On the other hand, a multi-year survey of students at Iowa State University found the prevalence of green eyes to be Also, the prevalence of green eyes varies ificantly by geographical region and country, with the greatest concentration in Northern and Central Europe. Genetics play a role in determining eye color. This is because many different genes are involved in the inheritance of eye color, and different interactions and levels of expression of these genes can alter eye color outcomes in children.
The structure within the eye that is responsible for eye color is called the iris — the thin, circular structure that surrounds the pupil. In addition to controlling the size of the pupil and therefore the amount of light that enters the eye, the iris contains pigmented cells that determine eye color. But here's where it gets interesting: Though there are many different eye colors, there are surprisingly few types of eye pigments. In fact, nearly all eye colors are determined by how much brown-colored pigment called melanin is contained in cells in the iris. So how does a brown-colored pigment create green eyes — or blue eyesor hazel eyesor any eye color other than brown?
Differences in eye color are the result of different amounts of melanin pigment granules within cells in the iris called melanocytes. These cells acquire their genetically determined amount of melanin in early childhood, and their melanin content usually remains relatively constant throughout Love blue or green eyes. A person with less melanin in the melanocytes of his or her iris will have a lighter eye color blue or green, for example than a person with a greater concentration of melanin, who will likely have brown eyes. But an additional factor is involved in determining eye color, especially different shades of green eyes and blue eyes.
When light strikes Love blue or green eyes iris and the pigment-containing melanocytes within the iris, this light is scattered and reflected. This phenomenon, called Rayleigh scattering, can produce different reflective colors, depending on the physical structure of the iris and the amount of melanocytes and density of melanin within the melanocytes. Depending on these variables, Rayleigh scattering which is the same phenomenon that makes a cloudless sky appear blue can produce different shades of blue, green, hazel, and so on.
It's also noteworthy that, depending on the structure of the iris and the distribution of melanocytes within it, some eye colors can be difficult to categorize. For example, some "green" eyes may have a crown of hazel or brown near the pupil, making them appear hazel at times and green at other times, depending on lighting, makeup and the color of clothing a person wears. Here are some of the actors, singers and other celebrities who might owe a small part of their appeal to their green eyes:.
