Neitz Color Vision Test
by Jay Neitz, Ph.D., Phyllis Summerfelt, and Maureen Neitz, Ph.D.
Offers an alternative to traditional color vision testing, making routine screening possible and practical. The Neitz detects both red-green and blue-yellow color vision deficits, whereas the Ishihara identifies only red-green. Children diagnosed as color-blind using the Neitz also failed the Ishihara and other conventional color vision tests.
