In today's world, while we enjoy the high speed and convenience brought by computers, we are also frequently troubled by "computer diseases": cervical spondylosis, dry eye disease, mouse hand, and carrot legs are gradually approaching us, causing us great harm. It has become an occupational disease for white-collar workers and the main cause of myopia among young students. Computer diseases are often formed slowly, and the harm to the body is not very obvious. It is most easily ignored by people, but it should not be underestimated. It will cause other diseases in the body, affect the quality of work and life, and cause potential harm to the human body. Therefore, people who use computers for a long time should do corresponding protective work. Computer disease, also known as video display terminal syndrome, is caused by using computers for too long, unscientific placement of computers, and poor computer room environment.
