Abstract: bad eye habits have far-reaching destructive effects on the eyes. Children’s self-control ability is poor, they do not pay attention to the correct reading and writing posture, the allocation of desks and chairs is incorrect, they do not understand the importance of preventing myopia, and they do not have the awareness of being responsible for their own eyes., Speaking of myopia, it’s a thing that parents don’t want to happen to their children, but there are more and more small glasses around. What’s the reason? The causes of myopia are not only eye fatigue or unsanitary use of eyes, but also many reasons you can’t think of ↓↓↓. The metabolism of sugar in sweets, sweets and carbonated drinks in the human body requires a large amount of vitamin B1 and reduces the content of calcium in the body. Calcium is the “protector” of eye tissue, and the body lacks calcium, It will not only reduce the elasticity of the retina, increase the pressure in the crystalline body and lengthen the anterior and posterior diameter of the eyeball, but also cause degenerative lesions in the cornea and ciliary muscle, so as to weaken the elasticity of the eyeball wall and deepen myopia., Noise, when noise acts on the auditory organs, it will also “spread” to the visual organs through the action of the nervous system, weakening people’s vision. In short, noise can reduce the sensitivity of human eyes to brightness. The research of relevant experts shows 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 it 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., Learning piano too early, 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. Practicing piano too early and for a long time will accelerate the development of eyeball emmetropia and consume the original hyperopia too early. If it is not corrected in time, children are more likely to have myopia., Family factors,
talk about myopia, which is a thing that parents don’t want to happen to their children, but there are still more and more small glasses around. What’s the reason? The causes of myopia are not only eye fatigue or unsanitary use, but also many reasons you can’t think of ↓↓↓↓
sweets
sweets and carbonated drinks. The metabolism of sugar 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. Calcium is deficient in the body, It will not only reduce the elasticity of the retina, increase the pressure in the crystalline body and lengthen the anterior and posterior diameter of the eyeball, but also cause degenerative lesions of the cornea and ciliary muscle, so as to weaken the elasticity of the eyeball wall and deepen myopia.
noise
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. The research of relevant experts shows 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 identify 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 the eyes to light brightness decreases by 20%, accompanied by the weakening of color perception.
learn piano too early
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.
family factors
discord between husband and wife, tense relationship between parents and children, parents’ abuse of children, etc. will cause children’s visual impairment, which is mainly seen in preschool children and often ignored. Adult visual acuity is also related to psychology. Central retinal and choroidal disease is a common eye disease, which is seen in adults. The patient’s visual acuity can suddenly decline significantly. In daily life, there are cases of crying and blindness due to excessive sadness.
living environment
the environment that many children can’t change has hurt their eyes unknowingly. Including the uneven reflection of the classroom blackboard, the wall is too bright, the lighting is too bright or too dark, and the desk and chair are inappropriate, which will directly, silently and for a long time affect the child’s vision.
eye habits
bad eye habits have far-reaching lethality to the eyes. Children’s self-control ability is poor, they do not pay attention to the correct reading and writing posture, the allocation of desks and chairs is incorrect, they do not know enough about the importance of preventing myopia, and they do not have the awareness of being responsible for their own eyes.
lack of sleep
lack of sleep will cause children’s systemic autonomic nerve dysfunction, affect the local sympathetic and parasympathetic nerve dysfunction of the eyes, and lead to the disorder of ciliary muscle regulation, which is the pathological basis for the formation of myopia.
