About the authors
Anthony Spalding graduated in medicine from London University. He worked for two years in paediatrics, got diverted to research for a while and then worked as a general practitioner in east London for twenty-five years. He is colour blind: he has the colour deficiency of deuteranopia. He has done research on abnormal colour vision in relation to the practice of medicine and has published a number of papers on the subject. His experiences in clinical work led him to realise that there are many in the same position as himself and that abnormal colour vision has implications for the medical profession that should not ignored.
Barry Cole is Emeritus Professor of Optometry at the University of Melbourne in Australia. One of his many research interests has been the practical implications of colour vision deficiency in everyday life and at work, a subject on which he has published numerous papers. This started because of an early interest in visual ergonomics, which is the field of designing tasks to fit the visual capabilities of the people who have to do those tasks. Among other things this means making a careful choice of colours for signal lights and other colour codes so that they can be recognised, as far as is practical, by people with abnormal colour vision.
Fraz Mir is a consultant physician in medicine at Addenbrooke’s Hospital, Cambridge. His interest in colour vision abnormalities in medicine was stimulated by involvement in a related research project as a student in London.
