Previous studies of the effects of color on the accommodation response are reviewed. The monocular,steady-state response to targets under various colors of illumination is investigated. It is shown that trainedobservers change their level of accommodation, when viewing a target at a constant distance, to compensatefor the varying ocular longitudinal chromatic aberration as the color of the target is changed. Untrainedsubjects, however, may initially show inconsistent responses. Results in white and green are closelycomparable. Dynamic aspects of these effects are illustrated and it is shown that the ocular longitudinalchromatic aberration increases slightly with accommodation. The results are related to current ideas on theaccommodative system.
