Abstract:
The effect of illumination on the contrast sensitivity function was studied using an Arden Contrast Sensitivity System and incandescent electric lamp. The intensities of illumination were set at 50,100,200,500, and 1,000 lx. The contrast sensitivity function was saturated at 500 lx of illumination in both monocular and biocular condition. But frequency charicteristics showed that the CSF was increased more at 1,000 lx of illumination at high frequency.
