摘要
目的了解机车乘务员视觉功能特性,分析高速列车对其视觉功能的要求与变化。方法测定机车乘务员中心视力、双眼立体视觉、快速暗适应、色觉和视野等指标,并与对照组进行比较分析。结果年龄是影响机车乘务员视觉功能状态的主要因素,且呈负相关关系。结论高速列车对机车乘务员视觉功能的要求更高,尤其是中视力、快速暗适应能力与色觉功能。
Objective To study the locomotive drivers＇ visual function status and analysis the requirements and changes of high-speed train. Methods Measured and compared these indexes： central vision, stereovision, dark adaptation, color vision and visual field. Results Age is the major factors which affects the locomotive drivers＇ vision function and assumes the inverse correlation relations. Conclusion The requirements of high-speed train to locomotive drivers is more stricter than others, especially the middle distance vision, fast dark adaptation ability and color vision.
