摘　　要：64名对象,年龄18～20岁,分为4组。在严格控制正常膳食摄入的情况下及补充复合微量营养素后,以血清维生素A(VA)、锌含量和快速暗适应恢复时间、微光近视力时间、绝对阈值为测定指标,观察受试人员机体暗适应功能变化,实验期14天。实验结果表明,补充足够剂量(生理需要量)维生素A,同时补充多种水溶性维生素和微量元素锌之后,人体暗适应功能提高效果更佳。由该复合微量营养素组成的制剂,可提供长期从事视力集中和低照度作业人员经常服用,以维持人体正常的暗适应功能,提高工作效率。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.
