Key Takeaways

Pink eye cannot be caused by farting; however, poop bacteria can cause it so you need to wash your hands properly after using the restroom.
Pink eye (conjunctivitis) is caused by a virus, bacteria, or an allergic reaction.
Most cases resolve themselves without intervention. Antibiotics are effective only in bacterial infections.
Red and watery eyes, crusty yellow discharge, and a tender, gritty sensation are some of the symptoms.
Pink eye can occur in adults, although it is more prevalent in children.
The myth that farting can cause pink eye is widespread, however, it is scientifically impossible to get it through gas alone.

What is pink eye?

Pink eye, or conjunctivitis, occurs when the conjunctiva (the thin membrane covering the whiteness of the eye) becomes inflamed. This can make the eye appear pink or red and cause substantial discomfort.

The Three Main Types of Pink Eye are:

Viral conjunctivitis – Caused by cold or flu viruses. It is easily spreadable and self resolving within one to two weeks without the need of antibiotics.
Bacterial conjunctivitis – This can be caused by bacteria Staphylococcus aureus or Haemophilus influenzae. This form of conjunctivitis is quite responsive to antibiotic drops or ointments.
Allergic conjunctivitis – Caused by allergens such as pollen, dust mites, and pet dander. Often seasonal and not transmissible.

How Is Pink Eye Spread?

The viral and bacterial types of pink eye are some of the easiest infections to spread. They can be spread through:

Eyes being rubbed after touching a contaminated surface
Using the same towel, makeup, or pillowcase.
Closely confined places such as daycare, school, and workplace.
Poorly maintained contact lenses.

Your eye is very susceptible to infection anytime it is exposed to even the smallest amount of harmful microorganisms.

The “Fart Causes Pink Eye” Myth

This rumor is fueled especially by the movie Knocked Up, which popularized the claim that pink eye can be caused by “farting” on a pillow.

Here are the explanations why that does not hold.

Conjunctivitis is not caused by the substances that combine to form fart gases such as methane, nitrogen, and carbon dioxide.
Farting does not release poop’s bacteria in anything close to contagious quantities.
Natural filters such as clothing and skin hinder bacteria’s ability to float freely, so it’s not possible to freely float.

A fart may be odorous, but it can never serve as a delivery system for pink eye. The actual problem is fecal matter transferred from hands, especially if a person rubs their eyes after the rest room without washing.

Can Farts Ever Transmit Germs?

If a person is farted upon while fully unclothed, there is a small possibility some bacteria may be released. But the chances of pink eye developing from that situation is next to none. The majority of eye cases arise due to hand-to-eye interactions after directly touching contaminated surfaces.

To summarize:

Gas = non-infectious
Fecal matter = possibly infectious.
Risk from flatulence: next to none.

Real Risk Factors for Pink Eye

Rather than worrying about flatulence, consider these recognized risk factors:

Not washing hands after toilet use.
Using shared cosmetics, towels, and face cloths.
Unwashed pillowcases leading to sleep.
Close proximity to a eye sufferer.
Unchlorinated and dirty swimming water.
Inadequate lens hygiene.

How to Prevent Pink Eye

Contagious as it is, eye pink can be easily prevented through proper hygiene. Here is what reinforces it:

Daily activities:

Frequent handwashing with soap.
Avoid eye rubbing and touching.
Practice good hygiene in caring for contact lenses and their respective cases.
Wash pillowcases and towels more often than usual.

For individuals sharing a home with a pink eye patient:

Avoid sharing towels, bedding, and makeup.
Clean shared objects such as doorknobs and remote control.
Exclude symptomatic children from school and daycare until evaluated by a physician.

For pink eye due to other allergies:

Implement air purifiers and air conditioning in the hot months prone to allergies.
Avoid opening windows on days with high pollen.
Use antihistamines and allergy eyedrops when necessary.

Is It Pink Eye, or Something Else?

A multitude of issues could be responsible for a red eye, and not all of them would be conjunctivitis. They include:

Dry eye syndrome – the chronic inability to produce adequate tears.
Blepharitis – inflammation of the eyelids.
Corneal scratches – Corneal abrasions.
Subconjunctival hemorrhage – also known as burst blood vessels in the eye.
Glaucoma – A serious and urgent eye condition.

Save big on glaucoma treatments.

Seek immediate medical help if you experience:

Change in vision.
Acute pain or eye redness.
Reduced light tolerance.
Prolonged symptoms of a few days.

How to Treat Pink Eye?

For eye of viral and allergic etiology, management is symptomatic for the first 1–2 weeks.To minimize complications and reduce viral spread associated with Bacterial conjunctivitis (pink eye), antibiotic drops or ointments may be required.

At-home relief tips:

Warm compresses for soothing comfort.
Use of artificial tears for dryness and eye irritation.
Over-the-counter medications like ibuprofen for pain alleviation.
Stop wearing contact lenses until symptoms disappear.

Consultation with a healthcare provider is advised if symptoms worsen or do not improve in a few days.

Final Verdict

The consensus is a firm no; fart gases will not cause pink eye. The most likely scenario for poop bacteria to cause conjunctivitis would be a direct, hands-eyes contact transfer.

Therefore, the culprit of worry is a fart near the pillow, which should be forgotten. The advised method to guard against eye is to wash your hands, maintain a clean environment, and avoid eye touching.
