Babies whose heritage is dark-skinned are usually born with brown eyes, whereas Caucasian newborns tend to be born with blue or gray eyes. Since melanocytes respond to light, at birth a baby may have eyes that appear gray or blue mostly due to the lack of pigment and because he's been in a dark womb up until now.
Well, because all babies are born with blue eyes, right? Wrong. Feast your baby blues upon this fun fact: Worldwide, more newborns have brown eyes than blue. And while it's true that many babies have blue or gray eyes at first, it's important to know that eye color can change for months after birth.
Your child's newborn eye color may be blue, but that doesn't mean it'll necessarily stay that way. “Babies' eyes tend to change color sometime between 6 and 12 months, but it can take as long as three years until you see the true color of what their eyes are going to be,” says Barbara Cohlan, MD, a neonatologist at St.
Just don't expect brown eyes to revert to blue — dark eyes tend to stay dark for most babies. Black, Indigenous and People of Color (BIPOC) infants are more likely to be born with dark, usually brown, eyes, though the shade may change slightly during the first year.
This is because melanin, the pigment that determines your baby's eye color, increases over the first year of life. Eye color is determined by genetics, but it's not as easy as just looking at the parents' eye colors. Even if both parents have brown eyes, it's possible for their child to end up with green or blue eyes.
Two blue-eyed parents are very likely to have a blue-eyed child, but it won't happen every single time. Two brown-eyed parents are likely (but not guaranteed) to have a child with brown eyes. If you notice one of the grandparents has blue eyes, the chances of having a blue-eyed baby go up a bit.
Look at baby's eye from the side to eliminate any light reflecting off the iris. If there are flecks of gold in the blue of the eye, your baby's eyes will likely change to either green or brown as they grow. If there are minimal or no flecks of gold, it's less likely your baby's eye color will change much.
Predicting when your child's eyes will stop changing color can vary. “The range of time when a baby will develop their 'true' eye color varies, but it usually happens between six and nine months of age,” Dr. Zepeda says.
Their basic eye color—blue, brown, green, or hazel—should be evident by about 9 months old. However, eye color can continue to shift and refine until around age 6. A newborn's eye color is based on genetics. Genes trigger the production and distribution of pigments.
Eye color at birth
The more melanin you have, the darker your eyes, hair, and skin are. Melanocytes respond to light, and since newborns have spent the past several months in the womb, they haven't been exposed to much light to trigger melanin production, says Dr.
Since melanocytes respond to light, at birth a baby may have eyes that appear gray or blue mostly due to the lack of pigment and because he's been in a dark womb up until now. As he's exposed to more light, over time (even several years) his eye color can change.
And what your baby eats or does, and how much you expose them to light, doesn't matter either. It's all up to genetics and nothing more. That said, if your baby was born with brown eyes, it means they already have the amount of melanin assigned by their genetic code, so their eye color won't change.
Newborn iris color at birth is brown in 63.0% (121/192) of infants, blue in 20.8% (40/192) of infants, green/hazel in 5.7% (11/192) of infants, indeterminate in 9.9% (19/192) of infants and partially heterochromic in 0.5% (1/192) of infants.
Most babies in the United States are born with blue eyes. Interestingly, only 1 in 5 Caucasian adults grow up to have baby blues. So, why are babies born with blue eyes? It has to do with the amount of melanin they have and how much it increases after birth.
Each parent will pass one copy of their eye color gene to their child. In this case, the mom will always pass B and the dad will always pass b. This means all of their kids will be Bb and have brown eyes. Each child will show the mom's dominant trait.
In as much as 15 percent of the white population (or people who tend to have lighter eye colors), eye color changes with age. People who had deep brown eyes during their youth and adulthood may experience a lightening of their eye pigment as they enter middle age, giving them hazel eyes.
If both the parents have hazel eyes, there are 99% chances that the baby will also have hazel eyes. If both the parents have brown eyes, there is a 75% chance that their child will have brown eyes. If both the parents have green eyes, there are 99% chances that the baby will also have green eyes.

The first 6–9 months is generally when you will see the most changes in your baby's eye color. Due to the production of melanin, their eyes may begin to darken. You likely won't notice it all of a sudden; it will often appear fairly gradually. At 12 months, many babies have their 'final' eye color.
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
As you grow up, the melanin level increases around your pupil, making the eye darker. However, 10-15% of Caucasian eyes change to a lighter color as they age, as pigment in the iris changes or degrades.
Two brown-eyed parents are likely to have a brown-eyed child, but could potentially have a child with blue, green or hazel eyes, depending on the combination of genes from each parent.
They got lighter in his first year and then, very oddly, aged about 2-3 years old they changed to greeny-blue like my DH's! DD had grey-blue eyes at birth, and they gradually went much greyer, just like Miaow's DD. Even at nearly 3 they are still changing.
All men inherit a Y chromosome from their father, which means all traits that are only found on the Y chromosome come from dad, not mom. The Supporting Evidence: Y-linked traits follow a clear paternal lineage.
Unlike nuclear DNA, which comes from both parents, mitochondrial DNA comes only from the mother.
