Many parents with children with glasses, often like to provide their own “experience”. However, many of the experiences of parents, in the opinion of professionals, are “misunderstandings”. If you are not nearsighted, you must know a few friends with nearsightedness. Not long ago, the release of the “national visual health” research report shows that: at present, every three people in China have a myopic eyes, of which the proportion of school-age children and adolescents myopia is much higher than the proportion of the whole population of myopia. According to age, the prevalence of myopia in people born before the 1970s is only 20% to 30%, but for teenagers born after the 1980s, the prevalence of myopia has increased to more than 80%. For teenagers, the best way to correct myopia is to wear frames. At present, China has to dispense 100 million eyeglasses a year! Many parents with children with glasses, often like to provide their own “experience”. But many of the experience of parents, in the view of professionals, are “misunderstanding”. Misconception 1: glasses of lower degrees of good Experts: long-term visual fatigue will accelerate the development of myopia. Xiao Zhe’s parents are highly myopic. The mother’s eyeglasses are as high as 800 degrees, and the father’s eyeglasses are 600 degrees. After Xiaozhe was born, both of them made up their mind to let their children prevent myopia. They thought of many ways to prevent myopia, and one of the toughest ways was to never watch TV in the house. Since Xiaozhe was born, the family “quit” TV. Not only the children do not watch TV, the old people who help to bring up the children are also not allowed to watch TV. Despite this careful protection of Xiaozhe’s eyesight, he became nearsighted in the third grade and wore glasses. Today, Xiaozhe is in fifth grade and his glasses have gone up to 400 degrees. Xiaozhe’s mother’s wish now is: I hope it doesn’t develop into high myopia. Whenever Xiaozhe’s mother takes her child to get glasses, the last thing she wants to see is the increase in prescription. Therefore, every time Xiaozhe gets glasses, Xiaozhe’s mother will repeatedly say to the optometrist, “You don’t have to correct us to 1.0, lower the prescription, or the prescription will go up too fast!” Is it better to have a lower prescription for eyeglasses? The expert of Beijing Tongren Hospital Optometry Center said that when young people get glasses, if they don’t feel uncomfortable, the corrected visual acuity should be 1.0. Some parents think that the child’s seat is in the front anyway, and the glasses don’t need to be especially clear; some parents are worried that if the prescription is high, the prescription may go up even faster in the future. Tongren Hospital experts said, teenagers and adults are different: adults generally eye development stops, prescription lenses when they confirm that they can see clearly enough, no discomfort; but teenagers daily life learning on the higher requirements of visual acuity, the eyes are still developing, so it is recommended that the corrected visual acuity up to 1.0. 1.0 is just normal vision. ” The principle of myopia prescription is the lowest degree of best-corrected visual acuity, that is, the first prerequisite is the best-corrected visual acuity, “Parents make the decision to choose a lower degree for their children, the children sometimes see a more blurred image, which in the long run may be more likely to cause eye fatigue, leading to the development of myopia; of course, overcorrected degree will also cause visual fatigue, so the prescription of prescription glasses before the optometry is very important. The optometry is very important.” Myth 2: Pupil dilation medicine has side effects Expert: Without pupil dilation, the side effects of prescription lenses are even greater. 6-year-old YaYa in the school’s routine physical examination, was checked out vision problems. The teacher sent a notice to the parents of Ya Ya: take the child to the hospital to review. At the hospital, the doctor checked that the child’s vision was normal. But YaYa’s mother still do not feel at ease, on the way home, she passed by an optical store, by the way to do a computerized optometry. The results of the YaYa mom was shocked: her daughter was even 300 degrees myopia! Ya Ya’s mom took her daughter back home and stopped talking. She told a friend on WeChat that after seeing her daughter may be myopic 300 degrees, her heart “pulled out cold”. “So small on the myopia 300 degrees, the future glasses degree does not develop to 1000 degrees! Girls with a thick glasses, ugly not to mention, there may be many complications in the future, perhaps the retina will also fall off! The more YaYa’s mom thought about it, the sadder she got, and she didn’t know what to do. Later, a friend reminded her that it was better to go to the eye hospital for a checkup. With a hint of luck, YaYa’s mom came to the hospital’s ophthalmology department for an eye examination. The optometrist said that children’s optometry must be dilated. Ya Ya’s mom saw a bunch of side effects on the dilation medication and didn’t want to dilate her daughter’s pupils. But the optometrist insisted on giving the child dilated pupils, dilated pupils and then optometry, the doctor told her that the child is not only not myopic, but also farsighted 300 degrees! “We recommend that children under the age of eight or nine should have their pupils dilated slowly for the first time, and older children should at least have their pupils dilated quickly for the first time.” Peking Tongren Hospital experts said that the smaller the children’s eyes, the stronger the ability to regulate, sometimes the child “myopia” is actually ciliary muscle spasms, after the use of pupil dilating drugs, ciliary muscle relaxation, the child may not be “myopia”, “This is what we call myopia”. “This is what we call pseudomyopia.” Parents who are reluctant to allow their children to use astigmatism are often encountered, and these parents are mainly concerned about the side effects of astigmatism. In fact, the commonly used astigmatism is very safe, the vast majority of children will not appear obvious side effects, such as slow dispersion of the use of 1% atropine sulfate, only a small number of children will have facial flushing, low-grade fever and other symptoms, drink a lot of water during the use of medication, after stopping the drug, these symptoms will disappear. But do not dilate the pupil with glasses, for the child “side effects” is greater. Myth 3: Frequently wearing glasses will become ugly Expert: Wearing glasses has nothing to do with eye deformation. Lele is in her first year of high school this year, and she wore glasses the year she graduated from elementary school. Although her glasses have now reached 350 degrees, but as long as not in class, Lele insisted not to wear glasses, the reason is: wear glasses will be the eyeballs “suck” out, grow into “goldfish eyes”. Many of Lele’s classmates don’t like to wear glasses. Often a group of girls get together and look at each other with narrowed eyes. Walking in the corridors of the school building, students are quite “lonely”, “ignore each other”. In fact, they are all nearsighted and can’t see well from a distance. Many girls who love beauty don’t like to wear glasses, thinking that they will become ugly. Will wearing glasses make you ugly? Experts from Beijing Tongren Hospital said that myopic glasses are concave lenses, and after wearing glasses, you will see other objects become smaller; when others look at the eyes of myopic patients through the lenses, they will also feel that the eyes of those who wear glasses are small. In addition, the smaller field of view with glasses causes myopic people to use afterglow less often, “because the afterglow is beyond the scope of the lens, and it’s hard to see.” People who don’t use afterglow don’t have as lively eyes, so the person looks more wooden. These are the reasons why nearsighted glasses can make people “ugly”. As for wearing glasses will make the eyeballs convex, there is really no scientific basis. In addition to facial development and ethnicity, “goldfish eyes” are also closely related to myopia itself. This is because myopic people are generally axial myopia, high myopia is the eye axis growth, when the eye socket can not accommodate the growth of the eyeball, the eyes will be convex outward, “but wearing glasses itself and eye deformation has nothing to do.” For elementary and middle school students, the point of wearing glasses is mainly to make themselves see better. “The amount of information people get through their eyes accounts for 80 to 90 percent of the total amount of information we get, so you’ll miss a lot of excitement if you don’t wear glasses.” Wu Min said, at present, primary and secondary school students with myopia, the most safe and effective way of correction is still wearing frames; of course, children can also wear contact lenses, but soft contact lenses, that is, common contact lenses on the market, oxygen permeability is poor, may cause eye inflammation, children should try to wear less, the best to wear; there are also some special contact lenses with high oxygen permeability, such as keratoplasty lenses or rigid oxygen permeable cornea There are also some special high oxygen permeable contact lenses such as keratoplasty or rigid oxygen permeable corneal contact lenses, etc., which have better oxygen permeability, but the fitting requirements are high, and the requirements for the wearer are also very high, so it is necessary to go to a regular medical institution for fitting.
