The Ishihara test is a color perception test for red-green color deficiencies, the first in a class of successful color vision tests called pseudo-isochromatic plates ("PIP"). It was named after its designer, Dr. Shinobu Ishihara, a professor at the University of Tokyo, who first published his tests in 1917.

The test consists of a number of colored plates, called Ishihara plates, each of which contains a circle of dots appearing randomized in color and size Within the pattern are dots which form a number or shape clearly visible to those with normal color vision, and invisible, or difficult to see, to those with a red-green color vision defect. Other plates are intentionally designed to reveal numbers only to those with a red/green color vision deficiency, and be invisible to those with normal red/green color vision. The full test consists of 38 plates, but the existence of a severe deficiency is usually apparent after only a few plates. There is also an Ishihara test consisting 10, 14 or 24 test plates.

About the Authors

Shinobu Ishihara (石原 忍 Ishihara Shinobu?, September 25, 1879 – January 3, 1963) was a Japanese ophthalmologist who created the Ishihara color test to detect colour blindness. He was an army surgeon.
Ishihara graduated from medicine in 1905 on a military scholarship and immediately joined the Imperial Japanese Army as a doctor, serving mainly as a surgeon. He later changed specialties to ophthalmology. In 1908 he returned to the University of Tokyo where he dedicated himself to ophthalmic research. In 1910 he became an instructor at the Army Medical College. There, in addition to seeing patients, he conducted research on "battlefield ophthalmology" and how to select superior soldiers. While working at the Military Medical School he was asked to devise a test to screen military recruits for abnormalities of color vision. His assistant was a color blind physician who helped him test the plates. The first charts were hand painted by Ishihara in water colors using hiragana symbols.
The name Ishihara is known worldwide because of the Ishihara Color Vision charts which he established in 1918. Even today, his test remains the one of choice throughout the world. Ishihara developed a Japanese visual acuity chart and an apparatus for determining the near point, both currently in wide use in Japan. He also made significant contributions to the study of trachoma and myopia.

In 1908, Ishihara entered the postgraduate course in ophthalmology at the Imperial University of Tokyo, studying under Prof. Jujiro Komoto. Subsequently, he studied in Germany under Professors Wolfgang Stock, Theodor Axenfeld and Carl von Hess. Ishihara was appointed the professor and chairman, to succeed Prof. Komoto, at the Ophthalmology Department of the Imperial University of Tokyo in 1922 and served until March 1940.
