The Ishihara test is a color vision test for detection of red–green color deficiencies. It was named after its designer, Shinobu Ishihara, a professor at the University of Tokyo, who first published his tests in 1917. [2] The test consists of a number of Ishihara plates, which are a type of pseudoisochromatic plate.
By design, the FALANT allows mild color-blindness conditions to pass the test, while still excluding most of the moderate or severe cases of color-deficiency. The test is intended to mimic the types of situations requiring color vision that a sailor would find while serving aboard a ship. A passing test is no mistakes in the first nine pairs ...
An Ishihara test image as seen by subjects with normal color vision and by those with a variety of color deficiencies.

Holmgren's wool test also known as Holmgren's colored wool test is a color vision test used to detect color vision deficiency. Swedish physiologist Frithiof Holmgren introduced the test in 1874. It was the first successful attempt to standardize the detection of color blindness.
The Farnsworth–Munsell 100 Hue Color Vision test is a color vision test often used to test for color blindness.The system was developed by Dean Farnsworth in the 1940s and it tests the ability to isolate and arrange minute differences in various color targets with constant value and chroma that cover all the visual hues described by the Munsell color system.

The commonly used Ishihara test is used to detect mainly congenital red-green color blindness, but its usefulness is limited in detecting acquired color vision deficiencies. [3] But City University test contains test plates that can be used to detect all types of color vision deficiencies. [4]
Color blindness can also result from physical or chemical damage to the eye, the optic nerve, parts of the brain, or from medication toxicity. [2] Color vision also naturally degrades in old age. [2] Diagnosis of color blindness is usually done with a color vision test, such as the Ishihara test.
