摘　　要：设计了基于影动法的检影镜教学实验,通过中空反射镜旋转方向与观察到的视网膜成像光斑移动方向之间的动态关系,快速判断出模型眼视力屈光不正的类型,继而利用组合透镜成像原理实现待测模型晶状体的准确验光.通过本实验可加深学生对眼屈光不正视力检查原理的理解.A teaching experiment of retinoscopy based on spot motion method was designed.The ametropic type of the model eye lens could be quickly determined by using the dynamic relationship between the rotation direction of the hollow mirror and the observed moving direction of the retinal imaging spot.Furthermore,the accurate optometry of the model eye lens to be tested was also achieved according to the principle of combined lens imaging.This novel teaching experiment could deepen the students’understanding of the principle of ametropic examination.
