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, onl

Embodiment 1

[0113] like Figure 1-3 , shown in 15-18, the mild defocus zoom glasses of the emmetropic eye direction dynamic rotation type in embodiment 1 include a carrier 1, a dynamic defocus zoom device with a dynamic mild defocus zoom function arranged on the carrier 1, An automatic focus device that drives a dynamic mild defocus zoom device to defocus zoom.

[0114] The center above the carrier 1 is provided with an interpupillary distance cam 8, a sound prompt device and a video recording device, and the interpupillary distance cam 8 is used to adjust the distance between the two lens barrels on the carrier according to the user's interpupillary distance; the sound prompt device It is used for reminders of different training stages and the end of training; the video device is used to record the wonderful moments seen during eye training, or to record the wonderful courses taught by the teacher, so as to facilitate future review and reduce the burden of supplementary lessons.

Embodiment 2

[0128] like Figure 4-5 , shown in 15-18: the structure of embodiment 2 is basically similar to embodiment 1, the difference is: embodiment 1 rotary zoom, embodiment 2 cantilever type zoom, because there is no limitation of the lens barrel, the field of view of embodiment 2 is very Wide, close to the normal human field of vision.

[0129] The cantilever zoom is composed of an end lens 10 fixed on the end surface of the lens holder 9 and a moving lens 11 that moves back and forth along the cantilever track 13, and the automatic focusing device is driven by the shifting block 7-2 on the screw stepping motor 7 to move The lens 11 moves back and forth along the cantilever rail 13 to complete fine defocus zooming;

[0130] There are three circular holes 11-1 (the upper two and the lower one) matching with the cantilever track 13 and the front and rear two squares matching with the stepping motor screw upper shifting block 7-2. Shift fork 11-2, stepping motor 7 is set on the canti...

Embodiment 3

[0135] like Figure 6-9, 15-18, the glasses of embodiment 3 with lateral dynamic slight defocus zoom function in the direction of the emmetropic eye include a carrier 1, a dynamic mild defocus lens with lateral dynamic slight defocus zoom function arranged on the carrier 1 A zoom device, an automatic focus device that drives a dynamic slight defocus zoom device to defocus and zoom.

[0136] Wherein, the dynamic mild defocusing zoom device is a two-lens horizontally moving zoom glasses, including a frame and two windows 16 arranged in the frame, and each window 16 is equipped with a lens for rehabilitation of non-emmetropic eyes system, the lens system includes at least one pair of lenses, constituted by a first moving lens 17 and a second moving lens 18, and the first moving lens 17 and the second moving lens 18 are arranged one behind the other when observing on the path of vision. Back, and connect with two tooth racks 20 respectively by the first moving lens connecting pie...

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...
