These lenses give you the razor-sharp clarity and unbeatable performance of Oakley's HIGH DEFINITION OPTICS® (HDO®). Two lens shapes are available, and you can even get them with Oakley technology that produces the best polarized lenses on the planet. For protection, Oakley's PLUTONITE® lens material filters out 100% of all UV, not just UVA and UVB. And when it comes to high-mass and high-velocity impact, the installed lenses meet all protection standards of the American National Standards Institute. So forget about lugging around extra pairs of shades for when light changes. With HALF JACKET and accessory lens kits, you'll be ready for anything.
