Abstract: A lens element intended to be worn in front of an eye of a wearer including at least a first and a second set of optical elements providing respectively a first and a second optical function. When worn by a wearer, an optical element of the first set is located at a greater distance from the center of rotation of the eye than an optical element of the second set. At least some optical elements of the second set are disposed with respect to the optical elements of the first set of the lens element to provide according to a respective first and a second gaze direction on different zones of the retina of the eye of the wearer distinct cumulative optical effects.

Abstract: The invention relates to a lens element (1) intended to be worn by a wearer, comprising at least one prescription portion (2) having a first optical function configured to provide a dioptric correction of an eye of the wearer when the lens element (1) is worn by said wearer based on a prescription of the wearer, and a plurality of lenslets (3), each lenslet (3) of said plurality of lenslets being configured to provide at least one second optical function which differs from the first optical function,
wherein each lenslet (3) has a shape, a size and a position such that at least one portion of said lens element (1) has a modulation transfer function (MTF) whose values are configured so that the modulation transfer function of said lens element 1 over a range of spatial frequencies comprised between 1 and 5 cycles per degree are lower or equal to 0.6.-

Abstract: A method for characterizing optical elements of a lens element adapted for a person is presented, the lens element including: a holder including a refraction area having a refractive power based on a prescription for correcting an abnormal refraction of an eye of the person; and a plurality of optical elements configured so that at least one of slow down, retard or prevent a progress of the abnormal refraction of the eye of the person. A two-dimensional representation of the local optical power of the lens element is obtained using a fringe deflectometry method and the images used for the fringe deflectometry method consist of pixels smaller than or equal to 0.05 mm×0.05 mm.

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.
