The Oakley Radarlock Pitch Sunglasses are the penultimate mixture of form and function. The Radarlock lets you take advantage of Oakley’s wide array of performance lenses thanks to their ingenious Switchlock™ design that makes changing out lenses fast and hassle free. All the lenses are optimized with the unrivaled clarity and impact resistance of High Definition Optics® (HDO®). HDO® sets the standard for optical clarity and impact resistance, and RadarLock is packed with all those benefits including Polaric Ellipsoid™ geometry to extend clarity across the entire lens. The sweeping contour gives you a wide-open view with maximized peripheral vision and enhanced side protection against sun, wind and impact. You’ll have optical performance rated at ANSI Z87.1, and that same uncompromising level of standards applies to protection against high velocity and high mass impact. For even more protection, our Plutonite® lens material filters out every eye-searing ray of UV. It also comes in an Oakley Soft Vault case that lets you store an extra lens, and each frame comes with two lenses: one for bright days and one for low-light conditions.
