Because computer use is such a high visually demanding task, vision problems and symptoms are very common. Most studies indicate that computer operators report more eye-related problems than noncomputer office workers. A number of investigators (Smith et al., 1981; Yamamoto, 1987; Dain et al., 1988; Collins et al., 1991) have indicated that visual symptoms occur in 75 to 90% of computer workers. In contrast, a survey released by the National Institute for Occupational Safety and Health (NIOSH) showed that only 22% of computer workers have musculoskeletal disorders.
