Batman Legends of the Dark Knight #158 page 21 Blink

The character Blink is also Lee Hyland (like that first name). From DC database: Hyland doesn't have any eyes of his own. He depends on others, like his seeing eye dog Charlie, for sight. He can't control whose eyes he sees through. Sometimes he can see through other peoples eyes when the person he's using touches somebody else, other times he'll lose somebody's sight if somebody else accidentally touches him. Originally, he was a thief who used his power to steal people's bank account numbers without them realizing. However, after one person he was robbing turned out to be a murderer, Blink attempted to spring into action to save the man's victim, only to get caught at the scene of the crime himself.[1] Clearing his name with Batman, Blink and the dark knight worked together to uncover a conspiracy of people filming and selling the murders of women in Gotham. Once the mystery was solved, Batman let Blink go, encouraging him to give up his life as a thief.
