The normal blinking frequency of ordinary people is 15 to 20 times a minute, but Mr. Li in Nanjing blinks more and more frequently, even reaching 80 times a minute. Blinking too fast has seriously affected Mr. Li's life. He can't drive and open his eyes normally, which is very uncomfortable. So Mr. Li came to the hospital for further examination, which was eyelid spasm. Let's talk about why people blink. In fact, this is a protection mechanism. As we all know, people's eyes are very fragile and need careful protection, but people's eyes actually have the ability to protect themselves, that is, blink.
When people's eyes are about to be hurt, they will send instructions to the eyelids through the brain, and then the eyelids will be closed to protect the eyes. But blepharospasm is more common in middle-aged women. The main causes of this disease are stress and brain degeneration. Due to the fast pace of social life, people can feel more pressure, and the high mental tension is reflected in their eyes, that is, they keep blinking. In addition, with the development of science and technology, various electronic products are flooding people's lives. In this way, people's eyes are much larger than before, so they start to feel uncomfortable and blink faster. Finally, as people get older, their brains will degenerate. So the degeneration of the brain drives the nerves, then the eyelids, and the result is an increase in the number of blinks.
Therefore, even in the busy life, we must take a vacation.
