Abstract

A CPU of an eyeglass-prescription assisting apparatus is configured to obtain measurement data on an examinee's eye measured by a wavefront sensor, including first distribution data on a refractive error distribution of an examinee's eye and second distribution data on a refractive power distribution in an eyeglass lens to correct the refractive error of the examinee's eye. The CPU further makes arithmetic processing to obtain third distribution data on a refractive error distribution taking correction with the eyeglass lens into consideration based on the first distribution data and the second distribution data.

Claims10

Dependent claims

A method for generating eyeglass-prescription assisting information, comprising:

an acquisition step of causing a computer to obtain measurement data on an examinee's eye measured by a wavefront sensor, the measurement data including first distribution data on a distribution of refractive error of the examinee's eye and second distribution data on a distribution of refractive power of an eyeglass lens to correct the refractive error of the examinee's eye;
and
an arithmetic step of causing the computer to obtain third distribution data on a distribution of the refractive error taking correction with the eyeglass lens into consideration based on the first distribution data and the second distribution data.

Dependencies are inferred from the claim text.
