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

More about farts

Flatulence is the passing of intestinal gas through the rectum. The gas usually can be sourced to either intestinal bacteria working on undigested food or swallowed air.

Most humans pass gas (fart) a minimum of 14 times a day, according to the Cleveland Clinic.

Although not as common, certain medications can cause gas, such as the drug orlistat (Xenical), which is used to help maintain a healthy weight.

The drug cholestyramine (Questran), which is used to treat high cholesterol, can also cause gas.

Flatulence can also be a symptom of giardiasis (parasitic infection) or irritable bowel syndrome (IBS).

Healthline

Can you get pink eye from a fart? No.
