How should we properly understand myopia? In fact, the development of myopia is the process of the development of the sclera and the elongation of the eye axis from the early childhood stage to adulthood, a process that can be understood as a normal physical development of the child. In the process of slowly growing the eye axis, the child’s farsightedness decreases and becomes orthokeratology, which we call orthokeratology. If the eye overdevelops and grows, it becomes myopic. The physiological characteristics of the child are: 0-3 years old, rapid scleral development, 3-18 years old, scleral slow development elongation, in this process, if the child receives near stimulation for a long time, the intensity is large, in time the child’s eye habits are very good, the child will enter the orthophoria state early, into myopia state. Prevent myopia some experience: 1. Preventing the development of myopia is more critical than treating it. We want children to be able to control their eye burden well, starting at a very young age. 2. In addition, do not complain too much about your child’s myopia and increase their heart burden. Visual function training is: the use of optical or psychophysical methods to produce a certain cognitive load (usually higher than the daily demand) on the visual system of the eye (including regulation, convergence, eye movements and their associated movements), so as to improve the visual function of the visual system, visual comfort, to improve and repair the purpose of binocular vision abnormalities. 3, for myopic children no matter what institutions for treatment and training, please believe that clear vision will help children to control myopia, we often see such examples, children myopia without glasses, do not do any treatment simply by reducing the load, the child myopia can not be cured, but rapid development. What supports this theory from medical experiments is the out-of-focus theory, where blurred images stimulate the growth of the eye axis. So myopia if more than 100 degrees, the child a meter away from the thing began to blur, then the child’s daily life clear imaging all in the near distance, we recommend that children need to wear glasses. 4, the theory and development of controlling myopia: When we were surprised to find that keratomileusis can effectively control myopia, a large number of experimental studies over the past decade or so have focused on asking whether it is effective and asking bit what is effective? Nearly 10 years ago, the theory of peripheral defocus began to be put forward, arguing that the eye sees clearly while the peripheral part is imaged in front of the retina, which can inhibit the growth of the eye axis. When this theory was validated, people began to use the theory to explain why our glasses would increase the rate of myopia development? Because of peripheral hyperopic defocus? Peripheral imaging posterior to the retina? So there have been peripheral defocus control frames such as Zeiss’s Growing Joy and Medecor, developed by Professor Chu Renyuan, who took the lead. From not being clinically recognized to the data verified on children in the past 4-5 years, parents have finally found a ray of hope to control myopia. 5. Research on medications for myopia control: Many parents and doctors believe that astigmatism medications can control the development of myopia. Indeed, at the molecular level of scleral growth we have found that M receptor blockers can inhibit excessive scleral growth. But there are many reasons why these myopia-controlling drugs have not been widely used in clinical practice. On the one hand, the operability of daily ordering for children is not particularly high, and on the other hand, atropine is licensed in high concentrations on the mainland, which children metabolize very slowly, causing problems such as photophobia and difficulty in seeing close. Low-concentration atropine still has the problem of dilated pupils and cannot be licensed on the mainland. Some doctors have started to use color-changing glasses + progressive multifocal glasses to achieve myopia control at the same time, but they are still not popular. In addition to poor operability, there are individual differences in the structure and function of the child’s atrial angle, and it remains to be verified whether long-term use of pupil-dilating medication has an effect on intraocular pressure. 6.Personalized lens control program to improve the control effect: There are differences in the human system, and the eye system is also different. Now that the development of visual function tests is starting to gain popularity, we can better understand the visual function of different children’s eyes through comprehensive functional tests and choose different treatment plans through function. 7. Load reduction, good habits, dietary intervention and outdoor activities are enhanced to help control myopia.
