TECHNICAL INFORMATIONS
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.
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).
Lens category
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 absorbed
PHOTOCHROMIC TECHNOLOGY
The colour of the so-called "photochromic" lenses varies according to the amount of UV rays.
The activation time to change from the light tint to the dark tint (categories 2 to 4) is about 1 minute. The deactivation time to change from the dark tint to the light tint is about 3 minutes at room temperature (23°C).
The lenses adapt directly to the amount of UV light emitted outdoors to provide better protection for the wearer according to the weather conditions.
