Ishihara Color Testing Book

The Ishihara test is a simple, proven method for detecting congenital colour vision deficiency (protanomaly, deuteranomaly, dichromacy, protanopia, and deuteranopia).

Unlike the Ishihara patterns that may be found online and viewed on a computer monitor, this colour vision test is designed to produce accurate test results in determining colour blindness; and the degree of colour blindness. The 38 colour plates are encased in a specially designed album-type book for ease of handling.
