Summary.

In order to evaluate the effects of dietary taurine supplementation on visual fatigue induced by visual display terminals (VDT) work, 25 male college students aged from 20 to 24 years who were not engaged in VDT work were selected to participate in the study. Volunteers were randomly assigned to either the taurine supplementation (n=13) or the placebo supplementation control group (n=12). Before and after 12 days of taurine (3 g/day) or placebo supplementation, two identical 2.5-hr VDT work tests were performed while recording the P100, N75 and N145 latencies and P100 amplitude of pattern visual evoked potential (PVEP) and the frequency of critical flicker fusion (CFF). Following 2.5-hr of VDT work, the P100 and N75 latencies of PVEP increased (P<0.01) while the P100 amplitude decreased significantly (P<0.01). The frequency of CFF also reduced significantly (P<0.01). After 12 days of taurine supplementation, the reduction in P100 amplitude after VDT work alleviated significantly (P<0.05). The results suggest that taurine supplementation alleviates visual fatigue induced by VDT work.
