Abstract

The invention relates to a method for determining an ophthalmic lens for a wearer and suitable for correcting the wearer's vision, comprising c) determining a virtual lens by an optimization process involving calculating iteratively a surface of the virtual lens so as to match target optical characteristics of a target lens, checking whether peripheral defocus values of the virtual lens satisfy a predetermined criterion, and if the predetermined criterion is not satisfied, reiterating the calculation of the surface of the virtual lens after modifying the target lens of the previous iteration. The determined ophthalmic lens is defined as being the virtual lens at the end of the optimization process. The invention also relates to an ophthalmic lens for a wearer for correcting the wearer's vision and intended to reduce peripheral defocus.
