An optical zone forms a base surface of a spectacle lens and has a refractive power per a prescription. A functional zone surrounds a central optical zone of the spectacle lens and includes a plurality of functional sub-elements fitting with one another. Each of the functional sub-elements includes a first lens located in a central position and a plurality of second lenses around the first lens. Each of the second lenses has a surface shape of a regular polygon. The second lenses are in surface contact with one another via a surface where sides of the regular polygons are located. Wavefronts formed by the functional sub-elements can be superimposed on a working focal plane of the optical zone to form a uniform difussion circle that can form a blurred peripheral vision image. The spectacle lens can perform deep modulation for the imaging quality of the image plane on the retina.
