On the cutting edge between sport and lifestyle, Oakley Valve is for active lives that demand both performance and pace-setting style. Stress resistant O Matter frame material makes it lightweight while Unobtainium components increase grip with perspiration, and the comfortable Three-Point Fit keeps the lenses precisely aligned for the clarity of High Definition Optics. If you're looking for a go-anywhere, do-anything sunglass that blends street smarts with brilliant innovation, this is it. In fact, the optical performance meets ANSI Z87.1 standards (like premium pure-sport sunglasses), and this eyewear even has impact resistance that meets ANSI Z80.3 basic impact standards. The lens curvature opens your peripheral view while our pure Plutonite lens material filters out every ray of ultraviolet light, not just UVA and UVB.
