Closing your eyes is a natural reaction for several reasons: strong wind blasts and, of course, sneezing. It's mainly to keep your eyes protected from the resulting dust and mist. Your eyes will not pop out of your head, your actual sockets would hold them in! This is a myth. I don't know how it got started, but it's not true.

Not everyone sneezes harder when they look at a light.  However, some people have the Photic Sneeze Reflex.  They do sneeze in bright  light.  \n\nThe most prominent theory, from Wikipedia - Photic Sneeze Reflex - http://en.wikipedia.org/wiki/Photic_sneeze_reflex  is\n"The probable cause is a congenital malfunction in nerve signals in the trigeminal nerve nucleus. The fifth cranial nerve, called the trigeminal nerve, is apparently responsible for sneezes. Research suggests that some people have an association between this nerve and the nerve that transmits visual impulses to the brain. Overstimulation of the optic nerve triggers the trigeminal nerve, and this causes the photic sneeze reflex."\n\n----\nSee also OMIM - ACHOO: http://en.wikipedia.org/wiki/Mendelian_Inheritance_in_Man

A sneeze happens with tremendous speed and pressure, and you can feel it coming, if a ball is coming at you extremely fast, or anything for that matter, it's our instinctive response to close our eyes. I was in a car accident and as soon as the car went off the road, I closed my eyes, there was nothing else to do. We're just people.

The most common belief is that your soul leaves the body for a short time, so by saying "bless you! (from "bless your soul") the person would be protected. It is also true that your heart stops when you sneeze. The "bless you" is also supposed to keep the devil from entering your throat when sneezing. In Romanian, for example, we say either "health" or "luck", we don't use the "bless you".

Because the pressure of the sneeze, you close your eyes. You can't control them because its something the body controls. Try holding your nose or biting your tongue though if you're about to sneeze. Then you don't.

You might be allergic to the grass especially if your eyes get red and itchy and you get sneezy or sniffly.

First of all not all people sneeze multiple times in a row.  The reason for sneezing is your body's primary defense against something trying to get in that shouldn't be there such as dust, pollen, bacteria, etc.  The little hairs in your nose are very sensitive and when something moves them it gets trapped inside and sneezing is how your body expels the invader from your nose or throat if it made it that far although coughing is usually more related to the throat.

Usually the sneezing relex make your eye lids to close.

"Close association between the eye’s optic nerve and nerves causing the sneeze reflex may explain why an estimated 5-25% of people sneeze with sudden exposure to bright sunlight or other light sources.\n\nSudden bright stimulation of the eye that occurs after a person has become adapted to darker surroundings is thought to bring on the condition, known as photic sneeze reflex."

Your eyes are forced shuh by a part of the brain that refuses to look at the booger bits that go flying out when you sneeze.\n\nYou have overcome it looking at stuff like go-at-se until that part of the brain just gives up.

Pretty much the same reason people sneeze when they get a cold: it's one of the mechanisms the body uses to get rid of infection, poison or other bad elements.  With a cold, of course, the infection is in the respiratory system; with diarrhea and/or vomiting, the problem is in the gastrointestinal tract.  It's your body's way of "evacuating the building" so your antibodies and other immune mechanisms have a better chance of conquering the infection.\n\nThere can be other reasons for diarrhea, however.  One is where you have eaten something which for some reason your body isn't equipped to digest properly.  There are also some GI diseases where your digestive system isn't working the way it should.  One such disease is called Irritable Bowel Syndrome, where your digestive system is overly sensitive to irritants.  Stress is another thing which can cause temporary diarrhea.

well...I think that`s because when you sneeze, cough or laugh hard...your diaphragm contracts and the body is concentrated very hard on that muscle.When you cough..sneeze etc. you blow out CO2 and your body tries to get rid of it with the help of every space that leads from your body outside your body, for example : when you sneeze you have tears coming out of your eyes...that`s because it`s a sensitive tissue that produces water and has to get out fast from your body in case of emergency ... like crying(because of the nerves that must relax), laughing hard etc... I hope the answer helps..and you also must consider the answer above...with the weak muscles

because scientists studied that if you dont close your eyes when you sneeze your eye balls pop out.
