The Oakley Fuel Cell Tour De France Black Glasses with Black Iridium Lenses have 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 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. Think of the polarization as a glare kill switch that's always on. Oakley HDPolarized lenses are an option for FUEL CELL, and they block 99% of those irritating rays that interfere with vision. It's a permanent coating that tunes and balances light while reducing glare.
