Closed. It's an instant reaction thing. Might be a myth, but I heard it's possible to have your eyeballs pop out if your eyes are open when you sneeze.

Yeah. That's a myth. But it is true that you can't sneeze with your eyes open. They close automatically (unless they're pegged open or something).
I can sneeze with my eyes open. It's hard, and I can't always do it, but I've done it enough times that I know for a fact that it's not impossible.
I practice it as a part of my martial arts training, so no one can take advantage of a sneeze to attack me.
thankfully you can't what makes it a good excuse if you would ever hit someone with a car. I now someone who in fauld crashed in a other car and he used that as a excuse and he actualy got a smaller penalty for it.
They have a show on the Discovery channel here in the US. They basically take all kinds of myths/urban legends and test them. It usually ends with something blowing up. http://dsc.discovery.com/fansites/mythbusters/mythbusters.html
Eyes closed. Also with my mouth wide open. I sound like a volcano going off. I’ve been known to get a “Bless You” from 150 ft and two walls away.
