What is Pink Eye
Pink eye, also known as conjunctivitis, is an inflammation or infection of the conjunctiva, the thin, transparent membrane that covers the white part of the eye and lines the inner surface of the eyelids. It is called "pink eye" because the inflammation often causes the blood vessels in the conjunctiva to become more prominent, giving the eye a pink or reddish appearance.
Causes of Pink eye
Viral Infection: Viral conjunctivitis is highly contagious and is often associated with common cold viruses or other viral infections. It typically spreads easily through direct contact with infected individuals or touching contaminated surfaces.
Bacterial Infection: Bacterial conjunctivitis is caused by bacteria and can occur as a result of an eye infection or secondary to another infection, such as a respiratory infection. It can also be transmitted through direct contact or contaminated objects.
Allergies: Allergic conjunctivitis is triggered by allergens such as pollen, pet dander, dust mites, or certain chemicals. It often affects both eyes and is associated with itching, redness, and watery discharge.
Irritants: Non-infectious conjunctivitis can also be caused by irritants such as chemicals, smoke, or foreign objects that come into contact with the eye.
Newborn babies can develop pink eye due to a blocked tear duct or as a result of an infection acquired during birth. This is called neonatal conjunctivitis and can be caused by bacteria or viruses.
