Information about Polarized Sunglasses

Sunglasses are commonly known as colored glasses which are used to block sunlight and ultraviolet light.
Polarized sunglasses can anti-ultraviolet light and reduce the intensity of light, but also can effectively filter out glare. The lens color is brown, grey and dark green.
