![]() However, if your eye color has changed suddenly and you noticed a big difference in the color, meet with your eye doctor immediately. Unless you’ve noticed drastic, sudden changes in your eye color, you have no need to worry. Instead, a variety of external factors combined with your genetics determines how your eye color looks on any given day. What Do the Experts Say About Changing Eye Color?Īccording to some eye doctors, your eyes don’t just change color on their own. If you’ve noticed a drastic change in your eye color as an adult, you may need to see an ophthalmologist or optometrist to rule out any possible health risks. Some of these causes can have adverse effects on your ocular and overall health. However, you can acquire heterochromia as an adult from: You might be born with this condition, and if you are, it doesn’t affect your health. Central heterochromia refers to a condition where your iris has two different colored rings. One corner might look green while the rest of the iris looks blue. Partial heterochromia means parts of your irises are different colors. However, a few kinds of this condition exist. Heterochromia refers to a condition where each iris has a different color. If you’ve developed a rare condition called heterochromia, your eyes likely have changed color significantly. Depending on the color you wear, your eyes may appear lighter or darker. If you wear certain colors of clothing, the pigments in your shirt, jacket, tie, or scarf could temporarily change the color of your eyes. This principle applies to eye color as well. When reds and greens are placed together, the reds appear more vibrant while the greens appear more lush. If you think back to your elementary, middle school, high school, or even college art classes, you’ll remember that complementary colors enhance one another. This change is due to the contrast between the black of the pupil and the surrounding iris. On the other hand, when your pupils are smaller, your eye color may appear lighter. For example, if your pupils widen, not as much of your irises are exposed, and the remaining irises look darker. When your pupils shrink or dilate, the color of your eyes may seem to change. ![]() Your pupils’ size can also cause your eyes to change color. Since natural sunlight is often brighter than artificial lights, exposure to it might allow you to see colors in your irises that you couldn’t recognize before. Sunlight can also reveal colors that were already in your eyes. As a result, your eyes might appear a darker shade of brown, blue, green, or gray, depending on your current eye color. Even if your eye color has set, your eye color could slightly change if you expose your eyes to more sunlight. Increased Sun ExposureĪs previously mentioned, exposure to light causes your body to produce more melanin. However, several factors can influence your eye color and whether or not it changes to a different pigment. Once eye color has set, the color usually won’t change. 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.
