Adults Category 3 Hiking Sunglasses MH140

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).

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

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.

Our glasses will join you on your mountain walks. Your lenses may scratch over time. To help to repair them, our polarised lenses (reference 8655386) or non-polarised (reference 8655382) are available so you can replace them yourself quickly and easily. Our environmental approach at Quechua also supports making these parts available to you. Don't throw away, repair!

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.

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.
