摘　　要：目的为考察眩光对海军飞行员视功能的影响。方法对２５６名海航现役飞行员用多功能眩光视觉检测仪进行了眩光试验。检测了飞行员常规ＣＳＦ以及在明视和暮视有眩光条件下的眩光失能值（ＧＤ值）。结果在本试验条件下常规ＣＳＦ中频段最为敏感，低频次之，高频最不敏感。明视ＧＤ值约在７．９％～１６．２％之间，但个体差异较大；暮视时ＧＤ值远比明视时大，约为２３．１％～６１．８％，且个体差异相对较小。结论在暮视时眩光失能对飞行安全危害更大。Objective To study the effect of glare on visual function.Methods The subjects were 256 navy pilots on active service. Glare test was investigated with a multivision glare tester. The routine contract sensibility function (CSF) and glare disability (GD) value were measured in photopic and twilight conditions with glare.Results The routine CSF was most sensitive at middle spatial freqencies than that at low or high frequencies. And GD values in photopic condition were about 7.9%～16.2% with considerable individual difference.In twilight condition GD values were higher than those in photopic condition (about 23.1%～61.8%).Conclusion Glare disability in twilight condition is more dangerous for flying safety.
