What to eat to prevent children's myopia

1. Food containing calcium: medical experts point out that the lack of calcium is one of the important reasons for poor visual development and even myopia. Research shows that: the eyeball is like a small plastic bag filled with water, if the lack of calcium, its hydraulic pressure will fluctuate high and low, can not maintain normal state, this situation is like a light bulb is on, it is easy to be high and low voltage burn out. If the lack of calcium eyeball, can make abnormal development and the formation of myopia.

2. Chromium: the role of chromium in the development of the eyeball is to keep its osmotic pressure in balance, otherwise it may cause the lens bulge and become convex, which will increase the diopter of the eye and become myopia. According to expert estimates, children need about 50-200 micrograms of chromium per day.

3. Hard food is often given to children to eat food with a certain hardness, which can increase the frequency and strength of the mouth, and promote the development of children's vision. Professor Chuanyue of Japan has done a special investigation for this, and the results show that children who often eat soft food such as noodles seldom use the masseter muscle of the chin, which is an important cause of abnormal vision. A study conducted by associate professor Shimada of the Department of health, medical college, Akita University, Japan, shows that among students who often eat soft food without hard work, the number of students with poor eyesight is particularly high; while those who often eat hard food, the number of students with poor eyesight is very small. This is because the mouth hard can increase the strength of facial muscles, including the eye muscle, so that it has a strong ability to adjust the lens, to avoid the occurrence of myopia.
