Abstract: calcium deficiency directly affects the sensitivity of the eyes to light. Calcium deficiency can increase the excitability of nerve and muscle cells, often in a state of tension. Excessive tension of ciliary muscle will directly compress the eyeball. When scleral tissue is calcium deficient, its elasticity and firmness will decrease, the hardness of scleral wall will weaken, and the ocular axis will prolong., Some parents will ask, I usually pay great attention to the child’s eye health, why the child is still short-sighted. Experts point out that lack of nutrition can cause children’s myopia. So, what nutrition deficiency can cause children’s myopia?, What nutrition deficiency can cause children’s myopia?, 1. Calcium deficiency directly affects the sensitivity of the eyes to light. Calcium deficiency can increase the excitability of nerve and muscle cells, often in a state of tension. Excessive tension of ciliary muscle will directly compress the eyeball. When scleral tissue is calcium deficient, its elasticity and firmness will decrease, the hardness of scleral wall will weaken, and the ocular axis will prolong., 2. Lack of protein protein is the raw material of human tissue cells, just as important as bricks, steel bars and cement used in building houses. Insufficient protein supply will affect the growth and development of teenagers, form weak physique, easy to expand, elongate the anterior and posterior axis of the eyeball, and form the refractive state of myopia., 3. Vitamin deficiency VA is an important nutrient especially needed by the eyes. VC plays a role in maintaining the integrity of scleral tissue. Without VC, scleral tissue will be affected by hyaluronidase and become very fragile. VD deficiency directly affects the normal metabolism of calcium. This is closely related to the occurrence of myopia., Lack what nutrition can cause child myopia? What are the main factors leading to children’s myopia?, Clinical research shows that dozens of factors are related to the formation of myopia, among which the most important factors are:

lack of what nutrition can cause children’s myopia?
1. Calcium deficiency directly affects the sensitivity of the eyes to light. Calcium deficiency can increase the excitability of nerve and muscle cells, often in a state of tension. Excessive tension of ciliary muscle will directly compress the eyeball. If the scleral tissue lacks calcium, the elasticity and firmness will decrease, the hardness of scleral wall will weaken, and the ocular axis will prolong.
2. Lack of protein protein is the raw material of human tissue cells, just as important as bricks, steel bars and cement used in building houses. Insufficient protein supply will affect the growth and development of teenagers, form weak physique, easy to expand, elongate the anterior and posterior axis of the eyeball, and form the refractive state of myopia.
3. Vitamin deficiency VA is an important nutrient especially needed by the eyes. VC plays a role in maintaining the integrity of scleral tissue. Without VC, scleral tissue will be affected by hyaluronidase and become very fragile. VD deficiency directly affects the normal metabolism of calcium. This is closely related to the occurrence of myopia.
lack of what nutrition can cause children’s myopia? What are the main factors leading to children’s myopia?
clinical research shows that dozens of factors are related to the formation of myopia, among which the most important factors are:
1. Children with less sleep time are prone to myopia. In the rapid growth and development period of children, especially at the age of 7-9 and 12-14, if they sleep less, they will cause myopia in some children.
2. Low birth weight. Children with a birth weight of less than 2000g are mainly due to their congenital dysplasia and acquired adverse factors, resulting in long ocular axis development, and are prone to myopia in adolescence.
3. Premature infants, especially those born 2 weeks or more prematurely, often have myopia in childhood.
4. Parents are myopic, and their children are prone to myopia, and their genetic degree increases with the deepening of myopia. Generally speaking, there is little inheritance of myopia below – 3.00d, and high myopia greater than – 6.00D is closely related to inheritance.
5. When watching TV and computer for more than 2 hours every day, the distance between eyes and TV is less than 3m, and the reading distance for a long time is less than 30cm, most children will have visual fatigue, and some of them will have myopia.
therefore, children with low birth weight, premature infants and high myopia of their parents should go to the hospital for examination as soon as possible. Usually urge children to develop good eye habits, pay attention to eye hygiene, avoid long-time and close eye use, limit the time of watching TV < half an hour / day, do not eat partial food, eat less sweets, eat more foods rich in vitamins, protein and calcium, strengthen physical exercise, enhance body quality and ensure adequate sleep. Children diagnosed with true myopia should wear glasses correctly, Check regularly to control the deepening of myopia as much as possible.
