Abstract
We studied the influence of different stimulation parameters on the results of automated color vision examinations. Color vision was tested with the red-green Rayleigh equation and the blue-green Moreland equation on six normal observers with our computer-controlled anomaloscope. Results demonstrate that (1) it is important to vary automatically the radiance of the test field to provide an approximate luminance match as the ratio of primaries in the mixture field is changed; in doing this, subjects can concentrate on hue balance between the two half-fields and are not disturbed by a simultaneous luminance mismatch. (2) In agreement with Moreland & Kerr (1979), the saturation of the test field in the Moreland match can be preset to a fixed value. (3) Matching range varies with exposure time, showing a flat minimum in the region of 1 s for experienced observers. A time of 2–3 s was adopted for clinical work.
