Pseudoisochromatic plates frequently are used by eye specialists to get an idea of one’s color efficiency or deficiency. The Ishihara color test, used to detect protanopia and deuteranopia color deficiencies, was designed by Dr. Shinobu Ishihara (1879–1963), a professor at the University of Tokyo.
The test includes several pseudoisochromatic plates, each composed of a pattern of differently shaded dots. Within each pattern, a number is present.
To a color-deficient person, all the dots in one or more of the plates will appear similar or the same—“isochromatic.” To a person without a color deficiency, some of the dots will appear dissimilar enough from the other dots to form a distinct figure (number) on each of the plates—“pseudoisochromatic.”
This application is designed to use the same phenomenon to test you color vision.
