All the important information about our carbon glasses made from FLEXARBON®

Personal Service

Handmade in Germany at our own production site

From the carbon fabric to the finished frame, every step is carefully executed in our workshops in Germany. First, the raw carbon is processed into our patented FLEXARBON® material for eyewear. Then it is used to make the frames. Since we manufacture every single component ourselves, we can react quickly and flexibly to special requests and ensure the best customer experience. Fast adjustments, spare parts and warranty are natural for us.

Kerl Eyewear patented carbon material FLEXARBON® for eyewear

Robust and flexible

Specially developed material FLEXARBON® for eyewear

After many years of development, our eyewear material has its own name: FLEXARBON®. Up to eight layers with millions of fibers processed by hand by our highly skilled team. The fiber structure and surface of each individual pair of glasses is unique, as is each frame.

Precise Customization

Modular kits

For the highest level of wearing comfort, we developed a new way of fitting templetips in close cooperation with leading opticians. The high-precision 3D printed elements are ergonomically shaped and can be exchanged as well as thermoformed. The same applies to the nosepad-arm: made of the best beta titanium, they can be adjusted precisely to the customer’s needs. The patented hinge can also be used to ensure the inclination of the temples and thus the perfect alignment of the frame.

Highest level of wearing comfort

The lightest frame glasses worldwide

The right weight distribution makes all the difference here. In total, our frames weigh as little as a sheet of paper. With slightly heavier temple ends and our extremely lightweight front of the glasses, the pressure is taken off the nose and outstanding wearing comfort is ensured.

Tool-less and 100% customizable glasses

German engineering meets
Swiss design

Our patented carbon hinge is screwless and can be mounted without tools. The highlight is the integrated adjustable bracket tilt. A shear stress spring in the material ensures optimum opening behavior – consistent for more than 100,000 movement cycles. The passion in the product design is clearly noticeable. Thus, despite their functionality and lightness, the glasses do not lose expression at the front.
