摘要
采用透射式双变量对比视力表对398名现役健康男性军事飞行人员计796只眼，在200lx和6lX照度条件下检测了92％、52％、30％、11％和6％对比度兰道环视力，分析了对比视力值与年龄、机种、职务及飞行总时间的关系。结果表明：飞行人员的对比视力随年龄增长而逐渐降低，不随飞行训练时间的增加而相应提高，且不同的机种、职务间均无显著性差异。
Visual acuity were tested with transmission chart at illuminances of 200 lx and 6 lx withcontrast levels of 92 %, 52 %, 30%, 11 %,and 6 % in 769 eyes. It was found that contrast visual acuity ofpilots decreased with increase of age. No improvement was found with increase of training-time, andthere was no significant difference among pilots of different kinds of airplanes.
