Costa Sunglasses

Costa Del Mar polarized sunglasses built around proprietary 580 lens technology, which filters high-energy blue and yellow wavelengths to sharpen contrast and color definition on the water. Lenses come in 580G (glass, 20% thinner than standard polarized glass) and 580P (polycarbonate, lighter and more impact-resistant), both 100% polarized and UV-blocking. Lens tints include copper and sunrise silver for sight-fishing and low-light, and blue mirror and gray for offshore and bright conditions.
