Ophthalmology Knowledge: Is Conjunctivitis Contagious?

　　Conjunctivitis—commonly known as “pink eye”—is a contagious form of conjunctivitis, also referred to as acute epidemic conjunctivitis. Patients infected with pink eye typically experience symptoms such as ocular warmth, pain, photophobia (light sensitivity), and difficulty opening the eyes, significantly impairing daily activities. So, does pink eye spread from person to person? Let’s explore this question through ophthalmological knowledge.

　　Does pink eye spread? Ophthalmological insights

　　Yes, pink eye is highly contagious. Transmission occurs primarily via direct or indirect contact. Infection may result from touching an infected person’s eyes and then touching your own eyes. It can also occur when an infected individual touches their eyes and subsequently handles other objects; if a healthy person later touches those contaminated surfaces and then rubs their own eyes, infection may follow. Therefore, patients with pink eye should thoroughly wash their hands before and after touching their eyes and must avoid sharing personal hygiene items—including towels and bedding—with others.

　　In the early stages of pink eye, treatment under medical supervision is recommended, using appropriate topical antibiotics to control inflammation—for example, levofloxacin hydrochloride eye drops or tobramycin eye drops. As the condition is contagious, strict isolation measures are essential throughout treatment and recovery to prevent transmission. Additionally, patients should use separate washbasins and towels, avoid sharing these items, and always wash their face and hands with running water—practices that effectively reduce the risk of infection.

　　In daily life, maintain a balanced diet: avoid spicy or irritating foods, overeating, and staying up late. We hope this information proves helpful.
