Performance Lens Technology
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
Filtering Out Harsh Yellow
- For enhanced color, sharper contrast and higher definition

Choosing a Lens Material
From day one, our lenses have set us apart. All Costa lenses have 100% UV blockage for maximum protection and 100% polarization to kill reflected glare. Our 580 technology goes beyond polarization to produce the best lenses on the planet. It selectively filters out the harsh yellow and harmful high-energy ultraviolet blue light, making colors brighter and objects appear more defined. So no matter what you are doing under the sun, you’ll see it in stunning detail.
Glass lenses are best for situations that require ultimate clarity, and our plastic lenses are more cost effective while being more durable for more demanding applications without sacrificing clarity.
