A review of the literature regarding visual performance with yellow lenses reveals little substantial evidence of visual enhancement with their use. However, several recent studies of contrast sensitivity with various filters have shown advantages for yellow over luminance-matched neutral filters. In this study, contrast threshold measurements were taken on 26 subjects using yellow, luminance-matched neutral, and clear control lenses using the Nic0let CS 2000 automated contrast sensitivity measuring system. No significant differences were found between any of the conditions at a.ny of the six spatial frequencies tested. Suggestions for further investigation are made.
