Abstract: A lens that spreads light from a point light source includes a light entry side having a first Fresnel structure, a light exit side having a second Fresnel structure different from the first Fresnel structure, a section plane located entirely between the first and second Fresnel structures so that the lens is flat, and a central axis as an optical axis perpendicular to the section plane, wherein a height of Fresnel rings of the first Fresnel structure, referred to the section plane, increases in the direction away from the central axis, the Fresnel rings of the first Fresnel structure each have an entry surface facing towards the central axis and a deflecting surface facing away from the central axis, and Fresnel rings of the second Fresnel structure each have a mirror surface facing towards the central axis and an exit surface facing away from the central axis.
