Description

Myopia training equipment based on VR

Technical Field

The invention relates to the technical field of myopia correction, in particular to myopia training equipment based on VR.

Background

The number of myopia people in China is about 4 hundred million, wherein the number of myopia people in young and young people is about 2.7 hundred million, and the myopia people tend to increase year by year, which has serious influence on physical and mental health. Furthermore, if myopia is allowed to progress, irreversible damage to the visual function may occur when pathological myopia progresses. Therefore, the prevention and control of the myopia of the young and the young are more and more concerned and valued by the whole people. In addition, there are a lot of squinting and amblyopia patients, which have great influence on the visual function.

The main reason for myopia of young children at present is long-time short-distance eye use. This unhealthy eye condition results in the continued contraction of the ciliary muscle in the eye to focus the near target, and over time, the ciliary muscle relaxes less, the elastic recovery of the lens decreases, and myopia develops. This can only be avoided by continuously alternating the contraction and relaxation of the ciliary muscle. The traditional method is not suitable for the myopia group due to the monotonous object of fixation. And Virtual Reality technology (VR) is used as a carrier, and abundant contents of the VR is enough to mobilize the enthusiasm of young children, so that the VR can be matched with the young children to smoothly complete related training. Meanwhile, as eyes generate triple motion of adjustment, integration and pupil contraction when watching a target, the eyeball needs to move in all directions during exercise, so that the training effect is better, which is exactly the long item of the panoramic VR, and a large enough visual field can be generated through a large wide-angle projection screen to meet the requirement of full rotation of the eyeball in all directions.

At present, VR concepts are introduced to the market for refractive training, but the far and near change presented by VR pictures is not the change of a real fixation point, only the size is changed, but the focus of fixation is not really changed, and the effect of driving ciliary muscle contraction-relaxation regulation cannot be achieved.

Eye massage is to achieve the purposes of relieving eye fatigue and improving the refractive state by stimulating the acupuncture points of the eyes according to the traditional Chinese medicine meridian theory, but the eye massage instruments on the market are monotonous in measure at present, most people cannot use the eye massage instruments for a long time, and the single massage effect is not ideal.

The invention has the beneficial effects that: the invention applies VR, focus changing, acupoint massage and other means, and adopts comprehensive training method for ciliary muscle, extraocular muscle and acupoint channels and collaterals of eyes to improve the eye adjusting ability, thereby preventing and relieving myopia, and simultaneously, the invention is also directly helpful for strabismus and amblyopia. The distance of the virtual image formed by the display screen is changed by moving the lens, so that the focus of the human eye is changed, the ciliary muscle is subjected to contraction-relaxation alternate change, the ciliary muscle adjusting capability is enhanced within a limited time, and the method is far better than the method of relaxing the eye by simply overlooking the distant place. The interest of users, especially young children, is attracted through VR, the adhesiveness is increased, and the using effect is improved; meanwhile, the characteristics of VR super-large wide angle are utilized, and VR game programs are combined, so that eyeballs can fully rotate in all directions, and extraocular muscle fatigue caused by triple movement at the near vision position is relieved. By means of the photoelectric effect produced by VR game program and the focal length change, the development of optic nerve is stimulated to cure amblyopia. The eye acupuncture points are precisely massaged by a meridian massage method through the matching of a slide rail and a program control, and various physiotherapy means such as magnetotherapy, thermotherapy and acupuncture points are implemented by using the modern electronic technology through hot compress of a heating film, so that qi and blood are regulated, meridians are warmed and collaterals are dredged, and the eye health care is improved. By combining the traditional method with the modern method, the eye adjusting capacity is effectively improved in the shortest time, the eye muscle fatigue is relieved, the myopia is prevented and relieved, and the direct effect on strabismus and amblyopia is achieved.
