Bacterial Conjunctivitis: Symptoms, Causes, and Treatment

Bacterial conjunctivitis is an eye infection caused by bacteria that inflame the thin transparent layer covering the white part of the eye and the inner surface of the eyelids. The bacteria responsible for this eye condition can be spread through direct contact with infected individuals, contaminated objects, or poor hygiene practices.

It is essential to practice good hygiene, such as regularly washing hands and avoiding touching the eyes, to prevent the spread of bacterial conjunctivitis. Additionally, avoiding sharing personal items like towels or makeup can help reduce the risk of contracting the infection. Understanding the causes of bacterial conjunctivitis can empower individuals to take necessary precautions to protect their eye health.

Symptoms of Bacterial Conjunctivitis

Bacterial conjunctivitis, also known as pink eye, can cause symptoms such as redness in the white part of the eye, eye pain or discomfort, excessive tearing, discharge that may be yellow or green, and crusting of the eyelids or lashes, especially after sleep. If you notice these symptoms, it's essential to seek medical attention for proper diagnosis and treatment to prevent the spread of infection.
