CHANGING EYES: A horse’s eyes don’t change. It’s a horse’s body that does the changing. The horse turns his head and shapes up his body so he can see whatever he needs to see. You’d work both sides of your horse so both eyes get used to seeing you, and this way the horse wouldn’t think that you belong just on one side. He would get so he could see you anywhere and it wouldn’t bother him. So long as the horse is feeling of you, then there isn’t a reason for him to be one-sided.
