The device specifically comprisesan image light source disk, a pipe sleeve and a driving disk, a color mixing disk set is arranged below the image light source disk, a folding cylinder is fixedly connected to the lower surface of the color mixing disk set, the pipe sleeve is connected to the lower end of the folding cylinder, slots are formed in the outer wall of a movable sleeve at equal intervals, a set building pipe cylindervertically penetrates into the movable sleeve, a limiting loop is placed below the movable sleeve, insertion rods are integrally arranged at the upper surface of the limiting loop, the insertion rodsare inserted into the slots, an air heating disk is fixedly connected to the lower surface of the limiting loop, and the driving disk is integrally connected to the lower end of the pipe sleeve. According to the device capable of preventing and treating shortsightedness, due to a light source inside the image light source disk, light of proper brightness for a viewing image is supplied to the whole device, image paper of a unique image can be placed on the image light source disk for human eye viewing, and the view focal length is determined.

Description

technical field [0001] The invention relates to the technical field of myopia prevention and treatment, in particular to a device for preventing and treating myopia. Background technique [0002] Myopia is a very common eye symptom. Myopia patients generally have poor visibility for things at a little distance, and have problems with blurred vision, blurred vision and double vision. In darker areas, such The visual impairment will become more and more deepened. Modern people generally suffer from myopia, and there are many reasons for myopia. The most important one is overuse of the eyes. When reading, writing or working normally, the sight distance is greatly shortened. Long-term work or study in places where the light line is too bright is also the leading cause of myopia.

Problems solved by technology

[0003] In the modern treatment of myopia, the most direct way is to use laser surgery, but this kind of myopia treatment is not only costly, but also has insufficient postoperative sequelae, which leads to certain risks. The existing myopia prevention and treatment device has the problems of low prevention and treatment effect, more sophisticated stimulation of eye acupoints and massage, and some need to use acupuncture and moxibustion, which brings a very large barrier to use for ordinary people.

[0004] A kind of multifunctional myopia health care treatment instrument disclosed in Chinese invention patent application publication specification CN104352339A, although this kind of multifunctional myopia health care treatment instrument, through artificially creating a dark environment, improves the photosensitivity of human eyes and slows down eye fatigue; 1. Exercise the user's ability to adjust the focus of distance and nearsighted objects; stimulate acupuncture points through high-voltage micro-current pulse electrodes to stimulate the activity of intraocular tissue adjustment. But it cannot simulate a better scene that can relieve eye fatigue, and the bright spots of the light source are flickering in the dark, which is likely to cause dazzling discomfort. At the same time, there are many acupuncture points on the eyes, and the stimulation of the pulse electrode is not clear and concentrated enough.
