Ishihara Color Test 14 Plate Edition

The Ishihara color test is recognized internationally as a highly reliable method of determining color vision deficiency. Made in Japan by Kanehara, this original Ishihara 14 plate color test is an industry standard. With normal color perception, the images and numbers will be visible. With color deficiency, a different number or none at all will appear. Each color test plate in this hard bound book is specially printed to measure incrementally higher color sensitivity and specificity. The Ishihara Color Test is available in 14, 24, or 38 Plate Editions.
