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。
In this study, healthy young people with normal eyesight as the test subjects, the use of different stroboscopic fluorescent lamp, visual fatigue occurs. The results showed that the changes of index of flicker-free DC fluorescent lamps, near point of eye adjustment, set point, flash fusion frequency and bright-eye duration were significantly smaller than those of stroboscopic fluorescent lamps after 8 hours of experiment. The difference was significant (P <0.05, P <0.01), suggesting that under the same conditions, no stroboscopic fluorescent light can reduce the degree of visual fatigue.
