Babies’ eyes are usually not their true color at birth. Most babies are born with either blue or grayish-blue eyes, and the color can change several times over the first several months of life as melanin production in the irises increases.
Generally, babies’ eyes will reach their true color by the time they are 6 to 9 months old, though this process could be quicker or slower depending on their genetic makeup.
In some cases, a baby’s eye color can even change after their first birthday. It is also worth noting that eye color is determined by the amount of pigment in the iris, and the thickness of the iris itself can cause certain colors to become more prominent or less prominent as time passes.
However, in most cases, once babies reach the age of 6-9 months, the color of their eyes will remain the same for the rest of their life.
When can you tell a baby’s real eye color?
It is typically not possible to determine a baby’s eye color until about 10 to 12 weeks after birth. While babies are born with some color in their eyes, this is often not the final eye color and can change as the baby grows and develops.
The eyes usually reach their permanent color sometime between 6 and 9 months old. Factors such as heredity, genetics and ethnicity will play a role in a baby’s final eye color. For instance, babies born to two blue-eyed parents are likely to have blue eyes themselves.
Due to the substantial factors that can play a role in determining a baby’s ultimate eye color, it is impossible to know for certain what a baby’s eyes will look like until sometime after their first birthday.
What color will GREY baby eyes turn?
The majority of babies are born with blue eyes, because the amount of melanin in their bodies is not yet high enough to fully determine their eye color. Over the following months and years, their eye color can change and become a range of different shades, including grey.
Many factors influence what shade a baby’s eyes will turn such as the amount of melanin in their eyes, the genetic makeup of their parents, and environmental factors. While some babies may remain with blue eyes for life, in most cases, their eyes will turn to a single or a combination of different shades including: brown, green, grey, blue-grey, and hazel.
When a baby’s eyes turn grey, this may be due to their eyes having a combination of a light blue color and a brown (golden) color due to the melanin in their eyes, with grey being the result. Oftentimes, grey eyes are the result of a combination of two different colors that have blended together, so a baby’s eyes may have blue, navy, brown, or yellow undertones in them.
As the baby matures, their eye color could continue to change and darken. In particular, they may darken more during puberty and adulthood as the amount of melanin in the eyes changes due to hormones and other environmental factors.
Can you tell if newborn will have colored eyes?
Unfortunately, it can be difficult to determine the eye color for a newborn baby. While eye color is typically determined by a few days after birth, it can take weeks or even months for a baby’s eye color to become permanent.
Differences in light, genetics, and the baby’s environment can all impact the color of their eyes. For most babies, permanent eye color is usually determined by six months to one year old. However, it is not always possible to accurately predict what color the eyes may eventually become, especially if the baby has multiple ethnic backgrounds.
In these cases, the eye color may shift or appear to change over time.
How do you know if baby’s eyes will stay blue?
It’s impossible to know for sure if a baby’s eyes will stay blue until they reach adulthood. Eye color is determined by a combination of genetics and environmental factors. When a baby is born, their eyes are usually blue due to a pigment called melanin not being produced yet.
As the baby grows, melanin production will increase and can cause the eye color to change. In some cases, it can take up to three years for a baby’s true eye color to show.
It can be helpful to look at the parents’ eye color when trying to determine the chances that a baby’s eyes will stay blue. Genetics play a large role in determining eye- color and if both parents have blue eyes, the chances are high that the baby will also have blue eyes.
Additionally, if one parent has blue eyes and the other has hazel or green eyes, the baby may be born with blue eyes but by adulthood the eye color could darken to a hazel or green.
It is important to note that the only way to know for sure if a baby’s eyes will stay blue is to wait until the baby is 3 years old or older and the eye color does not change.
Which parent determines eye color?
Eye color is determined by both genetic heritage from each parent and the combination of those genetic codes. A child’s eye color is genetically determined by the combination of the eye color genes inherited from each parent, including the dominance or recessiveness of each gene.
The genetic code inherited from each parent influences the amount of pigment – or melanin – in the iris. With more melanin, the darker the eye color. The variation in how much melanin is present and how it is distributed across the eye determines whether a person has brown, blue, green, or hazel eyes.
The majority of eye color is determined by the two following genes: OCA2 and HERC2.
The OCA2 gene is a brown/blue/green/hazel gene, typically found on chromosome 15. It is responsible for the production of melanin, and the intensity of its color can range from blue to brown. The HERC2 gene dictates whether the OCA2 gene will be expressed in the eye color.
The HERC2 gene is found on the same chromosome as OCA2 and both parents must pass it on in order for the OCA2 gene to determine the eye color. This gene can be recessive, meaning that even if a parent passes on the gene, if the HERC2 gene is dominant, the eye color will be dominant as well.
In summary, both parents have a role in determining the eye color of their child. A child’s eye color is determined on the genetic level with a combination of the eye color genes inherited from both parents, including the dominance or recessiveness of those genes.
The amount of melanin a person has, which is determined by the OCA2 and HERC2 genes, will ultimately decide a person’s eye color.
At what age do babies blue eyes turn brown?
The age at which a baby’s blue eyes turn brown can vary from baby to baby, with some babies’ eyes remaining blue well into the early childhood years. When melanin production begins, usually at around 6 months of age, the pigment that gives the eyes their color begins to appear.
Dark-eyed parents are more likely to pass on dark eye color to their baby, while light-eyed parents are more likely to pass on light eye color. The color of the baby’s eyes will continue to change over the first few years of life, culminating in their adult eye color, which is usually established between the ages of 3 and 5.
Some people will keep their blue eyes through adulthood, while others will notice their blue eyes darkening to shades of green, hazel, amber or brown.
Do all newborns have blue eyes?
No, not all newborns have blue eyes. Eye color at birth is usually determined by genetic factors, including the environment that the baby is exposed to. Some babies are born with lighter colored eyes, such as greens or yellows, or even darker eyes, such as hazel or brown.
Eye color may also darken over the first few weeks and months of a baby’s life due to the production of melanin in the iris. It is also possible for the eyes to remain their original color, blue or otherwise, if the baby does not produce much melanin in the iris.
Consequently, it is possible for a newborn baby to have any eye color, including blue.
How long do babies eyes stay grey?
The color of a baby’s eyes at birth is typically grey, which is a result of melanin – the same pigment that colors skin and hair – not fully developing yet. Most babies’ eyes will stay grey and start to show hints of color when they are between three and six months old.
By the time they reach their first birthday, their eye color should be fully formed and typically stays the same for the rest of their life. It is also important to note that even though both parents’ eye colors are a major contributing factor to the eye color of the baby, eye color can still unexpectedly change.
It is common to experience subtle shifts in eye color over time as well.
Why do grey eyes turn brown?
The phenomenon of a person’s eye color changing from grey to brown is extremely rare but it can happen due to a genetic mutation within the iris. Basically, the cells of the iris, which is the colored part of the eye, contain melanin which is what gives the eye its color.
If there is too little melanin in the eye, the eye will appear grey and if there is a normal amount of it in the eye, the eye will appear brown.
In some cases, a change from grey to brown could be due to a genetic mutation, wherein the production of melanin increases or is triggered with age, thus causing the eye to turn from a lighter color to a darker one.
This is known as ‘through-browning’ and in most cases, both eyes will change color. This is not to be confused with another phenomenon of eye color which is ‘pendulum eye color’, wherein only one eye will change color.
The cause of the mutation that increases melanin is unclear, and it is still not understood why it only affects some people, with some studies pointing to the possibility of hormones that signal a change in the structure of the melanin production.
In any case, If you experience a change in eye color, it is always advised to speak to an ophthalmologist who may be able to provide further insight.
How long does blue sclera last in babies?
The duration of blue sclera in babies depends on the underlying cause of the condition. Blue sclera appears in babies as a blue hue on the white of the eyes, due to a condition known as collagen deficiency.
This condition occurs when the body does not synthesize a collagen called scleral lamellae, which aids in the normal formation of the sclera. In some babies, this collagen deficiency is present at birth, while in others it may develop over time.
In cases of scleral lamellae deficiency, blue sclera typically resolves on its own as the body begins to produce the collagen by nine months of age. However, in other cases, when a baby is born with blue sclera due to a misalignment of the eyeballs or due to certain genetic conditions, the blue sclera may remain for life.
It is important to seek medical attention from an ophthalmologist if your baby has blue sclera in order to determine the underlying cause and find the best treatment plan.
Will my 5 month old’s eyes stay blue?
It’s impossible to tell with certainty whether or not your 5 month old’s eyes will stay blue. Eye color can change until around 1-2 years of age, so their eye color may change at some point. However, the chances of their eyes staying blue are high; babies with blue eyes tend to have a higher likelihood of keeping that eye color.
Additionally, the genetic component of eye color is complex with many factors that can influence the outcome. Therefore, it is possible that even if your 5 month old has blue eyes now, their eyes can change color due to other genetic factors that could be present.
Ultimately, you may not know the true outcome until they are a bit older. However, the chances of your 5 month old’s eyes staying blue are high.
How long does it take for babies to lose their blue eyes?
Most babies are born with blue eyes, but the iris color usually starts to change around 3 to 6 months of age. The color change is influenced by genetic factors, with some babies developing darker eyes faster than others.
However, it can take up to a year or more for a baby’s eye color to become more permanent. In some cases, eye color will continue to darken and change for several years. Even though the majority of babies’ blue eyes turn to a different shade within the first year, it’s also possible for babies to keep their blue eyes into adulthood.
Can blue eyes turn brown after 6 months?
It is generally not possible for someone’s blue eyes to turn brown after six months. Eye color is determined by genetics and is determined at birth, meaning eye color will not change over time. It is possible to see changes in eye color if a person wears contact lenses or temporarily dyes their eyes, but those changes will be reversed when the lenses or dye are removed.
If a person’s eyes seem to be changing color over time, they should speak to an eye doctor, as this could be an indication of a change in eye health.
Can blue sclera be normal in babies?
Yes, blue sclera can be normal in babies. The sclera is the white part of the eye, and it is often blue when a baby is born. This is because the blood vessels that supply the sclera are very close to the skin.
The blue color will usually fade as the baby grows and the blood vessels move away from the skin. In some cases, however, the blue sclera may persist into adulthood. This is a harmless condition known as sclerocorneal or “blue eye” syndrome.
It is caused by a defect in the connective tissue of the sclera and it does not affect vision. Some people with this condition may develop hazy vision later in life due to corneal degeneration.
