Inflammation or infection of the eye's surface, often called "pink eye" — usually mild and treatable, but spreads easily.
Conjunctivitis — inflammation of the thin membrane covering the white of the eye — is one of the most common eye complaints we see. It can be caused by a virus, bacteria, or an allergic reaction, and while it looks alarming with redness and discharge, most cases are mild and clear up within one to two weeks.
Viral conjunctivitis often accompanies a cold and spreads easily through contact with contaminated hands or surfaces. Bacterial conjunctivitis produces thicker, more persistent discharge, while allergic conjunctivitis tends to affect both eyes at once and comes with itching rather than discharge.
Viral conjunctivitis usually resolves on its own, while bacterial cases respond well to antibiotic eye drops once identified. Allergic conjunctivitis is managed by identifying and reducing exposure to the trigger, alongside antihistamine drops where needed — which is why an accurate diagnosis of the type involved matters before starting any treatment.
See our clinicians if: vision changes, pain is significant, or symptoms don't improve within a few days — this helps rule out causes needing more than home care.
