We put the wearer in focus and ensure that the tooz optics platform and designs are not only feasible to create but also desirable for daily use
Our mission
Upgrade normal prescription glasses with digital screens through tooz optical engines which enable cost-effective, unobtrusive and turnkey smart glasses solutions.

Our story is unique
tooz technologies GmbH was founded in 2018 as a spin-off of ZEISS and is now a joint venture of Carl Zeiss AG and Deutsche Telekom. We push the envelope of wearable technology today by bringing together competencies in optics, opto-electronics and connectability.
With scalable and cost-effective manufacturing processes, tooz offers a full range of services covering optics, frame design and electronics for both B2B and B2C applications. As well as selling complete solutions like the tooz DevKit, tooz is also able to support third parties in developing their own smart glasses solution.
We are continuously innovating our optical engineering and smart glasses technology at our headquarters and pilot lab in Aalen, Germany.
