When should you see a doctor about eye discharge?

Clear, watery discharge can occur with irritation or allergic conjunctivitis. Sticky or pus-like discharge, eyelids stuck together, and redness may occur with conjunctivitis. A tender bump at the eyelid edge can fit a stye. Symptoms in one eye may spread to the other, while contact lens use can change the level of concern. The appearance of discharge is useful information, but it does not establish the cause by itself.

Wash your hands before and after touching the eye. Gently clean away discharge with clean water and a fresh pad, using a separate pad for each eye. Avoid rubbing, sharing towels, eye cosmetics, and contact lenses until symptoms have settled or a clinician advises otherwise. Do not use leftover antibiotic or steroid eye drops without an examination.

Seek urgent eye care for sudden vision change, severe eye pain, strong light sensitivity, an injury or chemical exposure, a bulging eye, or swelling that spreads around the eye. Contact a clinician promptly if a contact-lens wearer develops pain, redness, or blurred vision.

Ask whether the pattern fits allergic conjunctivitis, conjunctivitis, or a stye; whether testing or prescription drops are needed; and when it is safe to return to contact lenses, swimming, or eye makeup.
