27) Heterochromia
I Have Complete Heterochromia
In most cases, there is only one eye with one iris and one pupil, while the other eye has a different color. Heterochromia can be found in both eyes at birth or develop over time. It can also occur as a result of an underlying condition, such as diabetes or thyroid disease.
Children who have heterochromia are more likely to have vision problems than those with standard-colored eyes. The most common type of heterochromia is sectoral heterochromia, which occurs when two different colors are present on the same side of the iris.
