High Definition Optics (HDO(R) combines patented optics and PLUTONITE(R) lens material that provides 100% UV filtering and unsurpassed impact protection in order to create the Oakley Gascan Sunglasses. Two lenses are cut from the curve of a single lens shield, then mounted in the frame to maintain the original, continuous contour. The look is so unique, Oakley customized its corporate logo just for these sunglasses. Lightweight O MATTER(R) frame material offers premium comfort. Peripheral vision is maximized by XYZ OPTICS(R), an innovation that maintains visual clarity at all angles of view. Impact protection meets ANSI Z87.1 standards, and Oakley's Three-Point Fit retains the lenses in precise optical alignment. True metal icons sign this Oakley original.
