What is the cause of myopia in three-year-old children?

Parents have always regarded their children as the most important thing in their lives. They care about and take care of their children every day. In particular, many children have no control over themselves, so they often do things that hurt their bodies, such as long-term exposure to radiation or watching TV. This makes many parents worry that their children will become myopic. So what is the cause of myopia in 3-year-old children?

Seven reasons make your eyes more and more nearsighted:

1. Too much close-up

In the city, people's line of sight is within 5 meters most of the time. You can't explain to your children what the horizon is because they can't see it at all! It is precisely because the field of vision in the city is narrow and there is a lack of environment that can provide children with a far view, so there is no need for farsightedness. Therefore, his farsightedness function will become weaker and weaker.

2. Too little time for outdoor activities

Today's living space is too small, and children spend most of their time indoors, using their eyes a lot at close range. However, children's eyes are highly adaptable and will adjust themselves to the close distance. Moreover, as you spend more time indoors, you have more opportunities to watch TV and play computer games. If you do not pay attention to the distance and posture, it is easy to cause excessive eye fatigue.

Outdoors, no matter how close an object is, it is still farther away than indoors. Studies have shown that children who often exercise outdoors are less likely to suffer from myopia than children who do not go out often.

3. Focus on indoor games

What did we play in the past? Spinning tops, throwing sandbags, hide-and-seek, rolling hoops... In short, most of them were outdoor group activities. When you are outdoors, your eyes will automatically adjust to look at objects at different distances. Alternating between near and far objects will allow the ciliary muscles of your eyes to adjust and you won't feel tired. Nowadays, for reasons of safety and convenience, parents mostly let their children play at home. Even if you make an appointment with your children to play together, either go to their house or your house, and indoor games are still the main focus. In this way, children use their eyes at close range, which puts a heavy burden on their eyes.

In today's life, many parents and friends will find that there are more and more children wearing glasses on the street. Children wear glasses not necessarily because they read too much, but because of long-term exposure to radiation, playing with mobile phones, playing computers, or watching TV may cause children's eyesight. In order to prevent children from myopia, it is recommended not to reduce children's outdoor activities. It is best to let children focus on games and stay away from the harm of TV.
