Is it possible to have two different eye colors? Yes, having two different eye colors is a condition known as heterochromia. It occurs when there is a difference in the coloration of the iris. While often a genetic trait, heterochromia can also result from injury or disease. This fascinating condition can manifest in several distinct forms.

What Causes Heterochromia?

Heterochromia is primarily caused by variations in the distribution of melanin, the pigment responsible for eye color. The condition can be categorized into three main types:

1. Complete Heterochromia: One iris is a completely different color from the other. For example, one eye may be blue, and the other brown.

2. Sectoral Heterochromia: A single iris contains two different colors. This can appear as a segment or wedge of a different color.

3. Central Heterochromia: The iris has a different color near the pupil compared to the outer edge. This often results in a "halo" effect.

Genetic and Acquired Causes

• Genetic Factors: Often, heterochromia is inherited and poses no health risks. Conditions like Waardenburg syndrome or Horner’s syndrome can also cause heterochromia.

• Acquired Causes: Eye injury, certain medications, or diseases such as glaucoma can lead to changes in eye color. Inflammation or bleeding within the eye might also result in heterochromia.

How Common is Heterochromia?

Heterochromia is relatively rare in humans but more common in animals like cats, dogs, and horses. In humans, it affects less than 1% of the population. While rare, it is generally harmless and often considered a unique and striking feature.

Examples of Celebrities with Heterochromia

• Kate Bosworth: Known for her striking eyes, Kate has sectoral heterochromia, with one eye partially blue and partially hazel.

• Mila Kunis: She experienced heterochromia due to chronic iritis, resulting in one eye being brown and the other green.

Is Heterochromia a Health Concern?

In most cases, heterochromia is benign and does not impact vision or health. However, if heterochromia develops suddenly or is associated with other symptoms, it is important to seek medical advice. This can help rule out underlying conditions that might require attention.

When to Consult a Doctor

• Sudden change in eye color
• Accompanying eye pain or vision changes
• Eye injury or trauma
