UV rays.UV radiation is always present, in winter or in summer, in sunny weather or even overcast and it can be harmful to your eyes and their contour.To help preserve your vision, our sunglasses lenses are made from polycarbonate blended with “anti-UV” material which protects you from harmful sun rays (UVA and UVB). #### GLARE Categorisation of tinted lenses according to the ISO 12312-1 standard:- Category 1: slightly tinted lens for reduced solar luminosity.- Category 2: medium tinted lens for medium solar luminosity.- Category 3: dark lens for heavy solar luminosity (sea and mountains).
