The HRR (Hardy Rand and Rittler) Standard Pseudoisochromatic Test, 4th Edition provides several very important features to provide the most advanced Color Vision, test available: congenital and acquired testing, identification of the type of defect and diagnosis of the extent of the defect as well as quick positive classification of normals. The HRR employs a sophisticated test strategy that virtually eliminates the potential for memorization and malingering. The figures used by the HRR Pseudoisochromatic Plates are independent of language and suitable for both adults and children.
The Lanthony Desaturated Color test is identical to the Farnsworth D-15, but the 15 disks are desaturated (lighter in hue). This allows the screener to determine whether or not the subject has the ability to discriminate between subtle color variations. The test can distinguish between normal color perception and mild deficiency in protan/deutan (red-green) or tritan (blue-yellow).
Color Vision, Testing Made Easy (CVTME) is the pediatric gold standard for identifying genetic (red/green) Color Vision, deficiencies in children as young as 3. It consists of one demonstration plate and 9 test plates displayingcircle, star, and/or square throughout the platesand can be completed in under 60 seconds.
On most plates, children will be able to see at least one symbol even if they are Color Vision, deficient. If they can’t identify one symbol on the first few plates, they may not understand the test. In addition, CVTME provides a quick screening by using 4 cards that have a car, dog, boat, and house. This test can be completed in less than 30 seconds. CVTME is brilliantly simple to take and just plain fun for children. Considered the gold standard for pediatric assessment of Color Vision, deficiencies in over 40 countries. Additionally, the “World” US Special Olympics Team have depended on CVTME to screen athletes over the years at their events.
