The cause of myopia is still unclear, so it is very difficult to prevent and treat it, but it does not mean that myopia cannot be prevented. In order to prevent children from developing myopia early, or to slow down the progression of myopia in children who are already nearsighted, I remind parents that children, especially those under 5 years old, should try to reduce the amount of time they spend using their eyes at close range, such as playing the piano, playing computer games, writing, reading, watching TV, and so on. This is precisely the most difficult thing for children to do, which is partly due to the current educational environment and atmosphere in China, and partly due to the importance parents attach to it. Early and excessive eye use in children with low bells can lead to pathological elongation of the eye axis, making myopia irreversible and rapidly developing. For children who are already nearsighted (I am referring to those who are confirmed to be truly myopic after a dilated eye exam at a regular hospital), the most important precautions are still to reduce the amount of time spent in close proximity to the eyes, to pay attention to balanced nutrition, to get enough sleep, and to increase the amount of time spent outdoors as much as possible, all of which are beneficial to myopia control. Here I want to emphasize that once diagnosed with true myopia, especially if 1.00D or more obviously affects vision, you should wear appropriate myopia glasses in a timely manner, some parents think that the more glasses they wear, the larger the prescription, or the more convex their eyes will become, in fact, these situations have nothing to do with wearing glasses, and some parents are psychologically unable to accept their children wearing glasses, so they do not allow their children to wear glasses, and have true myopia but do not wear glasses The children with true myopia who do not wear glasses often have the habit of squinting and tilting their heads, which to a certain extent will compress the eyeballs and aggravate myopia. The best time to prevent and treat myopia is before myopia occurs, and to prevent it before it becomes a disease, children should generally have routine pediatric eye exams from age three to three and a half to achieve early detection and prevention.” For the question of whether myopia can be cured, I would like to clarify to you once again, although I have said many times in various media and on different occasions for this issue, but parents still have the same questions, I tell you that so far in the world true myopia still cannot be cured, even if the glasses are removed after excimer laser surgery in adulthood there is no correlation with the cure, but However, pseudomyopia and visual fatigue can be cured by medication or training with appropriate equipment, and we have found effective ways to slow down the development of true myopia. At present, many parents confuse amblyopia with myopia, thinking that their children’s poor vision is myopia, but in fact a significant proportion of children’s low vision is caused by amblyopia. The definition of amblyopia is: a child with amblyopia who has no obvious organic pathology in the eye, but whose distance vision is lower than that of a normal child of the same age and cannot be corrected due to functional factors. In other words, amblyopic children have no obvious eye pathology, but their vision is lower than normal and cannot be improved by wearing glasses, which is fundamentally different from simple myopia. Amblyopia has a high prevalence rate in different countries and regions, about 3% in China, and according to the projection of the National Strabismus and Amblyopia Group, there are more than 10 million amblyopic children in China. Amblyopia, especially monocular amblyopia, is easily neglected by parents, thus delaying treatment, and amblyopia treatment becomes less effective as age increases. If treatment is delayed beyond the age of 6, it is difficult to achieve a visual acuity of more than 1.0; if it is delayed beyond the age of 12, it is generally ineffective, and these delayed children will have lifelong low vision, which cannot be improved by wearing glasses or any other method, and often affects the monocular function of both eyes. Children with amblyopia are not only limited in their future education and career choices, but their intellectual and psychological development will be affected to varying degrees as they grow up. Therefore, pediatric amblyopia must be treated early, which requires parents to pay more attention to their children’s visual status, and once they find out that their children have low vision, they should go to a regular hospital to see an ophthalmologist specializing in amblyopia as soon as possible, and here I would like to emphasize again that children should have a routine pediatric ophthalmology examination when they are three to three and a half years old, and if they are indeed amblyopic, they must undergo a standardized and The final standard of cure for amblyopia is to achieve normal corrected visual acuity, i.e., normal vision with glasses, not naked eye visual acuity. The final standard of cure is normal corrected visual acuity, i.e., normal vision with glasses, not bare eye vision.
