Description

VR-based refractive training equipment

Technical Field

The invention relates to the technical field of ametropia correction, in particular to VR-based refractive training equipment.

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, it may cause irreversible damage to vision function when pathological myopia develops. 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 many people with strabismus, amblyopia, hypermetropia and astigmatism, which have great influence on the visual function. The main reason for myopia of young children at the present stage is to use eyes for a long time at a short distance. 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.

Disclosure of Invention

It is an object of the present invention to overcome the deficiencies of the above-described techniques and to provide a VR based refractive training apparatus.

In order to achieve the purpose, the invention adopts the following technical scheme: a VR-based refractive training device characterized by: comprises an outer cover, a circuit board, a display screen, a lens, a film placing disc, an additional lens, an electric acupuncture point massager, a silica gel layer and an adjustable elastic band; the outer cover is of a structure with an opening at one end, the silica gel layer is fixedly connected with the opening end, the circuit board, the display screen, the lens, the sheet placing disc, the additional lens and the electric acupuncture point massager are all wrapped by the outer cover, and the adjustable elastic band is connected with the outer cover; the additional lenses are respectively fixed on the rotatable film placing discs on two sides, and the purpose of changing the refractive state of the eye is achieved through the change of the additional lenses; a heating film and an electric acupuncture point massager are arranged in the silica gel layer, and two windows are arranged on the silica gel layer at intervals; the electric acupoint massager consists of an electromagnetic vibrating head and a slide rail and is connected with the circuit board. Preferably, the display screen is any one of the following devices: cell-phone, panel, computer.

Preferably, the electric acupoint massager is moved by the sliding rail to cover the orbital margin of the eyes and nearby acupoints; the electric acupoint massagers are divided into 4 sets of upper and lower sides of the eyes. Preferably, the additional lenses total 4 lenses and 2 lenses on both sides, and the refractive powers of the additional lenses are respectively: +1.50D, -1.50D.

Preferably, the lens placing disc can be taken out of the outer cover to replace the additional lens.

Preferably, each sheet placing disc has 3 sheet placing positions, and the center of each sheet placing position can pass through the window by rotating the central shaft of the sheet placing disc.

Preferably, each side of the film placing disc is provided with 2 lenses, 1 film placing position is left, and a black shading film can be inserted into the idle film placing position after the film placing disc is taken out through the outer cover.

The invention has the beneficial effects that: the invention adopts VR, diopter conversion, acupoint massage and other means, and adopts a 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 also has direct help for hyperopia, astigmatism, strabismus and amblyopia. By adopting the additional lens, the fixation focal distance is changed, the ciliary muscle is subjected to contraction-relaxation alternate change, the ciliary muscle adjusting capacity is enhanced within a limited time, and the eye relaxation is far better than that of the eye relaxation by watching a long distance. The interest of users, especially young children, is attracted through VR, the adhesion of the VR 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 occurring 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 and the modern method, the eye adjusting capacity is effectively improved, the eye muscle fatigue is relieved, the myopia is prevented and relieved, and the direct effects on hyperopia, astigmatism, strabismus and amblyopia are achieved.
