Need a change of scenery? See things in a whole new light when you put on the Oakley Gascan Prizm Sunglasses. Featuring Prizm polarized lenses, these shades enhance contrast and make colors more vivid, resulting in a bolder and brighter view of the world. They also have a unique style, thanks to Gascan lenses that are cut from the curve of a single lens shield, then mounted in the frame to maintain the original, continuous contour. The Prizm lenses are fined-tuned to specific sports and environments. So for example, the Deep Water Polarized lenses filter out shades of blue that overwhelm your vision when you're far out at sea, and instead highlight greens and reds so you can get a better idea of what's going on below the surface.
