Eye spy? Only kidding...swimming, music, concert, audio books, dvd's, pub, olympics coverage, surfing the interweb (with appropriate technology e.g. JAWS screen reader)? As staples says how does he entertain himself?
Off topic but I was watching a program about one of the survivors of the Omagh bombing who lost her sight. She was stir frying vegetables for herself including cutting them, frying etc, so I suspect you'd be surprised how much he can do. I know she was in her own home and would have been used to the surroundings...
