An anti-UV material, but what is it for? To protect your eyes from an invisible danger... UV rays. UV radiation is always present, in winter or summer, in sunny or even cloudy weather, and it can be harmful to your eyes and their contours. To preserve your vision, the lenses of our sunglasses are made of polycarbonate mixed with an \"anti UV\" material which protects you from the harmful rays of the sun (UVA and UVB).

Our lenses are made of polycarbonate, a material that is highly resistant to impacts but whose major weakness is that they are vulnerable to scratching. Bear in mind that even if your lenses are scratched, the UV protection does not decrease; the mirror effect is purely for aesthetic purposes. The same goes for the colour of our tinted lenses. Whether they are grey, brown or coloured… you can choose your glasses according to your taste and you will still be protected, whatever the colour.
