Conjunctivitis - Causes, Symptoms &Treatment

Conjunctivitis is a very common condition, sometimes referred to as “pink eye”.

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.

There are two main types of conjunctivitis: infective conjunctivitis which is caused by a bacterial or viral infection, and allergic conjunctivitis, which is caused by an allergic reaction to a foreign substance such as dust or pollen.

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.
