A statistical study of visual functions and industrial safety

Abstract

Three accident groups (an accident-free group, a high-frequency-of-minor-accident group, and a serious-injury group) were compared as to average visual performance on the Bausch and Lomb Ortho-Rater. The accident-free group was found to be superior to the other two groups in far-vision acuity for both the right and the left eye, and also for the better and the worse eye. A composite of the 7 visual functions gave a CR between groups 1 and 2 of 2.69, and between groups 1 and 3 of 5.44. (PsycInfo Database Record (c) 2025 APA, all rights reserved)
