Kate Bosworth Has Two Different-Colored Eyes, and They're so Stunning

A beautiful eye color is striking on anyone, but what about two different eye colors? Heterochromia is when a person’s irises, the pigmented portion around the pupil, are different colors or partially different colors. According to the American Academy of Ophthalmology, several different types exist including having two different colored irises, an iris that’s partially a different color or segmented, or an inner ring around the iris that’s different from the color of the outer iris. It’s often subtle but also may be quite noticeable and incredibly beautiful!
