Abstract
By the technique of dynamic retinoscopy, we found that the alert newborn infant can focus his eye on targets only at a particular distance (median, 19 centimeters). Images of targets nearer or farther away are proportionately blurred. However, during the first few postnatal months the range of flexible accommodation increases and approximates adult performance by the 4th month.
摘要
通过动态检影技术，我们发现警觉的新生儿仅能将眼睛聚焦于特定距离（中位数为19厘米）的目标上。距离更近或更远的目标图像会相应地模糊。然而，在出生后的头几个月里，灵活调节的范围会增加，并在第4个月时接近成人水平。
