What is Pink Eye?
Pink eye, medically known as conjunctivitis, is an inflammation or infection of the transparent membrane (conjunctiva) that lines your eyelid and covers the white part of your eyeball. When small blood vessels in the conjunctiva become inflamed, they're more visible. This is what causes the whites of your eyes to appear reddish or pink.
Conjunctivitis can be caused by infections, allergies, or irritants. It is important to identify the type of conjunctivitis to apply the correct treatment and prevent its spread. The condition can be uncomfortable, but it rarely affects vision.
Types of Pink Eye
Viral Conjunctivitis
Viral conjunctivitis is the most common type and is caused by viruses, such as adenovirus. It's highly contagious and can spread through direct or indirect contact with the eye secretions of an infected person.
Bacterial Conjunctivitis
Bacterial conjunctivitis is caused by bacteria and can affect one or both eyes. Common bacterial agents include Staphylococcus aureus, Streptococcus pneumoniae, and Haemophilus influenzae. This type can also be contagious and requires antibiotic treatment.
Allergic Conjunctivitis
Allergic conjunctivitis occurs when the eyes react to allergens like pollen, dust mites, or pet dander. It is not contagious and typically affects both eyes. Symptoms include intense itching, redness, and tearing.
