Costa Del Mar Blackfin Polarized Sunglasses - Costa 580 Glass Lens Black/Green Mirror One Size. Throw on the Costa Del Mar Blackfin Polarized Sunglasses and head down to the beach for some much needed R&R. The Costa 580 polarized glass lenses resist scratching when you toss em in the sand for a swim and cut glare off of the water and enhance clarity when you scope the swells. The bold frames and wide temples ride comfortably and block out ambient light as you doze off in the summer sun.
