FIELD: medicine; ophthalmology. SUBSTANCE: test light stimulus is formed and shown to tested person in form of spatially light-nonuniform field. As standard light stimulus, the monochromatic field is shown, which substitutes pat of field of test light stimulus. Light stimuli are equalized by changing their mutual disposition till bringing standard light stimulus into contact with that part of field of test light stimulus where equality of chromaticity of stimuli is achieved from point of view of tested person. Co-ordinates of mutual disposition of stimuli are registered from which co-ordinates the quality of color vision is judged. To improve precision and to get more rapid determination of type of deviation of color vision, and to reduce time of measurement, several standard light stimuli with different chromaticity can shown to tested person. Method may be used for studying degradation or change in color vision during professional work and/or living. EFFECT: improved precision. |
