Abstract: 10-13 years old is the peak of myopia. If children in this age group do not get enough sleep, their sympathetic and parasympathetic functions will lose balance, resulting in disorder in the regulation of the ciliary muscle. Therefore, it can protect their eyesight by ensuring that they get enough sleep for 9-11 hours every night., When it comes to the problem of children’s vision loss, people understand that what they do more is to use their eyes unsanitary, such as improper reading distance, too long eye use time, too strong or too dark light, and so on. In addition to the above reasons, what other factors can cause children’s vision loss?, Mineral elements are insufficient. Mineral elements such as calcium and chromium are an important condition to ensure normal vision of children. Calcium plays an irreplaceable role in maintaining normal crystal pressure and chromium plays an important role in poor eye diopter. In particular, it should be noted that 80% of chromium will be lost if the rice and flour are processed too fine. Eating more coarse food will be good for your eyesight., Eat too many sweets. Sweets are acidic food. On the one hand, they consume a lot of calcium in the body, and on the other hand, they raise blood pressure. Changing crystal osmotic pressure is another curse of myopia. It is better to supervise children to eat less., Passive smoking, tobacco contains a highly toxic cyanide, which accumulates in the human body to a certain extent and can cause toxic amblyopia. Children’s eyeballs are in the development stage and are more sensitive to the harmful substances in tobacco., Lack of sleep,
mentioned the problem of children’s vision decline. People understand that what they do more is to use their eyes unsanitary, such as improper reading distance, too long eye use time, too strong or too dark light, and so on.

mineral elements are insufficient.
calcium, chromium and other mineral elements are an important condition to ensure normal vision of children. Calcium plays an irreplaceable role in maintaining normal crystal pressure and chromium plays an important role in poor eye diopter. In particular, it should be noted that 80% of chromium will be lost if the rice and flour are processed too fine. Eating more coarse food will be good for eyesight. Too many

sweets. The
and
sweets are acidic foods. On the one hand, they consume a lot of calcium in the body, and on the other hand, they raise blood pressure. Changing crystal osmotic pressure is another curse of myopia. It is better to supervise children to eat less.
passive smoking
tobacco contains a highly toxic cyanide, which accumulates in the human body to a certain extent and can cause toxic amblyopia. The child’s eyeball is in the development stage and is more sensitive to the harmful substances in tobacco.
lack of sleep
10-13 years old is the peak of myopia. If children of this age do not get enough sleep, their sympathetic and parasympathetic functions will lose balance, resulting in disorder in the regulation of ciliary muscles. Therefore, it can protect their eyesight by ensuring that they sleep for 9-11 hours every night.
and
electronic games, tablets and televisions
and
electronic products have penetrated the field of children and have a great impact on vision. The flickering pictures on the fluorescent screen increase the burden on the eyes. The stimulation of strong light and weak light forces the ciliary muscle to be highly tense, makes the lens flex excessively and increases the diopter. Over time, it will lead to the spasm of crystalline muscle, which is also a major reason for the decline of vision.
noise
when the sound intensity is above 90 dB, the sensitivity of rod cells in fundus retina to distinguish light brightness begins to decline, and the time to recognize weak light response begins to prolong. When it exceeds 45 dB, 40% of people’s pupils dilate, and when it reaches 115 dB, the adaptability of eyes to light brightness decreases by 20%. At the same time, it is accompanied by the weakening of color perception. Therefore, parents should give a growth environment without noise pollution to avoid damage to children’s eyesight.
diseases
children who have suffered from measles, pertussis and other diseases mostly have eye enlargement. When the eye is in the expanded state, the diopter of the eye decreases and the vision decreases. Parents should find out in time and treat accordingly.
