Humans have different eye colors. This is usually caused by melanin, which causes them to respond differently to light, glare, or lack of melanin. Blue eyes are the second most common eye color after brown eyes. However, blue eyes are usually considered to make one's appearance more attractive. Blue eyes are claimed to see better in the dark. However, what actually causes eye color to become blue and what is the difference between blue eyes and regular eye color? Read the following article for a more detailed explanation.

People with blue eyes have a slight variation in melanin DNA, indicating that they have the same origin. Blue eyes appeared around 6,000 - 10,000 years ago in Southeast Europe. Genetic mutation causes blue eyes, which are inherited by the next generation.

Meanwhile, people with blue or lighter eyes have less melanin and tend to have better night vision, although they may experience problems with bright light. This is because brighter eyes have a better ability to reflect light compared to darker eyes.
