Description of Oakley Belong Sunglasses - Lavendar Tortoise / G40 Black Gradient - Women's Inspired by Oakley women who live by their own rules, BELONG™ writes its own stylebook. Sculptural metal detailing adds a touch of magnificence without being showy, and smooth contours of lightweight acetate keep it anchored in feminine charm. A graceful silhouette highlights a perfect Three-Point Fit that gives comfort an entirely new definition. Oakley curved the optics to open peripheral view and block the powerful rays of UV that can lead to vision problems and damaged skin around the eyes. Oakley's pure PLUTONITE® lenses filter out every searing wavelength that tries to get through, and their impact resistance meets ANSI Z80.3 standards. BELONG™ sunglasses also come with the clarity of HIGH DEFINITION OPTICS® (HDO®) and the convenience of an included eyewear case, our exclusive women’s design. Options include IRIDIUM® lens coating for balanced light transmission, gradient lens shading, and Oakley prescription lenses. This frame is also available with Oakley polarized lenses.
