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 a spectacle lens, comprising the steps of: specifying at least one surface for the spectacle lens to be calculated or optimized; determining the course of a main ray (10) through at least one visual point (i) of the at least one surface; determining a first primary set (sio) and a second primary set (eiok) of coefficients of the local aberration of a local wavefront (18) going out from the at least one visual point (i) in a surrounding of the main ray (10), wherein the first primary set of coefficients (sio) defines the spherical and astigmatic aberration of the outgoing local wavefront and the second primary set of coefficients (eiok) defines at least one further higher-order aberration (k>2) of the outgoing local wavefront; specifying at least one function epk=ƒ(eok) which assigns a second secondary set of coefficients (epk) to a second primary set of coefficients (eok), said second secondary set of coefficients defining the higher-order aberration of a propagated wavefront; determining a higher-order aberration of a local wavefront propagated starting from the at least one visual point (i) along the main ray depending on at least the second primary set of coefficients (eiok) on the basis of the specified function epk=ƒ(eok); and calculating or optimizing the at least one surface of the spectacle lens taking into consideration the determined higher-order aberration of the propagated local wavefront.
