Computer implemented colour vision test and method of calibrating the computer implemented colour vision test

Abstract

Method of calibrating a computerised colour vision test and method of testing colour vision on a computer The invention relates to a method of calibrating a colour vision test for testing colour vision under given ambient lighting conditions, which colour vision test is to be displayed on a colour display () of a computer () having at least one input interface (), characterised by displaying a calibration test on the display () under given ambient lighting conditions to a person with normal colour vision before starting the colour vision test, displaying within at least one measuring region () of the display () a colour determination task requiring user input as a part of the calibration test, reading the user input through at least one input interface () of the computer (), evaluating the read user input and determining as a result of the evaluation a display error resulting from a combination of a colour reproduction capability of the display () and an effect of the ambient lighting conditions on colour vision, and determining a modification to the colour vision test from the display error that corrects the colour vision test with respect to the display error. The invention further relates to a method of testing colour vision using the calibration method, as well as to a computer and computer program configured for performing such methods. The invention further relates to a colour discrimination test, to a colour identification test and to a combination of the two tests.
