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.
Color blindness is typically tested using the Ishihara color test, which consists of a series of plates with colored dots and numbers that are hidden to those with color vision deficiency. Individuals are asked to identify the numbers within the dots to determine if they have a color vision impairment. Another method is the Farnsworth D-15 test, where individuals arrange colored caps in a specific order to identify any color vision deficiencies.
