Understanding Conjunctivitis (Pink Eye)
Viral conjunctivitis is the most common type — it is very contagious and usually runs its course in one to two weeks. Bacterial conjunctivitis often causes thick yellow or green discharge and responds to antibiotic drops. Allergic conjunctivitis causes itching in both eyes and is not contagious.
Common symptoms
- Pink or red eye
- Watery, sticky, or crusty discharge
- Itching or burning
- Eyelids stuck together in the morning
When to seek care right away
Eye pain, light sensitivity, reduced vision, or pink eye in a contact lens wearer or newborn needs prompt evaluation — these can signal a more serious infection.

Frequently asked questions
Do I need antibiotics for pink eye?
Only if it is bacterial. Antibiotics don't help viral or allergic conjunctivitis, which is why an accurate diagnosis matters.
