Effect of Tinted Contact Lenses on Color Vision

This study was designed to investigate the effects of various contact lens tints on color vision. Color vision performance of eight subjects was eualuated with the Farnsworth‐Mun‐sell 100 Hue Test while each subject wore each of 13 differently tinted contact lenses. No signif‐icant differences in color vision were found with the various lenses. However, performance on the test was affected by repetition. Regardless of the lens tints tested, color discrimination for the blue quadrant of the 100 Hue Test was the poorest. Further research is needed to determine the effect of tinted contact lenses on scotopic and mesopic vision.
