We're all familiar with the feeling―it usually starts with a little itch (痒) deep inside the nose. Next comes the awareness that it's going to happen. Then, achoo! Air rushes out of our nose at a shocking 100 miles per hour, bursting out whatever was causing the itch. The high-pressure from a sneeze (喷嚏) has led some people to think that if we didn't close our eyes, they could be pushed out.
For decades, countless people have tested the theory. When finding it almost impossible to keep their eyes open while sneezing, many have concluded that the theory must be true. If you try it yourself, the possibilities are that your eyes are still where they belong. That's because they are held firmly by the muscles in the eyes. Furthermore, increased pressure from sneezing actually builds up in the blood vessels (血管), which may cause vessels to break but may not be possible to push the eyeballs out.
Why did this theory start, anyway? Some say that it all began in 1882, when the New York Times reported an incident of a woman who burst one of her eyeballs during a sudden sneeze. Others point at the fact that different high-pressure experiences, such as childbirth, can cause blood vessels in the eyes to break out. Still others say that closing our eyes when we sneeze shows the theory is true. Scientists, on the other hand, explain that we close our eyes for the same reason we sneeze ― to prevent unwanted things from entering our bodies. Either way, as far as we know, there are no actual recorded cases of anyone losing an eyeball because of a sneeze, so don't lose any sleep over it!
