The Belong Sunglasses from Oakley are part of the Oakley High Definition Optics (HDO) line. Oakley combines patented optics and Plutonite lens material that provides 100% UV filtering and unsurpassed impact protection.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. 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. The Belong also meets ANSI Z80.3 impact standards.
