Answer:
The medical term for a sneeze is the “sternutatory reflex”. Almost all animals
sneeze. A sneeze helps clear the nose and sinus regions while injecting
oxygen into the cells of the body. A sniff does much the same thing.
Nevertheless, a sneeze is a very complicated body action. Technically,
a sneeze is produced when an irritant contacts the nasal mucosa, which
in turn stimulates the trigeminal nerve, which in turn stimulates the pons and medullai of the brain, which in turn sets off additional nerve reactions, and so on. During a sneeze, tremendous stress is placed on the body. Considerable air pressure is place upon the eyes. This pressure is not enough to pop your eyes out of your head or even make them bulge out, but enough to make your eyes feel uncomfortable from the added pressure.

Answer:
The most common answer you’ll get is that it is a spontaneous nervous reaction. Now, I have proved, as have others, that you can sneeze with your eyes open. If you are having an episode where you’re repeatedly sneezing, you can prepare and force yourself to keep your eyes open. It is hard to do, but not impossible.

Answer:
This seriously cracked me up, come on guys, to halt your eyes popping out?
I tend to squint when i sneeze, but i don't fully close my eyes, sneezing does put a lot of pressure on your eyes, so its an instinctual reaction in order to protect and relieve pressure on your eyes as you sneeze.
That your eyes will pop out is fast becoming a scare tactic and myth.

A sneeze is actually way more violent than you might think. Contrary to many rumors and stories, your eyeballs won;t blow out of your head, but there is a whole lot of pressure that builds up in your sinuses and head.
