When sports pros like Ian Poulter, Annika Sorenstam, Peter Reid and Sam Stosur demanded optical performance beyond the limits of what was possible, Oakley set out to create the most technically advanced eyewear ever invented. Oakleys High Definition Optics (HDO) hones vision with razor sharpness, and with XYZ Optics, the lens clarity extends to the far edge of contours that maximize peripheral view and side protection. UV filtering is 100%, and performance meets ANSI Z87.1 standards for optical clarity and impact resistance. The frame is made of durable O Matter with Unobtainium components that increase grip with sweat and take comfort to a new level. Designed to complement Asian facial anatomy in both fit and comfort.
