The HRR Colour Vision Test diagnoses congenital and acquired colour deficiencies using simple shapes. It comprises a 6 plate screening section plus 14 detailed diagnostic plates to determine the type and extent of colour deficiency.

The first four plates are used to show the patient how the test works. The next six plates (screening series) present the most difficult yellow, blue, red, and green colours. Success with these plates defines the subject as having ‘normal colour vision’ and completes the test for that person. The subsequent 14 plates (diagnostic series) cover all four colours and provides diagnostic as to the extent (mild, medium or strong) and type of defect (Protan, Deutan, Tritan). The 4th Edition of the HRR Colour Vision Test has been proven effective in more than six different clinical trials to date. Please see the More Details tab for further information.

Suitable for children aged 3+.

The test comes with an encapsulated matching card. You can purchase a separate matching card here.

More Details

The HRR test uses simple figures which can be located in any quadrant on each plate. This combination is virtually impossible to memorise, unlike Ishihara-type numbers based tests and is suitable for testing pre-school children. Plates are numbered for scoring on the reverse and each page is tabbed for easy selection and to help keep the pages clean.

The paediatric version has laminated pages (colours verified with a Spectrometer) to avoid damage from little fingers and protect the pages for years of use. Also included is a set of matching cards, instructions, and reproducable score sheet.

A version with 4 Amsler grids is also available. Price and information on request.

“I use the HRR in preference to Ishihara or anything else as I find it user friendly and achieves what I want, which is to identify acquired colour loss. I am not really interested in inherited loss, although it will do that too. I find the test plates very useful so that young patients in particular can work out what they need to do. The presence of the screening plates makes the test much quicker than Ishihara if normal. The presence of yellow blue is helpful in acquired colour defects as well as in the odd red green colour blind patient who you might want to look for a superimposed acquired defect.”
