Innovation concept – ESSNZ SLIM


ESSNZ SLIM revolutionizes the way smart prescription eyewear
will look and feel

The innovative reference design “ESSNZ SLIM” represents a significant evolution from previous smart glasses. Building upon the success of the ESSNZ Berlin design, we have meticulously refined and enhanced the functionality to create a uniquely light and slim solution. This design is perfectly tailored to meet the needs of end consumers for all-day use glasses.

“ESSNZ SLIM” provides the proof that consumer style expectations, medical-grade correction optics and visual augmentation can be realized in a valid product offering.


Designed with user comfort and style in mind, the “ESSNZ SLIM” smart glasses offer an unparalleled AR experience. A weight of less than 40 grams and an ergonomic design allows users to wear these glasses all-day long.


Achieving the target of a sleek and minimalist form factor, tooz did not compromise to deliver one core differentiator: individual vision correction.

tooz has again leveraged its state-of-the-art optical system, a curved waveguide with free-form surfaces and prescription integration, to guarantee natural AR experiences in future prescription glasses.
