Blue. Brown. Green. Hazel. Gray. Everyone’s eyes are a lovely color, and they always match, right? Well, no. Sometimes people have two different color eyes. This phenomenon is called heterochromia, but what, exactly, is it?
The colored part of the eye is called the iris, which squeezes and relaxes to let light through the pupil. Eye color is determined by the amount of melanin in your iris. Melanin is the same pigment that gives your skin color.
Heterochromia is when a person’s irises are different colors. Complete heterochromia is when the irises are two different colors. Partial heterochromia is when parts of the same iris are two different colors. Central heterochromia is when the inner ring of the eye is different from the outer ring.
In many cases, babies are either born with heterochromia, or it develops soon after birth. This is called congenital heterochromia. Usually, they will experience no other health issues. That said, heterochromia can be a symptom of another condition such as Horner’s syndrome, Waardenburg syndrome, and Hirchsprung disease.
People can develop heterochromia later in life, too. Acquired heterochromia can be caused by a number of factors, including an eye injury, eye bleeding, swelling, glaucoma, pigment dispersion syndrome, diabetic eye disease, and eye tumors.
Babies should have their eyes examined to make sure there isn’t an underlying cause of the heterochromia. In most cases they’ll be fine, but parents will still want to have their baby checked to make sure they don’t have a more serious condition.
Adults who find one of their eyes turning a different color should see a doctor to find the cause and develop any necessary treatment plans. If the doctor doesn’t find a serious cause, they may not recommend any treatment.

Your iris can be replaced if it is affected by injury or disease. Your new artificial iris may also change your eye color in the process.
Ptosis or drooping eyelid can cause vision problems and self-confidence issues. Eyelid surgery by a CEENTA oculoplastic surgeon can remedy this condition.
