The most distant distance in the world is not the end of the world, but I am standing in front of you, but you are playing with the phone. Some people say that the cell phone is an extension of the human organ, has become a human “digital organ”. If you ask your colleagues and friends around you, “What do you do before you go to bed at night and the first thing in the morning when you open your eyes?” I think the majority of answers will be “look at the phone”. ”Long time playing cell phones, blinking times significantly reduced, be careful of visual fatigue, dry eye disease.” Long hours of playing games, browsing the web, and brushing microblogs on cell phones and computers can significantly increase the fatigue of the eyes, hands and joints. Especially for teenagers, the damage is even worse. Some experiments have confirmed that playing cell phones continuously for one hour will temporarily deepen the degree by 100 degrees. If this continues, the eyes can not get effective relaxation and rest, may lead to irreversible deepening of the degree. In addition, many people are accustomed to playing with cell phones when taking public transportation or subway, which will also add importance to fatigue symptoms. For patients after myopia laser surgery, playing with cell phones for a long time may lead to aggravation of dry eyes and recurrence of myopia. If you find that the situation of visual fatigue becomes serious, you need to go to a regular hospital as soon as possible to avoid affecting your vision.
