Abstract

Color is becoming important in the communication process of our technological society. A proportion of the population does not perceive color as the majority perceives it. This fact may lead to reduced communication, hindrance in the learning process, low performance on tasks which require acute color perception, and fatal judgements in situations requiring split second decisions based on color;Unless the color perception is deviant enough, this personal condition may be unrecognized until a medical examination;This study was designed to discover if a color microcomputer generated examination could be used to screeen for color perception difficulty and to assess the degree of agreement of this examination with an accepted color vision screening examination. The Cohen K coefficient of agreement between the Ishihara pseudoisochromatic plates and the color computer vision exam was computed. The Cohen coefficient of agreement of .72 indicated that the color computer has potential for use as an instrument to screen for color vision deficiencies. Further development of the computer procedure may permit self color vision screening at earlier ages for a larger proportion of the population.
