The TAC-3 Sports Sunglasses are a multi-function eye wear system. Designed on the concept of a conventional pair of sunglasses, the TAC-3 Sports Sunglasses have a removable gasket which when fitted creates a seal around your eye orbits. The separate moisture chambers are perfect for sufferers of dry eye syndrome, keeping out heat, cold and wind allowing you to resume every day tasks. There are also a whole host of sports that can also benefit from eyewear that keeps out the wind, dust and debris. If your sports require your eye wear to stay firmly in place, you can change from conventional rigid arms to an adjustable head band, making them a low profile pair of goggles.
