Grey lenses

Grey lenses are great for sunny days because they reduce brightness without distorting colors, which many other lenses do. They also reduce eye strain. If you fish in rivers with a grey bottom, you should choose grey glasses.

Polarizing polyamide lenses

PA lenses are manufactured by a precision printing machine, giving them superior optical properties and unmatched clarity compared to PC and other plastic lenses. PA lenses also have great resistance to scratches. PA lenses are super light, free of Biosphenol A and the efficiency of polarization is 99%.

Mirror coating

This feature is purely cosmetic and does not affect vision. The only way to tell what color the lens is is to look at it from the outside. A highly reflective mirror coating that makes the wearer's eyes invisible.

Scratch-resistant coating

Despite all the progress made in the development of lens coatings, none are yet completely scratch-resistant – not even glass lenses. Leech spectacle lenses, however, are treated on both sides with a clear, hard coating that makes them highly scratch-resistant.

Anti-reflective coating

Anti-reflective coatings, also called AR or anti-glare coatings, improve both the visibility through the lenses and the appearance of the glasses.
In terms of visibility, the advantage of anti-reflective coatings is that they provide a sharper image.
AR prevents sunlight from reflecting into your eyes from the back of the lenses when the sun is behind you.

Ultraviolet treatment, UV400

This coating protects the eyes from the sun's UV radiation. 100% UVA, UVB and UVC protection.
