See all replies 2. LilPieceOfMe said:. So cuteeee! But I have very icy blue eyes and one of my sisters has golden eyes I guess of the hazel variety but more gold I asked my mom and she said my sister was born with dark blue eyes and they kept changing and eventually settled a golden color. Both DD and my son were born with blue eyes. Ultimately, eye color depends on the genetic material that each parent contributes and how those genes mix and match together. Most light-skinned babies are born with grayish-blue eyes, while most darker-skinned babies are born with dark brown eyes.
But this color can change once the baby's eyes are exposed to light outside of the womb because the iris the colored ring around the black pupil has color-producing cells in it. Usually, this color-changing process takes around six months. However, sometimes eye color continues to change until the age of three. Eye color is determined by melanocytes, which are cells that secrete the protein melanin. Melanin is what influences skin, hair, and eye color.
The iris contains melanocytes, and these cells respond to light by increasing melanin production, usually over the first year of life. Depending on how much melanin is secreted, your baby's eye color may slowly begin to change after birth. If your baby has blue eyes, their melanocytes are secreting only a little melanin.
If they secrete just a little bit more, your baby's eyes will look green or hazel. If your baby has brown eyes, the melanocytes are secreting a lot of melanin. These genes control for brown or blue and green or hazel.
For years, brown eye color was considered the "dominant" trait, and blue eye color was considered the "recessive" trait. But today, we know that determining eye color is not that simple because eye color is not influenced by just one or two genes. Ultimately, your baby's exact eye color will depend on the combination of these 16 genes that they inherit from both of their parents.
This is why, though rare, two parents with brown eyes can have a baby with blue eyes. Sometimes children are born with irises that do not match in color.
This condition, known as heterochromia, is typically present at birth where it is called congenital heterochromia. But heterochromia can also result from a health condition or trauma. For example, Horner's syndrome, which is a disruption of the nerve pathway from the brain to one side of the face and eye, can cause unexpected changes in eye color.
Waardenburg syndrome is a group of genetic conditions that can also cause changes in eye coloring. Children with this condition often have very pale blue eyes, have one blue eye and one brown eye, or have one eye that segments into two different colors. If you notice any unusual appearance in your baby's eye color, contact your pediatrician. They may refer you to an ophthalmologist. Because there is still a lot that is not understood about the interplay among genes and their role in determining eye color, it is hard to make predictions about what shade your baby's eyes will end up being.
