Sunglasses with polarized mirrored Zeiss lenses. Resulting from cutting-edge technological research, these sunglasses ensure the very best performance for people who practice extreme sports. Designed especially for use on sailboats, they have a floating frame that reduces the risk of losing them in the water. The water repellent treatment helps these glasses resist water, salt, and sand. The polarized nylon Zeiss lenses are antiglare and scratch-resistant, offering complete protection from UV rays: They are designed to reduce blue light that assails the eye in order to make it easier to distinguish subtleties by providing high-contrast vision. The arms on these glasses are made with dual injection rubber for greater shock resistance and feature a neoprene keeper to hold the glasses on your head and help prevent them getting lost.
