Conjunctivitis (Pink Eye)

Also known as pink eye, this is a very common condition that can affect one or both eyes.

What is conjunctivitis?

Conjunctivitis happens when the membrane that covers the front of the eye and inner surfaces of the eyelid (called the conjunctiva) becomes infected or inflamed. This can cause symptoms of burning, itchiness, redness, and in some cases, blurred vision.

Symptoms

Conjunctivitis can affect people of all ages, but is most commonly presented in children.

The symptoms of conjunctivitis may include:

  • Pink, bloodshot, or swollen eyes

  • Itchiness and swelling

  • A sandy, gritty feeling in the eye

  • A burning or itchy sensation in the eye

  • Sticky or dried discharge around the eyelashes

  • Blurred vision  

  • Light sensitivity 

Contact your optometrist immediately if you are experiencing any eye pain, sensitivity to light, impaired vision, or extremely red eyes. This may be a sign of a more serious eye infection that you should have examined.

Common causes

Conjunctivitis can be caused by a variety of things, which then affects the type of symptoms you experience and the recommended treatment.

Conjunctivitis causes include:

Infectious
  • Viral infection (such as a cold infection)

  • Bacterial infection (like staphylococci and streptococci)

Non‑infectious
  • Allergic reaction (such as pollen)

  • Local irritation (for example, shampoo, chlorine water, or a foreign body)

Treatment

The treatment for conjunctivitis will depend on the cause and severity of symptoms.   

In many cases, the symptoms resolve on their own and don't require any treatment, but sometimes it might need to be treated with things like antibiotic eye drops or antihistamines. If you experience any symptoms of conjunctivitis, you should visit your optometrist as soon as you can so they can see what’s going on and how to help.  

Conjunctivitis caused by microorganisms, such as bacteria and/or viruses, requires good hand hygiene to avoid spreading the germs. You should also avoid rubbing or touching your eyes and use personal towels and bedding, like pillowcases, while the infection lasts.

It’s important to follow your optometrist’s recommendations to make sure the chance of the infection spreading is limited. You should also take a break from wearing your contact lenses and make‑up while your eyes are irritated and to avoid contaminating your make‑up products.
