With the development of China's economy, the level of science and technology has also been greatly improved, and various electronic products have come out accordingly. Electronic products are very attractive to both old people and children. Especially for children, physical and mental development is still in an imperfect state, and self-control is relatively poor. There is no resistance for electronic products.

However, electronic products are harmful to people's health, especially to children. No matter how big the radiation is, it is harmful for children to watch electronic products for too long. If they watch cartoons and other videos on TV or mobile phones, they will watch them episode by episode without the supervision of adults, but they will concentrate on their eyes for a long time and have no rest time, which is harmful to their eyes.

Moreover, children are in the time of school and class, and school and class are originally a process with eyes. Besides, I have to do my homework when I go home. If you use your eyes for a long time, your eyes won't get a rest, and you will definitely feel tired and probably get hurt. Therefore, experts suggest that protecting eyesight should start from the age of zero. First of all, we should pay attention to the combination of work and rest at ordinary times, and do appropriate outdoor exercise after using our eyes to rest and relax our eyes.

Secondly, we should control the time children spend playing electronic products, such as playing mobile phones, and strictly control the time watching TV. And when playing electronic products, we should also pay attention to the brightness of the screen to avoid more irritation to the eyes. When attending class or doing homework, keep a certain distance from books and textbooks, and pay attention to the correct sitting posture and the distance from the desk. After studying, do some eye exercises during recess to relax your eyes.

Finally, parents must take strict care of their children. Children are young and have weak self-control. Parents should do their duty to prevent their children from being nearsighted from childhood.
