Zusammenfassung:The utility model relates to the technical field of lens preparation, in particular to a multi-point out-of-focus lens. Comprising a lens concave surface and a mirror surface convex surface, the mirror surface convex surface is provided with an outer ring refraction area, a middle ring refraction area and an inner ring refraction area, and the outer ring refraction area, the middle ring refraction area and the inner ring refraction area are gradually arranged from the outer ring of the mirror surface convex surface to the midpoint; a micro-lens group consisting of a plurality of micro-lenses is also arranged on the convex surface of the mirror surface, the micro-lens group is annularly arranged along the midpoint of the convex surface of the mirror surface, and the outer diameters of the micro-lenses on the first inner ring of the micro-lens group are in contact with one another; and starting from the second ring, the micro-lenses on the micro-lens group are arranged on the extension lines of the micro-lenses
