How is color deficiency detected?
People who are color deficient are generally unaware of their condition. They assume that everyone sees things the way they do. As a result, a complete optometric examination, including a test for color vision, is recommended. The test for color deficiency is a relatively simple one, typically involving the viewing of a series of colored designs. The designs have been created in such a way that a person with normal color vision can see certain figures in the designs. A color deficient person will not be able to distinguish the figures.
