Zusammenfassung: | The invention relates to a lens element intended to be worn in front of an eye of a wearer, the lens element being adapted to provide a prescribed dioptric correction function in a prescription plane, the lens element comprising an arrangement of microoptical elements, wherein, when receiving a collimated beam of monochromatic light: - the lens element is configured to produce a primary luminous intensity maximum in a prescription plane, - the arrangement of microoptical elements is configured to produce at least one first secondary luminous intensity maximum at a first proximity difference from the prescription plane and at least one second secondary luminous intensity maximum at a second proximity difference from the prescription plane, the first proximity difference and the second proximity difference having opposite signs. |
