Abstract: as we all know, 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., One: eat sweets. Children who like to eat sweet snacks and drink soft drinks are more likely to have myopia, and drinking more milk can delay myopia. Yang Qiuyan, a pediatric ophthalmologist at Nanchang Aier ophthalmology 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 eye retina, increase the pressure in crystalline body and lengthen the anterior and posterior diameter of eyeball, It can also cause degenerative lesions of cornea and ciliary muscle, so as to weaken the elasticity of eye wall and deepen 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 “protective ability” of eye tissue., II. Noise. We all know 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. Medical research has found that when noise acts on auditory organs, it will also “spread” to visual organs through the action of nervous system, weakening people’s vision. In short, noise can reduce the sensitivity of human eyes to brightness. 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 it exceeds 45 dB, 40% of people have dilated pupils, and when it reaches 115 dB, the adaptability of eyes to light brightness decreases by 20%, accompanied by the weakening of color perception. 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., Three: psychological factors. Psychologists and ophthalmologists in China have such a research report. Through analysis, there are roughly three types of vision loss caused by bad psychological factors: ① qualified type: this type is more common in women. In order to reduce the psychological pressure and seek the sympathy and understanding of their parents and teachers, they often use the excuse of “unable to see clearly”, 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. ② Glasses desire type: their psychological visual impairment is usually manifested as: they don’t say it in their mouth, but they want to wear glasses in their heart, so they often express “poor eyesight” in front of people, which is mainly due to the worship of film and television stars wearing glasses and beautiful or scholar demeanor in “glasses advertising”. Therefore, they often wear other people’s glasses instead of myopia. Over time, they slowly develop into myopia. ③ Tension type: it shows that some teenagers have slight myopia. When they wear glasses, they can completely avoid the continuous decline of vision, but they are afraid to wear glasses. They are afraid when they mention wearing glasses. They are nervous when they think of wearing glasses. Therefore, he refused to wear glasses for a long time or secretly took off his glasses, resulting in decreased vision. Countermeasures: children are actually the most observant diplomats. Parents should try their best to restrain their emotions in front of children and don’t make children feel uneasy; Interact with children more, pay attention to children’s mental health, overcome bad mentality and keep children in a positive and good mood., After reading the above reasons, are you stunned? It turns out that eating more sugar will lead to myopia, the tweeter of the downstairs square dance will lead to myopia, and the baby will also be myopia if he is unhappy… Of course, mothers don’t have to be too anxious. With the help of scientific prevention and control measures, myopia can be prevented and controlled.,
