--- It was done a study with cuantitative design, descriptive, type cross sectional of sample of 66 visual data terminal operators of the National Hospital Guillermo Almenara Irigoyen (HNGAI) among February and June 2003. Objective: To determine the association among time of exposure to visual data terminal (VDT) and visual fatigue in this group. Methodology: We identified whom had inclusion and exclusion criteria for study, reviewed their occupational clinical histories elaborated by the Unit of Occupational Health HNGAI, verifying records of ophthalmological pathology. In their workplace, it was applied an specific questionnaire for symptoms of visual fatigue and a basic ocular clinic exam, in the start and end of shift work did them. Complementary, measurement of lighting on work surface and on VDT, viewing distance and other for calculate viewing angle were did it. Outcome: Prevalence of visual fatigue was 59% in this group. For other variables of study, multivariate analysis showed a significant association among time of exposure to VDT and visual fatigue (p=0.009) (RP=1.4). Conclusion: The probability of visual fatigue increase with prolonged exposure to VDT in the workplace. Keywords: Visual data display, Visual fatigue, computer operators, hospital
