Whereas Heterochromia (also known as a heterochromia iridis or heterochromia iridium) is is an eye condition in which one iris is a different color from the other (complete heterochromia), Central Heterochromia (also known as Sectoral Heterochromia) is an eye condition in which there are two different colors in the same iris. Central Heterochromia is where the central (pupillary) zone of the iris is a different color than the mid-peripheral (ciliary) zone, and may be linked to above average toxic burden in the body.^[1] In Central Heterochromia both eyes feature a central ring, usually brown/orange/yellow, and a true colored outer ring, The highly pigmented area that appears around the pupil and spreads outwards towards the edge of the iris may not be relevant to iris analysis unless it spills over the collarette. Conditions of gastric sub-acidity and hypochlorhydria may also be indicated. A common sign found in the biliary constitution.^[2] Though not studied widely, Central Heterochromia is the rarest form of Heterochromia.^{[citation needed]}

Eye color is determined primarily by the concentration and distribution of melanin pigment within the iris tissues, Anything affecting those factors may result in a difference of color being observed.^[3]

The human iris can be seen in a number of various colors. There are three true colors in the eyes that determine the outward appearance; brown, yellow, and gray. How much of each color an individual has determines the appearance of his or her eye color.^[4]

Eyes displaying Central Heterochromia are often referred to as "cat eyes" because of the appearance of a multi-colored iris. Central Heterochromia appears to be prevalent in irises containing low amounts of melanin^[1][2].Central Heterochromia does not label an eye as hazel. This is because the outer ring of an eye affected by Central Heterochromia is that iris' true color.

The potential to acquire central heterochromia may be inherited genetically, though Central Heterochromia in itself is the condition where drug and toxic settlements in the body make the iris color appear different from its basic predominant color. These toxic signs that show in the iris indicate the amounts of the toxins the system has failed to eliminate.^[2]
