Juvenile visual impairment has become a common phenomenon, and it has a significant impact on the physical, mental, and health of adolescents. Nowadays, the vision of adolescents has become an important topic of special concern to society and families. However, it is common to attribute the cause of visual impairment to eye habits or poor hygiene. What is the real cause of visual impairment in children? Next, let's introduce the real culprits of adolescent vision loss.
Genetic factors
Myopia may become highly myopic if not treated in a timely manner. The factors that cause myopia in children are both parents who are highly myopic, and 100% of their children are highly myopic; If one parent is highly myopic, 50% of the children are highly myopic.
Experts and scholars have tried to identify the role of congenital inheritance in myopia; We collected 187 pairs of identical and fraternal twins and calculated their heritability based on the refractive index, axial length, and corneal curvature of both eyes. The research results show that if the heritability is 1, it means that the baby's vision is completely controlled by genetics, while 0 means that the baby's vision is not related to genetics. Statistics also found that the heritability of these twins' vision fell between 0.2 and 0.3, indicating that 20 to 30% of their vision was affected by genetic factors, while 70 to 80% was related to the acquired environment.
Dietary factors
1. A partial and selective diet leads to myopia. Some parents don't even know that eating is related to eye love. Some children are often partial or picky eaters, resulting in insufficient nutrition for eye growth, which is one of the reasons for myopia.
Therefore, experts caution that in order to prevent myopia, parents should pay attention to the food hygiene of their children, avoid making them partial or picky eaters, and diversify their diets to ensure that their children receive various nutrients necessary for the growth and maintenance of their eyes. For children suffering from myopia, dietary therapy can also be used as an adjunct. If you want to eat less sour and sweet foods, because too much sugar can produce a large amount of acid in the blood, and acidic foods can also produce a large amount of acid, which can affect the absorption of calcium ions in the food, which has a certain impact on the occurrence and development of myopia. In addition, let children eat more foods that strengthen the spleen, stomach, and qi and blood, such as longan meat, yams, carrots, yams, taro, spinach, millet, corn, and so on. You can also eat more foods such as mulberry, black beans, red dates, and walnut kernels, which can nourish the heart, calm the nerves, and brighten the eyes. It is also necessary to supplement protein, calcium, phosphorus, vitamins, etc. It is also important to supplement elements such as zinc and chromium. Soybeans, almonds, seaweed, kelp, lamb, yellow croaker, and milk powder contain high levels of zinc; Beef, grains, meat, liver, and other items are also rich in chromium.
2. Insufficient mineral elements: Medical research has shown that mineral elements such as calcium and chromium are an important condition for ensuring normal vision in children. Calcium plays an irreplaceable role in maintaining normal pressure in the eye lens, and chromium plays an irreplaceable role in maintaining refractive power in the eyes. In particular, it should be noted that over processed rice and noodles can lose 80% of the chromium element. Eating some coarse grains intentionally is beneficial to eyesight health.
3. Eating too much sweet food: Sweet food is an acidic food that consumes a large amount of calcium in the body. On the other hand, it increases blood sugar and changes crystal osmotic pressure, which is another cause of myopia. It is better to supervise children to eat less.
4. Barbecue food affects eyesight. Scientific experiments have proven that during the frying process of egg meat, many biologically active decomposition products such as oxides are produced, which have significant cytotoxic effects. An authoritative research result in the United States shows that eating too much protein food, such as Mutton shashlik and grilled fish kebabs, will cause calcium deficiency in the body. The formation of myopia is related to the lack of trace elements such as calcium and chromium in the body. In the long run, it will seriously affect the eyesight of teenagers, leading to myopia.
