Eye-Glasses Double for Microscope, Modern Mechanix, Jul, 1936.

EYE-GLASSES which can be used instead of a microscope have been invented by C. Dreisseg of Hamburg, Germany. The glasses obtain their microscopic power from specially treated dark paper.

This paper changed the focus of the eye so as to magnify the size of a fixed object. Even minute particles can be distinguished. The dark paper is encased in a leather band which fits snugly around the eyes to exclude all possible light rays. The novel glasses are ideal for student use.
