For the most durable and mission critical eyewear around, make sure you're wearing the Oakley SI Cerakote Gascan Sunglasses. The Mil Spec Green colored, lightweight, rugged O Matter frame material maximizes comfort for all-day wear, while being extremely durable and tough enough for anything you take on. Sculpturally integrated hinge mechanisms with dual cam action ensure that these sunglasses stay snugly on your head and also allows for easy on/off access. Featuring dual lens Polaric Ellipsoid geometry, which has two lenses cut from single toric shield, the Black colored Plutonite lenses blocks 100% of all UVA, UVB, UVC and harmful blue light. XYZ Optics maximize clarity at all angles of vision, so you can be ready for anything at all times. In addition, the Iridium coating and lens tint reduces glare and heightens contrast for an even more high-performance field of vision. The Cerakote Gascan frame and lenses exceed ANSI Z87.1 standards for impact and optical requirements, so you don't have to worry about your sunglasses holding up under intense conditions. Metal icon accents add to the already futuristic design for a look that is sure to wrap your eyes in style.
