This study investigated actual conditions in computer use as well as computer use-related problems. A survey was conducted through a computer network. A great majority of a total of the 3,287 respondents were young and skillful users. However, two-thirds reported musculoskeletal troubles and one-third complained of psychological problems. Users' troubles increased with operation time and when computer use shifted from hobby to work. Eye troubles were frequently reported regardless of the length of operating time or purpose. In general, females complained of eye and musculoskeletal discomforts more often than males although no gender differences in psychological problems were observed. Mouse use-related discomforts were inconclusive because only 10 % of respondents mainly use the computer mouse at present.
