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.
