The sudden outbreak of the epidemic has disrupted the pace of our new semester, and the opening of primary and secondary schools and kindergartens in the city has been suspended, and children have started online learning at home. During the special period, some parents began to worry about their children's vision problems: staying at home every day, rarely going out to participate in outdoor activities, often in close contact with mobile phones, tablets, televisions and other electronic products, will the child's vision be affected? Is there a way to protect your eyesight and prevent myopia?

Let's get into the home eye care class
Let's learn scientific eye protection,
A small trick to prevent and control myopia
I believe you will definitely have a harvest!
1
Product selection
Electronics are definitely used in online learning. When possible, we try to choose electronic products with larger screens. If the TV can, the TV is preferred, followed by desktop computers, again laptops, iPads and mobile phones are best used sparingly. When using, we can adjust the screen brightness to a more comfortable state, not too dazzling. The distance between the child and the screen can be far or not near, if there is a large computer screen in the family, then the child can be 1-2 meters away from the class.

Environmental arrangement
The online learning environment is also not negligible. We are indoors, pay attention to temperature and humidity, generally indoor 18 degrees is appropriate, some families turn on air conditioning or floor heating, then it is recommended to put a basin of water, some green plants, conditional can also use humidifiers. Indoor light should also be sufficient, you can use the natural sunlight in front of the window, such as rainy days, you can turn on the lights, enhance the indoor light, to prevent eye fatigue.

Scientific sitting
Generally speaking, an online lesson lasts about 20-30 minutes. Parents should tell their children that science in class is "one foot and one punch and one inch", and some children like to lie down and read, lie down, and even cross their legs, which are very bad habits. Especially when writing homework, at the beginning the child sat very upright, but after writing for a while, he bent his back and lowered his head, and parents had to remind their children every time: "Raise your head a little, straighten your back." "In fact, this is a very passive way of education. "China Family Education News Family Education Weekly" Teacher Yang Yongmei gave us a very good suggestion, as long as a small sandbag, you can make the child passive to active, help the child develop a scientific sitting posture.

With eye care
Students are more concentrated when looking at the computer, so there are often cases of forgetting to blink, studies have shown that watching the computer blink 6-8 times a minute, less than half of the normal blink, so that it is easy to affect the tears on the eye surface, easy to dry. After a class, parents can open the window, let the child look away for 5-10 minutes, this time parents can communicate with the child, see what visual targets are 6 meters away, for example, the words on the building in the distance, count how many cars there are on the road, look at green plants, etc. Finally, let the child practice blinking about 20 times a minute, rotate the eyeballs up and down, do eye exercises, and relax the eyes.
At the end of the day, the eyes need to rest, and we can use a hot towel to give our child a hot compress to the eyes every night. In addition, parents should also prepare some foods containing vitamin A for their children, such as: carrots, cabbage, milk, nuts, vitamin A can alleviate the symptoms of dry eyes and eye fatigue.

Outdoor activities
The most effective way to prevent and control myopia is "outdoor activities", that is, to soak up the sun and enjoy the gifts from nature. Everyone knows that primary and secondary school students need to "outdoor activities" for 2 hours a day, 14 hours a week, outdoor activities can significantly reduce the incidence of myopia in children and adolescents. Even if we can't go out during the epidemic, we should open our windows as much as possible to enjoy the sun, or accept natural light on our balconies and yards. It is also in such an extraordinary period that it is rare to have the opportunity to sit around as a family and play some interesting family games, which not only enjoys the warm family time, but also plays a role in preventing myopia!

Be a good example
Finally, I would like to remind parents to put their children's physical and mental health first, cherish precious holidays, not overly exert pressure, scientifically and moderately arrange their children's learning, life and exercise, and ensure that their children sleep for 10 hours. Parents should also lead by example, control their time using mobile phones and the Internet, and play a good role model.
Tips:
To protect children's vision, parents need to do the following:
1. Adhere to good eye habits and a healthy lifestyle.
2, in front of the child as little as possible to use the mobile phone, to the child to set an example!
3. Urge children to maintain the correct posture when reading and writing with their eyes, and adhere to good eye habits.
