In my honest opinion, I would do one of the following
a) Get use to it. I've grown to like many current friends that had annoying habits that become 2nd nature to me and It turns out to be a good relationship
b) It bugs the hell out of me so much that I don't even want to talk to him
c) Make fun of him and crack jokes about his eye
d) All of the above
The point is, there are many shallow people out there including me. The trick is to separate that shallowness and have compassion towards others. We are all shallow in one way or another so you should learn to live with it ^^.
Well, that was a bit too philosophical even for me LOL
