Painful Red Eye: When Is It an Emergency?

Overview

Redness often follows irritation or minor surface problems, but redness accompanied by significant pain deserves a different level of attention. Any change in vision is a warning sign.

How should results or symptoms be assessed?

Contact lens wearers may develop corneal infections; inflammation with light sensitivity and certain pressure problems also require prompt examination. A photograph alone is not enough.

Practical next steps

Stop wearing contact lenses, avoid rubbing the eye and do not start steroid eye drops without medical advice. Explain any trauma, pain and vision change.

When is medical help needed?

Sudden vision loss, severe pain, photophobia, injury or nausea with a red eye needs emergency eye care.
