Costa 580® Lenses

Beyond Polarized

Costa 580 lenses were designed by in-house light spectrum experts to enhance colors because standard sunglass lenses fell short. The lens’ multipatented technology manages light by:

Absorbing Harmful High-Energy Blue Light (HEV)

Cuts haze and blur for greater clarity
In addition to 100% protection from UV light, 580 technology also absorbs HEV light known to cause macular degeneration, pterygium, cataracts and other eye diseases

Enhancing Reds, Greens, and Blues

Blocking harsh yellow light at 580 nm on the visible light spectrum boosts the amounts of red, greens and blues naturally, enhancing colors and contrast
