Color Deficiency Test
PseudoIsochromatic Plates frequently are used by eye specialists to get an idea of one’s color efficiency or deficiency. To a colordeficient 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."
Try to determine what number is encompassed within each plate. Some of the numbers are difficult to see, even for people with normal color vision.
