What Are Polarized Sunglasses?

Standard sunglasses are designed to protect your eyes from bright light and in most cases, offer UV protection. But the standard sunglasses can’t reduce glare. However, polarized sunglasses are designed to reduce glare from light reflecting surfaces like water, glass or snow, and also prevent your eyes from damage from harmful UV rays.

The polarized sunglasses look exactly the same as the standard sunglasses, but their lenses are featured a polarizing film that can change the way light reaches your eyes.

How can you tell the polarized sunglasses and non-polarized sunglasses? Here is a simple way. You can hold the sunglasses in front of a reflective surface and look through one of the lenses. Then slowly rotate the sunglasses 90 degrees to the right or left. If the glare reduces, the sunglasses are polarized.
