Polycoria: Your pupil is a round hole that gets bigger as light fades and smaller as light brightens. It’s rare, but some people have more than one working pupil in a single eye. It isn’t clear what causes polycoria, but there may be a link to conditions like glaucoma and cataracts. Not everyone needs treatment, but surgery can restore dimmed vision.

Heterochromia: Your irises are the colored part of each eye. Sometimes they’re a different color from one another. Or one iris might contain different colors.  If you’re born with it, you probably won’t have other symptoms or need treatment. Sometimes it’s a sign of a rare condition you get from your parents at birth. An injury or disease can cause it later in life.
