Colour vision and tinted contact lenses

Abstract

The effect of tinted soft contact lenses on colour discrimination was studied using Ciba SoftcolorTM dark tinted lenses and the Lanthony New Colour Test for twenty subjects with normal colour vision. Blue, green, aqua and amber tinted lenses were used. We found no significant difference between test performance with the various tinted lenses and the clear lens which was used as a control. This result verifies, for a range of saturations, the conclusion drawn in a related study that tinted soft contact lenses do not affect the colour discrimination performance of persons with normal colour vision.
