Polarized lenses

Composed of a polarizing filter, they block annoying reflections and remove glare on sunglasses.

They also allow a better contrast perception and offer optimal comfort and protection.

Mirror lenses

First appreciated for their aesthetic effect, they also strongly block light and reduce glare.

Gradient lenses

These lenses consist of a dark color on the upper part and a lighter shade on the lower part.
The whole lens offers 100% protection from harmful UV and has CE certification in accordance with European directives

The gradient lenses are very useful in conditions of variable luminosity
(better vision of pages for the reading or dashboard during the driving thanks to the clearer bottom)

Generally, if the top is of category 3, the bottom is it, of 2 or 1.

Photochromic lenses

Category 3 lenses

Category 3 lenses are suited to most periods of sunlight, when you are in direct sunlight in a medium-altitude mountain, in town or at the beach.

They provide a perfect sun protection (against UVA / UVB) and considerably reduce glare.

They are highly recommended when you are intensely exposed to strong sunlight (mountain, sea...).

It is the highest category authorized for driving.
