Description
The technical field is as follows:
the invention relates to a device for preventing and treating eye diseases such as myopia and the like.
Background art:
and (3) counting the morbidity: the fourth national student physique survey in 2000 shows that the myopia rate of students in China is as follows: 20.23% of pupils, 48.18% of junior middle school students, 71.29% of senior high school students and 73.01% of college students. Hong Kong surveys show that the myopia rate of primary school students is very common, the myopia rate of six grade students in primary school is as high as 60% which is twice as high as New York, and the myopia rate of middle school students is estimated to be more than 75%. Taiwan students also have high myopia rates, with primary school students 12% in grade one, 55% in grade six, middle school students 76% in grade three, and high school students 85% in grade three. Foreign situations are also not optimistic: for example, the vision defect rate of the students in the third grade of high school in Japan is 57%, the myopia rate of the graduates in the high school of Singapore Chinese is 78%, the myopia rate of the general population in the United states is one third, and the myopia rate in European regions is less, but a large number of myopia groups exist. The investigation shows three worried points, namely more and more myopia people, deeper and deeper myopia degrees and younger myopia people, which bring great inconvenience to the study and life of students.
In order to meet the market demand, the eyesight protection instruments, the eyesight protection devices, the eyesight correction instruments, the physical therapy instruments, the vision increasing instruments and the like which are produced at the same time are in endless numbers, and the defects are that,
the prior art considers that: the binocular imaging technology simulates a far target by a near target, so that the eyes can obtain the coordinated exercise of seeing far and seeing near in the surrounding of a near environment, and ciliary muscles are fully relaxed, thereby achieving the effects of treating pseudomyopia and preventing relapse. "
Binocular fusion is "based on human visual physiology: when people see a nearness, the visual axes of the two eyes must be integrated inwards, so that the adjustment and the enhancement are realized, and the pupils are shrunk; when looking far away, the visual axes of the eyes are scattered, the adjustment is relaxed, and the pupil recovers the original size or is enlarged.
Namely, all binocular imaging therapeutic apparatuses only consider the matching operation of intraocular muscles, extraocular muscles and crystalline lenses, do not consider the working state of cone visual cells of the fovea of the retina, do not consider the problem of the size change of the simulated far-point and near-point luminous viewpoints, namely the problem of visual angle linkage, and do not consider the linkage of the neural impulse brain provided by the optic nerve center compared with empirical data to participate in analysis and judgment.
However, during the treatment, the highly intelligent computer in the brain, compared with the empirical data, quickly finds: in the above-mentioned change, there is no change in the size of the angle of view, and there is no change in the size of the optotype, and then a sense of justice is produced, and the action of adjustment is abandoned. Because of this, the therapeutic effect of the existing binocular imaging therapeutic apparatus is not well announced or imagined.
More particularly, people now have been overwhelmed by the severe reality, completely forgotten the great potential of the human eye that has been demonstrated, and no scientific method has been developed to fully mobilize the potential.
"according to the measurement result of polyak, the diameter of each pyramidal cell in the central part of the fovea of human eye is 1.0 to 1.5. mu.m. If the population of cells is densely packed, the pyramidal cell spacing is about 1.0 μm. The angle between the two ends of the range is about 12 "to calculate the optimal force of about 3.0. In 1980, the eyesight investigation of 22 students in provinces and cities in China is not rare for students in provinces and cities, the eyesight of which reaches 2.0 (accounting for 24%) and more than 3.0. Foreign reports may even reach up to 6.0, corresponding to only 9.45 "viewing angle". (Xuguangdi ophthalmology dioptric, military science publishers, 2005, page 149)
Thus, the retina has great potential, and normal vision as described by 1.0 is not the highest bound of the human eye.
The invention content is as follows:
the invention aims to: by modifying the luminous viewpoint of the eye disease therapeutic apparatus for myopia and the like, the aims of effectively smoothing brain logic comparison, stimulating micro visual desire, arousing visual cell optic nerve cells and greatly improving the curative effect of the eye disease therapeutic apparatus for myopia and the like are achieved.
Wherein, the eye diseases such as myopia and the like comprise: myopia, amblyopia, strabismus, hyperopia, astigmatism, presbyopia, and nystagmus.
A first contribution of the present invention is to propose the concept of "five linkage" of the visual process for making up for the deficiencies that the "three linkage" of the visual process shows in terms of product design.
In the prior art, when a binocular imaging therapeutic apparatus is designed, the five-linkage of the visual process of human eyes is simplified into: when looking near, firstly, the eyes must be gathered in the visual axis direction, secondly, the adjustment is enhanced, and thirdly, the pupil is shrunk; when the user looks far away, the visual axes of the two eyes are scattered, the adjustment is relaxed, and the pupil returns to the original size or the three-linkage of the close-looking and the far-looking eyes of the enlarged human is realized. Neglecting the last two of the five linkage when the human eyes see near and far, namely, increasing the visual angle when seeing near and decreasing the visual angle when seeing far, and fifthly, the brain judges the distance of the seen object by comparing the nerve impulse caused by different sets and different visual angles with the experience data.
That is, when designing a binocular imaging apparatus in the prior art, all the light-emitting viewpoints are designed to be the same size, the anterior triplet movement of the human eyes looking at near and far is performed as usual in the treatment process, the visual angle is not increased when looking at near and the visual angle is not decreased when looking at far, and the feeling of 'good sight' is generated on the brain compared with the empirical data, so that the curative effect is not as good as the imagination and is also in the philosophy. The product is designed according to the natural law of five-linkage, so that the curative effect can be greatly improved.
The second contribution of the invention lies in the great potential of mobilizing the fovea by the proposition, the setting and the fixation of the secondary substructure of the luminous viewpoint of the therapeutic apparatus in the using process.
The researchers of the invention judge that the optic cell optic nerve cells of the amblyopia patient accepted in the medical science at present are dormant, and the optic cell optic nerve cells of the myopia patient and the emmetropia population with 1.0 vision are also dormant in a large quantity, and only the existing working optic cell optic nerve cells of the existing living conditions and working and learning environments of people can completely cope with the situation, namely, the retina central concave cone cell density of 3.0 can be seen originally and only part of the working optic cell optic nerve cells can maintain the state of 1.0 vision due to no demand and no vision desire. In other words, the vision of the myopia patients or even the emmetropic population with the vision of 1.0 can trigger and stimulate the microscopic vision desire of the user through the arrangement and the fixation of the secondary substructure of the luminous viewpoint in the therapeutic instrument, so as to provide sufficient active light energy supply for the dormant visual cell and the optic nerve cell, awaken the dormant visual cell and the optic nerve cell and greatly improve the vision.
