METHOD FOR OPTIMIZING A SPECTACLE LENS FOR THE WAVEFRONT ABERRATIONS OF AN EYE AND LENS

摘要

The current invention is directed to a method (36) for designing an ophthalmic lens element (24), the method (36) comprising the steps of determining (38) a wavefront aberration of an eye (26) in a reference plane (28), wherein the wavefront aberration of the eye (26) can be described by a first series of polynomials of ascending order up to a first specific order and corresponding first coefficients; and determining (40; 42) a first vision correction of a second specific order to obtain an adapted ophthalmic lens element (24); determining (44) at least one specified point (50) over an aperture (48) of the adapted ophthalmic lens element (24); determining (52) a high-order wavefront aberration in the reference plane (28) for each specified point (50) of the adapted ophthalmic lens element (24), wherein the high-order wavefront aberration can be described by a third series of polynomials of ascending order above the second specific order up to and including the first specific order and corresponding third coefficients; determining (54; 56; 58) a second vision correction of the second specific order for each of the specified points to obtain an optimized ophthalmic lens element (24) based on the first vision correction (40) up to and including the second specific order and based on combined first and third coefficients above the second specific order and up to and including the first specific order. Further, the current invention is directed to a method for manufacturing an ophthalmic lens element, a computer program product and a system for carrying out the methods.
