This summary discusses issues raised at a National Research Council symposium on vision and VDT work, held at the request of the National Institute for Occupational Safety and Health. Symposium participants critically reviewed laboratory studies of visual function and field surveys of visual complaints of VDT operators to determine what conclusions can be drawn about the prevalence, severity, causes of, and possible remedies for reported difficulties. Although speakers' perspectives differed, a number of points appeared to gain consensus: (i) properly designed epidemiologies) studies comparing the incidence of visual problems in VDT operators with that in non-VDT workers are needed, (ii) Visual issues are closely interrelated with ergonomic and job design variables, and use of multivariate statistical analysis is necessary to determine what specific aspects of work involving VDTs may contribute to visual and other complaints, (iii) No scientifically valid study has established that VDT use causes harm, in the sense of damage, to the visual system, (iv) Existing knowledge indicates a number of measures that could be taken to improve worker comfort and performance: use of high-quality displays; control of workplace lighting conditions; application of principles of anthropometric design; and consideration of workers' needs in design of jobs, (v) Surveys of radiation emissions from VDTs indicate that levels of radiation are far below U.S. occupational exposure standards. Published data provide no evidence that cateracts are associated with VDT use. (vi) Standards should be based on research. Differing opinions on whether setting standards is useful and appropriate point to the need for caution in this area. Needs for further research were identified. |
