The demands of athletes drove us to create one of the most technically advanced performance sunglasses in the history of sports. Now it comes with a whole new point of view, a lens that combines photochromic technology with a breakthrough in light filtering that has to be experienced to be believed. From ultramarathon runner Dean Karnazes to Mountain Bike World Champion Thomas Frischknecht, the pros tell us it’s the most comfortable lens they’ve ever worn. To reduce eye fatigue and improve performance and safety, photochromic technology automatically darkens and lightens the lens in response to the environment. That’s a huge benefit but it’s not enough. Athletes still need visual contrast when the lens lightens, so we created a lens color called VR50™. It optimizes visual acuity and depth perception with precise filtering along the light spectrum, maximizing performance in sports where split-second decisions demand the best vision possible. Trading distraction for comfort, the lens also eliminates the harsh blue wavelengths that stress your eyes. RADAR has an interchangeable lens design for adapting to any sport environment. HIGH DEFINITION OPTICS® (HDO®) offers unbeatable clarity, and our permanent HYDROPHOBIC™ lens coating repels water sheens, skin oils and dust. The comfortably lightweight O MATTER® frame is sculptured with surge ports to channel a cooling flow of air. Interchangeable nosepiece sizes help you achieve a custom fit, and UNOBTAINIUM® components increase grip with sweat. Impact resistance and clarity meet all ANSI Z87.1 standards, and UV filtering is 100%.
