  Even before I read the answer, I'd like to give it a try. Sunday should be the best time to do it. Will end up eating hours, I know.
  
  But good that you're going deeper in the puzzle.

  i still cant get it .if a person sees another person who is blue eyed and if he does not leave he may think that he has not left the next day because he did not realise it.he cannot think the the first hypothesis to be wrong.

  Oh nice that u'r taking ur effort to decode it. But let me warn u, the solution is pretty hard!
  
  @eelectrichuman
  In ur doubt, think why didn't he realize it.
  If person A had red eye and person B see it, he would realize his eye colour immediately(ie, blue).
  But person B still doesn't realize it and leave, only means that person A is also having blue eye, which made B unsure whether he is having blue eye. See this scenario in the viewpoint of A.

  if I can expand solution by one level only... let's c there are only 3 blue-eyes people.. on first day, all of them would see other 2 as blue-eye and they would think that other leave but if no-one from those 2 blue-eye leaves on first day... they would think that they both (which one can see) would leave tonight and if they both did not leave that night.. then on third day they all realize that they are having Blue-eyes and leave...
  
  So Logically it is right...
  
  I don't think they would require any other information from GURU...
