Paper Abstract

There are several techniques to measure the precise structure parameters of human eye in vivo. The design methods and match of ophthalmic lens should be developed to accompany with the rapidly growing vision demands. We present a method to design custom aspherical RGP CL(rigid gas permeable contact lens) which corrects high-order aberration of RGP lens and human eye. We did the design by optimizing the aberration of the model consisting of Liou’s model eye and RGP CL, the aspherical surface was placed on the front surface and damped least-squares methods were used for the optimization. The lens designed could be manufactured in normal conditions and the wavefront aberration was reduced to get much better vision experience. It might be one important way of custom design and match of RGP CL.
