Nowadays, mobile phones have basically become a tool that everyone can't live without. Many people like to play mobile phones before going to bed at night to release the stress of the day. Most people will choose to play with their mobile phones in bed, because this posture is more comfortable. In the latest issue of Happy Camp, Zhou Xun has been sticking a band-aid on his nose. Later, in He Laoshi's words, we learned that Zhou Xun played mobile phone because he was lying down. The mobile phone accidentally hit the bridge of the nose, and it bled at that time, so I had to stick a band-aid. Lying down to play with mobile phones is still very harmful, because lying down to play with mobile phones at first is not good for your eyesight, especially lying on your side, which may lead to different degrees of myopia between your two eyeballs. Secondly, if you lie down and play with your mobile phone, you are likely to get hurt if you fall. After all, a mobile phone is still quite heavy, and some mobile phones are angular and bruised.

Mobile phone is a very good tool, which can help people know what is going on outside without leaving home, and also allow people to see each other without leaving home. However, mobile phones also have great disadvantages, because the blue light emitted by the screen of mobile phones is very harmful to people's eyesight. There are many nearsighted primary and middle school students who always play mobile phones and stay up late, so they are nearsighted. Therefore, we should face up to the advantages and disadvantages of mobile phones, learn to use them and avoid using them. I think one of the great shortcomings of mobile phones is that people become lazy, just as people used to choose to write letters when expressing their feelings, and they also expressed their sincerity. Now everyone uses WeChat to send and receive messages to express their feelings faster, and the time to maintain a relationship may be shortened. Now this era is a fast-paced era, and everything is fast.

The human nose is a very fragile place. Many people will hit others on the nose when fighting, because once the nose is injured, it will last for a long time. Therefore, everyone must be careful not to bump into their noses when lying down and playing with their mobile phones. Many people like to turn off the lights at night, which actually hurts their eyes. Therefore, even if they want to play mobile phones at night, they should put a lamp on the bedside, so that the light on the screen of the mobile phone will also hurt their eyes.

Adults have a little stronger self-control, so it is normal for many adults to own a mobile phone, but the self-control of primary and secondary school students will be worse, so I think parents should not equip their children with mobile phones too early. If they are equipped with a mobile phone, they should also specify the use time of the mobile phone for their children and don't let them use the mobile phone for free.
