摘要
The aberrations for anterior corneal surface, posterior corneal surface and complete eyes are measured and calculated. The aberrations for the crystalline lens are obtained by subtracting the aberrations in cornea from that in complete eyes. It is shown that the combination between the crystalline lens and the cornea can be either a compensatory or an additive process. The combination between the anterior and the posterior corneal surfaces on the aberrations is complicated, compensatory or additive. The anterior corneal surface contributes mainly lower-order aberrations （astigmatism） of images, while the posterior corneal surface and the crystalline lens contribute mainly higher-order aberrations.
