Abstract: lack of nutrition: many children and adolescents are picky and partial eaters. They eat less or don’t eat vegetables, fruits, bean products, coarse grains and other foods. This habit can lead to the lack of vitamin A, vitamin B1, vitamin B12, vitamin C, vitamin E, vitamin D, chromium, calcium, zinc and other elements in their bodies, so they are prone to pseudomyopia;
now some children have a partial eclipse phenomenon, but parents are afraid that their children will be wronged and do not correct it in time, so that their children gradually form bad eating habits, resulting in the increasing lack of calcium and chromium in their bodies. In addition, teenagers and children like to eat too much carbohydrates and high carbohydrate foods, which also reduces the elasticity of intraocular tissue, the continuous reduction of trace elements in the body, and the eye axis is very easy to grow. Moreover, excessive consumption of sugar will continuously increase the blood glucose content, which will cause changes in the osmotic pressure of aqueous humor and lens. When the osmotic pressure of aqueous humor is lower than that in the crystalline body, it will promote the convex lens and lead to myopia.
from a medical point of view, myopia is divided into true and false. To distinguish true and false myopia, in addition to optometry in the hospital, parents can use a simple method to test their children’s eyesight at home. Hang an international standard eyesight chart at a distance of 5 meters, first determine their eyesight, then wear 300 degree presbyopic glasses and look into the distance. A cloud like scene will slowly appear in front of them. Take off their glasses half an hour later, and then check their eyesight. If their eyesight is enhanced, It can be considered as pseudomyopia; If your eyesight is still or decreased, you can do it once a day and repeat it for three consecutive days. If your eyesight is still not improved, it can be determined as true myopia.
the causes of pseudomyopia are:
1. Unscientific eye use for a long time, such as long-term reading or using electronic products;
2. Lack of nutrition: many children and adolescents are picky and partial eaters. They eat less or do not eat vegetables, fruits, bean products, coarse grains and other foods. This habit can lead to the lack of vitamin A, vitamin B1, vitamin B12, vitamin C, vitamin E and vitamin D, as well as chromium, calcium, zinc and other elements in their bodies, so they are prone to pseudomyopia;
3. The treatment of ametropic amblyopia is not timely. Teenagers and children can seize the time during the rest period after the examination, actively adjust from the aspects of food therapy and eye hygiene, and their eyesight can also be improved in a short time. If pseudomyopia is not relieved in time, it is easy to become true myopia.
therefore, teenagers and children should develop scientific eating habits, pay attention to nutrition, eat more coarse cereals, eat less candy and foods with high content, limit the intake of high animal fat, reduce the excretion of chromium and calcium in the body, and maintain the continuous and stable state of chromium and calcium in the body.
