POLARIZED LENSES

Polarized lenses are a must-have no matter the weather due to their ability to filter out horizontal light waves. Combined with our 100% UVA-UVB protection, this is a two-in-one solution that cuts down on glare, improves contrast, and makes the field of vision more clear so you no longer have to strain to see on the road or in the water.
