The HRR Colour Vision Test diagnoses congenital and acquired colour de\ufb01ciencies using simple shapes. It comprises a 6 plate screening section plus 14 detailed diagnostic plates to determine the type and extent of colour deficiency.<\/p>\n

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.<\/p>\n

Suitable for children aged\u00a03+.<\/p>\n

The test comes with an encapsulated matching card. You can purchase a separate matching card here<\/a>.<\/p>\n
