目的:在民航招飞学员中研究屈光度预测远视力的模型,并初步探讨中国民航招飞远视力范围标准。
方法:收集1 219名中国民航飞行学院2006/2013年招飞体检学生的远视力和屈光度; 以屈光度为自变量,远视力为因变量拟合指数回归曲线模型; 依据模型计算不同屈光度对应的远视力预测值及其95%预测区间,并计算误差率,误差率=\〖(远视力预测值-实际均值)/实际均值\〗×100%。
结果:以屈光度(x)预测远视力(y)的曲线模型为:y=0.55e0.41x +e(R2=0.968),远视力预测误差率平均为3.64%; 屈光度\〖0.00,-3.00\〗D范围的远视力预测区间\〖0.14,0.55\〗与现行标准(0.3≤远视力<0.7)有交叉。
结论:该模型拟合效果良好,可根据屈光度预测合理的远视力范围。建议中国民航招飞时保持屈光度标准\〖0.00,-3.00\〗D不变,将远视力标准降至0.1。

AIM: To study the model to predict distant vision with diopter and to explore the distant vision standard for civil aviator recruitment in China.
METHODS: The data about distant vision and diopter of 1 219 students participating in physical examination of Civil Aviation Flight University of China from 2006 to 2013 were collected. A model of index regression curve with diopter as independent variable and distant vision as dependent variable was established. The predicted value and 95% prediction interval of distant vision to specific diopter were calculated according to the model. The error rate was calculated by formula: error rate= \〖(distant vision predicted value-actual average value)/actual average value\〗×100%.
RESULTS: The curve model with diopter to predict distant vision was: y=0.55e0.41x +e(R2=0.968). The average error rate of predicted distant vision was 3.64%. With diopter range \〖0.00,-3.00\〗D, the 95% prediction interval of predicted distant vision \〖0.14, 0.55\〗 didn't completely coincide with the current standard(0.3≤distant vision<0.7).
CONCLUSION: The fitting effect of the model is good and can be used to predict reasonable distant vision according to diopter. It is suggested to maintain diopter standard of China's civil aviation recruitment \〖0.00, -3.00\〗D unchanged, and drop the distance vision standard to 0.1.
