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.
