【摘要】：目的测试和分析空军飞行员对比敏感度和立体视觉情况,以改进招飞体检中现行的视功能检查方法。方法应用美国StereoOpticalCo.生产的Optec、3500视觉检查仪和Titmus立体视觉检查图对33名(66眼)本科飞行员进行夜、夜+周边眩光、昼、昼+周边眩光四种状态下5个空间频率的对比敏感度和远、近距离立体视觉的检查。结果从95%可信区间和均数曲线图中可见夜和夜+周边眩光状态下对比敏感度曲线的峰值在3～6c/d;昼和昼+周边眩光状态下对比敏感度曲线的峰值在6c/d。近距离立体视觉均为40″(100%)的中心立体视。远距离立体视觉中心立体视为30名(90.9%),周边立体视为3名(9.1%)。结论对比敏感度和立体视觉检查在招飞体检及其他特殊职业人员的选拔和筛选中有重要的应用价值。
[Abstract]:Objective to test and analyze the contrast sensitivity and stereoscopic vision of air force pilots in order to improve the present visual function examination methods. Methods to apply American StereoOpticalCo. The contrast sensitivity and distance of 5 spatial frequencies of 33 (66 eyes) undergraduate pilots under four conditions of night, peripheral glare and daytime peripheral glare were studied by using the Optec,3500 visual examination instrument and Titmus stereoscopic vision chart. A close distance stereoscopic examination. Results from 95% confidence interval and mean curve, the peak value of contrast sensitivity curve in night and peripheral glare state was 3 ~ 6 c / d, and the peak value of contrast sensitivity curve in daytime and peripheral glare state was 6 c / d. Close distance stereovision was 40 "(100%) central stereopsis. 30 (90.9%) of the long distance stereoscopic vision centers and 3 (9.1%) of the peripheral stereoscopes. Conclusion contrast sensitivity and stereoscopic examination have important application value in the selection and screening of medical examination and other special professionals.
