Hazel eyes are a multi-hued iris color that typically has a golden-brown base and changes in color tone to green, amber, or gray as the lighting conditions change. This dynamic color change is due to the unique interaction between the moderate concentration of melanin in the iris and the scattering of light.
Only about 5% of the world’s population has true hazel eyes. The rarity is due to the specific combination of OCA2 and HERC2 genes. The proportion is slightly higher in mixed ethnic groups, such as those of Southern European and Latino descent. However, it is much lower than the proportion of common brown or blue eyes.
How do hazel eyes develop?
The formation of hazel eyes is mainly related to the amount and distribution of melanin in the iris: less melanin than brown eyes, but more than blue/green eyes. This moderate amount of pigment gives the eyes a mixed hue of brown, green, and gold. At the same time, the structure of the iris causes light to scatter, further affecting the final color depth and variation.
How are hazel eyes inherited?
Hazel eyes are inherited by multiple genes and are an incomplete dominant trait. When one parent carries a gene for dark eyes (such as brown) and the other carries a gene for light eyes (such as blue), the offspring may inherit an intermediate trait, resulting in hazel eyes with a moderate pigment content. This inheritance pattern makes hazel eyes more common in mixed-race offspring.
What are the types of hazel eyes?
Greenish Hazel
This type looks greener and may have a noticeable green ring around the outside of the iris, with a small amount of brown or gold near the pupil. The green will stand out more in different lighting.
Amber Hazel
This type is warmer and may contain more flecks of gold, amber, or copper, giving it an overall warm, brownish-yellow hue, but it differs from pure brown.
Brownish Hazel
This type may contain more brown, but there may still be flecks or rings of green, gold, or other colors around the pupil or around the edge of the iris, making it look more layered and varied than pure brown eyes.
Gray Hazel
This type of eye will display a unique blend of gray, green, and brown tones. This type of hazel eye may display different dominant tones in various lighting conditions, creating the illusion of a “color change” without actually altering the eye color.
