Costa 580 Technology
Yellow light is the enemy. The patented Costa 580 lenses incorporate an advanced filtering compound into the lens material that reduces yellow light. This delivers enhanced colors and better visual acuity in all conditions. It's embedded in the lens, which means it's warrantied for the life of the glasses. All 580 lenses are Costa's LightWAVE glass.
