The white part of the eye is called the Sclera. You don't normally see much of this on a horse unless it is an Appaloosa or has a large blaze(a horse that has the white of the eye showing frequently are usually considered to be spooky) FYI Horses can sometimes have a black sclera. If the spots are greyish/blue it can also be something called Scleral melanocytosis, which is not harmful.
In my opinion, a horse is the animal to have. Eleven-hundred pounds of raw muscle, power, grace, and sweat between your legs - it's something you just can't get from a pet hamster.
