The reason for the sharp increase of myopia is closely related to the wide use of "four machines" (TV, game, computer, mobile phone) among teenagers. At the same time, the youth diet nutrition imbalance, love to eat sweets and other habits are also one of the causes of myopia.
Each kind of dessert, has the infinite temptation to the child. This may be a common reason for most parents to refuse their children, but in fact, eating a lot of sweets will also contribute to myopia.
When sugar in sweets is metabolized in the human body, it needs a lot of vitamin B1 to help and reduce the content of calcium in the body. Vitamin B1 has a maintenance effect on the optic nerve, and its content will affect the state of the optic nerve. Calcium is the 'protector' of the eye tissue. The lack of calcium in the body will not only cause the retina elasticity to decline, the pressure in the crystal body will rise, and the anterior and posterior diameter of the eyeball will be lengthened, and the corneal ciliary muscle will have degenerative diseases, which will weaken the elasticity of the eye wall and promote myopia.
To prevent or avoid myopia deepening, the first thing is to help children develop good eating habits. Before the age of 1, do not add any sugar to your baby's food; after 1 year old, you can eat some low sugar yogurt and biscuits. Chocolate food can only be eaten after 3 years old. According to the "Chinese children and adolescents snack consumption guide", the frequency of eating chocolate should be 1-2 times a week, one small piece each time, and try to choose the dark chocolate with cocoa butter content of more than 50%. Like a variety of honey food, if preserved, plum, jujube, etc., not recommended for children to eat.
In summer, children should drink more traditional Chinese tea drinks instead of high sugar drinks, such as wolfberry chrysanthemum tea, barley tea, etc., which can not only quench thirst and heat, but also clear eyes and eliminate fire. Eat foods rich in vitamins and calcium. In addition, people have six extraocular muscles, and chewing is of great benefit to the development of the whole orbit, especially to the development of the eye muscles. At the same time of chewing, the extraocular muscles are in a state of continuous movement, which can be fully exercised. Therefore, chewing is a very good eye exercise.
