Abstract: Disclosed in the present disclosure is an eyeglass lens for preventing and controlling myopia. The eyeglass lens includes a lens body, the lens body includes a first area, a second area, and third areas, the first area is a regular area formed with an optical centre of the lens body as a centre, the first area has a refractive power with a myopia correction function, the second area is a peripheral area of the lens body, and the second area is used for focusing an image on a position in front of a retina of an eye, to inhibit myopia development of the eye. The present disclosure has a simple structure and rational design, when a patient views an object with the eyeglass lens for preventing and controlling myopia, an image is formed on the retina, meanwhile, an image is formed in front of the retina, and a contrast of imaging at the periphery of the retina is reduced, such that the eyeglass lens has a function of inhibiting or at least slowing down development of myopia of a human eye, and a machining cost can be effectively controlled, to facilitate promotion and popularization of vision protective lenses.
