How to choose lens material
From day one, our lenses have set us apart.
All Costa lenses have 100% UV blockage for
maximum protection and 100% polarisation to kill reflected glare.
Our 580 technology goes beyond polarisation to produce the best lenses on the planet. It
selectively filters out the harsh yellow and harmful high-energy ultraviolet blue light,
making colours 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.
