Pink Eye (Conjunctivitis): Causes, Symptoms, Treatment & Preventing

Pink Eye, medically known as Conjunctivitis, is a common eye condition characterized by inflammation and redness of the conjunctiva – the clear tissue that covers the white part of the eye and the inside of the eyelids. It can occur due to various causes such as bacterial or viral infections, allergies, or exposure to irritants. Conjunctivitis can be quite discomforting, although it rarely affects vision. Understanding its causes, symptoms, treatment, and preventive measures can help manage this condition effectively.

What is Pink Eye?

Pink Eye is a highly contagious eye condition that can affect anyone, regardless of age or gender. It is typically caused by a virus or bacteria and can also be triggered by allergies or exposure to irritants such as smoke or chemicals. In some cases, pink eye may also be associated with underlying health conditions like dry eye syndrome, autoimmune disorders, or sexually transmitted diseases. It is essential to identify the specific cause of pink eye for proper treatment and prevention.


As mentioned earlier, Pink Eye can be caused by various factors. The most common causes include:

  • Bacterial Infections: Certain bacteria like Streptococcus pneumoniae or Staphylococcus aureus can cause pink eye. These bacteria are highly contagious and easily spread through direct contact with an infected person’s eye discharge or contaminated objects.
  • Viral Infections: Pink eye caused by a virus is the most common type and is highly contagious. Adenovirus, herpes simplex virus, and varicella-zoster virus are some viruses that can cause conjunctivitis.
  • Allergies: Seasonal allergies or exposure to allergens like pollen, dust mites, or pet dander can trigger an allergic reaction in the eyes and cause pink eye.
  • Irritants: Contact with irritants like smoke, chemicals, or chlorine in swimming pools can also lead to conjunctivitis.


Symptoms of Pink Eye can vary based on the cause but commonly include:

  • Redness in the white of the eye or inner eyelid
  • Increased tear production
  • A feeling of grittiness in the eye
  • Experiencing thick yellow discharge that forms crusts on the eyelashes, particularly noticeable after waking up.
  • Green or white discharge from the eye
  • Itching and burning sensation in the eyes
  • Blurred vision
  • Increased sensitivity to light

It’s important to note that these symptoms can range from mild to severe and may affect one or both eyes. If you experience any of these symptoms, it is advised to seek medical attention promptly.

Treatment for Pink Eye

The treatment for pink eye depends on the cause. If it is caused by a virus, it will typically clear up on its own within one to two weeks without any specific treatment. However, if the infection is bacterial, your doctor may prescribe antibiotic eye drops or ointments.

If pink eye is triggered by allergies, antihistamines or allergy eye drops may be recommended to help relieve symptoms. For conjunctivitis caused by irritants, flushing the eyes with cool water or using artificial tears can soothe the irritation.

In addition to these treatments, your doctor may also advise you to:

  • Refrain from using contact lenses until the infection has completely cleared.
  • Use warm compresses to alleviate discomfort
  • Practice good hygiene, such as washing your hands frequently and avoiding touching or rubbing your eyes
  • Replace any eye makeup or contact lens solutions that may have been contaminated with fresh and clean ones to ensure proper hygiene and avoid potential risks to your eyes.


The best way to prevent pink eye is to practice good hygiene and avoid coming in contact with infected individuals. Here are some tips that can help reduce the risk of getting pink eye:

  • Wash your hands frequently, especially before touching your eyes
  • Avoid sharing personal items like towels or eye makeup with others
  • Keep your contact lenses clean and follow proper hygiene while handling them
  • Avoid touching or rubbing your eyes, even if they feel itchy or irritated
  • If you have allergies, take necessary precautions to avoid allergens and use prescribed medications as recommended by your doctor
  • If you have pink eye, avoid contact with others until the infection clears to prevent spreading it.
