Visual system bionic training instrument having function of adjustable emmetropia out-of-focus glasses

Abstract

The invention relates to a visual system bionic training instrument having the function of adjustable emmetropia out-of-focus glasses. The visual system bionic training instrument is characterized in that the two technologies of bionic visual training and emmetropia direction out-of-focus training are integrated. By means of seven kinds of visual system bionic training provided by a researcher in a previous patent application, storage of seven kinds of visual system strength is increased, the three necessary conditions for well maintaining the eyes are recovered, and thus the sight of a user is stably recovered and improved. Meanwhile, the emmetropia out-of-focus glasses are adjusted to the light emmetropia out-of-focus state in working, studying and entertaining, the auxiliary training of walking front and back in the past is replaced, and the eyeball emmetropia is induced more standardly. The glasses have the functions that by replacing and selecting the degrees of lenses (ocular lenses 1), the adjustable glasses can be suitable for all ametropia crowds, and the process of gradual recovery of non-emmetropia to emmetropia is accelerated through the emmetropia direction light out-of-focus state formed by fining degree adjustment of the distance of the two lenses.

Description

technical field [0001] The invention relates to a visual system bionic training instrument with the function of adjustable emmetropic defocus glasses, in particular to a treatment device for myopia, hyperopia, astigmatism, amblyopia, strabismus and anisometropia which combines bionic vision training with adjustable defocus glasses. Background technique [0002] In recent years, the incidence rate of myopia remains high. According to the fourth national student constitution survey in 2000, the myopia rate of students in my country is 20.23% for primary school students, 48.18% for junior high school students, 71.29% for high school students, and 73.01% for college students. A survey in Hong Kong shows that the myopia rate of elementary school students is very common, and the myopia rate of primary school students in the sixth grade is as high as 60%, which is twice as high as that in New York; it is estimated that the myopia rate of middle school students is as high as 75%.

Problems solved by technology

[0012] 3. There is a loophole in the visual triple linkage:

[0013] There is a loophole in the theoretical basis of the existing binocular imager for the treatment of myopia. The visual system should be five-linked.

The three linkages only have set changes but no perspective changes. When comparing judgments with empirical data, the brain will be confused or have a feeling of "being fooled" because there is no perspective change. Therefore, it does not support linkage and does not support adjustment (like a fool camera when it lacks important detection information. unable to complete the adjustment

[0014] 4. There is no overall concept of amblyopia treatment:

[0015] During the treatment of amblyopia, we only pay attention to the activation of visual cells, and do not consider how the activated visual cells and optic nerve cells can continue to work, no longer inhibited and no longer useless. (The weak point is: the activated visual cells do not have sufficient blood supply, had to go into suppression again)

In addition, during the activation of the visual cells, a large viewing angle error was made (the viewing angle of the commercially available myopia and amblyopia treatment device is at least 150 minutes), so that it is necessary to use "pinholes", "beads" and so on. Family fine vision training and "grating therapy" and "afterimage therapy" to remedy (missing: super fine vision training with small viewing angle)

As a result, the course of treatment is as long as 2 to 3 years, or even 7 to 8 years, and the curative effect is not good.

[0016] 5. Only form perception deprivation without corresponding intervention:

[0018] 6. Existing glasses and their usage methods are important reasons why true myopia cannot be cured:

The disadvantage is that in order to improve vision smoothly, it is necessary to wear low-degree glasses and cooperate with the equipment to do auxiliary training of emmetropia (direction) and defocus (foggy vision therapy) for walking near and far. The curative effect is not constant

[0028] The disadvantage of this patent is that ① only two lenses are adjusted, and the applicable surface is narrow (0-400 degrees), which is not suitable for patients with high myopia, hyperopia, and amblyopia; ② patients with high myopia (such as 900 degrees) watch TV for treatment The distance between the TV and the TV is less than 30cm. Although the instrument itself has anti-radiation function, the impact of radiation on the body at such a close distance cannot be ignored; The mechanism of the regulating device described in the patent is also wrong

The action site of this patent is not the contraction state of the ciliary muscle, and the dominant action mechanism is not the regulation theory
