It is impossible to sneeze with your eyes open !

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. According to Dr. G.H. Drumheller of the International Rhinologic Society in Milan, we close our eyes when we sneeze in order to keep the eyes from “extruding”.
