Have you ever wondered why we automatically close our eyes when we sneeze?

According to urban legend, it’s to prevent our eyes from popping out of their sockets – in medical terms, that’s called “eyeball subluxing.” But doctors say there’s a 99-point-9-percent chance that won’t happen, because your eyes contain muscles which hold them in the socket. And there’s zero modern medical evidence that eyeballs can sublux from sneezing. 

In fact, even though it feels like your entire face is building up with pressure as you sneeze, your eyes experience zero pressure. That’s because our nasal passages act as a pressure buffer between our face and eyes.

So why do we shut our eyes when we sneeze? It’s just an involuntary reflex. When our brain sends the message to our body to sneeze, one part of the message is to close our eyes. It’s just like when a doctor taps on your knee with a tiny hammer and your knee automatically jerks.
