About
The HRR (Hardy, Rand and Rittler) Color Vision Test, 4th Edition, is a laminated pseudoisochromatic plate test for screening and assessing congenital and acquired color vision deficiencies in adults and children. It supports identification of protan, deutan and tritan deficiencies, covering red-green and blue-yellow color vision, and classification of deficiency severity as mild, medium or strong.
The test contains 24 plates: four demonstration plates, six screening plates and 14 diagnostic plates. The demonstration series introduces the task, the screening series assesses color vision, and the diagnostic series helps classify the type and severity of a detected deficiency.
Language-independent figures make the test suitable for adults and children without relying on reading numbers or words. A blank demonstration plate helps identify responses that may reflect memorization rather than recognition.
The plates feature non-glare lamination, tested using a spectrometer to confirm that the laminate does not alter the plate colors. The laminated surface helps protect the plates during handling.
