''It is unclear, but scientists theorize that we close our eyes to protect them. We may be protecting our eyes from microorganisms and particles from our sneezes," said Dr. Bonnie Henderson, director of comprehensive ophthalmology at the Massachusetts Eye and Ear Infirmary. But it could also be simply because a sneeze is a kind of bodywide reflex in which a lot of muscles contract, not just in the nose and throat but also those in the diaphragm, the abdomen, thighs, back, even sphincters (which is why some people with stress incontinence may urinate slightly when they sneeze).

Researchers aren't sure exactly why the sneeze reflex happens, but whatever neurological message tells the eyes to close probably comes from a primitive part of the brain called the medulla oblongata in the brain stem, Henderson said. And, it's not just an irritation in the nose that can trigger a sneeze; some people, probably because of genetics, have a photic reflex, which makes them sneeze in response to sudden, bright light.

And, in case you were wondering about that old wives' tale about the heart skipping a beat when you sneeze, rest assured: It doesn't, though it may pause for a fraction of a second before resuming its normal rhythm, said Dr. Thomas Graboys, director of the Lown Cardiovascular Research Foundation in Boston. That pause is believed to occur due to a change in intra-thoracic pressure, or pressure in the chest, when you sneeze. That pressure may stimulate the vagus nerve, which in turn slows the heart rate down for a brief moment.

This is not dangerous, Graboys noted. But it's believed that people began saying ''God bless you" when a person sneezes because they believed that, in that brief moment, you were between heaven and hell, and, if you were blessed, you'd be saved from damnation.

Q: Can you sneeze with your eyes open?

A: Some people can sneeze with their eyes open and some people can’t. Sneezing is a reflex and so is closing our eyes. We have no control over whether or not we close our eyes when we sneeze. Some people don’t have reflex, so when they sneeze then their eyes won’t close. Some people try to close their eyes so when they sneeze their eyes won’t pop out. Your eyes don’t really pop out. People without the reflex to sneeze with their eyes open can try to train themselves to sneeze with their eyes open. One good way to do this is if when you sneeze you hold your eyes open.

People think that when you close your eyes when you sneeze that you are blocking germs and bacteria. That is not true because your eyes deal with germs all the time. If you close your eyes during a sneeze, then it is just a reflex. During this part of the sneeze, we tense some of our muscles. The tensing (tightening) of our muscles causes our eyes to shut.

People that sneeze a lot can prevent sneezing. If you feel a sneeze, then use saline solution. You can also softly hold your nose at the end. These things can help your body remove things it does not want without sneezing.

No one knows the reason you close your eyes when you sneeze. There are many possibilities. Some people think it is to protect your eyes from flying goop. Most doctors think that it is still a reflex, or we just can’t help it.

Sneezing is very good for you and your body because it removes things from your body like bacteria and germs. It also is good because it keeps the tubes that carry the air from your nose to the lungs healthy. Sneezing makes your nose clear when you have a cold. If you used to hate sneezing, then I hope this has changed your mind.
