Half Moon style polarized sunglasses by Costa will make you look and feel like a lifelong veteran of the ocean. Sporty, large-fit sunglasses with polarized lenses not only block harmful UV light from damaging your eyes, they help you see through the glare of the tropical sun on the water, to what lies beneath. How many pairs of sunglasses have you lost over the side of the deck or the boardwalk? These Costa half moons include integrated spring hinges, far more durable than the traditional glasses hinge that warps easily, leaving your lenses prone to sliding off your nose. Hydrolite® pads on nose and temples weld your sunglasses in place no matter how much you sweat. These may be the last shades you ever need.
