A lens element worn in front of an eye of a person includes a refraction area having a refractive power based on a prescription for the eye of the person, and a plurality of at least three optical elements, wherein the optical elements are configured so that along at least one section of the lens the mean sphere of optical elements increases from a point of the section towards the peripheral part of the section.

Lens element

A method is provided for determining an ophthalmic lens configured to correct an abnormal refraction of an eye of a wearer and including at least three optical elements disposed on a surface of the ophthalmic lens to suppress or reduce a progression of the abnormal refraction of the eye, the method including providing prescription data configured to correct the abnormal refraction; providing at least one abnormal refraction parameter relating to the abnormal refraction; providing at least one sensitivity parameter representing a variation of sensitivity of the wearer as a function of at least one parameter of the optical elements; determining a value of the at least one parameter of the optical elements configured for the wearer based on the abnormal refraction parameter and the sensitivity parameter; and determining the ophthalmic lens based at least on the provided prescription data and the value of the parameter of the optical elements.

The present disclosure includes optical articles comprising a film layer that has first and second film surfaces and is embossed such that the first film surface defines a plurality of concave optical elements and the second film surface defines a plurality of convex optical elements. The present optical articles can include one or more optical layers coupled to the film layer. Each of the optical layer(s) can encapsulate the concave optical elements or the convex optical elements.

The present disclosure includes optical articles comprising a lens having first and second lens surfaces and a protective layer having first and second protective surfaces that is coupled to the lens such that the first protective surface is disposed on the second lens surface. The optical article can comprise a plurality of convex or concave optical elements defined on the second lens surface or the first protective surface. The protective layer can have a maximum thickness larger than a maximum height of each of the optical elements such that the protective layer encapsulates the optical elements.

A method to select or to conceive/design lenses is provided. The method may be applied to lenses having effect of myopia control, visual fatigue relief, etc. In one aspect, a predictive model that ranks myopia control solutions according to visual, behavioral, and biometric parameter is provided. The predictive model may be built based on the myopic eye characteristics, the behavior of the wearers, and the defocus induced by the myopia control solution. In another aspect, a method, a computer-readable medium, and an apparatus for evaluating the efficacy of an ophthalmic lens in controlling at least one sightedness impairment (e.g., myopia) of at least one wearer of the ophthalmic lens are provided. The apparatus may determine, based on a predetermined relationship model, the efficacy of the ophthalmic lens for at least one wearer from representative data corresponding to the at least one wearer.

A lens element intended to be worn in front of an eye of a person including a refraction area having a first refractive power based on a prescription for correcting an abnormal refraction of said eye of the person and a second refractive power different from the first refractive power, and a plurality of at least three optical elements, at least one optical element having an optical function of not focusing an image on the retina of the eye so as to slow down the progression of the abnormal refraction of the eye.

A lens element intended to be worn in front of an eye of a person that includes a refraction area having a refractive power based on a prescription for the eye of the person, and a plurality of at least three non-contiguous optical elements, at least one optical element having a non-spherical optical function.

An optical article may include a frame, a first active lens arrangement coupled to the frame, and a second active lens arrangement coupled to the frame. The first active lens arrangement and the second active lens arrangement may be lined up abreast with respect to each other. Further, the optical article may include a time-based optical power adjustment mechanism coupled to the first active lens arrangement and the second active lens arrangement. The time-based optical power adjustment mechanism may be configured to vary the optical power of the first active lens arrangement and the second active lens arrangement in accordance with a predetermined adjustment.
