Swimming is usually tough enough in itself that eye fatigue is one of the last things we notice if we notice it at all. But after a while, squinting through sunlight to sight our way through an open water swim becomes exhausting. TYR tries to cut down on this with its Special Ops 2. 0 Polarized Swim Goggles. Made with polarized, polycarbonate lenses, these goggles are designed to block out the type of glinting sunlight that exhausts your eyes during an open water swim while protecting them from UVAUVB rays and providing a wide field of vision for sighting. Whether you use them in the pool or outside, the goggles are constructed with DURAFIT silicone gaskets to seal out stinging water, and foggy patches won't be a concern with the goggles' anti fog coating.
