Polarized Lenses
These lenses have become very popular in the sports world. They cut unwanted reflected glare from sunlight bouncing off water, metallic surfaces, pavement, or snow. For example, sunglasses with polarized lenses are popular and useful for fishing, driving, skiing, and other related activities. Polarization has nothing to do with UV light abosrption, but many polarized lenses are now made with a UV-blocking substance.
