The 23 plate Waggoner HRR Color Vision test detects, classifies, and estimates the degree of protan (red), deutan (green), and tritan (blue) color vision deficiencies in all age groups. Objects such as stars, circles, triangles, crosses and square can be easily identified and it takes just one minute to administer and score. Everyone, including colorblind individuals, see one object on the first eight cards. This test for malingering and validates they understand your instructions and are trying their best.
