Eye Colors, Brown

Each of the various eye colors show something about us.

Brown is the most common eye color in the world, because it is caused by a dominant gene. Brown eyes contain large amounts of melanin, a pigment that also causes skin to darken in the sun. If you are lucky enough to have brown eyes, you are much less likely to develop melanoma skin cancer than those with less melanin and those with fairer coloring.

There is a common myth that people with brown eyes are very confident, but it is not always true, as eye color does not determine confidence.

Very dark eyes are sometimes mistaken for being black, but truly black eyes only exist in fiction. Those people who do have incredibly dark brown, almost black, eyes share many of the same traits as those with a lighter shade of brown.
It is very uncommon to find people with brown eyes in some parts of the world, especially Iceland and other parts of Scandinavia. Conversely, brown eyes are everywhere in Africa and Asia.

Technically in the brown eye family, amber eyes are of a solid color and have a strong yellowish/golden and russet/coppery tint from the yellow colored pigment lipochrome in the iris (which is also found in green eyes). Amber eyes should not be confused with hazel eyes; although hazel eyes may contain specks of amber or gold, they usually tend to comprise many other colors, including green, brown and orange. Amber eyes are very rare worldwide, and are most common in Asia and South American countries. Amber eye color can range from golden yellow to a more copper tone. There is a new laser treatment undergoing human testing in Costa Rica that turns brown eyes blue. Reminds me of a song LINK.
