Children are short-sighted. Some factors startle you!!

Abstract: in medical research, it is found that when noise acts on auditory organs, it will also “spread” to visual organs through the action of nervous system, so as to weaken people’s vision. In short, noise can reduce the sensitivity of human eyes to brightness.

when it comes to myopia, it’s a matter that parents strictly guard against and absolutely don’t want to happen to their children, but there are still more and more small glasses around. What’s the reason? Recently, there are many new statements: the causes of myopia are not only unsanitary eyes, but also many wonderful reasons you can’t think of! Don’t say don’t know, the world is really wonderful, let me tell you the same!

and

killer 1: the survey of

and

found that children who like to eat dessert and drink soft drinks are more likely to have myopia, and drinking more milk can delay myopia. In this regard, Zhang Peibin, chief physician of the children’s eye health center of the children’s Health Department of the maternal and child branch of Jiangsu Provincial People’s Hospital, explained that the metabolism of sugar in sweets and carbonated drinks in the human body requires a lot of vitamin B1 and reduces the content of calcium in the body. Calcium is the “protector” of eye tissue. Lack of calcium in the body will not only reduce the elasticity of the eye retina The increase of pressure in the crystalline body and the elongation of the anterior and posterior diameter of the eyeball can also cause degenerative lesions in the cornea and ciliary muscle, so as to weaken the elasticity of the eyeball wall and promote the deepening of myopia.

in addition, eating too many sweets will also lead to the increase of blood glucose, plasma osmotic pressure, aqueous humor and lens osmotic pressure. Once the lens convexity and diopter increase, myopia will also come to the door.

countermeasures:

touch less sweets and drink more milk. Milk can supplement calcium, which naturally increases the “protection ability” of eye tissue.

Killer 2: noise

we all think that noise will have an impact on hearing and psychology, but we never expected that noise will also affect vision, especially for children who are still in the stage of eye development.

and

have found in medical research that when noise acts on auditory organs, it will also “affect” visual organs through the action of nervous system, weakening people’s vision. In short, noise can reduce the sensitivity of human eyes to brightness.

countermeasures:

try to reduce the volume when using household appliances or talking. For example, when watching TV, try to adjust the volume to the lowest; When washing clothes, close the door of the toilet; When choosing new household appliances, in addition to being beautiful and practical, noise is also one of the judges; When the kitchen is not in use, the door is closed; When family members talk, try to ease their tone, etc. The third killer of

: learning the piano too early

and

, known as the king of musical instruments, have always been the first choice for parents to cultivate their children’s temperament and sentiment. This summer vacation, the piano interest training class is also full of people. However, recently, a saying that “the piano hurts the eyes the most” has spread among parents. Friends remind that playing the piano will hurt the eyes, “you must never practice the piano for your children again”! Is that really the case?

and

at present, there is no epidemiological statistical data to prove that there is a direct relationship between piano practice and myopia. From our clinical reception, myopia is indeed more common among piano children. Usually, preschool children’s eye development is in the golden period, and children’s vision is not fully developed and mature. Practicing the piano too early without paying attention to protecting eyesight, children have a high probability of myopia. Moreover, the characters of the piano score are usually relatively small. When children practice the piano, they look at the piano score and the keyboard, and they look at it from a close distance for a long time, which is more likely to make people feel tired. Premature and long-term excessive piano practice will accelerate the development of eyeball emmetropia and consume the original hyperopia too early. If it is not corrected in time, children are more prone to myopia. Also, if both parents are highly myopic and have a family history of high myopia, the child has a high probability of myopia.

and

in short, it seems that practicing the piano causes children’s myopia. In fact, there are many factors behind it, such as children practicing the piano too early, using their eyes too much at close range, and finally children’s myopia.

and

children’s eyesight is relatively fragile before the age of 6. Therefore, it is not advocated to let children use their eyes too early, such as learning to read characters, learning musical instruments and reading piano scores, which are likely to make children myopia too early. If you want your child to learn piano and other musical instruments, you can go to the hospital for refractive examination before learning to see if your child is prone to myopia. For children who are already learning the piano, in addition to regularly checking their eyesight, parents should also pay attention to the adjustment of the background light when their children practice the piano, enlarge the staff, and give their eyes a proper rest during practice.

countermeasures:

do not learn piano under the age of 5; Copy and enlarge the score to matt paper, light yellow or light green; Put a non frequency flashing eye protection lamp for children on the piano; Rest for more than ten minutes every 45 minutes, cooperate with eye exercises or overlook and close your eyes; Take children to do more outdoor sports. The fourth killer of

: psychological factors

and

do not seem to match the decline of vision, but a data at hand shows that it is not so. According to the observer, psychologists and ophthalmologists conducted a sample survey of 4000 young people with myopia. The results show that the general decline of young people’s vision is closely related to their psychological factors.

and

are coincidental. Psychologists and ophthalmologists in China also have such a research report. Through analysis, scientists have found that there are roughly three types of vision loss caused by bad psychological factors:

and

. 1. Conditional type: this type is more common in women. In order to reduce psychological pressure while their vision decreases, Seek the sympathy and understanding of parents and teachers, often under the pretext of “blind eyes” to avoid heavy learning tasks. Most of them are afraid of learning. They often look at things in the dark, resulting in a decline in their eyesight, and then often use this to avoid learning. This kind of visually impaired teenagers even have a series of characteristics, such as refusing to attend class, headache, vomiting, nail biting and so on.

2. Glasses type:
