Markus Temming has brought something completely new to the optical world. His driving principle is to bring together the minimalist ideal of 'reduction to its essence' with state-of-the-art technology. Roughly translated from German, "This has been achieved when aesthetics, functionality and longevity sit in perfect harmony."

Manufactured in Gutersloh, Germany, all components of Markus T glasses are bound to one another without screws. A square hinge joint ensures long life and durability of the frames; developed in the mid-1990s, this hinge is the trademark of the Markus T collections.

Iris Optical first introduced Markus T frames in June 2007.
