Out-of-focus lens based on discontinuous 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 discontinuous curved surface and a mold for processing the out-of-focus lens. The out-of-focus lens based on the discontinuous curved surface comprises a base lens, the center of a lens body is provided with a central light viewing area formed by outward diffusion along the center of the base lens, and the periphery of the central light viewing area is provided with a peripheral out-of-focus 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. According to the technical scheme, it can be found from the normal wearing effect of the double-light mirror that a single linear connecting mark at the junction does not have obvious influence on vision, the central light viewing area and the peripheral defocus area are arranged in a zoning mode, the purpose that the asti
