Zusammenfassung: | The present invention relates to an adjusted hysteresis multi-zone peripheral defocus optical element and lens comprising: a first refractive region providing a first diopter as a base diopter and covering a central region of the optical element in a circular manner; the third refraction area, the fourth refraction area, the fifth refraction area and the sixth refraction area are arranged on the periphery of the first refraction area in the mode of forming a concentric ring surrounding the first refraction area, the occupied radian ranges are roughly the same, and the third refraction area, the fourth refraction area, the fifth refraction area and the sixth refraction area can be further divided into three concentric sector rings of the inner side, the middle and the outer side. Diopters different from the basic diopters are provided respectively; the second refraction area is a concentric sector ring area arranged at the intersection position of the concentric sector rings on the inner sides of the first ref |
