Ishihara's Test for Color Deficiency

Ishihara's 38 Plates Edition to test for various forms of color blindness

Details

Dr Shinobu Ishihara introduced in 1917 ‐ almost 100 years ago - the most well known color blindness test. Each of his tests consists of a set of colored dotted plates, each of them showing either a number or a path. Since then this is the most widely used color vision deficiency test and still used by most optometrists and ophthalmologists all around the world.
