The idea of this pair of sunglasses was to create a clean, authentic style for those who dont just walk the path of life they stomp it and leave footprints. Thats what led to Oakley's Fuel Cell. The idea here is unflinching originality and a smooth look. Its proof that when authenticity speaks for itself, it speaks with volume. The two lenses are actually cut from a single shield of optically pure Plutonite then placed in the frame to maintain the original, continuous contour. An innovation of High Definition Optics, Polaric Ellipsoid lens geometry extends clarity all the way to your peripheral view, exceeding ANSI Z87.1 optical standards. Impact protection meets all ANSI Z87.1 basic standards while UV filtering is an unbeatable 100% for every single ray of UVA, UVB and UVC. The lens curvature and frame architecture improve side protection, and durable yet lightweight O-Matter frame material maximizes comfort with a perfect Three-Point Fit.
