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.
