Eye column stereoscopic vision training

In the 10 years when China's eye care industry rose, there were countless products with good myopia prevention and treatment theory. Some parents bought four or five sets of this "magnifying glass", "physiotherapy mirror" and that "therapeutic instrument". After buying home, most of these products were shelved because they didn't insist on using them. As the earliest eye care enterprise in China, Mr. Fan, the general manager of Beijing Jiacheng Vision (Group), once had an inspiration about the prevention and treatment mode of myopia, that is, whether an instrument as smart as a house can simulate many ways that are beneficial to the eyes, so that many children can sit in it to receive health care and achieve the purpose of protecting their eyes like eyes. Because there is no need for external intervention, children supervise each other, and it is easier to stick to the eye protection method, easier to master the eye protection process, and the eye protection effect is more transparent. Relying on the powerful technical research and development strength of Beijing Jiacheng Shixin Myopia Prevention and Treatment Research Center, his idea came true, which is the space vision training system.

"Space Vision Training System" is a full-color light-emitting system established by hundreds of groups and thousands of light-emitting diodes. The operation of the system is controlled by a computer chip, which can display a variety of colors, and guide users to make more than ten or even dozens of intraocular and extraocular muscle movements/exercises according to the pre-established methods of software programs.

Principle: wolman and others pointed out that long-term close reading and writing is a special form of deprivation. When reading at close range, only the fovea of the retina can get enough visual stimulation, while most other parts of the retina lack enough stimulation, so the activity of most retinal cells decreases. In the early fundus changes of myopia, the retinal anemia around the fundus is yellowish white, that is, the phenomenon of "non-oppressive white". Fluorescein angiography showed that the blood circulation speed of retina and choroid slowed down, and insufficient blood supply led to diffuse or localized atrophy of retina and choroid, and the distribution of pigment was disordered.

Spatial vision training system is to exercise the eye muscles and stimulate the retina in the surrounding area through rhythmic and large-scale eye-looking and side-looking movements with eyes following various lights. It is mainly to balance the visual stimulation to the retina, and pay attention to finding peripheral vision while emphasizing exercise. Its purpose is to strengthen the visual stimulation of peripheral retina and improve its cell activity. For example, if the visual stimulation of retina is balanced, the two factors that it secretes to control scleral growth and inhibit scleral growth will also reach a relative balance, thus controlling the occurrence and development of myopia. Li recently measured the systolic peak velocity and resistance index of ophthalmic artery in 50 myopia patients and central retinal artery in 265438 0 patients by color Doppler. Compared with before and after this method, the blood flow in the eye is increased and the circulation is accelerated, which is definitely beneficial to improve eye nutrition, optimize the internal environment of eye tissue and promote visual rehabilitation. When reading and writing at close range, the eyeball is limited to turning inward, downward and upward, resulting in overload of the regulating muscles and converging muscles; At the same time, there is little chance to rotate outward, upward and downward, which leads to the failure of the upper and lower oblique muscles and the lateral rectus muscle.

Myopia is formed by using the eyes too close. Spatial vision training system guides users to exercise their eye position and participate in the movement mode of extraocular muscles, which is rarely used in the process of using their eyes at close range such as reading and writing. This kind of eye position eye muscle training aimed at "myopia formation route" is undoubtedly of great significance to myopia prevention and control. Interactive gaze visual training system is an exclusive eye bar function module created by Jiacheng Eye Bar Working Group, which combines many modern myopia prevention and treatment theories, children's educational game principles and writing methods. After years of technical reserves. Interactive gaze system software is also one of the few computer software used for visual training in the world.

Under the premise of strictly maintaining the efficacy of eye protection, the system has carried out bold functional link innovation, completely breaking away from the traditional boring and difficult long-term eye protection method. The system applies the most popular 3D rendering technology, and the Origo Engine 3D engine adopted is the first high-quality 3D engine independently developed in China.

In operation, the user puts on a special eyepiece, makes a correct judgment according to the "E" visual targets that appear in turn at different time intervals, different backgrounds, different opening directions and different viewing angles according to certain rules given in the projection screen, and then determines the input through the input handle. Until the user's vision limit is reached, the "staring method" training process will be carried out, and a certain staring time and palm print reading time will be specified in the "staring method".

The system has designed different use modes such as "staring method" training mode, various extreme challenge modes and various multiplayer modes, with rich and colorful contents. At present, the system can be used by four people at the same time. With the participation of partners, users will not feel lonely.

Second, the principle of the nearest point that the human eye can see with the maximum adjustment force is called the adjustment near point. The closer the adjustment point is, the stronger the adjustment force is. The farthest point that the eyes can see clearly is called the far point. The farther the far point is, the better the far vision is (the far point facing the eyes is at infinity). In medicine, the distance between the far point and the near point is called the adjustment range.

The function of ciliary muscle in myopia is generally decreased, which is characterized by the decrease of relative accommodation reserve and the extension of accommodation reaction time. The telescopic gaze state in the interactive gaze visual training system relies on its own efforts and concentration, thus effectively relieving the spasm and unresponsiveness of the ciliary muscle and greatly relaxing the ciliary muscle; The time of 10 second set in "eye column fixation" makes the ciliary muscle contract greatly, and the relaxation and contraction are combined to form a large-scale crystal movement, which is advocated by many ophthalmologists (such as Professor Xu Guangdi). Compared with the traditional crystal practice, the far-near alternating gaze in the interactive gaze visual training system has a greater force on the adjustment system and a more lasting effect. Persistence in the use will continuously expand the operator's adjustment range, making the adjustment near point closer and the far point farther. Persistence will improve the far vision. Professor Xu Guangdi, the inventor of "Shu Eyepiece", is a famous bending eye expert in China and devoted himself to aviation vision research in his early years. In the 1960s, pilots of China's Air Force found that when flying at high altitude, they were prone to air myopia, which greatly shortened the sight distance of pilots and directly affected their combat effectiveness.

In order to overcome the influence of high-altitude myopia on pilots' vision, the expert group headed by Professor Xu Guangdi, with the strong cooperation of the Air Force, designed a binocular combination method after years of experiments and exploration, which solved the influence of pilots' aerial myopia and improved the combat effectiveness of the Air Force. "Shu eyepiece" is developed on the basis of "binocular combination method"

Shu eyepiece is a high-tech product led and guided by Professor Xu Guangdi personally, which lasted for more than one year. In the smallest space and the shortest distance, it can be legally used by both eyes, and it adopts advanced optical and electronic technologies at home and abroad. It is a national second-class medical device. Approval number: Guan Xie (Zhun) Zi 2003 No.2260060. Shu eyepiece has been protected by national patent, with patent certificateNo. ZL02202998.2. According to human visual physiology, when people look near, their eyes will converge inward, their accommodation will be enhanced and their pupils will be narrowed. In hyperopia, the visual axes of both eyes are scattered, and the adjustment is relaxed, and the pupil returns to its original size or increases. This phenomenon is called the triple movement of seeing near and seeing far.

Triple movement

(1) Shu eyepiece uses binocular combination technology, and simulates the far target with the near target, so that our eyes can get coordinated exercise of seeing far and near in the near target environment, and the ciliary muscles can be fully relaxed, thus achieving the effect of treating pseudomyopia and preventing its recurrence.

(2) The eyepiece adopts a new spot target and a specific blinking time and rhythm, which can improve the visual function of human eyes to the greatest extent in a short time, so as to effectively inhibit the occurrence and development of true myopia.

(3) In the process of using the eye-relaxing eyepiece, the eyes can involuntarily follow the light spot target to move up and down, left and right, fully exercise the eye muscles, promote the blood circulation of the eye tissues, strengthen the peripheral function of the eye, effectively relax the excessively tense ciliary muscles, and gradually expand the field of vision, thus achieving the effects of eliminating visual fatigue and improving eye health care.

(4) Improving binocular fusion function and establishing stereoscopic vision quickly can also improve vision.

(5) Stimulate the red and green light spots of the eye mask to stimulate the foveal cone cells of yellow retinoid and improve visual sensitivity.
