We've 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 CellTM. 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 PlutoniteAR then placed in the frame to maintain the original, continuous contour. An innovation of Oakley's patented technologies surpass ANSI Z87.1 standards for clarity, refraction, and prism. High Definition OpticsAR HDOAR, Polaric EllipsoidTM 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 MatterAR frame material maximizes comfort with a perfect Three Point Fit. Think of our 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. If you weren't born with perfect eyes, no sweat Fuel Cell is available with Oakley Authentic True DigitalTM prescription lenses and equipped with Oakley Dual Peripheral TechnologyTM. You'll also see IridiumAR in the list of optional lenses. It's a permanent coating that tunes and balances light while reducing glare.
