I have never heard of sclerology. What is it?

Sclerology is the art and science of observing the markings of the sclera, or the white of the eye. Whereas iridology is about 80% constitutional and inherent potential, the sclera will reveal actual signs of compromised health and show its origin, progression, current status, and healing. It will indicate the health history, and even show health challenges before they have manifested symptomatically or are clinically diagnosable.
