Pink eye, or conjunctivitis, is an inflammation of the conjunctiva, the clear tissue that covers the white part of the eye and lines the inner eyelid. This condition can cause the eyes to appear red or pink, hence the name.
There are three main types of conjunctivitis:
-
Viral Conjunctivitis: Caused by a virus, often linked with cold symptoms. It’s highly contagious and spreads through direct contact with infected fluids or respiratory droplets.
-
Bacterial Conjunctivitis: Caused by bacteria and is also contagious. It usually leads to a thick, yellow or green discharge from the eye.
-
Allergic Conjunctivitis: Triggered by allergens like pollen, dust, or pet dander. This type isn’t contagious but can cause itching, swelling, and watery eyes.
Common symptoms include:
- Redness in one or both eyes
- Itching or watering of the eyes
- Swelling of the eyelids
- A gritty sensation in the eye
- Discharge, often crusting overnight
Treatment depends on the cause:
- Viral: Typically clears up on its own within 1–2 weeks.
- Bacterial: Usually treated with antibiotics (eye drops or ointment).
- Allergic: Managed with antihistamines or allergy medications.
If you think you have pink eye, it’s best to consult a healthcare professional for proper diagnosis and care.
