and at least three non-contiguous optical elements, at least one optical element of the at least three non-contiguous optical elements having a non-spherical optical function, wherein the at least three optical elements are configured so that along at least one section of the lens element, a mean sphere of the at least three optical elements increases from a first point of the at least one section towards a peripheral part of the at least one section by at least 0.5 D, and decreases from a second point of the at least one section towards the peripheral part of the at least one section by at least 0.5 D, the second point being closer to the peripheral part of the at least one section than the first point, wherein at least one optical element of the at least three non-contiguous optical elements is a multifocal refractive micro-lens, and wherein the multifocal refractive micro-lens includes an aspherical progressive surface. ### Claim 2 (depends on 1) The lens element according to claim 1, wherein at least one optical element of the at least three non-contiguous optical elements includes a toric surface. ### Claim 3 (depends on 1) The lens element according to claim 1, wherein at least one optical element of the at least three non-contiguous optical elements is a toric refractive micro-lens. ### Claim 4 (depends on 1) The lens element according to claim 1, wherein at least one optical element of the at least three non-contiguous optical elements is made of a birefringent material. ### Claim 5 (depends on 1) The lens element according to claim 1, wherein at least one optical element of the at least three non-contiguous optical elements is a diffractive lens. ### Claim 6 (depends on 5) The lens element according to claim 5, wherein the diffractive lens includes a metasurface structure. ### Claim 7 (depends on 5) The lens element according to claim 5, wherein at least one optical element of the at least three non-contiguous optical elements is a multifocal binary component. ### Claim 8 (depends on 1) The lens element according to claim 1, wherein at least one of the at least three non-contiguous optical elements is located on a front surface of the lens element. ### Claim 9 (depends on 1) The lens element according to claim 1, wherein at least one of the at least three non-contiguous optical elements is located on a back surface of the lens element. ### Claim 10 (depends on 1) The lens element according to claim 1, wherein at least one of the at least three non-contiguous optical elements is located between a front and a back surfaces of the lens element. ### Claim 11 (depends on 1) The lens element according to claim 1, further comprising: an ophthalmic lens bearing the refraction area and a clip-on bearing the at least three non-contiguous optical elements adapted to be removably attached to the ophthalmic lens when the lens element is worn. ### Claim 12 (depends on 1) The lens element according to claim 1, wherein a ratio between a sum of areas of parts of optical elements located inside a circular zone and an area of said circular zone is comprised between 20% and 70% of the lens element, wherein the circular zone has a radius comprised between 2 mm and 4 mm and includes a geometrical center of the lens element. ### Claim 13 A lens element for wearing in front of an eye of a person, the lens element comprising: a refraction area having a refractive power based on a prescription corresponding to said eye of the person; and at least three non-contiguous optical elements, at least one optical element of the at least three non-contiguous optical elements having a non-spherical optical function, wherein the at least three optical elements are configured so that along at least one section of the lens element, a mean sphere of the at least three optical elements increases from a first point of the at least one section towards a peripheral part of the at least one section by at least 0.5 D, and decreases from a second point of the at least one section towards the peripheral part of the at least one section by at least 0.5 D, the second point being closer to the peripheral part of the at least one section than the first point, wherein at least one optical element of the at least three non-contiguous optical elements is a diffractive lens, and wherein the diffractive lens includes a metasurface structure.
