Designed to provide maximum protection from the elements, Live Xtreme features attributes not found in any other OveRx sunglass collection. The full wrap patented SportsFrame™ comfortably slips over existing prescription frames to completely isolate the eyes from the harmful effects of the sun and damaging UV in addition to sheltering the eyes from wind, rain and other airborne irritants. The polarized polycarbonate sport lenses cut through glare to provide crystal clear optical acuity and feature a hydrophobic armor to eliminate moisture formation on the lens surface. All Xtreme OveRx sunglasses are certified ANSI Z87.1-2003 for high impact resistance. Comfort and performance during extended wear are enhanced by non-slip nose pads and Flex2Fit™ adjustable temples. All Live Xtreme sunglasses are backed by a limited lifetime warranty.
