The Effect of Test Distance on Visual Contrast Sensitivity Measured Using the Pelli-Robson Chart
PURPOSE: The Pelli-Robson (PR) chart is widely used to measure clinical contrast sensitivity (CS). It is generally believed that PR testing distance is not critical. Here, we examine whether a closer test distance than the usual 1 meter might be better for patients with low vision. METHODS: PR CS wa...
