Eye infection – Infectious conjunctivitis
Conjunctivitis is an inflammation of the conjunctiva (a thin transparent tissue covering the white part of the eye and the inside of the eyelids). It is often due to an infection - bacterial or viral - an allergic reaction or sometimes caused by a foreign body in the eye. It usually affects both eyes at the same time, but it may also occur in one eye only. Normally conjunctivitis is not very painful.
