What are polarized sunglasses?
Most of the glare that occurs outdoors comes from flat surfaces like water, roads, metal, and glass. When the sun hits a horizontal surface like water, it creates horizontal light waves. Polarized lenses are coated with a chemical film that lets in vertical light waves and filters out horizontal light waves. This eliminates most of the reflections that cause bright outdoor glare.
Why are polarized sunglasses used?
Polarized sunglasses are designed to protect the eyes from harmful UV rays and enhance vision in even the brightest outdoor conditions. They are meant to be used in situations where it is necessary to see clearly and filter out dangerous glare.
Polarized eyewear can be beneficial to everyone from fishermen to athletes, joggers, bikers, and boaters. People who are highly sensitive to light can benefit from wearing polarized glasses indoors and outdoors. Children in particular can benefit from the UV protection afforded by polarized lenses.
