Automatic distance glasses are the most ideal control method for students’ myopia, because they work well for the main characteristics of students’ myopia. With the rapid development of the electronics industry, myopia has become the most serious eye problem for young people and a big problem for thousands of parents. Myopia wearing glasses is a small matter, anyway, these days students are wearing, look also have a bookish, but myopia degree development too fast directly to the child’s life brought adverse effects is a big deal. So, how to effectively control the development of myopia, to achieve the effect of treatment of myopia? A student myopia 5 characteristics 1, the main reason is to look close, especially to watch TV computer book. Look close is the main motive of myopia occurrence and development. As a kind of focal distance mirror, the automatic distance mirror can effectively control the problem of nearness. 2, the vast majority of mixed myopia, that is, in the axial myopia mixed with regulatory tension myopia, which is also the main reason why students must go to the hospital for myopia dilated eye examinations to remove the regulatory tension myopia before myopia can be diagnosed. This situation requires that the treatment of myopia be based on farsightedness and also on the exercise of the adjustment ability. 3. Rapid development, with an average increase of 100-150 degrees per year, is mainly related to too many opportunities to “look close” and poor self-control of the child. The nearness is mainly caused and aggravated by two key links: (1) the nearness reflex link (i.e., when looking at the nearness through the neural reflexes to form a regulatory myopia and a narrowing of the pooled visual field, which can induce biochemical changes in the eye and eye axis lengthening, with each 1mm increase of about 300 degrees of myopia. (2) Continued eye sensitivity decline link, that is, long-term look at the near secondary to the eye to see far, look at the near, or look around when the focus sensitivity is slow, can lead to intraocular biochemical changes and eye axis lengthening, each long 1mm about 300 degrees of myopia. 4, general myopia instrument control is ineffective: because most myopia instruments can neither offset the look-near reflex nor improve eye sensitivity. 5, need long-term persistence to get good results: as we all know, myopia is a long-term formation, its prevention and treatment also need long-term persistence to be effective. However, so far there is almost no myopia instrument can attract students to consciously adhere to the long-term use, so the long-term effect is not good, which is perhaps the main reason why the majority of myopia instrument effect is not good. Second, look near mainly through two key links to cause and aggravate myopia: 1, near the reflex link: that is, look near the time by the neural reflexes formed by the regulatory myopia and pooled visual field narrowing, can induce changes in the eye myopia-related factors, resulting in the eye axis becomes longer, each long 1mm about 300 degrees of myopia; 2, eye sensitivity decline link: that is, long-term look near secondary to the eye focus solidification or focus sensitivity decline, performance This can directly lead to changes in the myopia-related factors in the eye and a lengthening of the eye axis, with each 1mm increase of about 300 degrees of myopia. Any method to prevent and control myopia must offset or block the above two key links to obtain good long-term results. It is the most ideal eyewear to prevent and control myopia in students because it is the only eyewear that can block two key aspects of myopia: its manual focus can neutralize the original 0~500 degrees of myopia in students, and offset 30~300 degrees of regulatory myopia caused by 30~7500px of TV and computer, thus blocking the first aspect of myopia (regulatory myopia formation). ). At the same time, the virtual teleoptic mirror can solve the problem of peripheral field back out of focus when looking close. In this way, the auto-teleoscope controls the two key links that deepen myopia, and is naturally effective in treating myopia. To conclude, the automatic telephoto mirror targets the key aspects of myopia in students, treats myopia at its root, and can firmly control the development of myopia, making it the best choice for students who need to look at near for a long time to treat myopia.
