Urvashi Iyer, USA asked:
Can you keep your eyes open when you sneeze and if you do, will they pop out?
Chris: Iíve kept my eyes open in the name of objective research, whilst sneezing, to see what would happen. I can categorically say I still have my eyes, I can still see so I donít believe the idea that they pop out.
I think the reason we close our eyes when we sneeze is probably because you do get quite a big build-up of pressure in the nose. It will cause a sort of reflux of fluid back up the tear duct and it will squirt your tears back into your eyes. If you screw your eye up you squeeze that duct closed and it does stop some of the tear from squirting back into your eyes. Thatís why people say blow your nose if you have something in your eye because it forces some of the tears back up into your eye. It means that there are more tears in the eye for a short while. This helps to wash out everything. I donít believe sneezing makes your eyes pop out.
