Abstract

VDT syndrome has been understood as the outocme of the computerized socio-economic cultures in this modern age. It affects many workers on larious visual functions as well as affecting some general health conditions including neurologic, circulatory, and musculosckeletal system. We conducted series of investigations to evaluate the influence of VDT work on the physiologic functions using objective ocular examinations on VDT workers with non-VDT workers as controls. Prolongation of near point decreased accommodation amplitude, myopic shift of refractive condition, and decreased amout of tear formation were significantly indicative in the VDT workers' group. The above functional disturbances can significahtly, deteriorate not only working effeciency but general physical condition if appropriate measures are not provided quickly. Therefore, it is firmly suggested that a comprehensive epidemiological study should be implemented aimed at ImprovIng working situations for VDT workers.
