Abstract

The invention relates to a spectacle lens with different front-view refraction cluster groups in different view fields and a manufacturing method of the spectacle lens, in the aspect of the spectacle lens, on the basis of introducing a concept of continuously increasing different lower addition light and a free-form surface concept in the different view fields, through the design of different diopters in the different front-view refraction cluster groups, the different front-view refraction cluster groups have different diopters; the diopter switching of the multi-stage micro-lens glasses with 3, 5, 7 and 9 which can be perceived by human eyes in the same field of view becomes possible, so that far and near object images can clearly fall on the retina, and the eyes are not tired when the glasses are used. In the aspect of manufacturing methods, a 3D printing additive manufacturing method and a substrate machining subtractive manufacturing method which are commonly used for a free-form surface are selected; an injection molding technology and a micro-nano imprinting technology are creatively fused, and an injection molding hot-pressing micro-nano imprinting manufacturing method and a substrate photosensitive micro-nano imprinting manufacturing method are provided; the injection molding hot-pressing micro-nano imprinting method and the substrate photosensitive micro-nano imprinting method can be used for batch production of glasses matching persons suitable for selecting free-form surface big data, so that high-quality glasses which are the same as customized glasses can be obtained.

Description

technical field [0001] The spectacle lens of the present invention relates to a micron-level emmetropia refractive cluster, in particular to an spectacle lens with different emmetropia cluster groups in different fields of view and a manufacturing method thereof. Background technique [0002] The myopia of young people is becoming more and more serious, and the situation is very serious. It has become a social and people's livelihood problem, which seriously affects personal life, family harmony and national security. [0003] Modern ophthalmology believes: "True myopia, the eye axis has been elongated, it is impossible to shorten it like a long person, and myopia cannot be treated", "high hyperopia, the eye axis has not developed in place at the beginning, and now the time for development has passed. It is impossible to make up the length of the eye axis, and farsightedness cannot be treated”, “Astigmatism is a congenital need to wear glasses for a lifetime, and astigmatism...
