OPTICIAN SANS

Optician Sans is a free typeface based on the historical eye charts and optotypes used by opticians world wide. Optician Sans is based on the same visual principles as the LogMAR chart, adjusted to be used as a fully functional display typeface. In addition to the basic latin characters we created a set of alternatives glyphs for a more wholesome look. How true you want to stay to the original characters is up to you. You’ll find all characters in the Glyph panel in your preferred layout or type application.

Optician Sans is created by ANTI Hamar and typographer Fábio Duarte Martins. https://optician-sans.com/

George Mayerle’s Eye Test Chart, c. 1907

Lithograph (Schmidt Litho Co., c1907)

from Public Domain Review:

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, and other European readers) and also in Japanese, Chinese, Russian, and Hebrew. A panel in the center replaces the alphabetic characters with symbols for children and 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 (according to one advertisement) for those working on railroads and steamboats.
