What sort of disease is conjunctivitis?

Conjunctivitis: Inflammation of the coonjunctival tissues that covers the whites of the eyes and under the lids, due to allergy, infection or toxic effect of medicines/ chemicals. Conjunctiva become swollen and red. Patients experience burning, blurred vision, tearing, redness, puffy eyelids, discharge, itching, pain depending on the cause.

Eye Inlammation: Conjunctivitis means that the most superficial layer of the eye (the conjunctiva) is inflamed. This layer is normally clear, with a few arteries and veins, and covers the sclera (the white layer of the eye). When irritation occurs, from chemicals, viruses or bacteria, inflammation causes redness, and we call that conjunctivitis. Treatment depends on the cause of the redness.
