This lorgnette not only is a well made copy of an original, you can also make use of it. I am near-sighted, and through these glasses my vision is better than with one of the conventional lorgnettes.

The magnification equates that of usual glasses (about threefold).

The size when folded: 11 cm x 6 cm x 3 cm (4.3 x 2.3 x 1.2"), small enough for even a trouser pocket. A leather case is included.

Diameter of the object lens is 30 cm / 11.8".
The small lever has to be reversed to open it. The fine adjustment is done with the ocular.
