1. A lens element intended to be worn in front of an eye of a wearer comprising:
at least a first and a second set of optical elements providing respectively a first and a second optical function,
wherein 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,
wherein 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 a retina of the eye of the wearer distinct cumulative optical effects,
contribution to a focus shift of transmitted light on peripheral zones of the retina of the eye of the wearer according to a first gaze direction, the first gaze direction presents a gaze angle comprised between +/−10° corresponding to far vision, and
at least partly or completely counter focus shift a focus shift induced by the first optical function of the optical elements of the first set in a central zone of the retina of the wearer according to a second gaze direction different from the first gaze direction, the second gaze direction presents a gaze angle comprised between −40° and −20° corresponding to near vision, positions of the second set of optical elements being determined with respect to the center of rotation of the eye of a wearer.
