The latest evolution of an Oakley favorite, the Square Wire features Oakley's coveted HIGH DEFINITION OPTICS® (HDO®) for unbeatable clarity and protection. Lightweight C-5™ alloy is the reason why the Oakley Square Wire sunglasses feel comfortable all day. Temple sleeves of soft UNOBTAINIUM® increase grip with sweat while spring hinges balance the fit. If you’re focused on the styling, you may not notice that it meets all ANSI Z87.1 standards for optical performance and impact resistance. But the science behind all that technology is also the art that curves the lenses back, achieving a definitive look that just happens to maximize your peripheral view.
