19 Facts About Eye Color

Eyes come in various colors

The color of the eyes is determined by the amount and distribution of melanin in the iris. This pigment is responsible for the color of the eyes, with higher levels resulting in darker hues.

Eye color can change over time

Babies are often born with blue or gray eyes, as melanin production in the iris may not be fully developed. As they grow, the eyes may undergo a transformation, and the final color may not be apparent until they are around three years old.

The most common eye color is brown

Brown eyes are the most prevalent eye color worldwide, with a majority of the global population having varying shades of brown eyes.

Blue eyes are the result of a low concentration of melanin

The unique hue of blue eyes is due to low melanin levels in the iris, allowing light to scatter and reflect, resulting in the characteristic blue color.

Green eyes are the rarest eye color

Green eyes are a result of a combination of low melanin levels with the presence of a yellowish pigment called lipochrome. This combination creates the striking green coloration.

Hazel eyes are a blend of colors

Hazel eyes contain a combination of brown and amber with hints of green. The varying concentrations of melanin and the presence of lipochrome contribute to the distinctive appearance of hazel eyes.

The genetics of eye color are complex

Eye color is a polygenic trait, meaning it is influenced by multiple genes. The inheritance of eye color follows a complex pattern, making it challenging to predict the eye color of offspring based solely on the parents' eye colors.

Eye color is linked to ancestry

Certain eye colors are more prevalent in specific ethnic groups. For instance, individuals of European descent are more likely to have blue or green eyes, while those of African or Asian heritage commonly have brown eyes.
