Abstract

The current invention is directed to a method for designing an ophthalmic lens element, the method comprising the steps of determining a wavefront aberration of an eye in a reference plane, wherein the wavefront aberration of the eye can be described by a first series of polynomials of ascending order up to a first specific order and corresponding first coefficients; determining a first vision correction of a second specific order; determining at least one specific point over an aperture of the adapted ophthalmic lens element; determining a high-order wavefront aberration in the reference plane for each specified point of the adapted ophthalmic lens element, 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; and determining a second vision correction of the second specific order.
