Detecting Color Blindness with Ishihara Plates
The Ishihara color vision test is a widely used method to detect color blindness, particularly red-green color deficiencies, such as protanopia and deuteranopia. The test consists of a series of plates, each containing a pattern of colored dots or numbers designed to be discernible to individuals with normal color vision but difficult to distinguish for those with color deficiencies.
