Abstract
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.

A lens element intended to be worn in front of an eye of a person comprising:
- a refraction area having a refractive power based on a prescription for said eye of the person;
- and
- a plurality of 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 as moving towards an edge of the lens, and
- wherein for every circular zone having a radius comprised between 4 and 8 mm comprising a geometrical center of the lens element, a ratio between the sum of areas of the parts of optical elements located inside said circular zone and the area of said circular zone is comprised between 20% and 70%.
