Reference: 8650014 LENS TINT : Lens tint: grey. The grey tint is excellent at rendering natural colours and reduces light intensity. It is the tint most suited to watersports. Mirror effect: purely aesthetic. Be careful to protect your lenses from scratches, which will be more visible on these types of lenses. POLARISED TECHNOLOGY : Ideal in case of strong glare! The lenses block indirect rays coming from below (from the snow, sea or sand). >Enhances contrast and allows the wearer to see the terrain even in strong glare Stray reflections are reduced to prevent the wearer from being dazzled. Warning: with polarised lenses, it can be difficult to read screens such as phone screens. A rainbow effect appears on the screen. ANTI-UV LENS : What does anti-UV material do? To protect your eyes from an invisible danger... UV rays. UV rays are always there, in winter and summer, in sunny or even overcast weather and they can be harmful to your eyes and what surrounds them. To maintain your eyesight, the lenses of our sunglasses are made from anti-UV polycarbonate which protects you from harmful sun rays (UVA and UVB). GLARE : Classification of tinted lenses according to the ISO 12312-1 standard: - Category 1: lightly tinted lens for low brightness. - Category 2: moderately tinted lens for medium brightness. - Category 3: dark lens for strong sunlight (sea and mountains). Between 82% and 92% of visible light absorbed - Category 4: very dark lens, for extremely bright sunlight (high mountains). Between 92% and 97% of visible light absorbed LENS MATERIAL : Our lenses are 1.5 mm polycarbonate, a highly resistant material but the major drawback is that it is susceptible to scratches. Be aware that even if your lenses are scratched, the UV protection is not reduced, the mirror effect is purely aesthetic. The same goes for the colour of the sun lenses. Whether they be grey, brown or coloured... you can choose your glasses according to your preferences, you will be protected regardless of the colour. FRAME : Frame material: polyamide Arm material: polyamide Size: suitable for medium to large faces ECO DESIGN : Our product is ecologically designed thanks to the work led to limit the thickness of the lens without affecting the solidity or quality of vision. By using a 1.5 mm lens instead of 2 mm (thickness normally used for sunglasses), we have reduced the CO2 impact of this model by 10%. We continue to work so that our CO2 impact continues to go down in order to limit their environmental impact as much as possible.
