摘要
目的:探讨眩光对海军飞行员暮视视觉工效的影响。方法:在有或无眩光状态下,用视觉运动目标作业效能测试系统对28名海军飞行员进行暮视视觉工效测定,记录其辨认距离、辨认正确率和反应时。结果:在有眩光状态下,平均辨认距离缩短30%,正确率下降20%,反应时延长7%,与无眩光状态下比较均有统计学意义(P<0.05)。结论:暮视时,眩光对海军飞行员视觉工效有明显影响,应采取适当的防眩光措施。
Objective： To explore the influence of glare on twilight visual performance of naval pilots. Methods： Under the condition of existing or not existing glare, the twilight visual performance of 28 naval pilots were measured respectively by use of visual task efficiency testing system. The identification distance, correct percentage and reaction time were obtained. Results： Under condition of existing glare, the average identification distance shorted 30% （P〈 0.05）, correct percentage decreased 20% （P〈 0.05）, and reaction time protracted 7 % （P〈 0.05）. Conclusions： The effect of glare on twilight visual performance of naval pilots is significant. Proper measure against glare should be taken.
