Red Green Color Blindness Tests

The Ishihara Color Vision Test is a test for red-green color deficiencies. 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 contain a circle of dots appearing randomized in color and size.

Neitz Color Vision Test requires no training--It can be administered and scored by virtually anyone, including human resource professionals, teachers, and safety supervisors. The Ishihara, on the other hand, must be administered and interpreted by a trained professional. The Neitz detects both red-green and blue-yellow color vision deficits, whereas the Ishihara identifies only red-green.
