Abstract: 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, they can ensure that they get enough sleep for 9-11 hours every night, which can protect their eyesight., When it comes to the topic of children’s vision loss, what people know most is that the habit of using eyes is unhealthy, such as improper reading distance, long eye use time, too strong or too dark light, and so on. In addition to the above reasons, there are also the following factors causing the decline of children’s vision: lack of mineral elements ~, medical research shows that mineral elements such as calcium and chromium are an important condition to ensure children’s normal vision. Calcium plays an irreplaceable role in maintaining the normal pressure of eye crystals, and chromium plays an irreplaceable role in maintaining eye diopter. In particular, it should be noted that 80% of chromium will be lost if the rice and flour are processed too fine. Deliberately eating some coarse grain is beneficial to the health of eyesight., Too many sweets!, Sweets are acidic foods. On the one hand, they consume a lot of calcium in the body. On the other hand, they increase blood sugar and change crystal osmotic pressure, which is another curse for the formation of myopia. It is better to supervise children to eat less., Passive smoking, German experts found that 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,
brings up the topic of children’s vision decline. What people know most is that the habit of using eyes is unhealthy, 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, the factors causing the decline of children’s vision are as follows:
mineral elements are insufficient ~
medical research shows that mineral elements such as calcium and chromium are an important condition to ensure children’s normal vision, and calcium plays an important role in maintaining the normal pressure of eye crystals, Chromium plays an irreplaceable role in maintaining eye diopter. In particular, it should be noted that processing too fine rice and noodles will lose 80% of chromium. Deliberately eating some coarse grains is beneficial to vision health.
eat too many sweets!
and
sweets are acidic foods. On the one hand, they consume a lot of calcium in the body. On the other hand, they increase blood sugar and change crystal osmotic pressure, which is another scourge leading to the formation of myopia. It is better to supervise children to eat less.
passive smoking
German experts found that 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 of the regulation function of the ciliary muscle. Therefore, they can ensure that they get enough sleep for 9-11 hours every night, which can protect their eyesight. A series of electronic products such as
and
video games, televisions, tablet
and
video game consoles have penetrated into the field of children, which has a great impact on vision. The flickering picture on the fluorescent screen increases the burden on the eyes. The stimulation of strong light and weak light forces the ciliary muscle to be highly tense, resulting in excessive flexion of the lens and increase the diopter. Over time, it can lead to ciliary muscle spasm, which is also a major reason for the decline of vision. Therefore, parents must supervise their children: a they must control the time to avoid excessive fatigue and dryness of children’s eyes. B correct the child’s bad sitting posture. C select professional visual rehabilitation institutions)
noise
the research of relevant experts shows that when the sound intensity is more than 90 dB, the sensitivity of rod cells in 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, reaching 115 dB, The adaptability of eyes to light brightness decreased by 20%, accompanied by the weakening of color perception. Therefore, parents should pay attention to the noise pollution around their children’s growth environment, give their children an environment without noise pollution, and avoid the damage of noise to their children’s eyesight.
disease
a considerable number of patients have suffered from measles, pertussis and other infectious diseases. Most of these children have eye enlargement. When the eye is in the expanded state, the refractive power of the eye decreases and the vision decreases. In terms of such diseases affecting vision, parents should find them in time and treat them accordingly.
