It's Nearly Impossible to Sneeze With Your Eyes Open
Your body automatically closes your eyes when you sneeze, and it's extremely difficult to keep them open due to involuntary reflexes.
About this fact
Sneezing with your eyes open is nearly impossible due to an involuntary reflex built into your nervous system. When you sneeze, your brain automatically sends signals to close your eyelids as part of the sneeze reflex. This protective mechanism may have evolved to prevent debris, saliva, or mucus from getting into your eyes during the violent expulsion of air. While some people claim they can sneeze with their eyes open, it requires conscious effort to override the reflex and is extremely difficult. Contrary to urban legend, your eyes won't pop out if you manage to sneeze with them open - they're held in place by muscles and connective tissue.
