What causes poor vision in children?

Many years ago, it was very rare to see people wearing glasses, but today, even elementary school students as young as a few years old have started wearing glasses. This means that in modern society, vision loss has obviously become a popular problem, mainly because there are too many electronic products and people always overuse their eyes. So the question is, many children do not face computers every day, why do they have poor eyesight?

1. Unscientific use of eyes. For children aged 1-6, scientific eye use is important. However, with the proliferation of electronic products in modern society, children can easily become addicted to iPad games, the Internet, and TV, and lack the self-control to take a proper rest. At the same time, parents have excessively high expectations for their children, requiring them to learn various talents, attend cram schools, etc., which increases the burden on their children's eyes.

2. Insufficient nutrition intake. Malnutrition and lack of certain nutrients in children can also cause vision problems. In my opinion, many children in real life often have the habit of being picky and partial in eating, which leads to insufficient intake of vitamins, calcium and other elements in the body, resulting in weakness and illness. For example, selenium is present in high concentrations in the human eye, where it can enhance visual acuity. Therefore, when a person is deficient in selenium, he or she is prone to myopia. Common foods such as beans, mushrooms, eggs and meat are high in selenium.

3. Refractive error and untimely treatment. If a child suffers from myopia, untimely treatment will often lead to worsening of myopia, amblyopia or pseudomyopia. If the best treatment period is delayed, myopia will easily occur.

4. Congenital genetic diseases. For many children in pairs 1-6, there is a greater chance of congenital cataracts and glaucoma, and newborns may also experience symptoms such as retinopathy.
