Question

Why do we close our eyes while sneezing?

It is due to an unconditional reflex action performed by brain

Answer 2

Answer:

Here's ur Answer Mate:-

Your chest expands in response, your lungs fill with air and then you sneeze everywhere.

You may shut your eyelids so that when you sneeze out germs they don't fall on your eyes.

Or maybe your eyes shut because they are one of a series of muscles that tighten during that involuntary response
