Passion for Precision
Optical lenses – made in Germany

Since 1935, we have been producing precision and innovative lenses that are distributed through optical retailers.

Our dedicated team produces and develops high-quality lenses that provide real added value to the wearer. Since 2022, we have been based in Korschenbroich near Mönchengladbach, where we work every day on products that make people‘s lives easier and richer. Whether it‘s sunglasses with UV and infrared protection, lens materials that make driving at night easier, or materials made from 82% renewable resources:

We know that lenses can do more!

„With one of the most modern machine parks in Europe, we stand for „Made in Germany“, sustainability, innovation, and progress.“

Made in Germany
Optical lenses from Germany

We believe in the added value of „made in Germany“, which surprisingly often has a higher value abroad than in Germany itself. Supply security and stock protection are the counterpoint to the one-sided dependence on Asian suppliers. The optical industry has a long history here.

In addition to the more emotional aspect of a traditional industry, there are also many objective reasons that speak in favor of production in Germany. These include, for example, job security in one‘s own country, creating sustainable production, as well as technological independence and flexibility.

Creating Progress
Innovations & added value

We are one of the last companies in our industry to manufacture in Germany. Despite the industry trend towards international corporations that rely on outsourced mass production, we at Wetzlich are taking new paths. Our goal is to offer lenses with clear added value for the wearer – the purpose should not only be fulfilled, but surpassed.

When developing our lenses, we invest a lot of time to achieve the best possible result for our customers. For this purpose, we also work with external experts who support us in medical expertise and software development.

For our new developments and our commitment to research and development, we made it to the Top 100 of the most innovative medium- sized companies in Germany in 2019/2020. The award honors the innovation management of medium-sized companies in Germany. We are proud to be part of this group of innovative companies.

Sustainability &
resource-saving production

In recent years, our perception of the environment and the use of resources has fundamentally changed, placing immense demands on the industry. In Germany, however, the industry is also faced with completely different requirements.

In the MAFO interview „Fit for the Future – Challenges and Opportunities for Medium-sized lens Manufacturers“, MAFO editor Rebekka Nurkanovic talks to Florian Gisch about ways to prepare the company for the future and which driving factors play a role in this.
