Polarized lens sunglasses have been protecting the eyes of sunglasses wearers since 1936, when frames with those lenses first hit the market. So what are "Polarized Lenses" and what's their function, you ask? Polarized-lensed sunglasses reduce the sun glare that's reflected from some angles off shiny non-metallic surfaces such as water or windows. They're the ideal choice of eyewear for fisherman, mountain climbers, hikers, beach-goers, or those who are just lying next to the pool. You'll find many models and styles available for men, women, and children with polarized lenses. Ray-Ban, Tom Ford, Bolle, and Oakley, among many others in our stock, are the brands you love and trust, and they all feature lenses that also offer 100% protection from harmful UVA/UVB rays from the sun. Think of them as a sun blocker for your eyes. For the best protection, most experts agree that models reflecting or filtering 99 to 100% of UVA and UVB light, better known by their label UV400, is best.
