Title VDT work, oculomotor strain and subjective complaints: An experimental and clinical study
Bibliographic information Aug. 1994, Vol.37, No.8, p.1419-1433. Illus. 38 ref.
Abstract In an experimental study, two groups of workers performed three hours of continuous VDT work, one group watching the visual display and the other looking out of the window. There were significant group differences in work-related effects on the eyes' ciliary and extraocular muscles and on subjective symptoms; not only visual symptoms but also muscle pain in the head, neck and upper back may result from near-point induced oculomotor strain. The effect of optical correction was examined in 14 symptomatic workers. There was a significant reduction in symptoms, indicating that visual anomalies contribute to work-related symptoms.
