rose bengal 

An iodine derivative of fluorescein having vital staining properties but unlike fluorescein it is a true histological stain, which binds strongly and selectively to cellular components. The colour of this stain is red. It has the disadvantage of causing some pain in a good percentage of eyes. It stains dead or degenerated epithelial cells but not normal cells and is used to help in the diagnosis of corneal abrasion, keratitis, keratoconjunctivitis sicca, lagophthalmos, etc. See fluorescein; lissamine green.
