Abstract: children often like to stare at TV and computer to watch cartoons and other programs, and this is an afternoon or a night, which is very easy to cause eye fatigue and damage their eyesight. Or playing with mobile phones or computers for a long time, and your eyes are unknowingly damaged., In the past, out of curiosity, children often stole their father’s glasses and pretended to be an intellectual like a “little adult”. Now, more and more children don’t have to steal their parents’ glasses because they have their own glasses., Myopia is getting younger and younger, so what is the reason for our children to wear glasses too early? Don’t worry, let’s look down: 1. If you spend too much time with your eyes, children often like to stare at TV and computer to watch cartoons and other programs, and this view is one afternoon or one night, which is very easy to cause eye fatigue and damage your eyesight. Or playing with mobile phones or computers for a long time, and your eyes are unknowingly damaged., Countermeasures: when watching TV or electronic products, set a good time, preferably not more than an hour, pay attention to rest and relax your eyes., 2. 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. The lack of calcium in the body will not only reduce the elasticity of the eye retina, increase the pressure in the crystal body, elongate the anterior and posterior diameter of the eye, but also cause degenerative diseases of the cornea and ciliary muscles, Thus, the elasticity of the eye wall is weakened and myopia is deepened., Countermeasures: eat less or no sweets and drink more milk. Milk can supplement calcium, which naturally increases the “protective ability” of eye tissue.,
in the past, children often stole their father’s glasses out of curiosity and pretended to be an intellectual, like a “little adult”. Now, more and more children don’t have to steal their parents’ glasses because they have their own glasses.
myopia is getting younger and younger, so what is the reason for our children to wear glasses prematurely? Don’t worry, let’s look down:
1 use your eyes for too long
children often like to stare at TV and computer to watch cartoons and other programs, and this is one afternoon or one night, which is very easy to cause eye fatigue and damage their eyesight. Or play with mobile phones or computers for a long time, and your eyes are unknowingly damaged.
and
countermeasures: set a time when watching TV or electronic products, preferably no more than one hour, pay attention to rest and relax your eyes.
2 sweets
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. The 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, but also make cornea The ciliary muscle has degenerative lesions, which weakens the elasticity of the eye wall and contributes to the deepening of myopia.
and
countermeasures: eat less or no sweets and drink more milk. Milk can supplement calcium, which naturally increases the “protection ability” of eye tissue.
3 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.
countermeasures: try to reduce the volume when using household appliances or talking.
4 psychological factors
bad psychological factors lead to vision loss. There are roughly three types:
1. Qualified type: this type is more common in girls. They often use the excuse 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 use it to avoid learning.
2. Glasses desire type: This is mainly due to the worship of film and television stars wearing glasses and beautiful or scholar style 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 nervous at the thought of wearing glasses. Therefore, he refused to wear glasses for a long time or secretly took off his glasses, resulting in decreased vision.
and
countermeasures: parents and teachers should interact with their children more, pay attention to their children’s mental health, help their children overcome their bad mentality and keep their children in a positive and good mood.
5 family environment
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.
and
countermeasures: children are actually the most observant diplomats. Parents should try to restrain their emotions in front of their children and don’t make them feel uneasy. And more communication with children, so that children have a healthy body and mood.
6 living environment
the environment that many children can’t change unknowingly hurts their eyes. 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.
and
countermeasures: try to create a bright and spacious learning environment for children and avoid children using their eyes too much in too bright or too dark places.
