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.
