Episode Details

What is the rarest eye color in the world? Dr. Joseph Allen ranks nine eye-color appearances from the most common to the rarest while explaining the genetics, pigments and medical conditions that can influence how the eyes look.

On the Doctor Eye Health Podcast, discover why brown is the world’s most common eye color, why blue eyes do not contain blue pigment and what makes green, gray, amber and hazel eyes less common.

Dr. Allen explains how melanin, collagen and light scattering create different eye colors. He also explores why albinism can make eyes appear violet, pink or red and why aniridia may create the appearance of completely black eyes.

You will also learn how unusual changes in eye color may be connected to conditions such as Wilson disease. Eye-color percentages are estimates and may vary among populations and research sources.

Key Takeaways

🔹 Brown is the most common eye color worldwide because brown eyes contain more melanin within the iris.

🔹 Blue eyes do not contain blue pigment. Their appearance results from light scattering through collagen fibers in an iris with lower levels of melanin.

🔹 Green, gray and amber eyes result from different amounts and combinations of melanin, collagen and reflected light.

🔹 Violet, pink, red or black eye appearances may be associated with conditions such as albinism or aniridia rather than a distinct natural iris pigment.
