Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that in each implementation manner of the present invention, many technical details are proposed in order to enable readers to better understand the present invention. However, even without these technical details and various changes and modifications based on the following embodiments, the technical solution claimed by each claim of the present invention can also be realized.

[0018] As mentioned in the background technology above, although wearing ordinary glasses can correct refractive errors such as myopia and obtain better central vision, but at the same time it will also lead to increased hyperopic defocus around the retina, and it will increase as the degree of myopia increases. . ref...

Abstract

The invention relates to a spectacle lens capable of effectively relieving myopia deepening. The spectacle lens comprises a lens body, wherein the whole lens body is in a concave lens; the lens body sequentially comprises a central full-straightening area and a peripheral positive defocus area from inside to outside; the peripheral positive defocus area is matched with the curvature of the rear pole part of individual eyes; on the basis of the myopia defocus theory, myopia development can be effectively relieved, and a phenomenon of hyperopia defocus of the retina caused by traditional opticalspectacles can be fundamentally corrected; the spectacle lens is realized through a micron-nano 3D printing technology, so that the precision is high, the cost is low, and more comfortable, accurateand clear visual quality experience is provided for myopia patients.

Description

technical field [0001] The invention relates to the technical field of spectacle lenses, in particular to a spectacle lens capable of effectively alleviating myopia progression, a corneal contact lens and a lens film. Background technique [0002] Myopia is when images of distant objects are focused in front of the retina, resulting in blurred distance vision. Myopia has become a national disease in my country: the total number of patients exceeds 400 million, and the prevalence rate among people over 5 years old is as high as 40%; and the age of onset of myopia is greatly advanced, which makes myopic children a huge group. Many children begin to face the problem of wearing glasses in elementary school. At present, the most commonly used method of myopia correction is still wearing glasses, that is, myopia glasses, which diverge light and focus it on the retina. [0003] However, in the prior art, the correction accuracy of ordinary myopia lens is not high, and it will lea...
