||Eye discomfort and work with visual display terminals
||Feb. 1994, Vol.20, No.1, p.27-33. Illus. 34 ref.
||A study involving 327 office workers was conducted by questionnaire and worksites were investigated in order to determine the relationship between eye discomfort symptoms and work with visual display terminals. The data were analyzed by multivariate logistic regression. The occurrence of eye discomfort increased as the extent of VDT work increased, as did the specific symptoms of sensitivity to light and smarting, gritty feeling, or redness. The use of spectacles during visual display work, age, stomach stress reaction, distances between the eye and different visual task objects, as well as the vertical position of the terminal also influence certain symptoms. Having (1) the terminal at about eye level during prolonged terminal work; (2) using monofocal glasses during terminal work in situations with large distance variations to visual task objects, or (3) being elderly with prolonged terminal work and reporting stomach stress, all led to increased odds ratios for certain eye discomfort symptoms. The use of a visual display terminal in routine office work is associated with an increased occurrence of certain eye discomfort symptoms. This association is affected also by the presence of certain other individual and ergonomic factors.
