Most commonly, color blindness is diagnosed through the Ishihara Color Test. This consists of a set of plates, each displaying a circle of dots appearing randomized in color and size. Within each Ishihara plate is a number that should be perceptible to individuals with normal vision.
The US Navy and US Army also allow testing with the Farnsworth Lantern Test, also known as FALANT. This test allows 30% of color deficient individuals, whose deficiency is not too severe, to pass.
