Oakley's been toying with a mix of art and technology for some time. The idea was to create clean, authentic style for those who don’t just walk the path of life – they stomp it and leave footprints. That’s what led to Oakley FUEL CELL™. The idea here is unflinching originality and a smooth look. It’s 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® (HDO®), POLARIC ELLIPSOID™ lens geometry extends clarity all the way to your peripheral view, exceeding ANSI Z87.1 optical standards. Impact protection meets 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.
