PU lenses
Our lenses are made of polycarbonate, a highly shock-resistant material which has the main disadvantage of being scratch-sensitive.But even if your lenses are scratched, the UV protection doesn't decrease – the mirror effect is purely aesthetic.The same is true of the colour of our solar lenses.Whether they are grey, brown, or coloured … you can choose the glasses you like and you'll be protected whatever the colour.
Anti-UV lenses block 100% of harmful rays, and photochromic lenses (NXT) that tint according to UV intensity protect you from glare, from CAT2 to CAT4.
