What is Conjunctivitis (Pinkeye)?

Conjunctivitis is a very common condition, sometimes referred to as “pink eye”. Conjunctivitis is one of the most common eye infections and is often seen in young children. It often appears as a red, swelling of the eye with possible discharge. If you’ve never had pink eye, consider yourself lucky! Although it rarely causes pain or long-term damage, it can be really unpleasant and annoying.

What Causes Conjunctivitis?

Some forms of conjunctivitis are caused by passing germs such as bacteria or viruses. This is called infective conjunctivitis, and it’s very contagious. Allergic conjunctivitis, on the other hand, is caused by allergic reactions to dust mites, pollen, or other irritating substances — and isn't contagious.

Signs and Symptoms of Conjunctivitis

The clear membrane over the white of your eye (conjunctiva) becomes inflamed, which can make your eye watery and feel itchy. Your eye may also become swollen, red, and produce watery or sticky discharge. Symptoms range from inconvenient to downright uncomfortable, but the good news is that it’s rarely very painful. The most common symptoms of pink eye, or conjunctivitis, are tearing, itching, redness, discharge, and swelling of the eye.

Treating Conjunctivitis

Conjunctivitis usually clears up within a matter of days to a week or two without treatment, but in some cases antibiotic eye drops or anti-allergy (antihistamine) medications will be needed. Please consult your optician if you think might have conjunctivitis.

Can bacterial conjunctivitis heal on its own?

Is it good to wash the eyes during conjunctivitis?

Rubbing your eyes, poor hand hygiene, sharing towels, and exposure to smoke or allergens can aggravate conjunctivitis or increase the risk of spreading it.

TL;DR - Conjunctivitis - Causes, Symptoms and Treatment

Conjunctivitis, commonly known as pink eye, is an eye condition that causes redness, irritation, and discharge. It can be triggered by infections like viruses or bacteria, or by allergies, and may spread easily if caused by germs. While symptoms often clear on their own, it’s important to avoid wearing contact lenses and to seek medical advice, especially if discomfort persists or vision changes. Practising good hygiene, like hand washing and avoiding touching your eyes, helps reduce the risk of getting or spreading conjunctivitis.
