目的：调查民航飞行员视频终端疲劳综合征(visual display terminal syndrome，VDTS)的现状并分析其原因，为民航飞行员眼部保健工作提供依据。方法：对1 631名民航飞行员进行问卷调查，了解暴露时间，比较不同暴露强度人群的不适症状和发病率。结果：民航飞行员视频终端暴露时间为(4.43±2.24) h，VDTS发病率和不适症状检出率均随暴露时间增加而增加。结论：长时间视频终端暴露不利于眼健康。应加强对民航飞行员的眼保健教育，避免或减少视频终端暴露带来的健康危害。

Objective: To investigate the status of visual display terminal syndrome (VDTS) in civil aviation pilots and analyze the causes, so as to provide evidence for eye health care of pilots. Methods: A questionnaire survey was conducted among 1 631 pilots to understand the exposure time and to compare the incidence rate of discomfort in participants with different exposure intensities. Results: The average exposure time of pilots’video terminals was (4.43±2.24) h. The incidence rate of VDTS and the detection rate of discomfort increased with the increase of exposure time. Conclusion: Prolonged exposure to video terminal is not conducive to eye health. The eye health education for pilots should be strengthened to avoid or reduce the health hazards caused by video terminal exposure.
