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.

Physically, Costa's 580G Lightwave glass lenses are:

• 20% thinner and 22% lighter than typical polarized glass
• Encapsulated mirrors (protected by layers of glass) are scratch-proof
• Glass offers the clearest and purest transmission of light

The multipatented technologies embedded in Costa 580G lenses manage light and improve your vision 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

Filtering Out Harsh Yellow

• For enhanced color, sharper contrast and higher definition
