Typically, a person’s eye color becomes permanent about three years after birth. So regardless of how much or little light exposure you have, your genes determine how light or dark your eye color is. Or maybe your eyes didn’t darken much and they stayed light blue. But depending on your genetics, your eyes could have turned dark brown. The longer your eyes were exposed to light, the more melanin pigments your irises produced. Your eye color, however, probably took a little more time to develop. For example, if your parents have darker skin and hair, then you likely had those same dark pigments in your skin and hair when you were born.

However, genetics also factor into skin, eye, and hair color. Since babies don’t receive a lot of light exposure, they tend to have fairer skin, hair, and eyes than adults.

Once your body became exposed to light, it started to produce melanin, which in turn changed the color of your hair, skin, and eyes. Melanin is a pigment that gives your eyes, skin, and hair their color. Babies’ eyes display this color because their bodies and eyes contain low levels of melanin. When you were born, you likely had blue eyes. Where does eye color come from, and how can it change? Does this change happen naturally or do outside factors influence how your eye color appears? Below, we’ll answer these questions and others as we explain why and how eye color changes. But when your eyes appear to change color suddenly, or even over time, the wonder that is eye color becomes significantly more intriguing. Have you ever looked in the mirror and noticed that your eye color looks different? Did your eyes appear a darker brown yesterday but today they look lighter? Eye color in and of itself is a fascinating phenomenon.
