For people who are often near water, polarized sunglasses is never far away. And that is not surprising considering polarized lenses help to block glare from light reflection off the water surface better than any other type of sunglass. But polarized sunglasses isn’t just for those who get in water often, it is also helpful when walking under sunny conditions and for driving, since it reduces glare causing reflection from surfaces such as the hoods of vehicles and light-colored pavements. In this article, we’ll explore what polarized sunglasses are and how to get one.
What Are Polarized Sunglasses?
Polarized sunglasses are made to reduce the glare that produced on flat surfaces like water, snow, or glass. Glare changes the true colors of an object, reduces visual clarity and contrast, causing eye strain and ocular fatigue. Polarized lenses have special filters that absorb horizontal light reflecting from various objects in the surroundings. These sunglasses improve vision and offer superior protection for the eyes, which is essential, especially when driving or doing certain sports.
How To Tell If Sunglasses Are Polarized?
You can determine if your current sunglasses have been polarized in several ways. These tips will help you save money and your eyesight and prevent macular degeneration.
- Perform a computer polarized test
This is very easy as you just need to wear your sunglasses and get on your PC. While looking at your computer screen, you can tell if your sunglasses are polarized. The glare-reducing technology of computer screens are the same with polarized lenses. When looking at a computer monitor, move your glasses sideways and if parts of the screen become blank or dark, you are using polarized glasses. You’ll get the same with LCD display screens as well.
- Look at Water
One major benefit of wearing polarized lenses is to cut down on glare, like the kind you get when the sun is reflecting off water. With a polarized sunglass, you won’t just see the surface of the water, but you’ll be able to look through into the water below, and maybe catch a fish swimming past.
- Compare two pairs
If you have a friend who uses polarized sunglasses, all you need to do is compare your with theirs. First, hold up your glasses and their glasses at the same time, and look through both of them at once. Then rotate one pair about 60 degrees. If both glasses are polarized, the are that overlaps becomes darker as they filter out excess light. However, there won’t be any difference if your pair is not polarized.
- Check the Label
A sticker can be found on the lenses of most new polarized sunglasses that states that the glasses are polarized. But some companies take this even further and mark their polarized sunglasses permanently. Some etch the word “polarized” at the bottom of the left lens.
How Do Polarized Sunglasses Work?
Polarized sunglasses have lenses that come in many colors, depending on the material the lens was made from. The best polarization comes from darker colors. Sunlight can be absorbed or reflected in many different directions. Sunlight that bounces off horizontal surfaces like water, land, or the hood a car typically reflects back in the same horizontal direction.
This reflection produces a source of glare that not only creates visual glare, which can potentially create a temporarily blinding glare. This can be very dangerous, especially when driving.
Polarized lenses have a laminated filter that lets only vertically oriented light to pass through. The horizontally oriented light is blocked so that glare is almost eliminated. Gray and brown are the most common colors of polarized lenses. However, many manufactures use other popular colors like green, yellow, or black.

UV radiation increases the possibility of developing cataracts, which can damage the retina and cause macula degeneration. Polarized lenses help to filter the UVA and UVB rays from the sin, providing a better eye protection and significantly reducing the risks of sun exposure.

Your eyes tend to see over-exposed objects, when a polarized sunglasses is not worn. Polarized lenses contrasts colors better even with intense brightness, and this is due to the fact that it filters a horizontal light patterns are filtered away.
