Excessive use of smartphones has seriously harmed the eyesight of young Chinese. According to the World health Organization, China has the world’s highest rate of childhood myopia, and by 2020, the number of myopic Chinese will reach

700 million. Myopia not only causes life-long problems, but also has a negative impact on young people’s future job opportunities. Moreover, smartphones also harm the mental health of children. According to studies, the brain of a child under 10 absorbs 60 percent more electromagnetic radiation than that of an adult. This can affect the normal functions of minors’ nervous systems, leading to sleep disorder, headaches and memory loss. Addiction to the virtual world will certainly reduce the number of opportunities children have to communicate with their peers and prevent them from having a good understanding of the real world, which, in the long run, may lead to mental illnesses such as autism. Students should not bring their smartphones to class. First, students should focus on their academic studies. using The use of smartphones on campus will negatively influence children’s lives.

First, smartphones are sometimes used as tools for cyberstalking and provide easy access to violent and pornographic images via the Internet. Second, the presence of smartphones in schools can also lead to an unhealthy competition between children, who come from different families with different economic backgrounds. In addition, the need to equip every child with a phone will eventually increase the economic burden on families.
