they could only see things that they have before......i think a blind would just see trails of lights of different colors and shit....they would definately feel good still. that was a fuckin cool quesiton though. they wouldnt see like people and shit that you have to see with your eyes.....orrrr the blind person could see what they pictured people as looking like and other objects they have only become familiar with the texture/feel/smell/taste of or whatever....i dunno man
