Title

Maintenance Of Correct Accommodations In Red, Green, And White Light Environments

Abstract

This project explored the practical importance of ambient color as a concern for maintaining human visual accommodation. Correct accommodation and regression toward resting point accommodation were considered in broadband red, broadband green and white environments. The involvement of voluntary control of accommodation was manipulated by requiring extended performance on a difficult visual task across four light levels. Declining light levels and increased time-on-task were found to degrade the accuracy of accommodation, while manipulation of ambient color produced differences attributable to chromatic aberration. Differential abilities associated with red, green or white conditions were not apparent, as no statistically significant interactions were evidenced. Results of these and other related findings generally suggest that, allowing for chromatic aberration of the lens, the human eye maintains visual accommodation equally well across varied color conditions. Maintenance of correct accommodation and regression to the resting point of accommodation do not appear to be influenced by ambient color.
