Glasses having dynamic slight defocusing and zooming functions in emmetropia direction

Abstract

The invention discloses glasses having dynamic slight defocusing and zooming functions in an emmetropia direction and an eyesight adjusting device, and belongs to the field of eyesight rehabilitation glasses. The glasses include a carrier, a dynamic slight defocusing and zooming device having dynamic slight defocusing and zooming functions and arranged on the carrier, and an automatic focusing device for driving the dynamic slight defocusing and zooming device to defocus and zoom; the dynamic slight defocusing and zooming device includes a zooming lens group away from eyeballs and replacement lenses close to the eyeballs. The glasses can induce the eye axis length of ametropia to gradually recover to an emmetropia eye axis state; the eyesight adjusting device makes a bionic vision training device fused with the emmetropia direction dynamic slight defocusing and zooming glasses. The glasses are suitable for eliminating pathogenesis generating myopia, hyperopia, astigmatism, anisometropia, strabismus and amblyopia, and are suitable for prevention and treatment of myopia, hyperopia, astigmatism, anisometropia, strabismus, amblyopia and visual fatigue.

Description

technical field [0001] The invention belongs to the field of vision rehabilitation glasses, and in particular relates to glasses and a vision adjustment device with a dynamic mild defocusing and zooming function in the direction of the emmetropic eye. The glasses can induce the axial length of the non-emmetropic eye to gradually return to the axial state of the emmetropic eye , the vision adjustment device combines the bionic vision training device with the dynamic mild defocus zoom glasses in the emmetropic eye direction. Background technique [0002] In recent years, the incidence of myopia has remained high, the number of people is increasing, the degree is getting deeper, and the age of myopia is getting younger and younger. According to the latest statistics, there are 350 million people with myopia in my country, and the myopia rate of the general population in the United States About one-third, in other words, there are nearly 2 billion myopia patients in the world, an...

Problems solved by technology

[0004] 1. There are problems with the theory of far-near adjustment: the world's largest clinical trial of hundreds of millions of people, that is, students are looking at the near and the blackboard at school, and they are looking at the far, and the distance is adjusted for several hours a day, but myopia is still high. Insufficient blood supply to the eye is prone to visual fatigue and ciliary muscle spasm, making all distance adjustments invalid

[0005] 2. Ignoring the angle of view: Except for the eye chart, the angle of view is almost never mentioned in the chain of prevention and treatment of eye diseases such as myopia

[0006] 3. Insufficiency of three-link visual system: the visual system should be five-linked, but the theoretical basis of the existing binocular imager for the treatment of myopia is all three-linked. Does not support linkage and adjustment when judging

[0007] 4. Amblyopia treatment lacks an overall concept: in the process of amblyopia treatment, only the activation of visual cells is paid attention to, and no consideration is given to how the activated visual cells and optic nerve cells continue to work, no longer inhibited, and no longer useless. The activated visual cells are due to Without adequate blood supply, had to go into suppression again

[0008] 5. No corresponding intervention for form deprivation: because only the fovea of ​​the retina can get sufficient visual stimulation when reading at close distances, while most of the others lack sufficient stimulation so that the activity decreases, but modern medicine has not responded to this intervene

[0009] 6. Improper use of existing glasses: Myopia glasses can make distant objects farther away from the focal image plane and return to the retina for imaging

But the disadvantage is that in order to improve the eyesight smoothly, it is necessary to wear low-degree glasses and equipment to do the auxiliary training of emmetropia and defocus by walking near and far.
