Iridology is the analysis of patterns, structures, and colors in the iris to show the health of organs throughout the body. By looking at the iris, an iridologist can see what is happening in different parts of the body without going inside the body.

The iris, which is the part of the eye that shows color, can reveal body strengths and weaknesses, as well as signs of irritation, injury, or deterioration of tissues. Because of this, iridology can be a form of preventative healthcare by showing what is happening in the body before any symptoms appear – it can show tendencies towards a possible disease.

The iris is composed of thousands of nerve endings that are connected to every tissue in the body through the brain and nervous system. An iridologist first examines the iris before consulting an iris chart. An iris chart divides the iris into zones that correspond to specific areas of the body – these areas can include body organs and tissues. Most charts have between 60 and 90 zones.

The iridologist can then look at the iris and iris chart to see which body organs and tissues are weak or strong.
