Why do children become nearsighted? Causes of myopia in children

Nowadays, myopia has become a major disease that endangers children's health. The reason why children have myopia is mostly because they do not pay attention to the time of using their eyes, they like to eat sweets in their daily life, and they do not get enough sleep at night.

1. Not paying attention to the time spent using the eyes: Children nowadays have more opportunities to come into contact with electronic products. Many parents, who don’t want to supervise their children, give their children a mobile phone or tablet to play with. However, these products can cause great harm to the eyes. Long-term use of electronic products without paying attention to rest can easily lead to fatigue of the ciliary muscles of the eyes, resulting in myopia in children.

2. Like to eat sweets: This is also an important reason for the high incidence of myopia in children. Children nowadays like colorful candies. In addition to containing a lot of additives, the large amount of sugar intake can also cause the risk of myopia. Excessive intake of sugar will reduce the calcium content in the human body, and calcium is an important macronutrient required by the retina. Reduced calcium will lead to weakened retinal elasticity and decreased eye accommodation function, resulting in myopia in children.

3. Lack of sleep: Lack of sleep is also one of the reasons why children are prone to myopia. Children nowadays are often under great pressure to study. If they do not get enough sleep and their eyes do not get enough rest, their eyes will become easily fatigued, which may induce myopia in children.

To sum up, myopia has become an important disease that endangers children's eye health. It is particularly important for parents to understand the causes of myopia in children. This article summarizes the three main causes of myopia in children, mainly long-term use of electronic products, resulting in excessive eye strain; children who like to eat sweets are more likely to develop myopia; and insufficient sleep can also induce myopia. Therefore, parents must pay attention to the above issues to reduce the chance of myopia in children.
