Fluorescein is used in medicine to diagnose corneal ulcers and certain other eye disorders. A solution of the chemical is dripped into the eye, and a type of fluorescent light is shined into it. Ulcerated areas will glow green under the light, which confirms the presence of ulcers and pinpoints their locations.
