The new Richmond HRR pseudoisochromatic test for colour vision is better than the Ishihara test. Richmond Products produced a new edition in 2. This study is a validation trial of the new test using a larger sample and different criteria of evaluation from those of the previously reported validation study. METHODS: The Richmond HRR test was given to 1. Colour vision was diagnosed using the Ishihara test, the Farnsworth D1. Medmont C- 1. 00 test and the Type 1 Nagel anomaloscope. RESULTS: The Richmond HRR test has a sensitivity of 1. Sensitivity and specificity become 0. Those with red- green colour vision deficiency were correctly classified as protan or deutan on 8. All those graded as having a 'mild' defect by the Richmond HRR test passed the Farnsworth D1. Not all dichromats were classified as 'strong', which was one of the goals of the re- engineering and those graded as 'medium' and 'strong' included dichromats and those who have a mild colour vision deficiency based on the results of the Farnsworth D1. CONCLUSIONS: The test is as good as the Ishihara test for detection of the red- green colour vision deficiencies but unlike the Ishihara, also has plates for the detection of the tritan defects. Its classification of protans and deutans is useful but the Medmont C- 1. Those graded as 'mild' by the Richmond HRR test can be regarded as having a mild colour vision defect but a 'medium' or 'strong' grading needs to be interpreted in conjunction with other tests such as the Farnsworth D1. The Richmond HRR test could be the test of choice for clinicians who wish to use a single test for colour vision.

A leaflet is a miniature web site which can be created online and distributed through an URL or an embedding link. I thought this could be a great way to show the 3. Ishihara plates to test your color blindness. All plates show a big circle consisting of many little colorful circles. Color Blind Testing Guide for Pilot Applicants. AOC-HRR (second edition) Dvorine pseudoisochromatic plates.Because the circles differ in color and brightness it can get really tough for a colorblind person to see the shown numbers or traces. If you take the following color blindness test be aware that those pictures were scanned and are now reproduced by your display. This can alter the colors. Because a color blindness test relies solely on correct color reproduction you shouldn’t take the results for granted. If you really want to check your color blindness you should see your local doctor. Could you perform as you expected? Or did the plates show that you really are red- green colorblind? I hope you could spot at least the number in the first and the trace in the last plate, otherwise you may have a real severe color vision problem. Previous Edition Obsolete.
