Can your eyeballs can be ejected by a sneeze?
Your eyes are actually quite secure, and your eye sockets aren’t connected to your nose at all. So, although a sneeze can erupt from your nose at an explosive 200 miles per hour, it can’t transfer this pressure into your eye sockets to dethrone your eyeballs. Plus, there’s no muscle directly behind the eye to violently contract and push the orbs outward.
