Polarized Sunglasses

Polarized Sunglasses 

The idea behind this is innovation is simple. Polarized sunglasses have small filters that have openings for verticle light only. This means that only the light rays coming towards the eye directly will be allowed through the lens. All the horizontal light will be reduced, which can be very helpful in situations requiring high focus such as while piloting an aeroplane or a boat.

The initial idea was in fact adopted by Ray-Ban to create better glasses for airforce pilots. The level of glare in the sky can be too much to take, even with goggles. The polarized sunglasses called the Aviators created by Ray-Ban were the go-to glasses for such situations.

Today a lot of other sunglasses brands use polarized lenses. It has been a useful feature aside from the tactile importance, it is widely used in the sporting world as well as by regular users who may have a sensitivity to light.

Keep in mind, polarized lenses do not mean they protect you from UV-rays, that is a separate feature with sunglasses.
