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.

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%.

Lens Coating

Hydrophobic coating

Imagine how much better you would see in the rain with a pair of hydrophobic lenses.
Such a coating binds the molecules in the lens together so that water cannot penetrate and cause permanent damage. It also means that the lenses do not need to be cleaned as often as other lenses, while they are also easier to clean. Sunglasses with a hydrophobic coating provide clearer vision because water runs off the lenses more easily.

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.

Ultraviolet treatment, UV400

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