What determines the color of the eyes, and can it change over time?

In the past, people believed that they could foresee the color of children's eyes by looking at the colors of their parents and grandparents ' eyes

Based on the belief that brown eyes are a dominant trait and blue is a recipe, you can imagine what color the child's eyes would have.

Today, we know that the color of our eyes is not that easy to predict “. While genetics plays a role, the color of the eyes is not the product of a single gene.

There are some genes that contribute to your eye color. The latter is the result of the amount and distribution of melanin in the iris of the eyes (Iris ʹthe color of the eye).

So while two brown-eyed parents are more likely to have a brown-eyed child, the result is not guaranteed, the Web MD writes.

Most people have brown eyes.

Blue-eyed people don't have the melanin in the den, the front layer of iris. The lack of pigment in the eye causes light to spread when it hits, making the iris appear blue.

Green eyes are the rarest. Only about 2% of the world's population have such eyes. The color comes from both the melanoma and the effect of the distribution of light when it becomes visible.

People born with albinism often have little or no melanity in their bodies. As such, they usually have light blue eyes. On rare occasions, they may have clear iris that make their eyes look pink or red.

Can the color of the eyes change?

The color of the eyes can change in infancy. Many babies are born with blue eyes that eventually turn to a different color as the melanoma develops in the den. The color of their eyes generally becomes permanent about their first birthday.

Generally, it is rare for eyes to change color. They may seem to change when the babies expand or shrink, but this is because the pigments in the iris are united or distributed.

In some cases, the color of the eyes may get a little dark during puberty or pregnancy, Annabel quotes.

Health problems such as eye trauma, neurofibromosis, uveit (the condition that causes swelling) and others can change the color of your eyes.
