The monoculars in the DesignSelection line are so compact that they can be carried around as easily as a pocketknife. the models with 3x to 6x magnification are also telescopes and magnifiers in one. This magnifying ability makes them particularly valuable for people with extremely poor vision. By simply turning the momocular over and looking through the objective lens, a menu in a restaurant or small print on a program page become visible.

Zeiss monoculars are also appreciated by enthusiastic naturalists as a valuable addition to their binoculars. Due to the low weight and compactness of the monocular, it can be carried at all times - either in a jacket pocket or purse. Thus, it can be readily available for close-up viewing.
