grass blades are pointed in all directions) and as a result, many prefer golf-specific tints.

While you don’t need polarized sunglasses to watch these events happen in real time, they are more comfortable and noticeably reduce eye fatigue over the course of several hours of watching the same events.

Comfort is a major factor to wearing polarized sunglasses. The eyes can become tired after viewing the same activity occur for several hours. This is most evident to those with long commutes or individuals who drive for a living—they are fixated for hours at a time on a road emitting horizontally reflected light and blinding glare. This reflection can cause discomfort, sensitivity and distraction. Polarized lenses help to reduce this fatigue by filtering “noisy light” (or distracting reflective polarized light). This can relax the eye, eliminating eye strain and making the wearer more comfortable.

Part of the necessity of sunglasses is to protect the eyes and the adnexa (the skin surrounding the eyes) from UVA and UVB light. All polarized filters are engineered to block these specific wavelengths of light waves regardless of the material of the lens. However, very light polarized lenses may not be as UV-absorbing as dark sun lens densities. Significant absorption is important for the health of the eye and ensures protection from damaging ultra-violet radiation that is associated with cataract development and retinal damage from prolonged exposure. Large sunglass frames act like a shield, protecting the eye and the sensitive skin around the socket. Sunscreen is used to protect the body from sunburn, so think of polarized sunglasses as sunscreen for the eyes.

This is also very important to consider at higher altitudes where the UV and visible light is much more intense. Sunlight includes potentially damaging high-energy blue-violet radiation (415 to 455 nm) of concern by ECPs and a predominant conversation with patients using digital devices. This light, associated with retinal damage is also filtered by polarized lenses. This makes for another crucial talking point when recommending polarized lenses to the wearer.

Polarized sunglasses act like sunscreen for the eyes by blocking these damaging frequencies of light. In fall 2012, Anderson Cooper suffered from sunburn to his cornea (commonly referred to as snow blindness, the clinical term is photokeratitis) while reporting for “60 Minutes.” He was recording a segment from a ship off the coast of Portugal without wearing any eye protection for only two hours. Even with limited exposure to light reflected from the water’s surface, it was enough for him to lose sight in his right eye for 36 hours. While the effects of a corneal burn are temporary, the long-term effects of intense UV exposure could result in cataracts, pingueculae, pterygia, skin cancers or permanent damage to the eye.

Sunglasses can also protect the bones that form the eye socket from projectiles. According to the National Eye Institute, approximately 800,000 total eye injuries occur in the United States annually. Of those total recorded injuries, roughly 100,000 occur while engaged in sports; but it is estimated that 90 percent could have been prevented with proper eyewear. Sunglass manufacturers purposely pair Trivex or polycarbonate lenses in sport frames for maximum protection.

Large sport sunglasses wrapped close to the face can provide maximum eye protection in the event of an impact. A skate-boarder can feel secure knowing that their eyes are protected from dust, debris and grit. Sport shooters can be confident that spent casings won’t become distracting projectiles. Volleyball players can concentrate on setting up their next attack after diving into the sand, not wiping sand from their eyes. Each scenario offers a solution to a common theme—the peace of mind that nothing will compromise the experience.

Polarized sunglasses in many ways sell themselves to the consumer. It is important to demonstrate the advantages and to be able to explain how polarized lenses will benefit the wearer whether they are recreating or competing. Reinforce to the viewer that polarized sunglasses ensure the highest quality of vision to maximize both their performance and experience. This way you will strategically align your practice to sell more polarized lenses, because polarized sunglasses are truly everyone’s most important piece of outdoor equipment.

We want what is best for our eyes to protect them from sun damage. Did you know that the most important thing about sunglasses is the UV protection. Choose sunglasses from a brand you trust to provide 100% UVA and UVB protection. Polarized lenses have a filter that block out glare but do not protect your eyes any more from UV exposure. The polarized filter is blocking out the glare from horizontal surfaces. It uses lens technology and specific filters to block out rays of light bouncing off horizontal surfaces and allows all other light to pass. This reduces the glare from wet road and water surfaces. This glare reduction makes it slightly darker which allows you to see more details. It also makes it easier to see past the glare on water surfaces so that you can see through the water, which is especially important for fishing. The benefits of polarized lenses are beneficial for people who are going to be wearing their glasses for driving, water activities, boating, fishing, and people who are sensitive to glare.

I do not recommend polarized sunglasses for action sports like mountain biking or trail running as the glare from wet roots is vital information for your eyes to warn you that the surface may be slippery. With polarized sunglasses the roots and other shiny slippery surfaces may appear dry. The glare from snow may also provide information to your eyes if the snow surface is icy. Keep this in mind if you are thinking of buying polarized snow goggles. Be sure that you are aware that glare may be helpful in some circumstances when you are navigating slippery terrain. Another thing to consider is that LCD screens can be more difficult to see with polarized sunglasses. The light passing through LCD screens may be horizontal, and all horizontal light will be blocked by your polarized sunglasses. An easy fix is to rotate your LCD screen 90 degrees and the light will be able to pass through the polarized sunglasses. Polarized sunglasses are not recommended for pilots who need to use LCD screen GPS or other instruments. Heads up displays will also be blocked by polarized lenses. Polarized lenses are great for improving visual clarity and reducing eyestrain due to glare but they may not be perfect for everyone.

What does “polarized” even mean? And, what are the benefits of polarized vs. non polarized sunglasses? Do non-polarized lenses really protect your eyes? These are the types of questions we all ask ourselves before splashing out on a new pair of sunnies or when we’re choosing replacement lenses for our favourite sunglasses. Read on to find out all you need to know. We’ll start with the all-important basics…

A polarized lens is one which is designed to reduce glare from reflective or bright surfaces. We apply a polarisation film to the outside of our lenses, which is created using a very delicate chemical process, to help filter out light. The chemical molecules in the film line up to proactively block out some of the light that passes into, and through, the lens, kind of like a blind might do with a window. Close the slats a little, and only some light can come streaming through – this is essentially how polarized lenses work.

For sunglasses, this means that they filter out ambient light as well as counteract glare. Technically, what’s also occurring is that the filter creates vertical openings for light – only light rays that beam in towards your eyes vertically can get through those openings. Polarized lenses therefore block out all horizontal light waves, including the glare created by light bouncing off flat surfaces like a window, car hood or patch of ice", as examples. So, you’re less likely to experience this “glare”, and it is safer for you when, for example, driving, as well as less irritating and stressful on the eyes themselves.

In order to make clear the difference between polarized and non-polarized lenses, we need to take a look at the non-polarized option. Non-polarized lenses, put simply, only offer protection from light; they do not contain a filter allowing them to cancel out surface glare. So, yes, they can protect your eyes from the sun and from associated sun damage – this is called UV protection, which is different from polarisation in any case – but they will still allow glare or ambient light through, unlike polarized lenses, which as mentioned above, are designed to reduce glare.

You might think that not being polarized is less advantageous, somehow, but in actual fact both modes have their benefits. So, before you buy any replacement lenses, let us fill you in on what the benefits are for polarized sunglasses vs regular so that you can make an informed choice. Let’s take a closer look…

As you might imagine, the benefits of polarization are many. They reduce eye strain, increase clarity of vision and remove glare, which means eyes are far more comfortable. When you repair scratched sunglasses, a polarized lens offers all of these advantages over its non-polarized counterpart. Although polarization, as a process, makes a pair of lenses a little more expensive to buy, it’s also true that you get what you pay for and sometimes it’s definitely worth spending a couple bucks more, especially when there are so many tangible benefits. Money isn"t everything, particularly when it comes to the health of your corneas, the quality of your vision, and also the stress you put your sensitive eye muscles under.

Reduced glare can also make activities such as driving safer, in many instances, because it means you’re not going to be suddenly blinded by reflected light from, say, a windshield or bumper. However, there are times when it might be more beneficial to take the non-polarized option – or take your polarized sunnies off.

There are some benefits to non-polarized sunglasses that are worth weighing up before you make a choice on your new lens option. For one, common non-polarized lenses can sometimes be a little more hard-wearing than treated lenses, although it"s up to you as to whether that would outweigh the benefits given in the previous section.

It"s also been found that non-polarized sunglasses may make white tones more true to their intended color, if that’s an issue for you. As a linked benefit, it can be easier to view LCD (liquid crystal display) screens with this type of lens. If you"re using an LCD screen, well, maybe you shouldn"t be wearing sunglasses anyway, would be our argument! But, anything LCD, like your car’s dashboard controls, your cell phone display, your LCD watch, as well as the info displayed on an ATM cash machine, will be affected if your lenses are polarized. Pilots, for example, don’t wear polarized sunglasses because it can make their instruments appear blacked-out. Meaning that non-polarized are the most beneficial in these cases.

There are also some situations in which more glare or light might be an advantage, too, making non-polarized lenses the better option. When driving, if conditions are icy, then non-polarized shades are better for seeing patches of ice on the road (this holds true if you’re skiing, too) – as polarized lenses would reduce glare, making the ice harder to spot.

This is a question we need to pick apart a little in order to give an answer. In truth, both polarized and non-polarized lenses will protect your eyes, if – and it’s a big if – they are made for UV protection. It’s whether they safeguard your eyes from ultraviolet rays that is the key query here, rather than ‘polarized vs non polarized sunglasses’. Polarized lenses and non-polarized lenses, protect your eyes from UV if they are labelled “UV blocking”. If they are not labelled as such, then, whether they’re polarized or not, makes no difference. They will not protect your eyes from UV rays.

Yes! You can repair scratched or damaged sunglasses with either lens type. We hold replacement sunglass lenses for all top brands, too. Simply decide which lens would be most useful and advantageous to you, and select the style that suits. It’s as easy as 1-2-3, all you have to do is think about where you’re going to wear your reinvigorated sunnies and what you’ll be doing when you wear them. Think about this before you buy, then get our lenses delivered straight to your door. Polarized are, with us, cheaper than you’d imagine, and we can fit them perfectly to your favorite frames, no problem at all.

Polarized sunglasses vs regular is a difficult question. Both polarized and non-polarized sunglasses have their place in our sunshine world! It really depends upon your own needs, what the shades will be shading you from, and so forth. As an example, if you"re thinking of wearing sunglasses when playing water sports, then polarized lenses,to counteract glare coming from refracted light hitting off the water, would be the best choice. If you"re going skiing and need the terrain to remain clear, as well as to spot icy patches, then maybe non-polarized glasses would be best.

Whatever you choose, make sure you go as far as you can with your budget and make sure to choose the best quality lens that you can. Sunglass Fix™ lens options offer both, and are of the highest possible quality, made by people (us here!) who truly care about all things lens-related. The wearer should wear the sunglasses, and not vice versa, so choose wisely, and choose what"s best for you – now that you know the difference!

Pampering yourself with polarized lenses allows your eyes to experience the comfort and rest that they desperately need. Polarized lenses will enhance the quality and comfort of your vision while making whatever you’re doing more enjoyable.

Polarized sunglasses work well to protect eyes from bright light and reduce glare, thereby making it easier to see. Polarized glasses are suitable for outdoor activities like fishing, diving, or skiing.

Polarized sunglasses reduce glare and lessen reflections to your eyes. These glasses have a chemical filter that blocks some of the light that is reflected off water, snow, and glass. This helps to improve your vision and safety while outdoors.

Polarized glasses have a special chemical filter on them that block some light as it passes through the lens. Essentially, the lenses scatter light so it all isn’t reflected directly into the eye.

When sunlight strikes a flat surface, it’s reflected at a horizontal angle to the eye, causing eye strain. The coating on polarized glasses filters out horizontal light while allowing vertical light to pass through the lenses. This helps to reduce glare, allowing you to see clearer images.

Polarized lenses have achemical coating that reduces glare that non-polarized sunglasses do not have. As a result, it might be more difficult to see in bright light with non-polarized sunglasses.

Polarized glasses allow vertical waves to travel through the lens, but they filter horizontal light waves, reducing glare. In contrast, non-polarized sunglasses only filter ultraviolet (UV) rays but do not prevent glare.

Polarized glasses do not protect against UV rays unless noted. Many polarized glasses also have UV protection, but you must look for this special labeling.

It can be difficult to see screens, like smartphones and tablets, while wearing polarized lenses. While newer polarized sunglasses have attempted to counteract, it’s common that screens will appear darker while wearing polarized sunglasses.

Polarized lenses are suitable for anyone spending time outdoors, especially when there is bright light. These lenses are primarily beneficial for these activities:

Driving during the day: Sunlight hitting the windshield on a clear day scatters the light into a bright distracting glare. Polarized lenses block this glare, allowing you to focus on the road and drive safely.

Polarized glasses will have a sticker or label to show they are polarized, but if you aren’t buying the glasses new, you can confirm they are polarized by following these steps:

Wear your sunglasses and look at a bright horizontal reflective surface like water. If the light intensity increases when you tilt your head, your lenses are polarized.

If you have two pairs of sunglasses, put one lens in front of the other and look into the light. You should be able to see through them. Tilt one of the glasses 60 degrees to the right. If it gets darker, both pairs are polarized.

If your glasses are new, look through the lens at the test tag and rotate the lens to a 60-degree angle. If the tag gets darker, you have polarized sunglasses.

Polarized sunglasses are the best option for people who spend a lot of time outdoors. Wear these sunglasses when driving or fishing to block glare and enhance visibility.

Like all sunglasses, factors such as material, frame, and brand will influence the final cost. Polarized sunglasses tend to cost between $25 and $450 or more.

You can buy polarized sunglasses at a variety of retailers, such as Oakley, Ray-Ban, or dedicated sunglasses retailers. Your eye doctor may sell some polarized options as well.

The benefits of polarized sunglasses for certain activities are undeniable. The glasses help to reduce glare and reflection, improving your vision. They also help improve clarity in brighter situations.

Polarized sunglasses will not protect your eyes from UV damage. You’ll need to look for labeling that notes the sunglasses also offer UV protection. Polarized lenses can reduce eye strain and allow you to perceive things better.

Non-polarized glasses reduce the intensity of sunlight. They also protect your eyes from UV rays, but they won’t reduce reflection from snow, water, or glass.

You need as much light as possible when driving at night. Polarized glasses have filters that prevent light from hitting your eyes. It creates a dimmer view, and this could make it more likely that you’ll get in an accident.

They are ideal to use every day. They offer a better view while eliminating glare from the sun. However, don’t wear them when looking at LED screens or driving at night.

Spending time outdoors is always refreshing and necessary for a healthy lifestyle. Enjoying the sun is one thing, but taking care of your eyes while outside is essential. That’s where consistent eye exams and choosing the right sunglasses come in.

Polarized sunglasses are a great option for you if you love spending time outdoors. Polarized lenses can help reduce glare and provide clarity when you’re working outdoors in a high-glare environment surrounded by water or snow.

Polarized lenses prevent light glare from hitting you directly in your eyes. By coating polarized lenses with a particular chemical, they block some of that light and glare as it passes through them. Polarized lenses act as a filter for what reflects into your eyes.

Things may look a little darker than usual when you’re wearing grey polarized sunglasses. Still, the trade-off and difference from regular sunglasses is the added protection for your eyes from the sun’s rays and glare.

Polarized lenses are darkened and perfect for high-glare activities and spending time outdoors. However, they’re not ideal for reading glasses and other activities.

Polarized lenses and UV-protected lenses aren’t the same—it’s important to note that polarized lenses don’t provide UV protection unless otherwise specified.

While not offering more UV protection, polarized lenses do provide a contrast that can reduce glare and make outdoor activities safer and easier on your eyes.

Polarized sunglasses perform a specialized function and are for people who are spending a lot of time outdoors and want to reduce bright reflection and unwanted glare. Polarized sunglasses are a great option for you if you’re often in bright situations and need proper eye protection.

Polarized lenses aren’t designed to protect you from directly staring at the sun. You should always take precautions to protect your eyes from harmful UV light.

Protecting your eyes is an ongoing process—anything you can find to assist and make your day-to-day life as comfortable as possible is essential. Polarized lenses are specialized and can combat some of the discomforts that glare can bring. Book an appointment with your optometrist today to learn more about polarized sunglasses and get your own pair.

Light waves from the sun, or other artificial light such as a light bulb, vibrate and radiate outward in all directions. Polarized filters are most commonly made of a chemical film applied to a transparent plastic or glass surface. The chemical compound used will typically be composed of molecules that naturally align in parallel relation to one another. When applied uniformly to the lens, the molecules create a microscopic filter that absorbs any light matching their alignment.

When light strikes a surface, the reflected waves are polarized to match the angle of that surface. So, a highly reflective horizontal surface, such as a lake, will produce a lot of horizontally polarized light which causes a very intense and sometimes dangerous brightness that results in glare and reduces visibility. Therefore, thepolarized lenses in sunglasses are fixed at an angle that only allows vertically polarized light to enter. The horizontal light that creates the effect of glare is absorbed and nullified by the chemical film on polarized lenses.

The first polarizing film was developed byEdward H. Land in 1929. The technology he used as explained above was simple, yet effective. Lenses are treated with chemicals that only allow in light that travels in a vertical motion. As glare travels horizontally, it can’t make it past the polarized lens.

Polarized sunglasses do not look very different than regularnon-polarized sunglasses. As a matter of fact, some companies that produce lower-quality sunglasses market them as polarized sunglasses when they are not. So you need to have a way to tell the difference between polarized vs non polarized sunglasses. Here are some ways to determine if your sunglasses are polarized or not:

Checking the label or sticker: Obviously, the simplest way to know if your sunglasses are polarized is to check the product description (if you bought online), the tag attached to the glasses or box they came in, and the sticker on the glasses. Since most people consider polarized sunglasses are somewhat superior to regular ones, the manufacturers would most likely include this advantageous feature in order to get their products to sell faster. If it doesn’t state on the sticker, the box or the product listing online that it is polarized, then it most likely isn’t. Bear in mind though, that not all companies are genuine in stating the real contents of their products, so this might not be the most effective method to affirm the polarization of your sunglasses. However, if the company is a reputable one that you trust, you can take their word for it.

Comparing two pairs: Another way to determine the polarization of your sunglasses is by comparing it with a pair that you know for sure is polarized. This can be a pair that you borrowed from a friend, an old pair you have at home or a polarized pair off the shelf in a store. When you hold both pairs of sunglasses up, one in front of the other, you should be able to see through them. However, if you tilt or rotate one of the pairs to a 90 degrees angle, the lens should darken or black out if they are both polarized. If it is clear when rotated and you can see the polarized pair behind the pair in question, then the new pair is not polarized.

Looking at water or reflective surfaces: To determine whether your sunglasses are polarized or not, simply put on your sunglasses and find a surface that light bounces off of. This could be a shiny flat reflective surface like car windshield or windows or glass tabletops and it could be a shallow body of water like a lake or river in broad daylight. You’ll know your sunglasses are polarized if you can see past the glare on the particular surface you’re looking at or if you can see right into the body of water below. If you can’t, you have just a regular tinted pair of sunglasses.

Looking at a computer or LCD screen: For best results, try to make the screen as white as possible. If you’re using your computer, pull up a blank MS word document and if you’re using your mobile device for the experiment, try Google’s homepage. To use this method, just put on your sunglasses or hold it up against the screen. Then tilt your head or the sunglasses at a 60-degree angle and if the screen dims or darkens, you have polarized sunglasses. The science behind this is that most computer screens have the same anti-glare protection as polarized sunglasses do. As a result, the lens and screen end up counteracting each other by working in opposite directions and you’ll get a dark or blacked-out image on the screen.

Using test cards: Another unconventional way to test for polarized sunglasses is by using polarization test cards. A lot of companies that sell polarized sunglasses also sell these test cards. When the cards are viewed through a polarized lens, an image will appear on the card. Meanwhile, if they’re viewed with regular sunglasses, they’ll appear blank.

Everyone should own a pair of polarized sunglasses. They are the premier choice for outdoor enthusiasts, and those who live their lives on the water- fishing, boating etc and anyone else who demands the clearest vision from their sunglasses. The reason they’re in such high demand is mainly because of their glare-reducing benefits. Regular tinted sunglasses do not block glare, so make sure you don’t waste your precious coins on them.Using the guide in this article when next time you want to purchase polarized sunglasses will ensure you buy genuinely polarized ones, and get good value for your money.

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?

Wouldn’t it simplify things if you could just wear your everyday Terra firma shades up into the wild blue yonder?  No more remembering to pack a separate pair of sunglasses and to switch to them for flight.

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.

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.

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.
