Title Correlates of ocular and somatic symptoms among video display terminal users
Bibliographic information Apr. 1984, Vol.26, No.2, p.143-156. 30 ref.
Abstract A cross-sectional survey was conducted among employees of a newspaper company to define the type of ocular and somatic complaints reported by video-display terminal (VDT) users and to identify their relationship to VDT use, to determine the association between symptoms and the participants' adequacy of correction of refractive errors for their jobs and to assess the prevalence of eye abnormalities, especially cataracts, and their relation to VDT use. Poor visual clarity of the VDT screen explained the plurality of work-associated symptoms. 1 qualitative and 2 quantitative VDT-use variables suggested that lesser skill or experience were associated with headaches. No associations were found between adequacy of the participants' refractions, including the wearing of glasses with bi- or multifocal lenses, and the reporting of work-associated symptoms, nor between VDT use and the prevalence of eye abnormalities.
