The International Colour Vision Society (ICVS) is an international group of physiologists, psychologists, physicists, geneticists, optometrists, ophthalmologists and visual scientists who have a research interest in the many aspects of colour vision and colour vision deficiencies.

Brief History of the Society

The Society began its existence as the International Research Group for Colour Vision Deficiencies (IRGCVD), and was conceived by a group of clinicians and visual scientists during the AIC Congress held in Stockholm in 1969. Its first formal meeting, in Ghent in 1971, was devoted to acquired deficiencies of colour vision.

Guy VerriestIn its early years, the mainstay of the IRGCVD was the Belgian ophthalmologist Guy Verriest (1927-1988), who acted as both Secretary and Editor. In 1991, a special award was bestowed by the Society to honor long-term contributions to the field of colour vision in his name to recognize his contribution to the Society.

The IRGCVD changed its name to the International Colour Vision Society in 1997, to recognize that presentations on the basic mechanisms of colour vision were increasingly prominent at the biennial meetings.
