I'm guessing your professor decided the ideal vintage point is the back of the room with all the immature guys? I don't know what to suggest beyond that, maybe just focus on people's noses instead of their eyes. That's what I do, usually because it's so close that people can hardly tell.
Ten points for Gryffindor! For some reason he seems to like them, even though you can tell he thinks they're a bunch of immature idiots.
Looking at noses, that's a good suggestion actually. Now, if only someone in my class had a nose like Richard Armitage...
