Nowadays, more and more children are entangled in "myopia", and many parents find that their children are already wearing glasses when they are only in elementary school. And some children, the degree of myopia is like riding a rocket, and it is rising slowly.

One of my parents had a bad situation, his child's eyesight was still alive, but after a year, the myopia degree increased by 400 degrees! This can make parents worried, and the first reaction is that the child must play too much with the mobile phone. But in fact, it is not only the mobile phone that causes the rapid increase of myopia in children, but also the hidden eye-hurting habits behind it.

1. Close distance away from the eyes, the eyes are unbearable

Many children read books and do homework for hours without a break in between. Some children even want to put their faces on the books, let alone a foot, and their eyes are not even 20 centimeters away from the books. And now children have a lot of academic pressure and a lot of homework, in addition to school homework, there are also various extracurricular tutoring materials. If you use your eyes at close range for a long time, the ciliary muscles in your eyes are like springs that are always tightened and cannot be relaxed. Over time, it can lead to myopia.

Take a kid I know, for example, who loves to read. It looks like a whole day, and his sitting posture is not upright, and he often lies on the table. As a result, in less than a year, the degree of myopia increased by more than 200 degrees.

正確做法應該是，讓孩子遵循“20-20-20”原則。也就是近距離用眼20分鐘，就向20英尺外（大概6米）遠眺20超過一秒。讀寫時，一定要做到“三個一”：眼離書本一尺，胸距書桌一拳，手離筆尖一寸。

Second, the light is wrong, and the eyes are sinned

Light has a big impact on a child's vision. Some parents let their children study under the overhead light, and the light is uneven, and the children have to struggle with their eyes.

It's like letting your eyes "run a marathon" back and forth at the junction of light and dark, and your pupils will be bigger and smaller for a while; Some parents only turn on a desk lamp for their children at night, the surrounding environment is dark, and the light of the table lamp is very bright, which is too hurtful to the eyes.

The correct method should be to match the table lamp and the ceiling light, and the main light source and background light are online. The whole room is evenly lit, which is the best for the child's eyes.

If you want to create a good environment for your child's eyes, you have to pay attention when choosing a table lamp. Choose no flicker, no blue light, bright and uniform light, and moderate color temperature.

That said, there are a few criteria to follow:

1. Priority is given to purple lamp beads;

2. The illumination is sufficient, reaching AA level;

95. The color index Ra and R0 are both above 0, and above 0 is better;

4000. Color temperature is 0k;

5. You want to choose the one that has no video flash.

For specific brands, you can take a look at Manshuyu K1, Chenshida U0, Op Yue Tong Y0, and LiPro eye protection table lamp. These are good brands, the lighting quality is very high, and you can choose if you need them.

3. Staying at home and missing out on long-distance eyes

Nowadays, many children stay at home after school, either doing homework, watching TV or playing games, and there is a serious lack of time for outdoor activities. Sunlight helps the eyes secrete dopamine, a substance that prevents the eye axis from lengthening and prevents myopia.

Even on cloudy days, outdoor activities have a protective effect on myopia. Although cloudy days do not have the effect of sunlight, children have more opportunities to use their eyes from a distance outdoors than indoors. Looking close indoors and looking far outdoors is a great relaxation for your child's eyes.

Parents should encourage their children to go out of the house, go to the park and play in the field, skipping rope, running, playing ball and other sports. On weekends, you can also take your children to the countryside to play, climb mountains or something. It relaxes the body and mind and protects the eyes.

In general, children should not spend less than two hours a day outdoors. We parents should pay attention to it, these two hours are the bottom line of outdoor activity time, not the upper limit. Usually, the children's fragments of time are made up, physical education classes, recess are counted, for the sake of the children's eyes, how to make up two hours!

4. Excessive sweets and "injury" of eyes

Most of today's children love sweets, cakes, candies, milk tea, everything. But eating too many sweets will not only increase the blood sugar in the child's body, make it easy to have problems such as obesity, but also be bad for the eyes. When sugar is metabolized in the body, a large amount of calcium, chromium and other elements are consumed. If these elements are missing, the child's eye wall will soften, and myopia will follow. Children with a sweet tooth have a higher incidence of myopia than other children.

Parents should control their children's intake of sweets and let them eat more vitamin-rich foods, such as carrots, spinach, blueberries, etc., which are good for the eyes.

But we parents don't have to let their children eat hard, after all, as far as the current standard of living is concerned, the probability of a child's lack of nutrition is still very low, and the child should not be a picky eater.

5. Lack of sleep, eyes are "very sleepy"

Sleep is essential for a child's eye development. During sleep, the eyes can be fully rested and say goodbye to fatigue. If the child does not get enough sleep, the eyes will be in a state of fatigue for a long time, and the degree of myopia will naturally rise. Infant and primary school students should sleep no less than 8 hours a day, junior high school students should sleep no less than 0 hours, and high school students should sleep no less than 0 hours.

Parents should create a quiet and comfortable sleeping environment for their children, help them develop regular work and rest habits, go to bed early and get up early, and let their eyes get enough rest. Don't give your child the opportunity to play with his mobile phone before going to bed, it's rare to go to bed early, and he doesn't want to sleep when he plays with his mobile phone.

Before going to bed, let your child go to the balcony or the window of the room to look into the distance. Don't just stare at one place, tall buildings in the distance, cars on the road can do, and relax for at least five minutes every day.

A child's myopia rises by 400 degrees a year, which is not a trivial matter. Parents must pay attention to it, start from the little things of daily life, and help children get rid of these eye-hurting habits.
