The object of the invention relates to a method of designing a colour filter for modifying human colour vision by defining the spectral transmission function of the colour filter such as to maximise colour discrimination between more than one element, colour sample, of a colour sample set when a targeted human eye, the colour vision of which is to be modified, is viewing the colour sample set with the colour filter, and at the same time such as to minimise the difference between the colour identification of the colour samples by the targeted eye and a reference eye having a reference colour vision. The object of the invention also relates to such a colour filter, such a colour filter set, and the use of such colour filter and a method for modifying human colour vision.

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.
