the first prescription glasses with augmentation for all-day use

With ESSNZ Berlin, tooz launches its first pair of glasses with augmentation for all-day use. The eye wearable will first be shown to the public at AWE USA 2022 starting June 1 in Santa Clara, USA.

tooz technologies, a joint venture of Zeiss and Deutsche Telekom, focuses on the development of optics for individual prescription smart glasses. By launching its first pair of smart glasses for developers in 2020, tooz has already proven that the start-up is capable of designing and producing optical platforms that enable cost-effective and fully functional turnkey smart glasses solutions. After another 1.5 years in development, the team is now unveiling the next generation: a pair of augmented prescription glasses dedicated to the end-consumer market.

The so-called ESSNZ Berlin displays information in the wearer’s field of vision while retaining the original function – individual vision correction – of everyday eyewear. With a slim and sleek form factor, the ophthalmic device is nearly indistinguishable from everyday glasses.

Unique tooz optics for smart ophthalmic glasses

The curved waveguide lens is the centerpiece of tooz’s smart glass solutions. With multiple high-precision free-form surfaces and an invisible combiner, the lens guides light from the monochromatic microLED display in the right temple to the wearer’s eye. This allows the user to see a virtual image in their field of view which provides valuable information. The curved waveguide allows seamless integration of vision correction and thus ophthalmic smart glasses. With the standard back-surfacing process, the individual end-consumer prescription can be easily integrated into every Rx lab around the world.

State-of-the-art technology for everyday use

Through unique technological advancements, tooz is shaping the look and function of smart glasses for end consumers: TOoz SWAP technology is a world first that enables independent lens changing to accommodate a change in diopter or preferences individual lens styles. In addition, the ESSNZ Berlin is thinner, lighter and offers higher energy efficiency compared to previous generations and thus meets all end consumer requirements for daily use.

The information displayed in the wearer’s field of vision is provided via a Bluetooth connection between the phone and the glasses. Once logged in, a wide variety of notifications can be displayed here as standard, along with features such as weather, navigation, calls, messaging, voice assistant and more.

A milestone for the industry

By executing an optics-focused technology roadmap, tooz is leading the evolution from prescription eyewear to ophthalmic wearables. The launch of the first smart glasses with vision correction highlights the will, the knowledge and the expertise in providing turnkey solutions for the end consumer market. With existing and validated reference designs like the ESSNZ Berlin eyewear, tooz enables companies to enter the high-end wearable market in no time and under their own strong brand.

First presentation at AWE USA 2022

Fully functional ESSNZ Berlin smart glasses will be showcased for the first time in booth #743 at AWE USA 2022 starting June 1 in Santa Clara, USA. On Friday, June 3, tooz CEO and Managing Director, Dr. Kai Stroeder, will be on stage to provide exclusive insight into the next generation and optics-focused technology roadmap.
