Rapid Measurement of Contrast Sensitivity Using a New Contrast Sensitivity Vision Test Chart System: Initial Population Data

Contrast sensitivity functions of thirty-one young adults were determined using two recently developed chart systems. Resulting data were compared to data previously obtained with video display systems. Results indicate that the chart system can provide contrast sensitivity data similar to that obtained with microprocessor systems. Analysis of data from an additional license plate reading task produced significant Pearson product moment correlations between contrast sensitivities at 18 cycles per degree of visual angle and mean reading distance (r=.53, p<.05), and visual acuity (r=.53, p<.05), indicating that data obtained with the new chart system may be used to predict visual task performance. Since these charts are simple to use, require no calibration and little training, are relatively inexpensive, and provide immediate feedback on the correctness of the observer's response, these charts could be used to obtain contrast sensitivity functions for visual screening and job-related hiring standards.
