Pink eye, medically known as conjunctivitis, is a common eye condition that causes redness, irritation, and inflammation of the conjunctiva, the clear membrane covering the white part of your eye. While often mild, conjunctivitis is highly contagious and affects millions of people annually.
Amidst discussion of its causes, a bizarre myth has persisted for years: can you get pink eye from a fart? It’s a question that’s often joked about on playgrounds and has become a recurring storyline in humorous pop culture. But how much of this claim is grounded in fact? Spoiler alert—not at all.
This blog will debunk the myth and provide a clear understanding of what causes pink eye, how it spreads, and how best to treat and prevent it.
What is Pink Eye?
Pink eye, or conjunctivitis, is an infection or inflammation of the conjunctiva, the transparent membrane protecting the eye. This condition can result from infections, allergies, or irritants. Pink eye typically presents with symptoms such as:
- Redness in the white of the eye.
- Swelling of the eyelids.
- Itching or burning sensations.
- A discharge that may cause the eyelids to stick together.
- Watering or tearing of the eyes.
Pink eye can be caused by viruses, bacteria, allergies, or exposure to irritants. According to the Cleveland Clinic, it is an incredibly common issue, with around 6 million cases of conjunctivitis occurring every year in the U.S. alone.
Different Types of Pink Eye
- Viral Conjunctivitis: Associated with watery eyes, often accompanied by cold-like symptoms, and is highly contagious. This type usually resolves on its own.
- Bacterial Conjunctivitis: Causes thicker discharge, often yellow-green, and can be treated with antibiotics.
- Allergic Conjunctivitis: Triggered by allergens like pollen or pet dander, it features intense itching and watery discharge but is not contagious.
- Irritant Conjunctivitis: Occurs due to irritants, like smoke or chlorine, and typically causes minor eye discomfort.
Debunking the Fart Myth
The Science Behind Flatulence
Flatulence, commonly known as a fart, is composed primarily of methane gas, along with smaller amounts of nitrogen, carbon dioxide, and trace odor-causing compounds like sulfur. While the thought of airborne bacteria riding a fart cloud may seem comical, it’s important to remember the following facts:
- Gas Composition: Farts consist mostly of odorless gases, which are incapable of carrying the pathogens required to cause pink eye.
- Bacteria Survival: Any bacteria that theoretically could be present would die immediately upon contact with the outside air.
- Transmission Pathways: Pink eye doesn’t spread through gas release; rather, it is transmitted through contact with bodily fluids that carry bacteria or viruses.
Verdict: A fart cannot give you pink eye. However, if fecal matter containing bacteria is somehow introduced to the eye via dirty hands, clothing, or contaminated surfaces, it could lead to a bacterial pink eye infection.
How Pink Eye Spreads
While farts don’t transmit pink eye, it is highly contagious and spreads easily through other means, including:
- Direct Contact: Touching your eyes after contact with infected tears, eye discharge, or contaminated surfaces.
- Shared Personal Items: Not washing shared items like towels, pillowcases, or makeup applicators.
- Hygiene Issues: Poor handwashing practices, especially after using the restroom or changing diapers.
Bacteria such as Staphylococcus aureus or Streptococcus pneumoniae can live on surfaces and infect the eyes if not properly cleaned.
Tips to Prevent Pink Eye
You can lower your risk of contracting or spreading pink eye by practicing these good hygiene habits:
- Wash your hands frequently, especially after using the restroom or touching shared items.
- Avoid rubbing your eyes to prevent transferring germs from your hands.
- Clean shared items, like towels, pillowcases, and makeup tools, regularly with hot water.
- Do not share personal items like makeup, eye drops, or face towels.
- For bacterial conjunctivitis, it’s best to stay home for at least 24 hours after starting antibiotics.
If you are a parent or someone who frequently changes diapers, take extra precautions to wash your hands thoroughly after each diaper change.
Symptoms and Treatments for Pink Eye
Symptoms Based On Type
Pink eye symptoms can vary depending on its cause, but common signs include:
- For Viral Pink Eye: Watery discharge, light sensitivity, and cold-like symptoms.
- For Bacterial Pink Eye: Yellow or green discharge, eyelash matting, and swelling.
- For Allergic Pink Eye: Severe itching, watery eyes, and swelling on both eyes.
Treatment Options
- Viral Pink Eye: There’s no specific treatment, but symptoms can be relieved with artificial tears or cold compresses. The condition usually resolves in 7–10 days.
- Bacterial Pink Eye: Treated with antibiotic eye drops or ointments. Symptoms improve quickly, but completing the full course of antibiotics is important.
- Allergic Pink Eye: Can be managed with antihistamine drops, avoiding allergens, or using artificial tears.
- Irritant Pink Eye: Symptoms often subside after removing the irritant and rinsing the eye with sterile solutions.
It’s advisable to consult an optometrist to determine the specific cause and receive appropriate treatment for pink eye.

The Bottom Line
To summarize, while the myth of getting pink eye from a fart is amusing, it holds no truth. Farts consist of harmless gases that cannot transmit the bacteria or viruses responsible for causing conjunctivitis.
Instead, pink eye spreads primarily through direct contact with infected eye fluids or contaminated surfaces. By maintaining proper hygiene and understanding how pink eye is transmitted, you can better protect yourself and your loved ones from this common but preventable condition.
If you do experience symptoms of pink eye, reach out to a healthcare professional for an accurate diagnosis and treatment plan. Remember, pink eye is overwhelmingly not serious and resolves on its own in most cases. However, maintaining good hygiene practices can help limit its transmission and ensure a speedier recovery.
