We\'ve improved this product by adopting design for the lenses, notably through the use of \"shaped lens\" which significantly reduce waste and therefore the product\'s overall impact.

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).
