Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a myopia prevention and control therapeutic apparatus based on a virtual reality technology and a prevention and control therapeutic system thereof.
Background
As society develops, myopia has become a serious public health problem in today's world, particularly in the east asia. The prevalence of myopia has increased over the years, with rates of up to 80% to 90% among students. In china in particular, at least 6 million people suffer from myopia, 80% of which are adolescent children in the obligatory education phase. If myopia is not prevented and controlled, once the myopia is allowed to develop, and finally high myopia is caused, complications caused by the myopia, such as retinal detachment, choroidal atrophy and the like, bring great inconvenience to future learning and living of teenagers and children, and even have extremely adverse effects on the mental health of the teenagers and children. Therefore, how to effectively control the occurrence and development of myopia in teenagers and children has become one of the hot spots of current research.
VR (virtual reality), or simply VR, is a technology that provides immersive sensation in an interactive three-dimensional environment generated on a computer by comprehensively using a computer graphics system and various interface devices for reality and control. The principle of VR glasses is similar to our eyes, with two lenses corresponding to the eyes, but far from the "intelligence" of the human eye. In addition, VR glasses generally divide the content into two halves, and realize the stack formation of image through the lens. At this time, the pupil center, the lens center and the screen (after screen splitting) center of human eyes are often not on the same straight line, so that the visual effect is poor, and the problems of unclear and deformation occur. The ideal state is that the pupil center of the human eye, the lens center and the screen (after screen splitting) center are on the same straight line, at this time, the pupil distance of the lens needs to be adjusted to coincide with the pupil distance of the human eye, and then the picture center is adjusted by software to ensure that 3 points are in a line, thereby obtaining the best visual effect. Some domestic devices are adjusted through physics, and some domestic devices are adjusted through software. It was decided to retrofit existing VR (virtual reality) glasses with virtual reality technology. On one hand, the virtual reality technology integrates multiple technologies such as computer graphics, human-computer interfaces, multimedia technologies, sensing technologies, network technologies and the like, and is a very challenging cross-technology frontier subject in the simulation technology. The system can simulate environment, perception and natural skills to sense equipment, and can generate real-time dynamic three-dimensional vivid images through a computer to effectively simulate real space environment. The light environment during outdoor activities can be accurately simulated. On the other hand, the child ciliary muscle training device can present ciliary muscle training contents in 3D, relax the ciliary muscles of the children and strengthen the accommodation force of the children. Specifically, based on the virtual reality double-screen technology, parallax imaging of left and right eye screens is formed according to the difference of pupil distances of left and right eyes, and a stereoscopic imaging process of binocular vision objects is restored to a high degree; then imitate the depth that human eyes observe the object, simulate the extension content of extending section on the screen of the virtual reality glasses after obtaining the sense of reality, produce the picture depth of 0 meter to infinity, and then through changing the picture content in the virtual reality glasses, realize the regular motion of looking far and near of eyes, temper ciliary muscle effectively, improve ciliary muscle regulating power. Moreover, the eye movement tracking and deflection rendering technology of the device can also realize the setting of the defocusing state of the picture and simulate the principle of testing and matching the orthokeratology lens to prevent and control myopia. Meanwhile, the visual line of the left eye and the visual line of the right eye can be separated by the principle of a homography machine, a near target is observed by the convex lens, and the adjustment is relaxed. Even a picture is drawn by combining the principle of monocular stereopsis, and the visual psychology is combined to see the targets close to the vanishing points and on the assembly lines in the picture as far. In fact, when two eyes see "far", the graphics at "near" are neither blurred nor double-sighted, and vice versa.
At present, the feasible measures for preventing and controlling the occurrence and development of myopia of teenagers and children in the market are mostly considered from the environmental point of view, mainly comprise wearing frame glasses, cornea shaping glasses, using atropine eye drops for dripping, encouraging outdoor activities, establishing good reading habits and the like, and have the following defects:
1. the frame glasses have proved to have no practical clinical significance in the practice of myopia prevention and control.
2. The cornea shaping mirror has higher requirement on sanitation, the eye inflammation can be caused by poor wearing, certain limitation exists, the required prevention and control time is long, and hidden danger exists in the compliance of patients.
3. The atropine eye drops have different degrees of withdrawal rebound and adverse reactions, such as photophobia, blurred vision and the like, for different individuals.
4. Because the current adolescent children have heavier academic tasks, the outdoor activities of 2 hours every day can not be completely realized, and the weather can not meet the requirements of the outdoor activities all the time.
5. Most VR equipment is complex to operate, only adopts single hardware or software support, and the prevention and control effect is not ideal.
