People say that your eyes are the windows to your soul. But what does that mean about eye color? While some people may think that your eye color may influence your personality, there is no scientific data to back that up. However, there is some science behind your eye color. Why is it colored, and why is it your specific color? And can your eye color actually mean anything?
Colored By Chromosomes
While we do know that the color of your iris is determined mostly from your genetic makeup, so much about the science of eye color is still not understood. While most children learn in school that blue eyes are a recessive trait and brown eyes are a dominant trait, this is not entirely true. It is possible for two brown-eyed parents to have a blue-eyed child—just as it is for two blue-eyed parents to have a brown-eyed child (although the latter is much less likely).
Although we are starting to understand the genetic science behind the most common eye colors, colors such as gray, hazel, and other combinations are still shrouded in chromosomal mystery. This is not surprisingly, though, as there are as many as 15 different genes that have been linked to determining eye color in humans.
Let There Be Light
Lighting can also affect the color of your eyes. This is because light scatters once it is in the eye, and it will then pick up a different frequency, similar to how the sky and water appear blue even though water and air are both clear and colorless. This light, combined with the genetic pigmentation of the iris, causes the color that your eyes currently appear to be.
Can Your Eyes Change Color?
Most Caucasian babies are born with light eyes (usually blue or gray) that will often darken before the age of one as the eyes develop and begin to produce melanin. While these changes usually stop, they can pick back up again during intense hormonal periods, such as puberty or pregnancy.
What Do Your Eyes Say About You?
While your eye color might not say much about your personality, it can say quite a bit about your health. You should be more concerned about age-related macular degeneration if you have lighter eyes, while dark brown-eyed people are more at risk for cataracts. Also watch out for different-colored rings around the iris or color outside the iris, as these may by symptoms of a more serious disease.
