Protect your eyes from an invisible danger... UVs. The UV radiation is still present, in the winter and summer, in sunny or even cloudy weather and can be harmful to your eyes and their contour. To protect your vision, our sunglasses' lenses are made from polycarbonate mixed with an "anti-UV" material that protects you from the harmful rays of the sun (UVA and UVB). Polarised : Great for your outdoor activities! The polarising lenses intensify colours and improve contrast and relief. They also provide great protection and excellent comfort, the light only arrives on 1 axis, and they protect from glare by cutting the rays that reflect on a horizontal surface (water, snow, etc). The only issue is that it can be difficult to read screens (telephone, etc) as the polarising treatment cuts out the light from screens. GLARE : Classification of tinted glasses according to the standard ISO 12312-1: - Category 1: slightly tinted lens for greatly reduced sunlight. - Category 2: medium tinted lens for average sunlight. - Category 3: dark lens to for strong sunlight (sea and mountains). Between 82% and 92% visible light absorbed - Category 4: very dark lens, for exceptional sunlight (high mountains). Between 92% and 97% visible light absorbed Good to know : Our lenses are made from polycarbonate, a very durable shock-resistant material with one major inconvenience, it is sensitive to scratches. Even if your lenses are scratched, the UV protection does not drop, the mirror effect is purely aesthetic. The same as for the colour of our solar lenses. Whether they are grey, brown or colourful... you can choose the sunglasses you prefer, you will be protected no matter what their colour. GLASSES FRAMES WITH A LOWER ENVIRONMENTAL IMPACT : To limit our sunglasses' environmental impact, we can also change the material. On the frames of these sunglasses, we limit the use of varnish and paint, it is all integrated in the product's mould. It isn't enough, that is why we are working so that these sunglasses are one day 100% eco-designed.
