The spatially resolved wavefront aberrations of four types of ophthalmic lens are measured with a custom-built apparatus based on a Hartmann-Shack wavefront sensor and specially designed positioning stage. The wavefront aberrations of the progressive addition lenses (PALs) are compared. The results show that the distribution depends much on the design philosophy, although the average values of root mean square in the entire measurement areas have no significant difference. It is feasible to evaluate the optical performance through the wavefront analysis of PALs, but how to meet the customized visual needs of patients and how to minimize the unwanted aberrations in some special zones are important points that should be taken into account.
使用基于哈特曼-夏克波前传感器和专门设计的定位平台的定制设备，测量了四种类型眼科镜片的空间分辨波前像差。对渐进多焦点镜片（PAL）的波前像差进行了比较。结果表明，尽管整个测量区域内均方根的平均值没有显著差异，但分布情况很大程度上取决于设计理念。通过对PAL进行波前分析来评估光学性能是可行的，但是如何满足患者的个性化视觉需求以及如何最小化某些特殊区域中不必要的像差是需要考虑的重要问题。
