飞行人员夜间视力的好坏直接关系到夜间飞行的成功与安全。缺氧又是降低夜间视力的重要原因。以往国外资料多认为在5000米高度以上缺氧时影响显著,对3000米以下的报导较少,我国更缺乏这方面的资料。为了探索轻度缺氧对夜间视力的影响,从而为夜间飞行提供合理供氧高度的根据。我们于1981年对空勤体检合格的21～40岁,平均飞行810小时(夜间平均飞行60小时)的男性飞行人员120名,就轻度缺氧对人眼睛适应和夜间视力的影响进行了实验研究。
The night vision of pilots is directly related to the success and security of flight at night. Hypoxia is also an important reason to reduce night vision. In the past, many foreign countries believed that they had a significant impact on hypoxia at a height of 5,000 meters or less and reported less than 3,000 meters, which was more lacking in our country. In order to explore the impact of mild hypoxia on night vision, so as to provide a reasonable basis for night flight altitude oxygen basis. We conducted a pilot study of the effects of mild hypoxia on human eye accommodation and night vision in 1981 for 120 to 40-year-olds with an average of 810 hours of flight (60 hours average night-time flight) .
