Abstract
A study tested the variability and reliability of modern psychophysical tests using computer graphics systems with cathode ray tube displays. Luminance and color contrast sensitivity was measured in 2 sessions in the macula and peripheral retina of 28 normally sighted women. Individual variations of the tests were considerable, testretest variability was small, and there was a strong correlation between thresholds for different tests. The influence of age was small. The "noise" of the test was less than the threshold's normal variation.
