Quechua Adult Polarised Category 4 Hiking Sunglasses

Our optical engineers developed these sunglasses for hiking. Ideal for use in the mountains thanks to their light weight, as well as their hold.Anti-UV lenses block out 100% of the sun’s harmful rays and category 4 protects you from glare. The technology of polarised lenses lets you make out hilly areas and contrasts better.

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 absorbed

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.

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.
