Explore isolated coves with the Costa Del Mar Corbina Limited Edition Polarized Sunglasses. Their polarized 580 glass lenses eliminate glare, provide superior clarity so you can truly take it all in, and are 20% thinner and 22% lighter than most glass lenses for enhanced comfort. Glass lenses also resist scratching better than polycarbonate. The 580 lens enhances colors by blocking yellow light and eliminates haze and blur by blocking blue light. Hydrolite nose and temple pads cover the heavy duty TR 90 nylon frame so these sleek shades don't fall off your face, and the stainless steel hinges won't rust if you decide to take a dip.
