Enjoy mountain fun with the expanded lens of the Oakley Fall Line Prizm. The Fall Line Prism was designed so you can enjoy a wide-open view with maximized peripheral and downward vision. The razor-sharp optics take advantage of Plutonite lens material that filters out 100% of all UV Light. Combine that with the Dual-Vented lens with F3 Anti-Fog Coating and you'll have an unprecedented view that is free of fog. The Prizm Lens gives you incredible visibility and enhanced details and contours in the snow, especially in difficult light conditions. The Fall Line Prizm is designed for improved compatibility with helmets and most prescription eyewear frames. Just in case you need to wear prescription eyeglasses underneath your goggles the Fall Line has small notches in the frame that allow space for most glasses. The Oakley Fall Line Prizm Goggles boast an oversize field of view without compromising fit so you can see it all and embrace the terrain you are about to rip up below you.
