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 a center of rotation of the eye than an optical element of the second set,
at least some of the optical elements of the first set and the second set are disposed in a mutual relationship in such a way that, for at least one gaze direction, a first and a second cumulative optical effect are provided at the same time for respective at least first and second incoming light beams;
the first optical cumulative effect is provided for said first incoming light beam impinging in peripheral zones of a retina of the wearer and comprises a contribution to a focus shift; and
the second optical cumulative effect is provided for said second incoming light beam impinging in a central zone of the retina of the wearer and includes a contribution to at least partly or completely counter focus shift a focus shift induced by the first optical function of the first set of optical elements by optical elements of the second set.
