Children’s myopia in addition to overuse, the reason you can never think of!

Abstract: 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. Before

, some readers left a message on the background: my father and I are not short-sighted, my children don’t have mobile phones, and they don’t watch much TV. Why are 10-year-old children short-sighted to 6 or 7 Baidu? I don’t know why…

primary one simply replied on the background, but felt a little hasty, and it must be more than one or two parents who have such doubts, So primary one specially prepared this article, hoping to help parents!

in the past, out of curiosity, we often stole our parents’ glasses and pretended to be an intellectual. 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. What is the reason why our children put on glasses too early? How to teach them to protect their eyes?

causes of myopia

1. 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. Lack of calcium in the body will not only reduce the elasticity of the eye retina and increase the pressure in the crystalline body The lengthening 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.

and

countermeasures: eat less or no sweets and drink more milk. Milk can supplement calcium, which naturally increases the protection ability of eye tissue.

2 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

and

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 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.

3 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.

and

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.

and

countermeasures: for children learning piano, in addition to regularly checking their eyesight, parents should also pay attention to amplifying the piano score to sub light 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. Of course, in order to protect their eyesight, children under the age of 5 had better not learn the piano.

4 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.

and

countermeasures: appropriately reduce children’s learning pressure and ensure adequate sleep. Urge children to form the habit of taking a nap and reduce their pressure.

and once teenagers suffer from myopia, whether wearing glasses or not, the degree of myopia will increase with age, physical development and other reasons.

five eye care foods

and

different eye tissues need different nutrients. Only by ensuring the intake of rich protein, sufficient vitamin A, sufficient vitamin C, sufficient vitamin B and sufficient calcium can they meet their nutritional needs.

1 vitamin a

vitamin A can also prevent and treat dry eye disease. Source of

and

: it is the liver, cod liver oil, milk and eggs of various animals. The carotene contained in plant foods can be converted into vitamin A in the body, such as carrots, amaranth, spinach, leek, green pepper, sweet potato and oranges, apricots and persimmons in fruits.

2 vitamin B group

vitamin B group deficiency will lead to eye photophobia, tears, burning pain and itching, visual fatigue and eye spasm.

source: whole grains, liver, yeast, yogurt, wheat germ, beans, milk (vitamin B2), meat (vitamin B1, niacin).

3 is rich in vitamin C

if you lack vitamin C, you are prone to cataract. Source of

and

: fresh vegetables and fruits, especially green pepper, cucumber, cauliflower, Chinese cabbage, fresh jujube, pear and orange.

4 proteins

proteins are the main components of cells, and the eyes are no exception. The repair and renewal of tissues need to constantly supplement proteins. Source of

and

: lean meat, animal viscera, fish, shrimp, milk, eggs, beans and other foods are rich in protein, and protein is the main component of cells. Eyes are no exception. Protein needs to be continuously supplemented for tissue repair and renewal.

5 calcium

calcium can eliminate eye tension.

source: beans, green leafy vegetables, shrimp skin and milk are rich in calcium. Cooking methods such as spareribs soup and sweet and sour spareribs can increase the content of calciumQuantity. Make sure your baby drinks 2 cups of milk every day to ensure calcium intake.
