Sore eye. A sore eye is most commonly caused by dryness or irritation which are helped iwth the use of artificial tear drops. Because the surface of the eye is not smooth because of the dryness, this commonly causes a small change in the vision and account for the feeling of imbalance. Also possible is that one eye needs some glasses and the other does not.
