Conjunctivitis is a common, usually mild eye infection or allergy causing redness, watering and discharge. Most viral cases clear on their own, and good hygiene stops it spreading.
Clean the eyes gently with cooled boiled water; use cold compresses
Wash hands often; do not share towels or pillows
Allergic type: antihistamine or anti-allergy eye drops
Bacterial type (thick pus): may need antibiotic eye drops
Avoid contact lenses and eye make-up until it clears
When to see a doctor urgently
Eye pain, reduced vision, or light sensitivity (not simple conjunctivitis)
A red, painful eye in a contact-lens wearer
A newborn with red, discharging eyes (urgent)
No improvement in a week
Very contagious — mind hygiene. Viral and bacterial conjunctivitis spread easily, so hand hygiene matters. Pain, vision change or a painful contact-lens wearer’s eye needs urgent review. MedDroid gives general information, not a diagnosis.
Frequently asked questions
How long does pink eye last?
Viral conjunctivitis usually clears in 1–2 weeks; allergic settles when the trigger is removed; bacterial improves within days of antibiotic drops if needed.
Is conjunctivitis contagious?
Viral and bacterial types are very contagious. Wash hands often, avoid touching the eyes, and do not share towels until it clears.
Do I need antibiotic drops for pink eye?
Most cases are viral and clear on their own. Antibiotic drops are only for bacterial conjunctivitis (thick pus) as advised by a doctor.
