When a yellow minus blue is placed before an observers eyes most observers report an increase in brightness of the field viewed. This brightness increase occurs even though the radiant energy reaching the retinae is reduced. The magnitude of the effect is about 25 for filters customarily used for yellow goggles, and is restricted to photopic viewing conditions. This study examines the possibility that there may be a correlated improvement in acuity when the brightness of the field is enhanced by introducing yellow filters. Modified author abstract
