When to get urgent help

  • Discharge with eye pain, blurred vision or light sensitivity
  • A red, discharging eye in a contact lens wearer
  • Discharge in a newborn baby
  • Discharge with marked swelling and redness of the eyelid or around the eye

Common causes

Discharge usually comes from infection or inflammation of the surface of the eye or the eyelids.

Conjunctivitis Watery or sticky discharge with redness; often both eyes. Blepharitis Crusty, flaky eyelids and discharge that is worse on waking. Stye A tender lump on the eyelid that can weep or crust. Dry eye Reflex watering and stringy mucus from a dry, irritated surface.

Types of pink eye

Viral conjunctivitis Very contagious watery pink eye, often after a cold; antibiotics do not help — hygiene and time are the main treatment. Bacterial conjunctivitis Sticky yellow-green discharge and glued lids, often needing antibiotic drops after assessment; more urgent in babies and contact-lens wearers. Eye allergies Itchy, red, watery eyes from pollen, dust or pets; seasonal peaks in spring and summer respond well to trigger avoidance and allergy drops.

What can help

  • Gently clean the lids and lashes with cooled boiled water or a clean cloth
  • Wash your hands often and avoid sharing towels to prevent spread
  • Stop wearing contact lenses until the eye is better, and seek advice

Frequently asked questions

What causes sticky eye discharge?

The most common causes are conjunctivitis and eyelid inflammation such as blepharitis. Both usually settle with eyelid hygiene, though a painful eye with vision changes needs urgent care.

Is yellow or green eye discharge serious?

Thick yellow or green discharge often points to a bacterial conjunctivitis, which is usually minor. Seek urgent care if there is eye pain, blurred vision, or you wear contact lenses.

How do I clean away eye discharge?

Use a clean cloth or cotton pad with cooled boiled water, wiping gently from the inner to outer corner, and use a fresh pad for each eye to avoid spreading infection.
