Pink eye, medically known as conjunctivitis, is a common eye condition involving inflammation of the conjunctiva, or inner lining of the eyelid. Conjunctivitis may be caused by a virus, bacteria or allergens and is highly contagious. Additionally, foreign bodies in the eye can also irritate the conjunctiva, as well as air pollution, smoke, dust and chemical vapors.
In Our Own Words
Conjunctivitis, or pink eye, is one of the most common eye infections affecting both adults and children, even newborns. Bacterial and viral forms of conjunctivitis are both highly contagious. Your conjunctiva lines the inside of the eyelid and covers the white part of the eye; it contains tiny blood vessels and is usually transparent. When the tissue becomes irritated, those blood vessels become larger and make the eye appear reddish.
It can be difficult to determine exactly what causes this inflammation: An allergen, bacteria, a virus or another reason. Serious conditions that result in vision loss are ruled out first by health care professionals, and prompt treatment of bacterial conjunctivitis is highly effective and can prevent contagion
