Please Note: This Ishihara Colour Vision Test is provided by Dr. Terrace L. Waggoner from http://colorvisiontesting.com/ishihara.htm#first test plate
Due to the fact there are so many different monitor screens displaying different colors, the accuracy of this “on-line” color vision test is limited. This webpage is for “screening” purposes only, not a “diagnosis”. For a diagnosis, you should see your vision care professional and be given the complete test using all 24 plates of the “PIPIC” under controlled testing conditions and the proper lighting. To order the complete test in book form click on the below picture. Please let the distributor know you were referred by Dr. Waggoner.
