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.
