Our first dual-lens sunglasses with interchangeable lenses, this chameleon lets you adapt instantly to any light condition. When the sun fades or flares, switch to a new set of optional lenses and change your entire point of view. Or just enjoy the freedom to customize your look instantly. Accented with true metal icons, the lightweight O Matter® frame includes Unobtainium® earsocks and grip anchors. The open-edge design extends your vertical field of vision, and each set of optional lenses retains the peripheral clarity of XYZ Optics®. That’s just one of the patented innovations that give High Definition Optics® (HDO®) its unbeatable performance.
