VDT syndrome is the disease entity that affects many workers on the various visual function as well as on some general health conditions including neurologic, circulatory and musculoskeletal system and it tends to increase day by day. We performed a series of investigation to evaluate the influences of VDT work on the subjective symptoms by means of questionnaire application with the control of non-VDT workers. It revealed that the susceptibility in occurrence of impairment of ocular functions like asthenopia as well as the disturbances of musculoskeletal circulatory, gastrointestinal, and nervous systems were more pronounced in the VDT workers' group than the control group, and the environmental factors like working hours, air pollution, and noise also contributed for the worsening of the ocular and systemic symptoms. It is suggested that the improvement of operating environment by the implementation of comprehensive epidemiological study in association with the improvemental task of working situations and working times in long term advocated would decrease the VDT syndrome among VDT workers.
