We usually hear that the eyes are the windows to the soul and that their colors are the expressions of the soul. Of course, we also know that these isn’t the case from the scientific point of view. Here then are the facts and fiction about eyes and their colors, which can be useful in good eye health care.
The Fact: Melanin Determines the Color
The color of your eyes is a product of your genes that, in turn, will be affected by your race. But it’s largely determined by the amount of melanin, a pigment, in your irises (i.e., the colored part of your eyes). The more melanin in your irises, the darker colored your eyes will be.
Thus, if you have grey, blue or green eyes, then your irises have lesser melanin in them. In contrast, people with nearly- black, brown and hazel eyes have higher melanin content in their irises.
Did you know that brown eyes are the most common color in the world? You will find plenty of shades of brown, too, from dark brown to light hazel, even amber.
Blue and gray are the next most common eye colors while green is the rarest color. Of course, you will also find dozens of hues in blues, grays and greens – truly, it’s a wonderful world because of it.
But melanin isn’t just about color. The pigment also protects our eyes from the harmful effects of the sun’s ultraviolet rays. The higher the pigment levels, the greater the protection but everybody’s well-advised to wear protective sunglasses when venturing outdoors.
You can ask your eye doctor at Pearle Vision about protective sunglasses for every season. Your sunglasses in summer should ideally be different in winter because of the differences in conditions.
The Fact: Eye Color Can Change
Newborn babies usually don’t have melanin in their irises. Thus, their eye colors may be nearly colorless or blue – at least for Caucasians. But as they age, their melanin levels also increase and by the age of three, their true eye color will be evident.
But eye color can also change because of age, trauma and disease. For example, prolonged sun exposure can lighten the color of eyes from dark to medium brown.
The Fiction: Eye Color Superstitions
Many people also believe that a person’s eye color is a manifestation of his interests, personality, and talents, even of his destiny in life. For example, green-eyed people are supposed to have sharp minds while hazel-eyed persons have passionate souls. But there are no scientific evidence to prove it although it’s a fun way to pass the time.
In the end, the most important thing is your commitment to ensuring good eye health all the days of your life.
