I. Overview.
At present, the core instrument used in vision care (rehabilitation) centers throughout the country in small and medium-sized cities that can significantly improve naked eye vision is the Visualization System. It can bring significant social and economic benefits, mainly with its ability to improve 100 to 300 degrees of myopic naked eye vision to about 1.0 within 1 to 2 months. Therefore, it is highly valued by all vision rehabilitation center franchises and the ophthalmology community. The 3rd-4th generation of this system is introduced by Professor Liu Dongguang western technology and improve it, significantly improve the performance and reduce the cost, very suitable for franchises, optical stores, grassroots hospitals and myopia patients family use.
Second, structural features.
Composed of three major systems, namely, the distant chemical box, the focus sensitive box and the control panel.
(A) eyepiece box: by the focusing eyepiece (automatic telemeter or comprehensive optometry “bull’s-eye”) and strengthening device (anti-myopia) consists of.
1.Focusing eyepiece: can neutralize the refractive error of the eye, and can produce 0~500 degrees of farsightedness fogging or myopia focusing by manual or automatic focusing.
(2) Strengthening device (anti-myopia): including visual field expander, auricular acupuncture apparatus, same frequency harmonic lamp and other strengthening anti-myopia devices.
(B) Adjustment – collection box: consists of control box and sight marker box.
1, control box: with the visual marker box to complete the focus sensitivity and amblyopia training. The control box can be connected to CAM instrument, light brush instrument and other vision enhancement devices.
2.Sight marker box: It can provide 18~42 training icons and color markers for myopia prevention and vision enhancement training.
(C) control panel: consists of functional panels (focus box panel, eyepiece box panel) and PCB computer integrated circuit. It can produce 7 kinds of functional modules to automatically control the training program and produce the most optimal effect of myopia prevention and vision enhancement. At the same time, it can simplify the operation of trainers, which is favorable to popularization and family promotion.
III. Main functions and principles
(A) Basic myopia prevention functions.
To offset myopia 2 key links: that is, to offset the near “back out of focus”, “back focus” imaging link to prevent myopia
1, offsetting the near “back defocus” that is, the first key link in the development of myopia: through the bull’s-eye for far-sighted film or automatic distant lenses, offsetting the near, and blocking the first key link of myopia: the retinal periphery “back defocus”.
(1) manually turn the lens on the bull’s-eye, can turn out the foggy lens of hyperopia, causing foggy vision or front defocus state of hyperopia, promoting excessive relaxation of intraocular muscles and flattening of the lens, so as to improve hyperopia.
(2) Automatic farsighted lens auto-zoom, can produce a gradual increase of 300 ~ 500 degrees of farsightedness fogging, can significantly improve the farsightedness. 2, offset the near “post-focus” that is, the second key link of myopia pathogenesis: to provide adjustment – collection sensitivity training, improve eye adjustment sensitivity, thereby blocking the second key link of myopia “post-focus” (i.e. adjustment lag). When myopic eyes are near for a long time, the lens focus will be “frozen” in the near, which can lead to the inability to relax and become far when looking at distance, resulting in a decrease in distance vision.
(ii) Strengthen the function of myopia prevention.
(1) It can provide visual field enlargement training to counteract the myopia of form deprivation when looking at the near, thus strengthening the anti-myopia function (when looking at the near, the closer you look, the smaller the visual field, the more serious the form deprivation, and the more likely to cause myopia).
(2) Electro-acupuncture stimulation of auricular points can be provided: through meridian stimulation, the auricular points of the eye are activated to strengthen the anti-myopia effect.
(C) auxiliary vision enhancement function principle (to improve naked eye vision): that is, 1, 2, 3 vision enhancement function principle
1, 1 line of regulation – collection sensitivity training, improve the focus sensitivity of seeing far and improve distance vision.
2, 2 kinds of visual cell sensitivity improvement: that is, the retina and the visual center of the visual cell sensitivity increased and increased visual acuity.
3, 3 kinds of contrast visual acuity training.
(1) retinal RGY three visual cell sensitivity stimulation.
(2) Provide CAM instrument visual center sensitivity stimulation to increase visual cell sensitivity.
(3) Provide other amblyopic vision enhancement functions (red flash, light brush, fine visual acuity, etc.)
(4) Sub-generation function (i.e. advanced sub-generation): Optimization system belongs to 4~5 generations of products in myopia instrument family, which itself can also be divided into 5 generations.
The first generation of optimization system: adjusting the visual marker manual type movement, manual type farsightedness eyepiece. (Such as the oldest model of the optimizer).
The 2nd generation of optimization system: automatic movement of adjusting visual markers: such as the optimizers used by Dr. David, Heart Vision, Seven Days Up, Minebea, and Huaya.
The 3rd generation of optimization system: adjusting the programmed movement of the visual standard: such as Dr. Eye 3 generation optimizer.
The 4th generation optimization system: 3rd generation + automatic farsighted eyepiece + visual field expansion, ear acupuncture points + light grids, light brushes, such as Dr. Eye 4 generation optimization instrument.
Fourth, the scope of application.
1. Myopia prevention for students who “look close”.
2.Myopia prevention for students with one parent with high myopia.
3.Students with mild myopia who do not want to wear glasses.
4, students with rapid myopia development.
5. those with high myopia developing continuously
6.Treatment of various kinds of amblyopia (including refractory and personalized);
7.Personalized treatment for refractory amblyopia.
