Versatile. Sleek. Comfortable. Fast. Rxable. True Breakthrough Vision by Rudy Project. The EXCEPTION™ offers a vast array of features all packed into a stylish cutting-edge design. Building on Rudy Project‘s success in techno-ergonomic 8-base sport designs (Ketyum™, Rydon™) and our revolutionary flip up technology, (RB3™, Perception ™, Kabrio ™) the Exception ™ is truly a design masterpiece that has incorporated all of our major technologies in one model -including the option to add RXability using our patented optical inserts (2 configurations available, for low or high/progressive prescriptions). RP Optic polycarbonate lenses can be put directly into the frame or ingeniously added to our flip-up mechanism that attaches to the frame - offering two vastly different functionalities and appearances. The Exception™ incorporates Quick Change™ interchangeable lens technology, adjustable Ergonose™ nose pads (to eliminate fogging) and adjustable Kynetium™ temples equipped with our T-Lock™ system (for a customized, total comfort fit every time and for every sport). Advanced lightweight Grilamid™ TR 90 frame material and geometric wrap technology means you won‘t even know you have them on! Sports enthusiasts and prescription wearers of all types will swear by Exception™ after one wearing. The Exception™ is true breakthrough vision!
