视网膜检影法是借用检影镜将光线照射在被检查者的眼内,通过摇动检影镜并观察角膜上的视网膜反光影的移动情况,用以测量屈光状态的方法。本检影方法具有简单价廉、结果客观准确、受调节因素影响小、适用范围宽的优点,是当前最为实用的客观验光方法。按其出射光线的不同分为平面 Retinal retinoscopy is the use of retinoscopy to light the light irradiation in the eye of the examinee, by shaking the retinoscopy mirror and observe the retina on the cornea reflex movement, to measure the refractive status of the method. The retinoscopy method has the advantages of simple and inexpensive, objective and accurate results, little influence by adjusting factors and wide application range, and is the most practical and objective objective optometry method currently. According to the different light rays are divided into plane
