Thank you for viewing. Purchased from the Oakley official website and used about 5 times during marathons. These are photochromic, light-adjusting lens specifications. They are in good condition, but are used, so please check the photos. [Overview] Oakley's original Radar eyewear is the culmination of all the research gained over the past decade, with the cooperation of the world's top athletes. The Radar EV, with its vertically extended lens, has set a new milestone in the tradition of performance by expanding the upper peripheral vision area. #Sunglasses #PhotochromicLens #Photochromic #Oakley #Radar #Marathon #RoadBike
