This paper demonstrates how accommodation and refractive changes affect the brightness of the reflex observed during retinoscopy. The amount of light entering the peephole of the retinoscope was monitored while accommodation was varied. The light entering the peephole reaches a maximum when the far-point of the eye is co-incident with the retinoscope and drops when the far-point moves behind or in front of the retinoscope. A reduction in the accommodative lag during book retinoscopy would result in brightening of the reflex along with a shift in the "against" direction.
本文展示了调节和屈光变化如何影响检眼镜检查时观察到的反射光亮度。在调节变化时，监测进入检眼镜窥孔的光量。当眼睛的远点与检眼镜重合时，进入窥孔的光量达到最大值，而当远点移到检眼镜后方或前方时，光量会下降。在近距检眼镜检查期间调节滞后的减少会导致反射光变亮，并伴有“逆动”方向的偏移。
