Keystone Model 40 Comfort Eye Stereoscope

United States, 1930s

In the 1930s, Keystone started a stereo-optical department for “the development of skillful and comfortable vision.” They produced a number of stereoscopes to be used with special eye training stereoviews that were available by prescription only. The stereoviews exercise one’s eyes when the user shifts focus between different numbered markers on the cards. Keystone claimed, “The human body is benefitted by proper exercise. The eyes are no exception.”

We also have a Model 40 with an easel and a Model 50 in our collection.

Provenance

This beautiful Keystone Model 40 belonged to Francis (Frank) Garty and was donated to our collection by his grandson. Frank immigrated from England to San Diego in 1906 at the age of 16. He found work as a landscaper, married his wife at 18, and they eventually opened a florist shop on Gerard street in La Jolla, which they ran for 25 years. According to his relatives, he enjoyed this stereoscope immensely.
