Vision control lens based on peripheral micro-lens, and glasses

Abstract

The invention relates to a vision control lens based on a peripheral micro-lens. The vision control lens comprises a lens body; the lens body sequentially comprises a central fixed light area and a peripheral light area from inside to outside. An out-of-focus micro-lens is arranged on the peripheral light area, so that an optical focal point of the peripheral light area falls on a retina or in front of the retina, and the increase of the myopia degree is effectively relieved.

Description

technical field [0001] The invention relates to the technical field of myopia lenses, in particular to vision control lenses and glasses based on peripheral microlenses. Background technique [0002] Myopia is when images of distant objects are focused in front of the retina, resulting in blurred distance vision. The existing simple and effective way is to wear concave lenses, that is, myopia glasses, to diverge the light and focus it on the retina. [0003] However, for children, their eyeballs are in the developing stage. If children gradually develop myopia due to bad reading habits, the optical focus of the peripheral part of the myopia lens falls behind the retina, such as figure 1 As shown, the eye axis will be forced to lengthen to receive this part of visual information, which will easily form a vicious circle on the physiology of the eyeball, causing the eye axis to be further stretched, resulting in more serious vision loss. At present, there are existing myopia ...

[0003] However, for children, their eyeballs are in the developing stage. If children gradually develop myopia due to bad reading habits, the optical focus of the peripheral part of the myopia lens falls behind the retina, such as figure 1 As shown, the eye axis will be forced to lengthen to receive this part of visual information, which will easily form a vicious circle on the physiology of the eyeball, causing the eye axis to be further stretched, resulting in more serious vision loss

At present, there are ordinary spherical, aspheric and other myopia glasses on the market, none of which have the function of preventing the progression of myopia
