ABSTRACT Currently, there is intense clinical, commercial, and academic interest in the potential value of the contrast sensitivity function (CSF) for detecting eye disease. This paper contains an evaluation of the CSF as a screening test. Questions are raised concerning its scoring, accuracy, reliability, and robustness in screening situations. We conclude that the CSF cannot be of much value in visual screening until these questions are answered.
