TECHNICAL INFORMATIONS

ANTI-UV

What use is anti-UV material?
To protect your eyes from an invisible danger... UV rays.
UV radiation is always present, in winter or in summer, in sunny weather or even overcast and it can be harmful to your eyes and their contour.
To help preserve your vision, our sunglasses lenses are made from polycarbonate blended with “anti-UV” material which protects you from harmful sun rays (UVA and UVB).

Polarised

The best for your outdoor activities!
The polarised lenses make colours more vivid and improve contrasts and landscapes.
They give very good protection and are extremely comfortable with light hitting only one axis. They also protect against glare by cutting off rays that reflect on a horizontal surface (water, snow, etc.).
The only downside is that it’s difficult to read screens (phone, etc.) as the polarising treatment reduces screen light.

GLARE

Categorisation of tinted lenses according to the ISO 12312-1 standard:
- Category 1: slightly tinted lens for reduced solar luminosity.
- Category 2: medium tinted lens for medium solar luminosity.
- Category 3: dark lens for heavy solar luminosity (sea and mountains). Between 82% and 92% of visible light absorbed
- Category 4: very dark lens for exceptional solar luminosity (high altitude). Between 92% and 97% of visible light absorbed

Good to know

Our lenses are made from polycarbonate, a shock resistant material however the big disadvantage is that it is prone to scratches.
Even if your lenses are scratched, the UV protection is not reduced as the mirror effect is purely cosmetic.
The same thing for the colour of our solar lenses.
Whether grey, brown or coloured... you can choose the glasses you like, you will be protected whatever the colour.

FRAMES MADE FROM BIOSOURCED POLYMER

We use Rilsan Clear G850 Rnew, a polymer derivative from castor oil, for the frame of these sunglasses.
This biosourced material is a real asset in our developments so we can make a lightweight and flexible frame.

GLASSES FRAMES WITH REDUCED ENVIRONMENTAL IMPACT

To reduce the environmental impact of our glasses, we can take action on material.
We reduce the use of varnish and paint on these sunglasses frames, everything is directly integrated in the product mould.
This is still not enough and that's why we are working to make these sunglasses 100% eco-designed one day.
