A COMBINATION OF HYALURONIC ACID OR A SALT THEREOF AND FLAVIN ADENINE DINUCLEOTIDE OR A SALT THEREOF CAN BE AN INHIBITOR FOR CORNEAL EPITHELIAL CELL DEATH INDUCED BY ULTRAVIOLET IRRADIATION AND/OR DRYNESS BECAUSE IT SIGNIFICANTLY INHIBITS THE DECLINE OF THE NUMBER OF LIVING CELLS IN CORNEAL EPITHELIAL CELLS INDUCED BY ULTRAVIOLET IRRADIATION OR DRYNESS.
