Aside from their blue eyes, all blue-eyed persons have one characteristic.
It is the world’s second most popular eye color, with origins estimated to be between 6,000 and 10,000 years ago.
The widespread iris coloration appears to be the result of a genetic mutation, as all humans originally had brown eyes of varying tints.
There are many additional intriguing facts regarding blue-eyed folks.
For example, they are more sensitive to light; having more melanin in the iris implies having more protection in the back of the eye from UV radiation and blue light damage, according to Auckland Eye.
People with blue eyes have less melanin than other colors, hence photophobia (abnormal sensitivity to light) is more common.
While this may sound bad, there are numerous benefits to having blue eyes.
According to the Daily Mail, a study conducted by Louisville University professor Joanna Rowe discovered that persons with this eye hue are more likely to be better strategic thinkers.
