In daily life, we may still have some misunderstandings on the prevention and control of myopia, and tell you what is the secret of preventing and controlling myopia.

Eating carrots does not prevent myopia

Can eating carrots prevent myopia?

The answer is no. The biggest nutritional feature of carrot is that it is rich in carotene, of which β-carotene accounts for about 85% and α-carotene is below 15%.

It plays a variety of health-beneficial roles in the body: anti-oxidation, immune regulation, inhibiting the proliferation of cancer cells. It's true that carrots are good for your eyesight. Because the beta-carotene in carrots can be converted into vitamin A in the body, but this does not prevent myopia.

Can carbonated drinks aggravate myopia? The answer is "to the heart". Experts said that drinking carbonated drinks can not only cause a decline in physical fitness, but also cause the degree of myopia to deepen.

If you often drink carbonated drinks, the calcium in the body is reduced, resulting in a decrease in the content of calcium in the sclera, so that the eye wall loses the normal elasticity, the eyeball is easy to be elongated, so that the degree of myopia is increased too quickly.

Can nutrition balance prevent myopia degree deepening? The answer is yes. Studies have found that most short-sighted people also lack trace elements such as zinc and chromium in their bodies.

In addition, excessive consumption of sugar reduces the amount of protein 3, a growth factor in the body, which is an effective substance in inhibiting the growth of the eyes.

Teenagers should eat more animal brittle bones, beans, shrimp, eggs, peanuts, dates and other foods with high calcium content, and drink less carbonated drinks, especially cola drinks.

This will ensure the daily intake of calcium, while strengthening the body, but also slow the deepening of myopia.
