Brown Eyes
The iris is the colored part of the eye. Moreover, the color is caused by a pigment known as melanin, which is also responsible for skin color. Medical experts suggest that everyone had brown eyes when no climate existed and the weather was always sunny.
The iris was dark in color, which protected the eyes from being injured by UV rays and harsh sunshine.
According to estimates, 55 to 79% of people worldwide have brown eyes. Dark brown eyes are familiar in Africa, East Asia, and Southeast Asia, whereas light brown eyes are more common in West Asia, America, and Europe.
What Causes Brown Eyes?
The eye color is an inherited attribute because you cannot tell if your parents have the same eye color as their child. In reality, the color of your eyes is influenced by up to 16 genes. As a result, there is a good likelihood that children in the same family have various eye colors.
The eye color genes are involved in transporting, storing, and generating melanin (the pigment responsible for eye color).
Those with less melanin in their iris have blue eyes, whereas those with more melanin have green, hazel, or light eyes. However, when melanin levels are intense, the color of the eye turns dark brown.
What is the significance of brown eyes?
Brown eyes not only have the advantage that they offer a certain level of protection against various diseases due to their high melanin content. Brown eyes also have advantages in interpersonal relationships because, according to a Czech study, many people find brown eyes to be particularly trustworthy.
Character traits such as loyalty, passion, and emotionality are often attributed to people with brown eyes. However, how much of this is true is not known.
People with brown eyes are also less likely to suffer from alcohol addiction. Vermont researchers found that people with blue, gray, or green eyes make up a large proportion of those suffering from such addictions. However, people with gray eyes, for example, can tolerate more alcohol than people with brown eyes.
In addition, a study from London suggests that people with light eyes are more likely to suffer from noise-induced damage to their ears. The more significant amount of melanin in brown eyes is also intended to protect against this damage.
So, your eye color protects your eyes and ears. However, it does not impact your eyesight because, so far, scientists have not been able to determine a connection between eye color and vision.
Personality Traits Associated With Brown Eyes
According to Ramani Darvaushla, Ph.D., a licensed psychologist and professor of psychology, “Brown eyes are more common, so folks with dark eyes may have a sense of ‘belonging’ or fitting in, and brown eyes are more likely to originate from countries where a quality like agreeableness is more culturally and societally prized than those with blue eyes.”
The most common characteristic linked with brown-eyed people was intelligence, followed by trustworthiness and kindness.
Some studies also found that people with brown eyes make more eye contact than those with other eye colors.
