Ishihara color test: One of the most common color blindness tests available, the Ishihara color test, is designed to check for red-green color blindness. It consists of a series of large circles made up of a collection of different sized and colored dots. These dots form shapes that are difficult or impossible to see if you are color blind.
While the Ishihara color test is the one most frequently used, many others exist. Some of the more popular tests include the Farnsworth-Munsell 100 hue test, which asks participants to arrange blocks of color according to hue, and the Farnsworth Lantern (FALANT) test, which evaluates the severity of a person’s color blindness.
While many of these tests are available online, patients who suspect they are color blind should visit their doctor for an official diagnosis.
