   What are polarized sunglasses?

   • Polarized sunglasses are eyewear made with special lenses that reduce reflected glare from surfaces such as water, snow, and glass. Polarized sunglasses can be especially useful in situations where you need to see clearly and avoid hazards. Despite what some people think, polarized lenses do not protect against ultraviolet (UV) light from the sun.

   How do Polarizing sunglasses work?

   • Horizontal surfaces in the environment, such as the asphalt of a street or the surface of a lake, reflect light that is vibrating horizontally. Polarizing sunglasses absorb this horizontally oriented glare. If you tilt your head sideways, this horizontally oriented glare passes through the glasses, making the surface look brighter.
