A new principle of retinoscopy proposes that the endpoint of neutralization be placed at infinity rather than into the aperture of the retinoscope. The advantages of the method are (1) the pupillary reflex is sharply defined and enhanced at neutralization, (2) the pupillary reflex width is equal to the diameter of the smallest aperture of the observation system, (3) the relative speed of the pupillary reflex is equal to 1, that is, the speed of the reflex is that of the scanning speed, and (4) neutralization at infinity is independent of the observation distance. The lens used gives the "net" retinoscopy.
一种新的检影验光原理提出，中和终点应置于无穷远处而非检影镜的孔径处。该方法的优点在于：（1）中和时瞳孔反射清晰界定且增强；（2）瞳孔反射宽度等于观察系统最小孔径的直径；（3）瞳孔反射的相对速度等于1，即反射速度与扫描速度相同；（4）在无穷远处进行中和与观察距离无关。所使用的透镜可实现“纯”检影验光。
