Hazel eyes are sometimes mistaken for green or brown eyes. They are not as rare as green eyes, but are rarer than blue eyes. Only about 5 percent of the population worldwide has the hazel eye genetic mutation.

Yes, blue-eyed parents can definitely have a child with brown eyes. Or green or hazel eyes for that matter. This means that if a parent has a brown eye gene, they’ll have brown eyes.

First, the answer is yes to both questions: two blue-eyed parents can produce green or brown-eyed children. However, because many genes are required to make each of the yellow and black pigments, there is a way called genetic compensation to get brown or green eyes from blue-eyed parents.

Why are blue eyes so uncommon any more? Blue eyes are indeed becoming less common in the world. One study showed that about 100 years ago, half of U.S. residents had blue eyes. Another reason blue eyes are declining is because they were at an artificially high level before.

Obviously most blond-haired and blue-eyed people are of European ancestry, particularly Northern Europe. However a single blonde, blue-eyed person may be of Southern Europe such as Italian (Note: 8.2% of Italians are blond-haired). When this trait becomes common, then a Northern European ancestry becomes clear.

Pros and Cons of Each Eye Color Another possible benefit of hazel or brown eyes is that you may be less prone to damage from environmental noise. It is believed that the higher level of melanin may offer protective benefits for the brain’s nerves that may experience damage due to noise.

Here are some of the foods that change your eye color if consumed often:

• – Spinach: It’s richness in iron will make your eyes look younger and shine brighter!

Eye color fully matures in infancy and remains the same for life. But in a small percentage of adults, eye color can naturally become either noticeably darker or lighter with age. What determines eye color is the pigment melanin.

However, when broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world’s population sports melanin-rich eyes.
