polarized sunglasses lcd screen manufacturer

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 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

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.

The most frequently chatted regarding disadvantage of polarized lenses is that they can make it tough to look at LCD displays. While putting on polarized lenses, the lenses minimize the quantity of light your eyes process from an LCD display. In specific conditions your phone display may be noticeable when taking a look at it at a 90 degree angle, transferring to various angles can make the display go away totally.

The therapies in auto glass can additionally be slightly extra obvious while wearing polarized lenses, creating some small distractions while driving. Upgrade to Polarized Lenses At Revant, we concentrate on making polarized replacement lenses for any kind of brand name of sunglasses. If you have an old pair of non-polarized sunglasses that need to be refreshed or updated, we can assist.

That"s since the light in the skies is polarized. Revolve the polarizer as well as notice that at one orientation of the polarizer, the surface reflections are greatly decreased and you can see below the surface area of the water.

Polarized sunglasses work by removing particular frequencies and positionings of light, such as ultra-violet, which is damaging to human eyes. In order to polarize a material for light, etches of scratches have to be microscopically be taken into the product, so that just the light waves that are lined up with the scrapes can go through.

Drive with Self-confidence If you invest the day behind the wheel of an automobile or vehicle, polarized lenses need to be a must-have in your sunglasses. Polarized lenses can lower the glow from the roadway itself or the light reflected as glare off of your vehicle or vehicle. Polarized sunglasses provide crisp, clear vision without wearing down your eyes, which is crucial for any person who spends the day driving.

We"re here to clarify what polarized sunglasses are as well as exactly how they function. Table of Component, Watch Sunglass Rob briefly discuss what polarized sunglasses are, or read on to learn a lot more.

To make a polarized lens, sunglass makers use layered movie to the lens surface area in vertical stripes that enable upright, yet not straight, waves to pass through. While a darker lens decreases polarized glow, it can not obtain rid of it.

Putting two polarized filters over each other causes them to terminate each other out. In the Sport, Rx display room, we have a special display where the video clip having fun on it is just visible with polarized lenses. Unfortunately, this trick just functions if you"re checking out the display in person. If you try this in your home, the white screen will certainly still just be a white screen.

Below are the most usual sporting activities individuals ask us about, yet if you"re still not exactly sure, do not hesitate to contact us! Fishing and Sailing, When you do sports on or near water, such as angling or sailing, you can"t obtain by without polarized lenses. Water shows 100% of UV light right back at your eyes, making the surface area almost impossible to see without polarization.

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.

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.

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.”

Ultraviolet rays from the sun are incredibly damaging to our eyes, so proper eye protection is important at any time of year. However, choosing the right sunglasses is no easy task with so many choices available.

Glare has the potential to create very dangerous situations, especially when driving. Sunlight that is bouncing off horizontal surfaces, i.e. the road, can be vastly reduced with the use of polarized sunglasses.

Sunglasses are generally more expensive than regular tinted lenses. This additional investment is worth it for the majority of people who want to optimize visual comfort.

So, in conclusion, although we have talked a great deal about polarized lenses, to ensure we have a good understanding of what that is we can, therefore, make an informed decision of which root to take. Most tinted sunglasses do have the UVA/UVB protection in the lenses that is required to meet British Standards but they don’t provide the same quality of visual comfort we get from polarizing. If in any doubt… ask your optometrist what they wear!

• Perform highly diversified duties to install and maintain electrical apparatus on production machines and any other facility equipment (Screen Print, Punch Press, Steel Rule Die, Automated Machines, Turret, Laser Cutting Machines, etc.).

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.

Have you ever tried reading a message on your phone while wearing sunglasses? That annoying checkerboard pattern is the result of polarized light. Just like you rely on your cellphone for everyday use, pilots rely on their LCD flight monitors for a safe and successful flight. With polarized glasses, these displays are difficult if not impossible to read. So what exactly does polarized light mean?

Light is made up of waves going in a specific directional field. Since the sun is not polarized, the directions are scattered with no uniform trajectory. When light is reflected off of a surface, such as water, it becomes polarized, meaning all the light is in one directional field. Polarized sunglasses have a coating called a polarizer, which filters light into a specific direction before it reaches your eye.

So why aren"t all glasses polarized if they reduce glare and increase visibility? LCD screens found on smartphones, televisions and many monitors are also constructed with polarized filters, and viewing these through polarized sunglasses creates distortion. This means that the light emitted off of the LCD screen is polarized and emitted out horizontally. Consequently, LCD screens are often difficult or impossible to read while wearing polarized glasses, which can be problematic.

This is why pilots who depend on their LCD monitors for their primary flying instruments, such as their navigation display and other essential gauges, would not be able to see these displays clearly with polarized lenses. Additionally, cockpit windows are often partially polarized. When polarized sunglasses are worn, dark oily patches are commonly seen when looking through the airplane"s window, severely reducing visibility and posing safety risks.

Method Seven nonpolarized sunglasses have an anti-glare coating that allows for a crisp LCD display without obstructive sun glare. This will enable you to view your iPhone, GPS, or instrument panel with perfect clarity while safeguarding your eyes from harmful glare. Polarized sunglasses may offer adequate protection at the beach, but if you"re depending on your eyes to see your instrument panel in-flight, nonpolarized lenses are a safer option with better clarity.

As we all know, polarized sunglasses have many advantages. They can protect your eyes from glare, and help your eyes stay health. However, polarized sunglasses also have some drawbacks. If you want know more about polarized sunglasses, this is the article you should read.

Polarized sunglasses are a special type of eyewear that helps to reduce glare from sunlight. Glare is caused by light reflecting off of surfaces such as water or pavement. When this light enters the eye, it can cause discomfort and even temporary blindness. Polarized lenses work by absorbing horizontal light waves, which eliminates glare and makes it easier to see. In addition to reducing glare, polarized lenses also provide 100% protection from harmful UV rays.

While polarized sunglasses are great for reducing glare, they can also interfere with your ability to see fine detail. This is because polarized lenses block out light that is coming from all directions, including light that is reflected off of surfaces. As a result, polarized sunglasses can make it difficult to see things like small prints or intricate designs. If you need to see fine detail, it is best to remove your polarized sunglasses.

Polarized Sunglasses offer protection from the sun’s harmful rays. But the downside to these types is you may not see properly when wearing them because your eyesight could come into conflict with what"s in front or behind where one looks through the lens at an object off-screen (i e., near misses).

Polarized lenses don’t block UVA or UVB rays. Some polarized lenses also offer UVA and UVB protection, but not all. People in areas with high levels of sunlight exposure may need pay attention to this problem.

LCD displays, which can be found in a cockpit, emit polarized light. Therefore, polarized sunglasses reduce the ability to read those LCD displays. A pilot with polarized sunglasses on could fail to see a shimmer of glare given off by another aircraft’s windscreen. This may also be an issue in some sports where watching the score or stats on large LCD screens is vital.

The protective effect of these sunglasses is usually achieved by adding a layer of COATING on the surface of the lenses. And this layer of coating may gradually be worn out under the influence of time and lose its function.

It is no wonder that polarized sunglasses cost more than regular ones. Although polarized sunglasses have many outstanding advantages, but for the buyers who only want to play the role of outdoor protection, the high price may seem very unreasonable. And with a little carelessness, if the purchase does not suit their style, such a large amount of money will indeed be very heartbreaking.

These lenses do not filter the light completely, which results in the penetration of harmful sunlight through the lenses. The constant disruption of light caused by the polarized lens can also cause a strain on the eyes when using tech devices. The coating of the polarized lenses makes it difficult, and induces a strain on the nerves of the eyes, which cause severe headaches.

Polarized lenses are very popular among sports lovers, and are considered a ‘must-have’ for many fishermen and runners. Polarized lenses for sports glasses give you extra protection compared to standard sports eyewear. Polarized lenses reduce glare on reflective surfaces - like water or the road. In theory, this enables you to see objects and your surroundings clearer, sharper and unhindered. It allows fishermen to see straight through the water which is great for shallow water fishing.

Despite many benefits, polarized lenses for sports have some limitations too: Regretfully, polarized lenses can, in some cases, distort vision. Like when looking through a car window or windshield, one may see strange patterns created due to glass tempering. Similarly, in some specific instances, they may distort vision by showing unusual patterns (on the road) when biking or driving in harsh sunlight. What’s more, by taking away glare, polarized lenses also take away the ability of many sports people to correctly distinguish depth and contrast. In golf, players need the glare from the blades of grass to see slopes and judge the greens better.

Driving sunglasses with polarized lenses can eliminate glare and will help keep your vision sharp while operating a motor vehicle, bicycle, or boat in difficult lighting conditions. However, as mentioned above, polarized sunglasses may distort your vision, and when you need to pay special attention to landmarks, wearing polarized sunglasses may require caution.

Now then, why this happens is because of the way that 3rd party screens are designed, all devices with LCD screens have a polarization filter with in them, why this is is because of the way that light works. With out them you wouldn"t be able to see the screen at all, it would look black blue white or fuzzy. Polarization works by taking all the rays of light and refracting them to a certain direction. It works well in sun glasses because rather than dimming the light with a dark glass, it refracts away most of the light coming towards your eyes and dims the ones that do come through. However, when your looking at already polarized light with them, if the filters are not polarizing to the same direction of light it will filter out all of the light, hence why it works in landscape. Adding the tempered glass on top refracts the light again in a different direction which is why that fixes the issue. Apple"s polarization filters on their screens are different than 3rd party screens, though the difference is so slight, the only time you would ever notice this is with the polarized lenses. Apple and "apple verified repair shops" (which are essentially smaller non apple owned apple stores from what I can tell) are the only places in the world that can get apple original screens, all other repair shops are left to find suppliers of 3rd party screens, eBay, or making their own form 3rd party parts.

So in conclusion, 3rd party screens are made slightly differently, which causes a small issue that ,however annoying, can be fixed fairly easily and cheaply if you look online.

Edit: all screens come from china including apple original screens and all are maid fairly cheaply (screens can cost apple and 3rd party suppliers sometimes less than $10 to make depending on the model) they charge for the demand of the product and the time spent to make it and obviously to make a profit because that is the goal of any company and most individuals, money is a big part of every society.
