Why is my iguana's eye look strange?

I had just bought a new baby iguana yesturday and one of it's eyes looks like it's permenatly looking back while the other is normally looking straight, also the one that is locked looking back is squinting, did it get injured? And is it not fixable? Will it heal by itself? The pet shop had him in an aquarim with a dragon/iguana looking lizard that was twice the size bigger then him and was moving around viciously, and a camelon and frog could one of these might have hurt him?
