polarized sunglasses lcd screen quotation

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

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.”

In the previous article, we discussed “Are Night Driving Glasses Safe?”. In this article, let’s talk about “How to see phone screen with polarized sunglasses”.

Many drivers have the habit of wearing sunglasses. After all, direct sunlight on the eyes not only damages the eyes, but also affects driving safety. But many drivers say that wearing sunglasses can actually make people uncomfortable, such as not being able to see the phone screen and navigation screen. Why do polarized sunglasses make phone look weird?

Polarized sunglasses may make it easier and more comfortable to see things outdoors, but wearing them when trying to see an LCD screen can sometimes leave your eyes in the dark.

Most LCDs (such as your smartphones and tablets) use polarizing filters to help you see the screen clearly in bright sunlight. But the same is true for polarized sunglasses, which means that the two essentially cancel each other out, causing your LCD screen to look dark or completely black when you look at it.

Polarized lenses are lenses that only allow light in a certain polarization direction in natural light to pass through. Because of its filtering effect, things will darken when you wear it. In order to filter the sun shining on the water, land or snow in equal directions, a special vertical coating is added to the lens, which is called a polarized lens.(https://www.koalaeye.com/collections/polarized-sunglasses)

The special effect of the polarized lens is to effectively eliminate and filter the scattered light in the beam, so that the light can be input to the visual image of the eye on the transmission axis of the normal track, so that the visual field is clear and natural. Similar to the principle of blinds, the light is adjusted to the same direction and enters the room, which naturally makes the scene look soft and not dazzling.

LCD screens and sunglasses often contain polarizing filters to make it easier to see clearly, especially in bright sunlight. The polarizer has the function of shielding and transmitting the incident light, allowing one type of vertical light or horizontal light to pass through and the other to be shielded. What often happens is that your polarized sunglasses only allow light to pass through vertically, thus functioning. At the same time, your phone screen will emit horizontal vibration light while blocking vertical light. Your lens and screen will eventually cancel each other out by working in opposite directions. As a result, you will end up seeing a dark or blackened image.

Therefore, due to the combined action of the polarizing lens and the polarizing plate, after wearing sunglasses with polarized lenses, the screen of the mobile phone cannot be seen. In fact, these two things have the function of filtering the direction of light, so when they meet together and the shielding and transparent parts coincide with each other, you will not be able to see the phone screen.

The solution is simple. Rotate the tablet or phone screen 90 degrees. This technique is usually effective because it locates the polarizing filter of the screen so that they can block light waves traveling in the same direction as polarized sunglasses and let light pass through.

Newer smartphones and computer screens have found a solution to this problem, but when you wear polarized sunglasses with an older model screen, you may still notice that the screen is dark.

In some cases, you may need to view the LCD on a dashboard that cannot be rotated. This may be true for crew members and pilots who must be able to read instruments quickly and accurately to ensure their safety. Therefore, in these situations, you should avoid wearing polarized sunglasses.

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

Polarized lenses are made to reduce the glare of light from objects around you, particularly outdoors. This is why they are only found in sunglasses, either prescription or non-prescription.

Light is made up of waves that are oriented in all directions. A polarized lens has a laminated filter that only allows light from one angle to enter, usually vertically oriented light. With horizontal light waves blocked, the glare is diminished or completely gone.

Polarized lenses are made when organic dyes and metallic oxide pigments are mixed into the lens material, making them part of the lens rather than just a coating. Care is taken to keep color distortion at bay, making gray the most popular color of polarized lens. Brown and amber are other common colors but while many other tints are available they may cause too much color distortion.

Polarized lenses are highly recommended for people who spend an abundance of their time outside.Polarized lenses reduce glare, or bright light reflected from surrounding objects. This is particularly dangerous when driving or walking near vehicular traffic since light glaring into a driver’s eyes can cause an accident.

Polarized lenses provide protection from UV rays although the protection may not be significant depending on the construction and quality of the lens.

Polarized lenses tend to make LCD screens difficult to read, often causing the text to disappear completely. This has become more problematic in recent years due to the proliferation of LCD screens. For most it is a minor inconvenience but for machine operators who must be able to read those screens, it can be dangerous. However, BluTech outdoor lenses are polarized and still allow you to see those LCD screens!

Also, as noted above, while polarized lenses can protect your eyes from UV light, the amount of protection varies. Be sure to check labeling for specific UV protection claims.

While polarized lenses may seem to be a great tool for skiers, they can actually compromise the light contrast that alerts the skier to specific conditions such as being able to distinguish between ice and snow, or the presence and shape of moguls. However, polarized lenses are excellent for water sports where glare from the water can be a nuisance or a nightmare.

The next time you need replacement lenses, don’t be surprised if anti-reflective treatment is suggested by your eye care professional. And if you love or work in the outdoors, in bright sunshine or even hazy conditions, polarized lenses can help you see better and protect your eyes.

I"ve got these Holbrooks Prizm Black Polarized pair and something weird goes on when I put them on and I watch my LCD monitor screens (I know this is the normal usecase, but bear with me).

Also, if I change my viewing angle towards the screens, at direct angles the screen is displayed more dark and at side angles it"s displayed with more light.
