The Fuel Sunglasses from Oakley are part of the Oakley High Definition Optics (HDO) line. Oakley combines patented optics and Plutonite lens material that provides 100% UV filtering and unsurpassed impact protection.Oakley has 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 frame makes contact only at the nose bridge and temples, thanks to a Three-Point Fit that utilizes Unobtanium components to increase grip with sweat.
