Yesterday, in the swing park I got chatting to a man who had brought his grandson to play. Turns out the man used to be a professional landscape photographer, who also taught youngsters to photograph. Then last year a virus got in his eye and his vision deteriorated. He can't do his job anymore. He has been told by surgeons that he could get his cornea replaced (using a donated one from a dead person) but there is no guarantee the operation would work. So what would you do....little eyesight/no eyesight/perfect sight?
