Ishihara 14 Plate

Primary Application: The Ishihara test is a simple, proven method for detecting congenital color vision deficiency (Protanomaly, Deuteranomaly, Dichromacy, Protanopia, and Deuteranopia). Color plates are encased in specially designed album-type books for ease of handling. 

Features:

• designed to produce accurate test results in determining color blindness and the degree of color blindness.
• The most accurate method of testing for color blindness still comes from official Ishihara album-type books.

Benefits: Although the full Ishihara test consists of 38 plates, usually the existence of a deficiency is obvious after a few plates. 

The Ishihara Color Testing Book is accepted by leading authorities as a simple and accurate method for discovering congenital color blindness and red-green blindness in both complete and incomplete forms. Also known as Protanomaly and Deuteranomaly, "red-weakness" and "green-weakness", respectively, are the two most common types of color deficiency.
