[0010] CN110068938A A nasotemporal peripheral defocus spectacle lens based on eye adjustment set belongs to the field of eyewear technology. Existing myopia spectacle lenses cannot simultaneously correct the asymmetric hyperopic defocus of the nasotemporal retinal periphery of the myopic eye and correct the eye adjustment set dysfunction.

This spectacle lens has the function of simultaneously correcting the asymmetric hyperopic defocus of the nasotemporal retinal periphery of the myopic eye and correcting the myopic eye adjustment and set dysfunction, and is suitable for wearing by children and adolescents with normal eye position, esotropia or exotropia.

[0011] CN209803477U A nasotemporal peripheral defocus spectacle lens based on eye adjustment set belongs to the field of eyewear technology. Existing myopic spectacle lenses cannot simultaneously correct the asymmetric hyperopic defocus of the nasotemporal retinal periphery of the myopic eye and correct the eye adjustment set dysfunction. The utility model spectacle lens surface type is set to four areas: a nasal treatment area, a temporal treatment area, a central correction area, and an adjustment set correction area. Based on the eye adjustment set, it is set to four types: progressive multifocal adjustment type and set type nasotemporal peripheral defocus spectacle lens, dual focus adjustment type and set type nasotemporal peripheral defocus spectacle lens. This spectacle lens has the function of simultaneously correcting the asymmetric hyperopic defocus of the nasotemporal retinal periphery of the myopic eye and correcting the myopic eye adjustment and set dysfunction, and is suitable for wearing by children and adolescents with normal eye position, esotropia or exotropia.

[0012] CN214474292U The utility model discloses a double-sided composite design asymmetric peripheral myopia defocus spectacle lens, comprising a lens body, wherein the lens body is composed of a front side of the lens and a back side of the lens, wherein the front side of the lens is a standard asymmetric design of fixed defocus, and the back side of the lens is an adjustable defocus compensation value design, and the total defocus of the lens body is formed by superimposing the front side of the lens and the back side of the lens. The utility model has the beneficial effects of eliminating the thickness difference between the upper edge and the lower edge of the standard asymmetric peripheral myopia defocus lens by means of a mold center positioning platform, and at the same time, since a considerable part of the defocus compensation value is shared on the front side of the lens, the required free curved surface on the back side of the lens and the difficulty of processing are reduced, so that the asymmetric peripheral myopia defocus lens with a compensation value exceeding 1.50D still maintains the overall standard asymmetric defocus design, which is beneficial to the effect of reducing the peripheral hyperopia defocus amount of adolescent myopia wearers when reading at close range for a long time, and brings better myopia prevention and control effects.

[0013] CN213659117U The utility model discloses a defocus lens for preventing and alleviating myopia, comprising a frame, a lens body is embedded in the frame, the lens body is a concave-convex lens as a whole, the lens body is provided with a central correction area, a paracentral defocus area and a peripheral defocus area from the inside to the outside, the central correction area is located at the center of the lens body, the peripheral defocus area is located at the edge of the lens body, the paracentral defocus area is located between the central correction area and the peripheral defocus area, the peripheral defocus area is asymmetrically matched with seven curvature rings of the posterior pole of the individual eye, and the curvature ring includes a ring-shaped closed curved ring diffused from the center point of the lens body. The defocus lens for preventing and alleviating myopia fundamentally solves the retinal peripheral hyperopic defocus phenomenon caused by traditional optical glasses, and provides a more comfortable, accurate and clear visual quality experience for children and adolescents with myopia.

[0014] CN215986774U The utility model discloses a double-sided composite multi-point defocusing eyeglass, comprising a lens body, which is made of the same optical material and is composed of a front surface and a rear surface. The optical area of ​​the lens body is divided into an intermediate refractive correction visual area with a refractive power gradually changing from the center to the bottom, a peripheral defocusing area with dense sub-lenses, and a peripheral refractive correction visual area. The front surface of the peripheral defocusing area is provided with a plurality of circles of sub-lenses arranged in an elliptical ring shape for defocusing, and the rear surface is a free-form surface; the refractive power of the intermediate refractive correction visual area decreases from top to bottom, and the refractive power of the peripheral defocusing area gradually decreases from top to bottom. The double-sided composite multi-point defocusing eyeglass provided by the utility model has a good effect in correcting the refractive error of the eye and can effectively inhibit the development of the refractive error of the eye.

[0015] From the above literature, it can be seen that the area of ​​the defocus lens is generally divided into multiple areas, namely the central luminosity stable area, the paracentral defocus area and the peripheral defocus area. There is no interpretation of the specific size of these areas. At the same time, the current patent does not give the relationship between the defocus amounts between areas. The defocus amount is a crucial parameter for alleviating the development of myopia in adolescents. The larger the area and intensity of the defocus amount, the stronger the ability to inhibit the development of myopia. However, too high a defocus amount will lead to a decrease in the comfort of the wearer. Summary of the invention

[0016] The object of the present invention is to provide a method for manufacturing a differentiated defocus increment resin lens with good defocus processing effect in view of the above problems.

[0052] S21: dividing a circular area with the geometric center point of the lens as the center of the first refractive zone 11, and processing the refractive power of the first refractive zone 11 to be consistent with the corrected vision refractive power of the wearer;

[0053] S22: A second refractive zone 12, a third refractive zone 13, a fourth refractive zone 14 and a fifth refractive zone 15 are divided between the first refractive zone 11 and the edge of the semi-finished blank lens. The second refractive zone 12 is an elliptical area that does not include the first refractive zone 11.
