We saw a documentary or something about the glasses-and-implant combo. At that time, the resulting image was just a series of dots, which formed shapes. The subject could "see" a line of dots, but they wouldn't know if that line represented the edge of a book or the edge of a building. The subjects were clearly disappointed, even though they had been warned that this was not going to be real vision, they had unrealistic hopes. It was a very interesting program.
