Out-of-focus lens based on continuous curved surface and die for processing out-of-focus lens

The utility model relates to the field of lenses, and particularly discloses an out-of-focus lens based on a continuous curved surface and a mold for processing the out-of-focus lens. The out-of-focus lens based on the continuous curved surface comprises a lens body; the central light viewing area diffuses outwards along the center of the lens body and is arranged on the lens body; and the peripheral defocusing area is arranged on the lens body along the peripheral surface of the central light viewing area. According to the invention, all abrupt change parts are concentrated to the junction of the two spherical surfaces by setting the central light viewing area and the peripheral defocus area. From the normal wearing effect of the double-light mirror, as long as it is guaranteed that the transition area at the junction is small enough and the maximum cylindricity does not exceed 3.00 D, the visual sense cannot be obviously influenced, and according to the technical scheme of the invention, the central light v
