The Adult Diagnostics is from the Waggoner Computerized Color Vision Test and has a total of 4 sections and consists of pseudoischromatic plates. This test is adaptive, randomized, and completely self-administered to reduce administrator bias. Depending on how an individual performs on the General Screening section, they may continue onto sections 3 and 4, after which a color vision diagnosis will be provided. The test-taker will be able to view the plate images for a total of 3 seconds each followed by 8 more seconds to answer. A demo plate will be presented prior to beginning the scored test.
