The Swash is an easy-wearing oversized frame designed to provide excellent coverage and increased field of vision. Despite its size, it wears lightly thanks to our proprietary bio-based nylon, which is both lighter and stronger than oil-based polycarbonate plastics. Soft, grippy contact points on the nose and temples keep the featherweight frames from floating away, while Fresh Eyes™polarized lens technology blocks blue light to keep eyes free from strain and fatigue to make long days on the water even more enjoyable. This set comes with Green glass lenses.
