Oakley has been experimenting for a long time with the combination of art and technology. The idea is to develop a straightforward and authentic style for those who do not simply celebrate their journey but want to tread on it while leaving deep footprints. That's how the Oakley Fuel Cell ? came into being. The embodiment of irrepressible originality and elegant looks. It not only proves that authenticity speaks for itself, but that it is unmistakable. Inspired by the Declaration of Independence and the "Sons of Liberty". The "Sons of Liberty" created the model for their descendants: Freedom as a top priority, constant vigilance against tyranny and the love of their own country.On this legacy Oakley's American self-image is grounded and the further way carved from this cornerstone. High Definition Optics® (HDO®) The patented and innovative process achieves unique optical accuracy and quality. A wide selection of optional lens colors allows for a reduction in glare, better color perception, greater contrast, and optimized depth perception. The optionally available Oakley polarization lenses block disturbing glare - without the annoying side effects of ordinary polarized lenses such as opacity and distortion. Hydrophobic lens coating Oakley Hydrophobic ? Glass Coating also contributes to high levels of comfort and visual accuracy. It repels dust and provides a barrier against contamination from the skin's natural greasy film, fingerprints, lotions and sunscreen. Even water bubbles off, so it does not come to unwanted streaks and highlights. Shock resistance to both high velocity and high mass shocks meets all requirements of ANSI Z87.1 standard. Plutonite® The spectacle lens material Plutonite® filters out 100% of the UVA, UVB and UVC radiation, as well as harmful blue light components in the range up to 400 nm. Unobtainium® The temple tips and the nose pad are coated with a material that has a reinforced grip of the glasses in case of increased transpiration. Thus, the glasses are safe and secure at all times. Glass color Prizm Ruby Polarized A neutral, red base lens with a mirrored surface, which is ideal for medium to bright light. Ruby Iridium filters out 83% of ambient light and blocks 100% of UVA, UVB and UVC light. Oakley's HD polarized lenses eliminate annoying glare without compromising clarity.
