Pink eye, also known as conjunctivitis, is a common eye condition characterized by inflammation and redness of the conjunctiva. The conjunctiva is a thin, clear tissue that covers the front surface of the eyes and the inner surface of the eyelids. Pink eye is typically caused by a bacterial or viral infection, but can also result from an allergic reaction or exposure to irritants.
In the case of a bacterial infection, such as with Staphylococcus or Streptococcus bacteria, pink eye is highly contagious and can easily spread from person to person through direct contact or sharing of contaminated objects. Viral conjunctivitis, commonly caused by adenoviruses, is also contagious and may be associated with symptoms of cold or respiratory infections. Allergic conjunctivitis, on the other hand, results from an allergic reaction to substances like pollen, pet dander, or certain medications.
Signs and symptoms of pink eye include redness and swelling of the eyes, irritation, watery discharge, itching, light sensitivity, and in some cases, blurred vision. The condition can affect one or both eyes and may gradually or rapidly develop depending on the underlying cause. Proper hygiene practices, such as regular handwashing, avoiding touching the eyes, and disinfecting shared items, can help minimize the risk of spreading or contracting pink eye.
Treatment for pink eye varies based on the cause. Viral conjunctivitis often resolves without treatment within one to two weeks, while bacterial conjunctivitis may require antibiotic eye drops or ointments. Allergic conjunctivitis can be managed by avoiding allergens or using antihistamine eye drops.
