What is pink eye? 

Pink eye, also known as conjunctivitis, is an inflammation of the thin layer covering the white part of the eye and the inside of the eyelids. It can cause redness, irritation, tearing, and discharge.  

While pink eye is often mild, certain types can spread easily, especially among children. In some cases, it requires prescription treatment to prevent complications. 

How do you get pink eye? 

Pink eye spreads differently depending on the type: 

1. Viral conjunctivitis 

This type is caused by a virus, often the same one that causes colds. Symptoms include watery eyes, redness, and mild irritation. Viral conjunctivitis usually clears on its own, but it can be very contagious.¹ 

2. Bacterial conjunctivitis 

Bacterial infections can lead to red, swollen eyes with thick yellow or green discharge. Bacterial conjunctivitis is highly contagious.¹ You can catch bacterial conjunctivitis through direct contact with eye discharge or objects touched by someone infected. 

3. Allergic conjunctivitis 

Allergic reactions to pollen, dust, or pet dander can cause itchy, watery eyes and redness in both eyes. Allergic conjunctivitis is not contagious.¹ 

Symptoms of pink eye 

Common signs of pink eye include¹: 

  • Redness in one or both eyes 
  • An itching or burning sensation 
  • A gritty feeling in one or both eyes 
  • Excessive tearing 
  • Discharge that may be watery or thick and pus-like 
  • Crusty eyelids, especially in the morning 
  • Sensitivity to light 

Recognizing these symptoms early can help you seek care before the condition worsens or spreads. 

How long does pink eye last? 

Pink eye can last different amounts of time based on the type: 

  • Viral: Usually improves within 1–2 weeks without prescription treatment.  
  • Bacterial: Often clears in 2–5 days with proper treatment. 
  • Allergic: Symptoms last as long as you’re exposed to the allergen.  

Pink eye treatment 

During an eye exam, our optometrist will examine your eyes closely and determine the type of pink eye. Treatment depends on the cause: 

  • Viral: This type of pink eye often goes away on its own. Using artificial tears and cold compresses can help your eyes feel more comfortable while they heal. 
  • Bacterial: Your eye doctor may recommend antibiotic drops or ointments to clear the infection and help you recover faster. 
  • Allergic: Antihistamine or anti-inflammatory drops can relieve itching and redness, and avoiding triggers like pollen or dust can reduce irritation. 

Children’s eye exams are especially important if pink eye symptoms appear at school, since early detection can prevent spreading and complications.  

People who wear contact lenses should wear glasses while they have pink eye. They should also switch to a fresh pair of contacts and a new case when their eyes are fully healed.  

Preventing pink eye 

You can reduce your risk of developing or spreading pink eye by: 

  • Washing hands frequently and thoroughly 
  • Avoiding touching or rubbing your eyes 
  • Using clean towels, pillowcases, and washcloths 
  • Keeping glasses and contact lenses clean 
  • Staying home if you or your child is contagious 

Following these steps helps protect your vision and the health of those around you.
