The myth that farting on pillows can cause pink eye is not true.

Dr. Amir Mozavi supports that conclusion.

He points out in a 2017 article that flatulence (farting) is primarily methane gas, and methane gas doesn’t contain bacteria. Any bacteria present in the fart would die quickly once outside the body.

Poop — or more specifically, the bacteria or viruses in poop — can cause pink eye.

According to the Centers for Disease Control and Prevention (CDC), if your hands contain fecal matter and you touch your eyes, you can get pink eye.

The American Academy of Ophthalmology recommends avoiding directly touching your anus and then directly touching your eye. You could transfer bacteria that can cause bacterial conjunctivitis, a common form of pink eye.

Pink eye, or conjunctivitis, is an infection or inflammation of the conjunctiva. The conjunctiva is the clear membrane that covers the white part of your eyeball and lines your eyelid.

Pink eye is commonly caused by:

According to the Mayo Clinic, conjunctivitis is contagious, but about as contagious as the common cold.

To manage the transmission of pink eye, practice good hygiene, such as:

  • washing your hands often, especially after going to the restroom
  • avoiding touching your eyes
  • throwing away contact lenses worn since contracting pink eye
  • using clean washcloths and towels daily
  • avoiding share washcloths, towels, personal eye care items, or cosmetics
  • changing your pillowcases often

Can you get pink eye from a fart? No.

However, pink eye is a contagious medical condition. You can take steps to prevent its transmission by practicing good hygiene and not touching your eyes with unclean hands.
