When Do Babies Eyes Change Color? Will They Stay Blue?

You may have heard that babies eyes often change color during the first year of life. Is that true? Find out now.

Find out what determines baby’s eye color (it's not just the parents!), whether all babies are born with blue eyes, plus when do babies eyes change color?

If your baby was born with a full head of hair and piercing blue eyes, it may surprise you to learn that, in a few months time, baby could have no hair and green eyes. Baby changes rapidly in that first year, so if your child was born with those baby blues, you’ll probably wonder will they change color—or will they stay blue? When do babies eyes change color?

When Do Babies Eyes Change Color?

If your child is born with those baby blues, you’ll probably wonder when do babies eyes change color? Will they change color—or will they stay blue? 

It can take as long as 9 to 12 months for your baby’s permanent eye color to be determined and the change is so gradual, you might not even notice it happening. But by baby’s first birthday, you can be pretty sure whatever big eyes are staring down that smash cake are the ones they’ll have for life.

“Though some babies’ eye color changes rapidly with the onset of melanin, most infants undergo significant changes between six and nine months of age. This phenomenal occurrence happens once the iris has stored enough pigment to influence subtle changes like blue to grey, green to hazel, hazel to brown and so on.”(source)

Keep in mind that eye color generally gets darker, not lighter. Your brown-eyed girl isn’t likely to become blue-eyed later in life. But your blue-eyed boy may very well end up with green or even brown eyes.

Curious about baby’s eyesight? See our article on when babies can see.

Can You Tell if Baby’s Eyes Are Going to Change Color?

As noted above, if baby is born with brown eyes, he/she will almost certainly have those brown eyes for life. If baby has blue eyes, this simple (but not foolproof!) trick can help determine whether or not they’ll stay that way. (source)

  1. Look at baby’s eye from the side to eliminate any light reflecting off the iris.
  2. 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.
  3. If there are minimal or no flecks of gold, it’s less likely your baby’s eye color will change much.

Another indicator? If baby’s eyes are clear, bright blue, they are most likely staying blue. If they are a darker, cloudier blue, they are most likely going to change to hazel, brown, or a darker color.

What Color Eyes Will My Baby Have?

There’s no way to know for sure what color eyes your little one will have.

Recent research suggests there’s a lot more than parents’ eye color that affects baby’s eye color, but you can generally expect:

  • Two blue-eyed parents to have a blue-eyed child.
  • Two brown-eyed parents to have a child with brown eyes.

  2. Iridology, the study of the iris to detect a person’s health constitution, can provide a whole new perspective at why a baby’s (and adult) eye color changes and is the way it is. Your iris is actually a bundle of nerve endings that keep a recording of your health. Each color indicates a predisposition for weakness in certain areas like blue eyes are prediaposed to have lymphatic and respiratory weakness and inflammation. Other signs in the iris can indicate more direct issues that have taken place over a life time or are inherited. Pretty cool stuff!!!

  3. My husband and I have brown eyes, my 6 year old has blue eyes, my 3 year old has green eyes, and so far our 4 month old has light blue eyes like his sister. I don’t think they’ll go dark but I am interested to see whether they’ll stay blue or turn green.

  4. First, my own experience with eye color: I had blue/grey eyes until I was 27 years old and then they shifted to green!

    Second, in college I learned about punnet squares. They are very helpful at determining the likelihood of what you’re children’s eye color will be. Brown eyes are dominant and pass on the dominant allele (B), while blue or green pass on the recessive allele (b). Everyone has two alleles and the combination of the two determine eye color (mostly–brown v blue or green). Any combo of alleles with the dominant allele will express the dominant trait, which is brown. So BB and Bb will express brown eyes (this includes brownish hazels) and bb will express blue or green eyes. It is impossible for two parents with blue eyes to have a brown eyed baby because they will only pass on the recessive allele.
    Example:
    – husband’s mom: brown eyes and all blood relatives have brown eyes; likely BB alleles
    – husband’s dad: blue eyes; bb
    – my husband’s eyes are brown with gold’s and greens (brownish hazel). There was 100% chance for my husband to end up with brown eyes See my attempt at a punnet square for him below:
    B. B
    b. Bb. Bb
    b. Bb. Bb

    – both of my parents have recessive eye colors so the both have the alleles bb which means me and my sisters were 100% going to have recessive eye colors.
    – now my husband (Bb) and my (bb) babies are 50% to have brown eyes and 50% to have recessive eye colors. See punnet square:
    B. b
    b. Bb. bb
    b. Bb. bb

    Hypothetically if two parents had Bb alleles they would have 75% chance for brown eyes and 25% chance for recessive
    B. b
    B. BB. Bb
    b. Bb. bb

    Typically BB is brown, Bb is brown hazel, and bb could be blue or green (I think there are more genes that go into it)

    So far our son has blue eyes, but I know they could still shift. Eye color is so fascinating and I hope everyone enjoys punnet squares as much as I do 🙂

    • My daughter went from blue to green at age 10… do you know why this happens later in where you experienced this too?
      Thanks

      • My first son had blue/gray eyes until he was about 5 years old, and then they changed to green. My mother’s eyes did the same thing. His Dad and eye both have hazel (brown & green) eyes. My son’s Dad said his eyes were also blue until around age 5, when his eyes changed from blue to hazel (brown/green). My 2nd son who is now only 11 days old, was born with dark blue eyes. From the side, I can see gold in the blue, so I am wondering if they will change to green, as well, or possibly hazel, and when this will happen, since his eye color now looks the same as my first son’s eyes looked this young. My first son’s did change to a lighter blue/gray color, & then green at 5 years old. My second son’s Dad has green eyes. Eyes are a fascinating mystery. I wish I knew why this happened, for eyes to change at 5 or 10 years of age, or even later in life, but I don’t. I don’t hear this happening much, though! Thanks for sharing..

  5. My baby has crystal grey blue eyes. With about 4 different shades of blue. Dad has blue eyes, I have green. However dad’s has sectoral heterochromia while I have the rings of heterochromia.

    It’s a big mystery what color eyes baby is gonna have because my mother has blue eyes and my dad has super dark brown. But i got my grandmother’s green eyes. Dad’s parents both have blue.

  6. My eyes are like my Dads. The were brown when I was young. But in adulthood, the have become more and more hazel the older I am. My moms are blue, and both sisters are blue. My husband are dark brown. His moms are black, his dads are blue. I have 8 kids. 7 with brown to dark brown, and a 3 month old that looks like maybe they might go blue. I hope!!!!

    • You need to put a cap on it. We get it, you like sex. But this world is so unbelievably overpopulated and your genes probably suck anyway, given how singleminded your are on sex and nothing else. You should see a therapist instead of procreating compulsively

      • Wow. It sounds like you need a therapist! Telling this women who loves life and creating it that she should stop because you don’t approve. You should put a cap on it. Mind your business. I wish I could afford to have that many kids. I cant even afford to have one yet. She must be doing something right if she can. If you think the world is overpopulated then you are contradicting your own existence or you think you’re more important than her kids. The world isn’t over populated. There is so much open land all around people just like to live in the city because there are more opportunities. There are so many jobs that need to be fulfilled. We just need to raise more hardworking people and set kids up for success.

  7. Eye color is all based on genetics and I do not see that mentioned at all in this post. I believe this needs to be included and mention that the eye color percentages are only a *general* guide, being that each persons genetical makeup is different. Brown eye color is dominant so if a child receives the gene for brown eyes from either mom or dad, they will have brown eyes regardless of the other gene (being recessive or dominant). The confusing part is that not everyone knows what two genes they received, particularly genes received from brown eyed parents (Having children can help to reveal this). A person’s eye color that is displayed only reveals one of the two genes. This post seems very anecdotal and I think the scientific part of this conversation needs to be mentioned, especially if people are interested in learning more on the subject.

    • My daughter has a very light green/blue/brown mix. They would be considered light blue if you were just looking at her from a normal distance.

      Her dad and I both have brown eyes. Mine are more of a darker hazel but her dads are a solid brown.

  8. I have dark brown eyes, my husband has bright blue eyes. All 4 of our children were born with black eyes. Now we have 1 hazel eyed child, 1 green eyed child, 1 blue and our 4 month old currently has blue eyes too. I was hoping for at least one of my children too look like me but I’m thinking I’m out of luck.

  11. I have brown eyes and my daughter’s father has dark brown eyes as well. However, my daughter was born with blue eyes that got lighter. She’s now 1year 7months and her eyes are blueish gray with the flecks of gold when looking from the side (as pointed out in the article).
    My mom has beautiful hazel eyes and I have great-uncles and cousins with blue eyes, so no idea if my daughter’s eyes will remain blue/gray or change color. Any ideas?

      • My eyes went from blue to hazel my first year. But as I got older, the color got lighter and more and more blue. By 4th grade you would look at them and say they were certainly green and not hazel. Then the green started turning more blue. Now in my 30’s, they’ve turned a light sea green/blue. However I still have the original gold ring around the pupil from when they were hazel. My brothers eyes are the exact same as mine except a little more blue.

    • My son was born with dark blue eyes, which turned into a really pretty light blue/gray color before he was 1. Then at around age 5, his eyes turned to a pretty green color. He is now 25, eyes still green. His dad and I both have hazel (brown/green) eyes. His Dad said his eyes were blue, too, until age 5 when they turned hazel (brown/green). And my Mom’s eyes were blue and changed to green, also, at age 5. My 2nd son is 11 days old, and has dark blue eyes, also. Wondering what color they will end up, & when. Fascinating.

  14. I was born with baby blues (mum has blue, dad has hazel) but during primary school my eyes would change colour each day (blue, to green to hazel) each day was a different eye colour until they stopped. I now have hazel eyes with more yellow than usual and a dark blue ring around the outside. My fiancé also has hazel eyes but his sometimes look light brown.

    We’ve just welcomed our daughter into the world and she had dark blue eyes at birth but now at almost 3 weeks she has bluey/green eyes but they look more towards green, which means she’s going to have a similar colour to my fiancé.

Then they got brown speckles in their eyes and by the time they were 2, they had brown eyes. My grandchildren had dark brown eyes as soon as they were born.

  21. My husband and I are both blue eyed and our firstborn has brown eyes… And since everyone’s ‘knows’ that blue+blue = blue, some snide comments have been made by some judgmental people…. But after further digging, I have discovered that scientists now believe that it is possible for blue +blue = brown because there is more than one gene that determines so eye color (so the traditional Punnet’s square we learned doesn’t quite work in this situation)… I was thrilled to learn this and to inform a particularly rude family member…. And I love my childs beautiful brown eyes.

  27. I have blue eyes and my husband has dark brown eyes and we have three children together. Our firstborn had dark gray eyes at birth and now has very brown eyes and brown hair. Our second child had red hair at birth and light gray eyes. Now eyes are light blue and hair is strawberry blonde. And our third had grayish blue eyes at birth and blonde hair but when he turned one his eye color seemed to still be changing. One day i’ll say yepp they’re blue but the next they’ll look tan and gray. I’ve also seen green. Not sure what’s up with those eyes!
