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。
The purpose is to examine the impact of glare on visual function of naval pilots. Methods Totally 256 HNA pilots were tested for glare using a multi-functional glare visual detector. Pilot normal CSF and glare disability (GD values) were measured in both glance and twilight conditions. Results Under the experimental conditions, the frequency band of conventional CSF was the most sensitive, followed by low frequency, while the high frequency was the least sensitive. GD was about 7.9% ~ 16.2%, but there was a big difference between the two groups. In GD, the value of GD was much larger than that of SD (about 23.1% -61.8%), and the individual The difference is relatively small. Conclusions Glare disability at nightfall is more detrimental to flight safety.
