Visual Aids For Eye Testing (USA)
This is a Visual aids for eye testing.
This object is not part of the Cooper Hewitt's permanent collection. It was able to spend time at the museum on loan from National Museum of American History as part of Tools: Extending Our Reach.
This booklet of simple eye tests from the 1930s captures a host of assumptions about people and their cultural competencies, from card playing and singing to understanding train schedules and shorthand. The first standardized eye chart is believed to have been developed by Dutch ophthalmologist Herman Snellen in 1862. Snellen’s test of visual acuity set a standardized distance from patient to chart of 20 feet in the United States and 6 meters in Europe. This inexpensive and portable chart has eleven lines of symbols, called optotypes, from a single large letter at the top to the smallest letters at the bottom. The letters are carefully shaped so as to balance the amount of white to black space. Similar charts followed, such as the Lea chart designed in Finland in 1976 that uses objects, like a house or a ring, to cater to children and others who are preliterate.
