•  Color vision tests that consist of different colored circular dots are all called pseudoisochromatic color vision tests. The Ishihara, Divorine, and this online Waggoner PIPHRR color vision test are all pseudoisochromatic color vision tests. This test is not the Ishihara but it is a pseudoisochromatic color vision test. The Waggoner PIPHRR computerized test is considered Ishihara compatible.

Color vision test booklet, such as the Ishihara, only screen for color vision deficiencies. A screening tool gives a person a "yes" or "no" result. The Waggoner PIPHRR gives a diagnosis. A diagnosis tool tells people if they have a color vision deficiency, what type of color vision deficiency they have (deutan, protan, and/or tritan), and how severe it is (mild, moderate, or severe). Here are several other reasons why the Waggoner PIPHRR online test is better than a booklet:

- Standardization of the test where each person is given the same time interval on each test plate and no cues from a person administering a test.

- Test can be taken anywhere there is a computer and internet.

- Test can be taken at any time that is convenient to the test-taker.

- Nobody has to administer the test.

- The test takes approximately 3 - 6 minutes compared to the 10 minutes of traditional booklet tests.

- Cannot memorize the test because the test plates are randomized each time the test is taken. Automatic test results.

- Test can be sent to 1000s at once via email Increases productivity for an organization when testing multiple people. Color vision test booklets fade over time making them invalid.

- You can use your current computer and there is no need to purchase any new equipment.

• The test has proven itself reliable but it is still in the early stages of validation. The developer of the Waggoner PIPHRR color vision test, Dr. Terrace L. Waggoner, has created several other color vision tests that have been validated; Pseudoisochromatic Plate Ishihara Compatible 24 Plate Edition and Color Vision Testing Made Easy. The same proven confusion colors used in these validated color vision tests are also used in the Waggoner PIPHRR. Research is currently being done by several different organizations some of which include:

• Naval Aerospace Medical Institute (NAMI), Pensacola, FL
• Federal Aviation Administration (FAA), Oklahoma City, OK
• Southern California College of Optometry (SCCO) Fullerton, CA
• Naval Medical Research Unit-Dayton Wright -Patterson AFB, OH
• Southern College of Optometry, Memphis, TN

- U.S. Navy

- U.S. Army

- Kaiser Permanente

- Core Medstaff

The Waggoner PIPHRR is also being used in several studies being performed by Ph.Ds.

The viewing time of the Waggoner Pediatric PIPHRR has been increased to give pediatric/geriatric subjects more time to respond compared to the Waggoner PIPHRR. The answer selection is on the same page as the test plate on the Waggoner Pediatric PIPHRR.

Absolutely. Our software development team would be more than happy to work with you developing a color vision testing module that works with your learning management system.

Naval Aerospace Medical Institute is currently comparing it to a 14 PIP test, Farnsworth Lantern, Richmond HRR, and a Nagel Anomaloscope. Preliminary finds have found it more reliable that the PIP, Farnsworth Lantern, and Richmond HRR.  The Waggoner PIPHRR is 100% in agreement as far as the type of color vision deficiency with Nagel Anomaloscope - the gold standard for evaluating color vision tests.

There are numerous industries that either require or recommend normal color vision. A list of these industries and occupations can be found on our website here near the bottom of the page.
