In Oklahoma there is a Jehovah's Witness woman who looks into a person's eyes and can tell what is wrong with a person. She sells herbs and other crack pot medicines to these people after they have been "diagnosed". I watched her in action, she shines a flashlight into your eye to make the pupil small, and then "reads" the colored part of your eye. If this was a good idea, medical doctors would do it. It looked like witch doctor medicine to me.
