Eat these foods regularly and your child will never become nearsighted

Children are a high-risk group for myopia, which has a lot to do with their physiological characteristics and their way of life and learning. Therefore, prevention of myopia must start from childhood. In order to prevent children from wearing glasses too early, how should we provide them with rich protein and vitamins? And what foods can prevent myopia?

1. Hard Food

Regularly feeding children food with a certain degree of hardness can increase the frequency and strength of chewing and promote the development of children's vision. A Japanese professor named Funakoshi conducted a special investigation on this. The data showed that children who often eat soft food such as thin noodles rarely use the masseter muscles in the jaw, which is an important cause of abnormal vision. A study shows that among students who often eat soft food that does not require much chewing, there are many who have poor eyesight, while among those who often eat hard food, there are very few who have poor eyesight. This is because chewing hard can increase the strength of facial muscles including eye muscles, giving them a strong ability to adjust the lens and avoid the occurrence of myopia.

Hard foods that are more suitable for children include: carrots, fruits, cabbage, animal bones, beans, etc. These foods are both durable and nutritious, and are particularly worth recommending.

2. Calcium-containing foods

Calcium is a mineral element that we are relatively familiar with and that we attach great importance to, but people's understanding of it is still focused on promoting bone development and preventing rickets in children, and rarely associate it with eye development. However, medical experts point out that calcium deficiency is one of the important reasons for poor visual development and even the formation of myopia. The scientific basis for this is: the eyeball is like a small plastic bag filled with water. If there is a lack of calcium, its "hydraulic pressure" will fluctuate and cannot maintain a normal state. This situation is like a lit light bulb, which can easily be burned out by the fluctuating voltage. If the eyeball lacks calcium, it may cause developmental abnormalities and lead to myopia.

Calcium-containing foods include: milk, soy products, fish, shrimp, animal bones, etc. Also pay attention to pairing them with foods rich in vitamin D such as animal liver, egg yolks, green vegetables, etc. to increase calcium absorption and utilization.

3. Foods containing chromium

Chromium is also an essential mineral element for the human body. Its role in the development of the eyeball is to maintain the balance of its osmotic pressure. Otherwise, it may cause the lens to bulge and become convex, resulting in an increase in the eye's refractive power and myopia. According to experts' estimates, children need about 50-200 micrograms of chromium per day.

Foods containing chromium include: cereals, meat, cheese and egg yolks, etc., which should be given more to children.

Methods for preventing myopia in children

When studying, pay attention to choosing listening instead of reading to reduce the load on the eyes when looking at close objects. Every day, I insist on looking into the distance, doing eye exercises and physical exercises during breaks, and actively participate in cultural and sports activities.

There should be sufficient light when studying, and the light should come from the left side. Avoid reading or writing in insufficient light, glaring sunlight or strong light.

Do not sleep in bed or read while walking. Don't lean over the table with your head tilted to one side to read or write.

Don't watch TV too many times or for too long, it should be kept within 1 hour. Don't get too close. At least two meters apart.

Avoid looking at close objects for too long. Note that you should take a break after reading, writing, operating a computer, etc. after 40 minutes of continuous close viewing, and look into the distance for 10-15 minutes. Try to control the total time you spend looking at nearby objects every day, preferably not more than 6 hours.

Correct bad near-sightedness. When reading and operating a computer, be sure to keep the distance between your eyes and the book at about 33 cm. The distance between your eyes and a 35 cm computer screen should not be less than 60 cm, and the distance between your eyes and a 38 cm computer screen should not be less than 70 cm. The posture should be correct. Do not read while lying down or walking.

The classroom lighting should be bright, the desks and blackboards should not be too reflective, and seats should be changed regularly.
