SUSTAINABLE QUALITY WITH
The lasting quality of a lens is guaranteed by good coatings. The basic factors are resistance, durability and easy cleaning. These characteristics provide those who wear glasses with safety and optimal vision, meaning that they will be happy with their glasses. There are now a range of options for refining lenses with certain coatings and making them more comfortable and resistant. As a matter of principle, Wetzlich supplies all the items it produces with indices of 1.60, 1.67 and 1.74 with an additional super-hydrophobic (water and dust repellent) layer.

Spectacle lenses that do not have a finishing coating are highly reflective. As a result, the lenses don’t look good and your eyes are difficult to see for the person you are talking to. Furthermore, light is reflected from the back surface of the lens directly into the eyes of the wearer. The anti-reflection coating ensures a significant reduction in reflection both in the direction of the wearer and of the observer. This provides comfortable and fatigue-free vision. Furthermore, you benefit from less glare reflex, especially at night.

The eyes tend to adjust to any scratch on the lens surface. This strains the eyes unnecessarily and causes headaches and reduced concentration. The plastic lenses are therefore coated with a hard layer to protect them from scratches. In spite of this hard layer, you should make sure that you never put your glasses down with the lenses facing down to protect them.

The super-hydrophobic coating ensures that water and dirt are repelled from the lens surface. Irritating drops of water roll off without leaving streaks on the glass. The coating also makes it easier to clean the lenses.
Blue light filter

As a result of the many hours we spend on laptops, smartphones & tablets, we increasingly experience eye fatigue and even frequent headaches. This is due to the blue-violet light that is emitted by most digital devices. When visible light hits the eye, the blue light waves are more strongly refracted and focused in front of the retina. The resulting diffused light can lead to greater glare at night and to fatigue or burning eyes, e.g. when working on a PC. A blue light filter coating filters out a large part of this light. Important: Not to be confused with the Protect and Protect Eagle Eyes lens materials, where blue light protection is already included in the material.

Even a clear lens can provide 100% UV protection. Applied to the front and back of the glass, the UV blocker layer absorbs all UVA and UVB rays and thus also prevents dangerous radiation from being reflected by the back surface of the lens. Ultraviolet light is not prevented by the normal coating package and can penetrate the eye unhindered, unless the material already has the required properties.
ANTI-REFLECTION COATING WITHOUT RESIDUAL REFLEX

The slightly bluish residual reflex is only 0.2%, which is 80% less than a conventional anti-reflection coating.
