Heterochromia

Heterochromia is a condition characterized by a difference in coloration of the iris (the colored part of the eye), resulting in variations in pigmentation, causing one eye to be a different color than the other or parts of the same iris to have different colors

There are two primary types of heterochromia: complete heterochromia (where each iris is a distinctly different color) and sectoral or partial heterochromia (where there are variations or spots of different colors within the same iris)

It can be congenital (present at birth) or acquired due to injuries, diseases, or syndromes such as Waardenburg syndrome or Horner syndrome

Heterochromia is generally harmless and does not usually affect vision. However, it can be associated with certain eye conditions or syndromes that may require medical attention

Treatment is often unnecessary unless it's related to an underlying condition. People with heterochromia might use tinted contact lenses for cosmetic purposes
