Children’s myopia is not only because of TV, some factors startle you!

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

when it comes to myopia, it is something that parents strictly guard against and absolutely don’t want to happen to their children.

and

but there are still more and more small glasses around. What is the reason?

and

have many new statements recently: the causes of myopia are not only unsanitary use of eyes, but also many wonderful reasons you can’t think of! Don’t say don’t know, the world is really wonderful, let Xiaobian tell you the same!

and

dessert killers – a

and

survey found that children who like to eat sweet snacks and drink soft drinks are more likely to be myopia, and drinking more milk can delay myopia. The metabolism of sugar in

and

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 eye retina, increase the pressure in lens and lengthen the anterior and posterior diameter of eyeball, but also cause degenerative diseases of cornea and ciliary muscle, Thus, the elasticity of the eye wall is weakened and myopia is deepened.

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.

and

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

noise Killer 2

we all believe 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.

and

studies show that when the sound intensity is above 90 dB, the sensitivity of rod cells in the fundus retina to distinguish light brightness begins to decline, and the time to recognize weak light response is prolonged. When the sound intensity exceeds 45 dB, 40% of people have dilated pupils, and when it reaches 115 dB, the adaptability of the eyes to light brightness decreases by 20%, accompanied by the weakening of color perception.

and

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.

and

learn piano too early. The third killer

and

are known as the king of musical instruments. They 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, if you want children to learn piano and other musical instruments, you can go to the hospital for refractive examination before learning to see if children are likely to be short-sighted. 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.

and

countermeasures: it is not appropriate to let children learn piano too early; 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.

and

psychological factors killer four

and

psychological factors seem to be out of touch with vision loss, but a data at hand shows that it is not so. Psychologists and ophthalmologists conducted a sample survey of 4000 adolescent myopia patients. The results show that the general decline of adolescent vision is closely related to adolescent 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 refuse to attend class, headache, vomiting, nail biting and a series of special symptoms
