【摘要】 本研究以视力正常的健康青年人为受试对象，测试使用不同频闪的荧光灯时，视觉疲劳出现的情况。测定结果表明，经８小时实验观察，使用无频闪的直流荧光灯，眼的调节近点、集合近点、闪光融合频率、明视持久度等指标的变化程度，明显小于有频闪的荧光灯，差异有显著性（Ｐ＜０．０５，Ｐ＜０．０１），提示在同样条件下，无频闪的荧光灯可以减轻视觉疲劳程度。更多还原

【Abstract】 The asthenopia after using 4 types of fluorescent lamps with different flicker rate was examined.7 male and 9 female healthy subjects with normal vision were selected.Indicators such as near point of accomandation,near point of convergence and the flicker fusion frequency and so on were examined.The resutls showed that significatn difference( P <0 05 or P <0 01) existed among different flicker rate.The fluorescent lamp of direct current is the best one.It suggested that asthenopia might be reduced by using non flicker fluorescent lamp.更多还原
