Eye problems and visual display terminals--the facts and the fallacies

Abstract

Estimates of the prevalence of eye problems associated with using visual display terminals (VDTs) vary enormously depending on the sample tested and the research methods employed. However, most authors agree that eye problems are common among VDT users. In this paper, the relative contributions of the nature of VDT displays, workstation design, work-practices and optometric factors are discussed, drawing from the substantial body of literature which now exists on this subject.

Ergonomics standards and guidelines for computer workstation design and the impact on users’ health – a review

“…Nevertheless, this enormous change is accompanied by an increase in complaints associated with health problems. Concerns over musculoskeletal and visual disorders related to computer use (Bergqvist et al, 1995a(Bergqvist et al, , 1995b; Thomson, 1998) Today, several types of ergonomics standards and guidelines are in existence worldwide, including national legislation, international and national standards, national guidelines issued by government agencies or voluntary standards organizations, and technology agreements between companies and trade unions. The flow of events, including the creation of standards, ordinances, and guidelines, the occurrence of visual display terminal conferences, inspection audits, and the publications of technical papers between 1972 and 1990, are summarized in Table 1.…”

Marked reduction and distinct patterns of eye blinking in patients with moderately dry eyes during video display terminal use

“…The increased frequency of video display terminal (VDT) use has been accompanied by an increased number of health problems [16]. Frequently reported complaints are ocular fatigue, eye strain, eye burning, tearing, and foreign body sensation [4,13].…”

“…The increased frequency of VDT use has been accompanied by an increased number of health problems [16]. Many persons report the occurrence of dry eye symptoms (e.g.…”
