Abstract:
The effect of micronutrient complex preparations on dark adaptation function was studied in human body. Sixty-four young students, 18 to 20 years of age, were divided into four groups. Under the normal dietary condition, the experimental groups were supplemented with different microcutrient complex preparations for two weeks.Before and after the experiment serum vita- min A and zinc level, quick dark adaptation time, near-sighted in dim light time and absolute threshold were determined. It was found that dark adaptation was much improved in the group supplemented with adequate vitamin A as well as other vitamins and zinc. So we suggested that micronutrient complex preparation should be given to operators who will concentrate their sight in low illuminance for maintaining their visual function.
