The most obvious symptom of pink eye is, of course, a pink eye. The pink or red color is due to inflammation. Your eye may also hurt or itch.
How can you tell what type of pink eye you have? The way your eyes feel will give some clues:
Viral conjunctivitis usually affects only one eye and causes excessive eye watering and a light discharge.
Bacterial conjunctivitis affects both eyes and causes a heavy discharge, sometimes greenish.
Allergic conjunctivitis affects both eyes and causes itching and redness in the eyes and sometimes the nose, as well as excessive tearing.
Giant papillary conjunctivitis (GPC) usually affects both eyes and causes contact lens intolerance, itching, a heavy discharge, tearing and red bumps on the underside of the eyelids.
To pinpoint the cause and then choose an appropriate treatment, your doctor will ask some questions, examine your eyes, and possibly collect a sample on a swab to send out for analysis.
Give a careful account of the episode, because oftentimes your answers alone with reveal the diagnosis.
