Manufacturing method of myopia prevention and control lens and myopia prevention and control lens

The invention relates to a manufacturing method of a myopia prevention and control lens and the myopia prevention and control lens. The manufacturing method comprises the following steps: S1, pretreating a first curved surface, facing eyes, of a lens body; s2, coating the first curved surface with a photoresist layer; s3, covering the photoresist layer with a photomask, and carrying out exposure treatment on the photoresist layer through light rays; and S4, eluting the photoresist layer through a developing solution to form a light diffusion region. The myopia prevention and control lens comprises a lens body, and the lens body is provided with a first curved surface facing the eyes and a second curved surface back to the eyes. The first curved surface is provided with a bright vision area and a light diffusion area surrounding the bright vision area, and has the beneficial effects that while vision is effectively corrected through the bright vision area, different levels of contrast reduction is accurately r
