Red eyes, inflammation or discharge from the eye can be due to many causes, including infection or allergy.
To determine if you have conjunctivitis a swab of the conjunctiva helps with diagnosis and treatment.
Conjunctivitis is a very contagious eye infection that causes redness, swelling and discharge from the affected eye. Despite its unsightly appearance, it usually clears up on its own after a couple of days but can be very uncomfortable.
It’s also very easy to pass conjunctivitis from one eye to another, or one person to another, so always wash your hands and try not to rub the affected eye.
