Costa blackfin sunglasses are the epitome of Costa innovation, technology, and design. Costa sunglasses are made with an emphasis on being water resistant, durable, and comfortable. Costa blackfin sunglasses are made with cold-injected nylon and hydrolite frames, which grip more when exposed to sweat and water. Costa Del Mar blackfin frames are hand-assembled. Integral stainless steel hinges provide durability and stability. TR-90 nylon frame is scratch, sweat, and shatter resistant. Polarized lenses provide relief from glare that comes from water and intense sunlight. Comfortable, large fit is good for larger heads. Costa blackfin sunglasses are available in alternate fit which flatters those with higher cheek bones. . Mirror coatings are suitable for protection from intense light. A mirror coating reflects back light and reduces the amount of light passing through the lens. This makes it more comfortable for eyes in very sunny conditions.
