This study explores the accuracy and specificity of an on-line version of a standardized colour vision deficiency test – the Hardy-Rand-Rittler test (HRR) performed in an uncontrolled environment. A group of 25 observers (18 with a colour vision deficiency and 7 with normal colour vision) that had previously been tested in a controlled setting participated, and the results from the on-line test was compared with previous results. The on-line test successfully predicted the main results of the physical test of all 25 observers. The test also predicted the deutans with an accuracy of 92 %.
