Pediatrics Norms for Visual Contrast Sensitivity Using an APT VCS Tester

Abstract

This graph plots spatial frequency measured in CPD (cycles per degree of visual arc) against the average number of correct responses before an error (raw score) in each frequency. "І" designates 1 and 2 standard deviations at each CPD. Diagram 3 Key: This graph plots spatial frequency measured in CPD (cycles per degree of visual arc) for boys and girls against the log of the contrast sensitivity at each frequency. "І" designates 1 and 2 standard deviations at each CPD.
