Dialed with timeless style and 100% UV protection, the Costa Del Mar Playa Polarized 580 Poly Lens Sunglasses are sure to elevate your daily adventures. These casual shades feature a polarized 580 polycarbonate lens that cuts glare bouncing off glistening bays and shiny road surfaces. Using Costa's 580 technology, these polycarbonate lenses also block visible blue and yellow light to reduce blur on super-bright days. Plus, you'll find the C-Wall lens coating resists water, dirt, oil, and scratches for amazing optical clarity, and the tough nylon frame withstands active wear without premature damage or breakage.
