Sclerology is used alongside Iridology. It is the study of blood vessels in the whites of the eyes and how they relate to a person’s health. Historically both the Native American Indians and Chinese physicians used this method.
Neuro-muscular reflexes from the brain and optic nerve transmit direct information about the blood, lymph and nervous system onto the four main quadrants of the sclera. This can be interpreted and in conjunction with consultation provides a detailed view of the inner condition of the body.
Though disease may take years to develop, changes in the sclera can be observed almost immediately.
We all have an innate awareness of this. When we see someone and glimpse at their eyes, part our impression, good or bad, is taken by the clarity of the whites of their eyes.
