As we mentioned earlier, they are also known as “anti-glare” glasses; due to their property of reducing the glare of the light. It automatically reduces the pressure on your eyes, keeping them and your eyesight safe. It is also beneficial in extreme weather conditions, such as a scorching sunny day or snowing outside.

Adding on to it, these sunglasses help reflect direct sunlight into your eyes, which means protecting against harmful UV radiations as well. Also, polarized sunglasses help filter vertically polarized light, and ambient light, which increases your vision in bright light waves without adding to your eye strain. Also, polarized lenses neglect horizontal light and allow vertical light only.

The polarized sunglasses are primarily similar to the prices of regular sunglasses, which means you won't have to buy the very-expensive options to get the polarized ones.

How to Tell If Your Sunglasses Are Polarized or Not?

Now, you are stuck when you have ordered online sunglasses without making sure that the sunglasses are polarized or not. But you don't have to be anymore!

We are here with multiple tests you might do at home to check whether you have bought a polarized sunglass. Therefore, worry no more and try the following methods to see if you can get the correct answer.

Method # 1: Look at the label or sticker of the product

label or sticker

This has to be the first and the easiest method, as you literally have to do nothing else than look at the sticker. If your sunglasses are polarized, it has to be mentioned on the label. This is because every famous/competitive company has to post product descriptions on the label as an obligation. Thus, you might see the mention of being polarized on the label if your sunglasses are one of them. If you don't, then we believe you got the other option.

Method # 2: Try reflecting surfaces or water

reflecting surfaces or water

Another method to determine whether you have polarized glasses is to wear your sunglasses to a swimming pool or a beach. You will have to see if the bright light or reflected light is bounced off by the sunglasses. Polarized sunglasses would reduce the glare before reaching your eyes, while regular sunglasses wouldn't. If you feel a sudden sharp light in your eyes, you have non-polarized sunglasses. Nevertheless, the test might help you clearly confirm whether you should wear your sunglasses in bright sunlight.

Method # 3: Try using polarized lens test cards

polarized test cards

You might not know, but numerous companies are now selling polarized test cards worldwide to help customers tests their sunglasses. They claim that when you look through the cards with any polarized sunglasses, you will see an image on them. Conversely, if you are wearing a regular pair of sunglasses, you won't be able to see the image, and the card would instead appear blank. This is a tried-and-tested method to determine the polarized glasses on your sunglasses.

Method # 4: Work on a Computer Screen or LCD screen

Computer Screen or LCD screen

You would need either a computer or a TV screen for this method. In addition, try keeping the screen white or bright as much as possible. For example, while working on a computer or laptop, open up a word document or a blank notepad document. Afterward, move your head in a 60-degree direction, tilted while looking at the screen. If in return, you see a darkened or black screen, you are wearing polarized lenses. The logic behind this is that computer screens also end up having the same anti-glare properties as polarized sunglass; therefore, both cancel out each other's effect resulting in a black screen. If the results are otherwise, you know what that means!

In any case, it is only sometimes possible to check your sunglasses outside your home at all times; therefore, we have also listed out some tests you could do at home. Please keep reading to know about them!

The Best Sunglasses Polarized Test for Pairs

Best Sunglasses Polarized Test

If you still need packaging or labels on your sunglasses now, it has been days or months since you got them. But, suddenly, you want to check whether they are polarized; you are not alone. Hence, we have some easy hacks for you as well. Without you needing to step outside the house, the following are some of the best tests for your sunglasses:

Test # 1: When you have a single pair of sunglasses

If you have no other glasses to compare to, test with your single pair. For that, wear your sunglasses and look at any bright surface. This reflective surface could be water, glass, a digital screen (e.g. a mobile device), or anything with sharp light vision. Tilt your head at 60 degrees again, and if your image starts getting brighter, then you probably do not have a polarized pair. On the contrary, if the image receives lightened or darkened while tilting your head, the sunglasses are a polarized pair.

Test # 2: Compare your sunglasses with another pair

The second method we recommend is comparing your sunglasses with a polarized one, whether you buy it or get your friends. Compare the light reflection properties for both sunglasses; in different locations. Wear the sunglasses outside in bright light and dark areas and compare what you see. In the end, you might also rotate the sunglasses. If on turning at a 90-degree angle, the lens blackens out, it means both sunglasses are polarized. On the other hand, if on rotation, if one of them gives a clear vision and the other borrowed pair is at the back, it means your new sunglasses are, unfortunately, non-polarized.
