COLOUR VISION TESTING: SCIENCE OR JUST BAD HABITS?

Abstract Colour vision testing has been and remains a controversial subject in aviation. Despite this, colour testing methods have remained essentially unchanged in many years. This presentation reviews the relevance of colour testing methodologies to modern aviation and presents a review of recent literature relating to colour vision and how it is affected by various physiological states and changes occurring with various pathological conditions; and the relevance of these discoveries to current and future aeromedical certification processes.
