How To Tell If Your Babies Eyes Will Stay Blue?
- Pieter Maas
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. ()
- 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.
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. Get free updates on baby’s first year! – Free Updates on First Year
Will my 6 week olds eyes stay blue?
Are All Babies Born with Blue Eyes? – You’ve probably heard that all babies are born with blue eyes—but experts say it’s a myth. “Babies are born with all different colored eyes. Some have dark eyes already and some have blue,” says Mohamad S. Jaafar, MD, a pediatric ophthalmologist and chief of the division of ophthalmology at Children’s National Health System in Washington, DC.
It’s not a hard-and-fast rule, but Caucasian babies tend to be born with lighter eyes, while those of African-American, Asian and Hispanic descent are usually born with brown or dark brown eyes, even eyes that look black. 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. Louis Children’s Hospital. As a general rule of thumb, baby eye color tends to get darker if it changes.
What determines a baby’s blue eyes?
Making Eye Color Predictions with Basic Genetics – If you want to try and predict your baby’s eye color, pull out your high school biology textbook to help narrow down just how likely it is that your baby will have blue eyes. If you didn’t keep it, don’t worry, I’ll give you a quick review.
As FamilyEducation’s Genetics Expert, I have developed my knowledge on these topics through a combination of college classes, teaching, and self-study. We all inherit two copies of each gene (allele), eye color included. One copy comes from our mother, and one from our father. Both alleles are stored in our chromosomes (our genetic code) and can be passed on to our children, but only one presents in how we look.
Dominant genes present while recessive genes “hide out” in the DNA code for a chance to pass on to future generations. Generally, darker colors are the dominant traits, while lighter colors are recessive, so a person with one brown-eyed gene and one blue-eyed gene will have brown eyes.
Blue eyes + blue eyes = 100% chance of blue eyes Brown eyes + blue eyes = 50% chance of blue eyes, but only if the brown-eyed parent carries a blue-eyed gene. If not, the chance is 0% Brown eyes + brown eyes = 25%, but only if both parents carry the blue-eyed gene. If not, the chance is 0%
It is important to remember that this theory is a simplified version of what really happens at the genetic level. Human eye coloring is actually controlled by a complex genetic process and there are many different eye colors other than just blue eyes and brown eyes.
How long does it take for a baby true eye color to show?
Eye color changes over time – Iris color, just like hair and skin color, depends on a protein called melanin. We have specialized cells in our bodies called melanocytes whose job it is to go around secreting melanin. Over time, if melanocytes only secrete a little melanin, your baby will have blue eyes.
If they secrete a bit more, his eyes will look green or hazel, When melanocytes get really busy, eyes look brown (the most common eye color), and in some cases they may appear very dark indeed. Because it takes about a year for melanocytes to finish their work it can be a dicey business calling eye color before the baby’s first birthday.
The color change does slow down some after the first 6 months of life, but there can be plenty of change left at that point. Eye color is a genetic property, but it’s not quite as cut-and-dried as you might have learned in biology class.
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. If one parent has brown eyes and the other has blue eyes, odds are about even on eye color. If your child has one brown eye and one blue eye, bring it to your doctor’s attention; he probably has a rare genetic condition called Waardenburg syndrome.
Do grey eyes turn green?
Posted by Eye Doctors of Washington in General Eye Care When someone wants to enhance their vision, they may try contact lenses or seek out LASIK eye surgery, But what if they want to change the color of their eyes? People have long been fascinated with eye color; after all, eyes come in a wide range of shades. The colored part of the eye is called the iris. The iris has pigmentation that determines the eye color. Irises are classified as being one of six colors: amber, blue, brown, gray, green, hazel, or red. Often confused with hazel eyes, amber eyes tend to be a solid golden or copper color without flecks of blue or green typical of hazel eyes. Blue eyes have a low level of pigment present in the iris. Recently, scientists announced that everyone with blue eyes is related! Because of various racial groups intermarrying, blue eyes, which are generally recessive, are becoming rarer and rarer. (Note: I recently asked my blue-eyed in-laws how they produced my amber-eyed spouse, incorrectly telling them it was genetically impossible. Brown is the most common eye color. Individuals with brown eyes have more melanin present, and over half of the people in the world have brown eyes. Gray eyes may be called “blue” at first glance, but they tend to have flecks of gold and brown. And they may appear to “change color” from gray to blue to green depending on clothing, lighting, and mood (which may change the size of the pupil, compressing the colors of the iris). Green is the least common eye color, but it is found most frequently in northern and central Europe. I have always incorrectly called this color eye hazel! Hazel eyes mostly consist of shades of brown and green. Much like gray eyes, hazel eyes may appear to “change color” from green to light brown to gold. Individuals whose eyes appear to be one color closest to the pupil, another color a little farther our, and another color around the edge of the iris are likely to have hazel eyes. Red eyes do exist. “Red?” you say. “Yes, red,” I say, although we often call them pink. Picture white bunnies with pink eyes. What you’re actually seeing in these rabbits and in albinos is the blood vessels behind the iris. Because there is so little melanin in the eyes, there is nothing to conceal the blood vessels hard at work. If you’re dissatisfied with your eye color for whatever reason, there are always colored contacts. Just be sure to get a prescription for them from your eye doctor at Eye Doctors of Washington, Don’t buy them online or borrow them from a friend—you’d just be begging for an eye infection.

THE CLAIM – Eye color can change as we age. THE FACTS – It can bend light, bring the world into focus, and next to the human brain may be our most complicated organ. But for many people the most intriguing feature of the human eye is simply its color. Can it really change for no apparent reason? In most people, the answer is no.
- 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.
- Eyes that have a lot of it in the connective tissue at the front of the iris, called the stroma, are darker, while those that have less tend to be lighter.
The levels of melanin generally remain the same throughout life, but a few things can change them permanently. The first is a handful of ocular diseases like pigmentary glaucoma. Another is a condition called heterochromia, or multicolored eyes, which affects about 1 percent of the population and is often caused by traumatic injuries.
An example of this can be seen in the rock star David Bowie, who attributes his contrasting eye colors, hazel and light blue, to a blow to the face as a child. The third cause appears to be genetics. A study in 1997, for example, looked at thousands of twins and found that 10 percent to 15 percent of the subjects had gradual changes in eye color throughout adolescence and adulthood, which occurred at nearly identical rates in identical twins.
THE BOTTOM LINE – Eyes can change color in some people because of genetics or injury. ANAHAD O’CONNOR Really? [email protected] : The Claim: Eye Color Can Change as We Age (Published 2005)
