METHOD OF DESIGNING A COLOUR FILTER FOR MODIFYING HUMAN COLOUR VISION, SUCH COLOUR FILTER AND COLOUR FILTER SET

摘要

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.
