Is it possible to have two different eye colors? Yes, it is possible for a person to have two different eye colors, a condition known as heterochromia. This fascinating phenomenon can occur due to genetic variations or other factors and can result in strikingly unique and beautiful eye appearances.
What Causes Heterochromia?
Heterochromia can be caused by various factors, including genetics, disease, or injury. It is often inherited, but it can also develop later in life. Here are the main types of heterochromia:
- Complete Heterochromia: Each eye has a completely different color.
- Sectoral (or Partial) Heterochromia: A segment of one eye is a different color from the rest.
- Central Heterochromia: The inner ring of the iris is a different color than the outer ring.
Genetic Factors
Genetic heterochromia is usually present from birth. It can be linked to certain genetic conditions, such as Waardenburg syndrome or Horner’s syndrome. These conditions can affect pigmentation and lead to variations in eye color.
Acquired Heterochromia
Acquired heterochromia can occur due to injury, inflammation, or diseases affecting the eye. Conditions like glaucoma or the use of certain medications can also alter eye color over time.
How Common is Heterochromia?
Heterochromia is relatively rare, affecting about 1% of the population. It is more commonly seen in certain animals, such as dogs and cats, particularly in breeds like Siberian Huskies and Turkish Vans.
Can Heterochromia Affect Vision?
Generally, heterochromia does not affect vision. Most people with this condition have normal eyesight. However, if heterochromia is caused by an underlying health issue, it is important to monitor and address any associated symptoms.
Famous People with Heterochromia
Several well-known individuals have heterochromia, adding to their distinctive appearances:
- David Bowie: Often mistaken for heterochromia, Bowie actually had a condition called anisocoria, where one pupil is larger than the other, giving the illusion of different eye colors.
- Kate Bosworth: The actress has sectoral heterochromia, with one eye partially blue and partially hazel.
- Mila Kunis: Known for having one eye green and the other brown, Kunis has complete heterochromia.
Is Heterochromia Hereditary?
Heterochromia can be hereditary, especially when linked to genetic conditions. If a family member has heterochromia, there is a possibility it can be passed down to future generations. However, it can also occur spontaneously without a family history.

Can Heterochromia Develop Later in Life?
Yes, heterochromia can develop later in life due to injury, illness, or the use of certain medications. If you notice a change in your eye color, it is advisable to consult an eye specialist to rule out any underlying conditions.
Are There Treatments for Heterochromia?
There is no treatment necessary for heterochromia itself unless it is caused by an underlying condition that requires medical attention. If heterochromia affects a person cosmetically, colored contact lenses can be used to create a uniform eye color.
Is Heterochromia More Common in Certain Ethnicities?
Heterochromia can occur in any ethnicity, though it is rare across all groups. The genetic basis for heterochromia does not favor any particular ethnicity.
Can Heterochromia be a Sign of Disease?
While heterochromia is often harmless, it can sometimes indicate an underlying health issue. Conditions such as Fuchs’ heterochromic iridocyclitis or Horner’s syndrome may cause changes in eye color, necessitating medical evaluation.
How is Heterochromia Diagnosed?
An eye specialist can diagnose heterochromia through a comprehensive eye examination. They will assess the eye’s appearance, check for any underlying conditions, and determine if further tests are needed.
Conclusion
Heterochromia is a unique and intriguing condition that can result in stunning eye color variations. While it is often harmless, it is important to be aware of any changes in eye color, especially if they occur suddenly. If you have concerns about heterochromia or notice changes in your eye color, consulting with an eye care professional is a valuable next step.
