Grey lenses

Grey lenses are great for sunny days because they reduce light intensity 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.

Polarized triacetate cellulose (TAC)

TAC lenses are formed from plastic plates using a multi-layer lens technology. It is the lightest polarized lens available and the efficiency of the polarization is 99%.

Ultraviolet treatment, UV400

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

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.
