The influence of lighting of different spectral power distribution on letter contrast
sensitivity has been studied. The different spectral power distributions were
obtained by filtering or dimming tungsten halogen lamps. Measurements were
made on 20 young and healthy individuals (25 eyes) whose monocular contrast
sensitivities were measured with a natural pupil. Sixteen combinations of test and
surround luminance with high or low correlated colour temperatures were
studied in such a way that the influence of test luminance, surround luminance or
colour temperature of both visual fields could be independently studied. Both test
luminance and surround luminance influenced contrast sensitivity but correlated
colour temperature did not.
