Friends who like to play with their mobile phones in bed at night, this is very useful for you!

The eyes are the windows to the soul, especially at night, when most people hide under the covers and play with their mobile phones. But you can't forget that mobile phones have radiation. Although it is small, long-term accumulation will stimulate the nervous system. Of course, if you are in good health, it may last longer. There is no way to do this. If you want to play, you must make some sacrifices. . . . . . But there is one thing you have to do! That is to protect our eyes! Myopia is getting higher and higher, which is also related to playing with mobile phones in bed at night. We can only minimize the loss, so I will give you some good methods to effectively reduce eye pressure! 1. When you hide in bed and play with your mobile phone at night, try to keep the light on your mobile phone as low as possible, and don't put the mobile phone screen directly in front of your eyes. The light is direct and will not turn on its own (we won't consider interference diffraction), not to mention radiation. It is best to tilt it downward at about 45°C and not to tilt it upward. This will put a lot of force on your neck and cause pain after stretching for a long time. 2. Never lie on your side and play with your mobile phone! Listen clearly! Yes [Never]. Lying on the left and right sides has the greatest impact on the eyes. If this continues, it will cause vision deviation in the left and right eyes within a month. (Why do some people wear glasses with different powers on the left and right, while people are born with the same power in both eyes? It is because some people like to lie on the sides while playing with mobile phones, reading novels, and comics.) Pillows cause insufficient blood supply to the eyes. Over time, the eyes will feel swollen and short-term images will overlap. This cannot be cured with eye drops! So really, for the sake of our eyes, we really shouldn't do it! ! 3. Don't play with your phone while lying down. It causes difficulty in blood circulation in the elbows and brain. This method is very tiring, and it is also easy to fall asleep while the phone is still connected to the Internet. . . . Inert ischemia is basically formed above the cervical spine. 4. The best way is to play with the mobile phone while lying on your back, which is suitable for every part of the body. Except for tired elbows, you can use a quilt to pad under the elbows and continue playing! This is the best and least harmful way to your health. In addition, try to adjust the browser screen to night mode at night. We perceive fonts through color difference reaction. The greater the color difference between the two colors, the more eyesight is strained. The colors are: white, red, orange, yellow, green, blue, purple and black, and other derived colors are covered in it. Black and white are the most troublesome for the eyes. So you know why the night mode is always black and purple (or gray). Use cool tones at night, not warm tones. But there is a drawback: colors at night can easily make people feel tired. This is why you want to sleep after playing for a while at night (most people think that dark gray at night is better than black. This is also a color reaction problem, so I won't discuss it much) 5. Try not to play for more than one and a half hours at night! After people receive a certain amount of external information, they will avoid memory. (There are only two memory peaks in a person's day: around ten in the morning and around nine in the evening. The rest of the time, the memory is basic and not too active. However, after 11 in the evening, various parts of the body start a new round of metabolism. Everyone should pay more attention to it.) Also, make the browser fonts larger! 6. Don't turn on a small desk lamp when playing with your mobile phone at night. After 11:30 pm, the body will secrete protease that inhibits melanin, which can last until 4 am. However, if you see light during this period, the body will stop secreting it. . There will be secretion before one o'clock, and then there will be decomposition after one o'clock (please look at your little face, especially girls, if you have freckles. If there are freckles, there are only three reasons: too much sun; not washing your face thoroughly; not enough sleep. The second... the face is not washed... well... it depends on your own cleanliness, the third is up to you), and then the bags under the eyes will turn black, and it will take a long time to apply hot compresses to get better. 7. This... I think many people are like this. They eat a lot before hiding in bed and playing with their mobile phones at night. They are afraid of falling asleep while playing... Unexpectedly, the more they play, the more energetic they become... (The advantage of eating at night is that it can delay the arrival of the biological clock.The disadvantage is...the eyes will be swollen and constipated the next day, and the stomach will go on strike in the long run! ) Everyone really needs to keep the second point in mind! Really important! ! ! Finally, I would like to remind you: have a good rest and study hard!
