METHOD FOR CALCULATING AND OPTIMIZING AN EYEGLASS LENS TAKING INTO CONSIDERATION HIGHER-ORDER IMAGING ERRORS

摘要

The invention relates in particular to a computer-implemented method for calculating or optimizing an eyeglass lens, having the following steps: specifying at least one surface for the eyeglass lens to be calculated or optimized; ascertaining the path of a main beam (10) through at least one visual point (/) of the at least one surface; ascertaining a first primary set (si0) and a second primary set (eiok) of coefficients of the local aberration of a local wavefront (18), which extends outwards from the at least one visual point (i), in an area surrounding the main beam (10), wherein the first primary set of coefficients (sio) determines the spherical and astigmatic aberration of the outwardly extending local wavefront and the second primary set of coefficients (eiok) determines an additional aberration of a higher order (k > 2) of the outwardly extending local wavefront; specifying at least one function epk = f(eok) which assigns a second secondary set of coefficients (epk) to a second primary set of coefficients (eok), said second secondary set of coefficients determining the higher-order aberration of a propagated wavefront; ascertaining a higher-order aberration of a local wavefront that is propagated along the main beam (10) starting from the at least one visual point (/) dependent on at least the second primary set of coefficients (eiok) using the specified function epk = f(eok); and calculating or optimizing the at least one surface of the eyeglass lens taking into consideration the ascertained higher-order aberration of the propagated local wavefront.
