Myopia grows fastest in winter. What is the reason?

Because dopamine can inhibit the growth of axial length, the sunshine time in autumn and winter is reduced, and myopia will increase more; In addition, when the weather is cold in autumn and winter, the time for outdoor activities will be reduced, and the time for using eyes at close range will be increased, leading to the rapid growth of children's myopia.

Myopia rate in winter is always in a high incidence period. Why is myopia easier in winter? Children don't have enough outdoor activities. With the cold weather in winter, most people tend to stay indoors, and there are fewer outdoor activities. In winter, I am bored at home, more addicted to electronic products, and my eye time is growing rapidly. Their eyes are in a state of close use for a long time, and the ciliary muscle overload adjustment cannot be relaxed.

Due to the lack of outdoor exercise, blood circulation will also slow down, affecting the ability of blood supply and oxygen supply to the eyes and increasing visual fatigue; In winter, the sky is dark, the days are short, the nights are long, the light is dim, and the smog is serious, which makes the already poor eyesight worse.

How to prevent myopia in winter? Ensure a certain amount of outdoor sports. If you are afraid of cold, you can insist on playing badminton or table tennis for half an hour every day. These two sports not only exercise your body, but also improve your child's visual level. You can watch the ball if you can't play. Stand on the side of a table or court and keep your head still. Only let the eyes rotate with the trajectory of the ball, which enhances muscle regulation and increases the blood supply and oxygen supply ability of the eyes.

Do eye exercises regularly to relieve visual fatigue and protect your eyesight. Don't let children watch computer, TV and books for a long time. Children should not watch TV and computer for more than two hours every day. Use electronic products for about half an hour, let children stand up and move around, look out the window, look at the green plants outside, or close their eyes for a few minutes, so that their eyes can have a short rest and relieve visual fatigue.

Keep enough light. After five o'clock in the afternoon in winter, it is already gloomy. Most children will face the problem of poor light when they go home to do their homework. It is harmful to their eyesight to rely solely on the ceiling lamp in the room. You can buy a high-quality desk lamp for your child to protect your eyesight. Let children develop good sitting habits. Reading and doing homework should adhere to three "ones": one punch from the table, one foot from the book and one inch from the pen tip.

Let children develop healthy eye habits, don't rub their eyes with dirty hands, and pay attention to eye hygiene. Protecting children's eyes is a marathon, which requires the cooperation, patience and persistence of every family to make a faithful wife achieve perfect results.
