前言 适当的色觉在空勤人员选拔和飞行员操作中是一种重要因素,它取决于红(L)绿(M)和蓝(S)视锥的正常互补,遗传性红绿色盲是常见的(男性8％,女性0.5％),而蓝色缺陷是后天的,它是眼或全身疾病的早期征兆。在临床色觉检查主要发现色觉异常的存在而很少指出色觉缺陷的类型和严重程度。我们的目的是研制不同视锥的视力(VA)和对比敏感度(CS),并评 INTRODUCTION Proper color perception is an important factor in flight crew selection and pilot operation depending on the normal complementarity of the red (L) green (M) and blue (S) cones, which are common 8%, 0.5% of women) and the blue defect is acquired, which is an early sign of ocular or systemic disease. In the clinical color vision examination found primarily the presence of color vision abnormalities rarely pointed out the type and severity of color vision defects. Our aim is to develop visual acuity (VA) and contrast sensitivity (CS) for different cones, and to evaluate
