Description
Title: Eye test chart. Positive image. Published: 1907. George Mayerle's eye test chart, combining four subjective tests done during an eye examination. Running through the middle of the chart, the seven vertical panels test for acuity of vision with characters in the Roman alphabet (for English, German, & other European readers) & also in Japanese, Chinese, Russian, & Hebrew. A panel in the center replaces the alphabetic characters with symbols for children & adults who were illiterate or who could not read any of the other writing systems offered. Directly above the center panel is a version of the radiant dial that tests for astigmatism. On either side of that are lines that test the muscular strength of the eyes. Finally, across the bottom, boxes test for color vision, a feature intended especially for those working on railroads & steamboats. Printed in/Ships from USA. Unframed: print only.
