Anisocoria

Anisocoria is a rare medical condition characterized by different-sized pupils. You may have heard of this condition from the iconic singer David Bowie, who has made this feature one of his unique trademarks. Bowie had both anisocoria (unequal size of pupils) and heterochromia (different colors of eyes).

Unlike heterochromia, anisocoria is a more common condition, and in such cases, it doesn’t come along with symptoms or side effects. In fact, twenty percent of the human population have anisocoria to some degree. While it can have various causes, the singer was proud of his oddity and said it was caused by an injury during his teenage years. Well, who would have thought that someone with such an eye condition would become one of today’s most influential singer-songwriters? His career was marked by visual presentation and reinvention, and both his music and stagecraft have impacted the music scene.
