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.
