The Radar Range Polarized features Oakley RADAR, a milestone in performance technology. The lens in this polarized edition of RADAR is engineered to block the blinding rays of glare that are magnified by flat surfaces such as snow, water and pavement. Oakley uses a liquid infusion process to eliminate the haze and distortion found with ordinary polarized lenses. RADAR features Oakley Hydrophobic, a permanent lens coating that prevents rain and sweat from building up on the lens. It also repels skin oils and other contaminates, so the lens is smudge resistant and easy to keep clean. It even eliminates static electricity, so dirt and dust particles won't cling. RADAR lets you change lenses in seconds to optimize vision in any sport environment. Many performance lens colors are available, and all lenses feature the unbeatable clarity of Oakley's HIGH DEFINITION OPTICS (HDO). RADAR is made of lightweight O MATTER for all-day comfort.
