Featuring innovative PRIZM technology that delivers fine-tuned visual performance, the Oakley SI Radar EV Path PRIZM is built for shooting in a wide range of lighting conditions. These glasses are made with a lightweight, impact and chemical-resistant O Matter frame for non-stop durability and comfort. This frame features a hydrophilic Unobtainium nose pad to hold the glasses in place, even in wet conditions. Plutonite lenses filter out all harmful UV rays, and use Polaric Ellipsoid geometry to maximize your field of view. These durable glasses meet ANSI Z87.1-2003/2010 standards for high-mass and high-velocity impact protection, and provide clarified vision to perform in specific environments and activities.
