All Costa Lenses are Polarized

On top of that, all Costa Sunglasses are polarized. Costa has established themselves as a premium polarized company with their 580 lens technology. Each Costa sunglass will have a polarized coating embedded in the lenses. Costa's 580 goes beyond polarization. Costa's lenses will filter out the harsh yellow light and filter out the bad HEV blue light. Essentially if you have authentic Costa sunglasses with the 580 etched in the top right lens, your eyes will always be protected. Also, Costa offers 7 different signature lens tints. Check out the diagram below to see how Costa 580 lenses differentiate themselves from other sunglass brands.
