Grid type out-of-focus glasses lens capable of inhibiting growth of eye axis and therapeutic apparatus

Abstract

The invention provides a grid type out-of-focus glasses lens capable of inhibiting the growth of eye axis and a therapeutic apparatus and belongs to the technical field of optical lenses for eye health care and treatment. A plurality of visual areas are distributed in the glasses lens and each visual area is provided with a lens for correcting myopic refraction and comprises a hyperopia or myopiacorrection lens, a plain lens or hole, and a first astigmatism correction lens; one visual area is a main visual area So and the residual visual areas are secondary visual areas Si; a part out of thevisual areas is an out-of-focus area Sx and the out-of-focus area Sx has a connected grid form; the out-of-focus area Sx contains a positive lens and a second astigmatism correction lens which is thesame as or basically the same as the first astigmatism correction lens; the diopter B2 of the positive lens is greater than 0DS; or the out-of-focus area Sx contains an out-of-focus lens. According tothe grid type out-of-focus glasses lens provided by the invention, horizontal expansion of eyeballs is controlled and the growth of the eye axis is inhibited; when the growth of the eye axis is inhibited, a relatively great full-clear eyesight range can be provided; and the grid type out-of-focus glasses lens is comfortable to use, has no interference and does not easily cause eye fatigue.

Description

technical field [0001] The invention belongs to the technical field of optical lenses used for eye care and treatment, and more specifically relates to a grid-type defocused spectacle lens that suppresses eye axis growth. Background technique [0002] The essence of the development of myopia is caused by the increase of eye axis, and inhibiting the increase of eye axis can prevent the development of myopia. In the prior art, the myopic defocusing of the peripheral retina can inhibit the increase of the eye axis, which can inhibit the development of myopia to a certain extent, but the defocusing of the peripheral retina will affect the clear field of vision, making it inconvenient to see the surrounding area clearly. It also leads to potential safety hazards for people's actions under special circumstances; at the same time, it is easy to cause visual fatigue, which affects the effect of myopia treatment. That is to say, in the prior art, there is a problem that while contro...

Problems solved by technology

[0003] The object of the present invention is to provide a grid-type defocused spectacle lens and a therapeutic device that suppresses the growth of the eye axis, mainly to solve the problems in the prior art that the range of clear vision is small, it is inconvenient to see the surrounding things clearly, and it leads to potential safety hazards and easy Problems that cause visual fatigue and affect the effect of myopia treatment
