The dilation of the conjunctiva makes the eyes become reddish.Factors that may expose the eyes to redness include infection, inflammation and allergic reaction to certain foods or drugs. In most cases however, the leading cause of red eyes is conjunctivitis.
Conjunctivitis is a medical condition characterized with the inflammation of the surface of the eye which may be attributed to infection and irritation.
It is important to know that when there is a discharge from the eyes, the likely cause is either bacteria or viral infection. A stickier discharge is associated with bacteria. An infectious conjunctivitis easily spread to the two eyes and is often caused by common cold while a noninfectious conjunctivitis is often caused by an allergic reaction.
