What is Pink Eye or Conjunctivitis?

Pink eye, medically known as conjunctivitis, is a common eye condition characterized by inflammation of the conjunctiva, the thin, clear tissue that lines the inside of the eyelid and covers the white part of the eye. It can affect one or both eyes and is often accompanied by redness, itching and discharge.

Common Causes of Pink Eye

Pink eye, also known as conjunctivitis, can be caused by a variety of factors. Understanding the underlying causes is crucial in determining the appropriate treatment and preventive measures. The three primary types of pink eye are viral, bacterial, and allergic conjunctivitis, each with its distinct causes:

Viral Conjunctivitis

Viral conjunctivitis is often the result of a viral infection, similar to the common cold. The most common viruses responsible for this type of pink eye include:

  • Adenovirus: This highly contagious virus can cause a range of symptoms, including pink eye. It's often spread through direct contact with infected individuals or surfaces.

  • Herpes Simplex Virus (HSV): HSV can cause not only oral and genital herpes but also ocular herpes, which can lead to viral conjunctivitis.

Bacterial Conjunctivitis

Bacterial conjunctivitis occurs when harmful bacteria infect the eye. Common bacterial culprits include:

  • Staphylococcus aureus: This bacterium is a common cause of bacterial pink eye, especially in children.

  • Streptococcus pneumoniae: Another bacterium known to cause bacterial conjunctivitis, often presenting with yellow or greenish discharge.

Allergic Conjunctivitis

Allergic conjunctivitis is triggered by allergens that your immune system recognizes as harmful, even though they are generally harmless substances. Common allergens include:

  • Pollen: Seasonal allergies, often referred to as hay fever, can lead to allergic conjunctivitis during specific times of the year.

  • Pet Dander: If you're allergic to pet dander, exposure to cats, dogs, or other furry animals can lead to eye irritation.

  • Dust Mites: Tiny creatures found in household dust can also be responsible for allergic conjunctivitis.

  • Mold Spores: Mold can release spores into the air, leading to allergic reactions in some individuals, including eye symptoms.

Diagnosis and Treatment


Diagnosing pink eye typically involves a physical examination of the eye and discussing your symptoms. In some cases, a swab of the eye discharge may be needed for lab analysis.


Treatment for pink eye depends on the type:

  • Viral Conjunctivitis: Usually resolves on its own. Over-the-counter lubricating eye drops can help alleviate discomfort.

  • Bacterial Conjunctivitis: Requires antibiotic eye drops or ointments prescribed by a healthcare professional.

  • Allergic Conjunctivitis: Managed by avoiding allergens and using antihistamine eye drops.

When to Seek Urgent Care

If you experience severe eye pain, vision changes, or suspect a foreign body in your eye, seek urgent care immediately. Additionally, if your symptoms worsen or do not improve within a few days, it's advisable to consult a healthcare professional.


To reduce the risk of pink eye:

  • Wash your hands frequently, especially before touching your eyes.
  • Avoid sharing personal items like towels or eye makeup.
  • Practice good hygiene, especially if you or someone close to you has pink eye.
  • Q: Is pink eye contagious?

    A: Yes, pink eye can be highly contagious, depending on its cause. Viral and bacterial conjunctivitis can spread through direct contact with infected eye secretions or contaminated surfaces. Allergic conjunctivitis, on the other hand, is not contagious, as it results from allergen exposure rather than a contagious pathogen.

  • Q: Can I wear contact lenses with pink eye?

    A: It's best to avoid wearing contact lenses until your symptoms have resolved.

  • Q: How long does pink eye last?

    A: The duration of recovery depends on the type of pink eye:

    • Viral conjunctivitis: Usually clears up on its own within one to two weeks.
    • Bacterial conjunctivitis: Typically improves within a few days of antibiotic treatment.
    • Allergic conjunctivitis: Symptoms can be managed with antihistamines and avoidance of allergens, but they may persist as long as the allergen exposure continues.
  • Q: What should I do if I suspect my child has pink eye?

    A: If you suspect your child has pink eye, it's important to consult a healthcare professional for proper diagnosis and treatment. Keep them home from school or daycare to prevent the potential spread of the infection to other children.

  • Q: Are there any complications associated with untreated pink eye?

    A: Yes, in some cases, untreated pink eye can lead to complications. For example, bacterial conjunctivitis left untreated can result in severe eye infections and potentially damage the cornea. It's essential to seek medical attention if you suspect pink eye to prevent complications.

  • Q: Can I use over-the-counter eye drops for pink eye?

    A: Over-the-counter lubricating eye drops (artificial tears) can provide relief for some pink eye symptoms, particularly in cases of viral or allergic conjunctivitis. However, they won't treat the underlying cause. It's best to consult a healthcare professional for a proper diagnosis and guidance on treatment options.
