本文研究了正常青年人（n = 59）108只眼的单色像差。利用近红外夏克-哈特曼波前传感器在自然条件下测量了波前像差。对于这个人口和一个5毫米的瞳孔，超过99%的均方根波前误差包含在前四个订单的泽尔尼克展开和约91%只对应于第二个订单。35例受试者的右眼和左眼波前像差的比较显示，大部分的二阶和三阶项之间具有良好的相关性，并且眼睛之间存在轻微的（但不清楚）镜像对称趋势。(C)2002爱思唯尔科技有限公司。保留所有权利。
Monochromatic ocular aberrations in 108 eyes of a normal young population (n = 59) were studied. The wave-front aberration were obtained under natural conditions using a near-infrared Shack-Hartmann wave-front sensor. For this population and a 5 mm pupil, more than 99% of the root-mean square wave-front error is contained in the first four orders of a Zernike expansion and about 91% corresponds only to the second order. Comparison of wave-fronts aberrations from right and left eye in 35 subjects, showed a good correlation between most of the second- and third-order terms and a slight (but not clear) tendency for mirror symmetry between eyes.
