SI Fuel Cell Thin Red Line Satin Black Frames with Black Iridium Lenses

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.

With HDO, Oakley lenses meet or exceed the testing standards of the American National Standards Institute (the yardstick of performance for the eyewear industry).The Clarity Test measures the sharpness of images viewed through the lens. The Refractive Power Test measures how inferior lenses distort vision by magnifying images, and the Prism Test measures how the lenses bend light and make objects appear shifted from their true position. These tests show how conventional lenses can compromise your vision.
