Curve gradual change type multi-point out-of-focus lens

The utility model relates to a curve gradual change type multi-point out-of-focus lens, and belongs to the technical field of myopia prevention and control lenses. According to the curve gradual change type multi-point defocusing lens provided by the utility model, the corresponding curve gradual change defocusing amount design instead of the one-step linear fixed defocusing amount design is performed from the innermost ring of the defocusing intervention area of the first micro convex lens array to the outside according to the myopia degree of a myopia patient and the change of mild, moderate and severe myopia; in other words, the defocusing amounts of the positions of the second circle, the third circle and the fourth circle of the defocusing intervention area of the micro convex lens array are large, and then the defocusing amounts to the edges of the lenses are gradually reduced, so that the large defocusing amount is implemented at the position of the 15-degree field angle of the lens eye distance, and t
