In order to maintain the original, continuous contour of the Oakley Gas Can Sunglasses, Oakley cut two lenses from the curve of a single lens shield then mounted them in the frame. The look of the Gas Can Sunglasses is so unique, that Oakley customized their corporate logo just for these sunglasses. The Oakley Gas Can's also feature a lightweight O Matter Frame offering premium comfort, peripheral vision that is maximized by XYZ Optics, impact protection that meets ANSI Z87.1 standards and the Three-Point Fit that retains the lenses in precise optical alignment. True metal icons sign these Oakley Gas Can Sunglasses original. Lightweight O Matter frame material with Square O metal icon accents. Oakley Twin Toric lens technology with HDO. Iridium and polarized lens options available.
