Abstract

There is a decrease in sensitivity to high spatial frequencies with aging which becomes significant above age 50⁽¹⁾. Repeating this study with a greater number of subjects, we have found a small but significant difference between subjects aged 20-30 and those 31-40⁽²⁾. One possible explanation of the loss of sensitivity in this relatively young population is a gradual increase in the light scattering properties of the ocular media increasing disability glare⁽³⁾. The purpose of this ongoing study is to test the hypothesis that the effect of disability glare on contrast sensitivity increases with age.
