With coatings, you upgrade a lens and adapt it to your individual requirements.


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.

New and Almost Invisible:
Saphir® X Nuance with "Make-up" Effect

“Make-up” Effect for Glasses

Due to the delicate beige-rosé-colored residual reflection of the Saphir® X Nuance, the lens finish adapts to the wearer.

Low Residual Reflex for the Highest Aesthetic Demands

The residual reflection of the Saphir® X Nuance is again significantly reduced compared to traditional anti-reflective coatings with a green residual reflection.

Highest Quality and Durability

The constant further development of our finishing processes ensures a particularly resistant hard layer and an optimized super anti-reflective coating with up to 80% fewer residual reflections. A newly developed top clean and antistatic layer complete the finishing package of the Saphir® X Nuance.

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.

Hard Coating

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.

Super-Hydrophobic Coating

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.
