Product Details

Red/green color blindness is an inherited condition in which certain colors of red and green cannot be distinguished. In 1917 Dr. Shinobu Ishihara developed a simple and accurate method to test for red/green color deficiency using a pattern of dots within a circle. Still regarded as the most reliable and accurate method to test for color blindness, this hardcover book is published with permission from the foundation established by Dr. Ishihara.
