Pink eye, also called conjunctivitis, is an inflammation or infection of the conjunctiva — the thin, clear tissue that lines the inside of your eyelid and covers the white part of your eye.

When this tissue becomes irritated or infected, blood vessels swell, giving the eye a reddish or pink appearance — hence the name pink eye.

Types of Pink Eye

Viral Conjunctivitis Viruses: Watery discharge, redness, itching, often starts in one eye and spreads. It usually clears up on its own in 7–14 days; use cool compresses and artificial tears to soothe. It is highly contagious.

Bacterial Conjunctivitis: Thick yellow/green discharge, eyelids stuck together, redness. It needs antibiotic eye drops or ointment prescribed by a doctor. It will improve in a few days after treatment begins.

Allergic Conjunctivitis: Itching, tearing, swelling, both eyes affected. Use antihistamine or allergy eye drops; avoid allergens; cool compresses help. This type is not contagious.

Irritant Conjunctivitis: Smoke, chlorine, chemicals, or contact lenses. Redness, burning, watery eyes. Rinse eyes with clean water or saline, avoid irritants, and symptoms should fade once exposure stops.

Home Care Tips

Wash hands frequently — pink eye (especially viral/bacterial) spreads easily.

Don’t share towels, makeup, or pillowcases.

Replace or clean contact lenses and cases properly.

Use cold compresses to reduce irritation and redness.

Avoid touching or rubbing your eyes.

When to See a Doctor?

Contact a healthcare provider if:

Symptoms last more than a few days or worsen.

There’s eye pain, light sensitivity, or blurred vision.

You wear contact lenses and notice redness or discharge.

The discharge becomes thick, yellow/green, or causes eyelids to stick shut.
