When you sneeze the air from your nostrils come out with great force (infact stronger than the strongest wind!).\n\nIt is said that if you sneeze with your eyes open, your eyeballs might pop out!! It may be possible as our eyeballs are just held in sockets and do not have supportive structures to hold them in place.\n\nWhen you try to hold back a sneeze, your eyes start watering a little bit.

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.\n\n    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.\n\n    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.\n\n    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.\n\n    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.

I think its physically impossible to sneeze while you sleep, without waking up.

Generally, the eyes close to shield them from flying debris, as in that jettisoned from your nostrils.  If you want to be blinded by a booger, fine -- I'll close my blinkers until the sneezin' is done.

Do you mean "why do we close our eyes when we <sneeze>?"?\n\nWhat a wonderful way to phrase that question :-)\n\nYou can find some answers at these sites:

I dont agree with the question to begin. It doest necessarily have to occur like this. Ive heard a lot of people sneeze and not everyone sneezes after them.

A sneeze is the fastest known action that a human can perform.  It is involuntary and can make the head mover VERY sharply.  Maybe our eyes close so that we don't get anything in them when our head jerks forward?  Dust, leaves, branches, etc. would be both painful and dangerous if they got into our eyes while we were moving our head at high speed.\n\nAccording to Wikipedea:\nIt is almost impossible for a person to keep their eyelids open during a sneeze, although some rare individuals report having little if any trouble doing so. The reflex of shutting the eyes serves no obvious purpose: the nerves serving the eyes and the nose are closely related, and stimuli to the one often trigger some response in the other.

You sneeze because you have something in your nose and your body is trying to get it out.  You don't get it out the first time, or your nose is still irritated.

Mechanism of sneezing - Normally, sneezing is an involuntary reflex, which is controlled by a complex interaction of nerve fibres. A variety of receptor sites, situated in the nose, reports about the irritation or foreign substance to the brain for inducing sneezing by releasing histamine, for clearing the nose. Receptors are sensitive to infection, touch, smells of dust, chemical gases, fumes, temperature and exposure to extreme cold air and water (the main offender). Usually, sneeze begins with a deep inspiration and closed glottis, which suddenly opens after gaining pressure from contraction of the diaphragm, abdomen muscles and other muscles which compress the lungs to let out the trapped air with force through nose and mouth. So with an explosive sound, throw of air occurs as a sneeze. Sneezing also involves contraction of the muscles of face, neck and eyes. Sometimes, sneezing air speed is measured more than 120 km/per hour. Normally, people sneeze once or twice during early morning or daytime to clear the nose.\n\nFor more info, go to the source...

gggeeez.. No..  How could that be possible?  You have tons of muscles and whatnot holding them in!  That is just silly.  You can try sneezing with your eyes open, but it just doesn't happen.  There is no need to worry.

Sorry, we don’t know why most people close their eyes when sneezing. Not all do. \n\nSome experts guess that we’ve evolved closing eyes to reduce sneeze spray landing in our eyes. However, our eyes are exposed constantly to bacteria and viruses and have good defenses without eye closing.\n\nClosing eyes (or keeping them open) is part of the sneeze reflex. It’s a reflex—meaning we have no conscious control of sneezes. Instead, the primitive part of the brain (called the medulla oblongata and located at the top of the spine) calls the shots. The reflex triggers major muscles of face, throat, and chest to fire out gunk going at 100 mph (150 kph) as fast as a pitcher’s fastball.\n\nMost people tighten the eye muscles, causing them to shut, as they tighten the other muscles involved in a sneeze. But not all do. Some sneeze with their eyes open. Either way, it’s part of the inborn sneeze reflex.\n\nIn 1888, Thomas Edison hit upon the idea of movies from looking at sequential pictures of someone sneezing

You sneeze with your eyes open.

It is not the sun that is stopping you from the sneeze, it is the position of your head. you can look at the moon or a a piece of key lime pie that is floating in the sky and have the same result.

If you did manage to sneeze with your eyes open, your eyes would pop out of your head.   Er, no. As discussed above, some people do manage to sneeze with their eyes open, and they don't go blind from it. Eye sockets are made of bone, they aren't connected to the nasal passages, and there are no muscles behind the eyes that contract when you sneeze, so there's really no mechanism involved in a sneeze that could force your eyes out of their sockets. Even if there were, human eyelids aren't particularly strong, so simply closing your eyes during a sneeze wouldn't be sufficient to keep them in their sockets if a sneeze truly had enough power to dislodge them. (In any case, some people — due to circumstances such as birth defects or injury — do not have eyelids. Were the "eye-popping" rumor true, all of those people would have to spend their lives in constant mortal fear of sneezing.)
