What is the name for two differently colored eyes or irises?

Heterochromia is the term used to describe a condition where an individual has two different colored eyes or irises. This can occur due to various reasons, including genetics, injury, or certain medical conditions. The condition is relatively rare and can manifest in complete heterochromia, where each eye is entirely different in color, or sectoral heterochromia, where a portion of one eye differs in color from the rest.

Cataract refers to the clouding of the lens in the eye, which affects vision but does not pertain to the coloration of the irises. Aniridia is the absence of an iris altogether, and low vision patient refers to individuals who have a significant visual impairment that cannot be corrected with standard glasses or surgery. These terms do not relate to the condition of having differently colored eyes.
