ANTI-UV

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).

Polarised

The best for your outdoor activities!The polarised lenses intensify the colours and improve contrasts as well as the view of the terrain.They provide good protection and excellent comfort by only transmitting the light in one axis, while also protecting you from glare by blocking the rays which are reflected off horizontal surfaces (water, snow, etc.)The only downside is that it makes it difficult to read screens (phone, etc.) as the polarising treatment lowers the brightness of the screens.

GLARE

Classification of tinted lenses according to the ISO 12312-1 standard- Category 1 lens with a light tint for reduced sunlight.- Category 2 lens with a medium tint for average sunlight.- Category 3 dark lens for strong sunlight (sea and mountains). Between 82% and 92% of visible light absorbed- Category 4 very dark lens, for exceptionally strong sunlight (high mountains). Between 92% and 97% of visible light absorbeds4

Good to know

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.s5

FRAMES CREATED USING A BIO-BASED POLYMER

For the frame of these sunglasses we use Rilsan Clear G850 Rnew, a polymer made from castor oil.This bio-based material is a real asset in our development process and is tailored to making lightweight and flexible frames.s6

MORE ECO-FRIENDLY GLASSES FRAMES

To reduce the environmental impact of our glasses, action can also taken on the material used.On the frames of these sunglasses, we have reduced the amount of varnish and paint, and everything is incorporated directly in the mould of the product.This is not yet enough, which is why we are working to ensure that, one day, these sunglasses will be 100% eco-designed.s7
