The ultimate in sport performance eyewear, the Oakley Radarlock Path Sunglasses feature a lightweight and durable O-Matter frame that's comfortable to wear all day long, and they included Unobtanium on the earsocks and nosepads that increase their grip with perspiration to keep your glasses in place even as you start to sweat. The revolutionary Prizm lenses provide unprecedented control of light transmission that maximizes contrast and enhances visibility, while the Plutonite lens material filters 100% of all UVA, UVB, UVC and harmful blue light up to 400nm to protect your eyes from the sun's damaging rays. Plus, their semi-rimless design extends your lower field of view and gives them that fun, sporty look you want!
