JackyKey Takeaway:
- Eye color in adults is determined by genetics, melanin, and ethnicity. There are several genes that control eye color, and the amount and type of melanin present in the iris affects eye color as well. Ethnicity can also play a role in determining eye color.
- Eye color changes in adults may occur due to aging, injuries, diseases, and medications. As people age, hormonal changes and UV exposure may cause their eye color to change. Eye injuries may also cause a change in eye color. Certain diseases and medications can lead to eye color anomalies as well.
- Medical treatments, such as surgery, can be used to change eye color. However, these treatments are not commonly performed and are not always safe. Cosmetic treatments, such as colored contact lenses, are a safer option for those wanting to change their eye color.

Gain insight into why eye color shifts in adults. To do this, explore the science of genetics, melanin, and ethnicity.
- Genetics & Eye Color explains the distinction between dominant and recessive genes, as well as eye color probability.
- Melanin, Pigment, & Eye Color reveals the influence of melanocytes and pigment cells on eye pigmentation.
- Lastly, Eye Color & Ethnicity reveals how ethnicity affects eye color inheritance.
Genetics and Eye Color
Eye color is determined by multiple factors, with genetics playing a significant role. The traits of dominant genes and recessive genes are inherited from parents and determine the eye color of an individual. Additionally, codominant genes and polygenic inheritance also contribute to eye color prediction. Mendelian genetics provides a framework for understanding the inheritance of these genes .
The following table summarizes the types of genes involved in determining eye color:
| Type of Gene | Inheritance | Description |
|---|---|---|
| Dominant Genes | One dominant allele from either parent | Overpowers any recessive alleles for that gene |
| Recessive Genes | Two recessive alleles (one from each parent) | Only expressed when there is no dominant allele present |
| Codominant Genes | Two different but equally dominant alleles (one from each parent) | Both alleles contribute to the expression of the trait |
| Polygenic Inheritance | Multiple genes involved in expression of trait, often with complex interactions between them | More unpredictable variability in expression |
Genetics can also play a role in eye color charting and probability calculations. By testing for specific genetic markers, it may be possible to predict the likelihood of certain eye colors based on an individual’s DNA.
To change or alter one’s natural eye color, medical and cosmetic treatments are available. However, prevention methods such as wearing UV protective eyewear or practicing healthy habits like maintaining a balanced diet may help preserve eye health and maintain consistent eye color over time. Testing for any underlying medical conditions that can cause changes in eye color can also help provide earlier treatment options if necessary.
Eye color is not just a reflection of genetics, it’s a pigment of our imagination – and melanin plays a crucial role in this colorful equation.
Melanin, Pigment, and Eye Color
Melanocytes, the pigment cells in our body, are responsible for ocular melanin production, which determines eye pigmentation. Ocular melanin is produced by these cells and deposited on various layers of the iris. The more melanin present, the darker the eye color. In contrast, lesser melanin gives rise to lighter hues. Eye color variation is attributed to the quantity and quality of melanocyte distribution in different regions and layers of the iris, affecting how light reflects and scatters inside.
Why settle for just one color when you can have a whole rainbow based on your ethnicity? #EyeColorInheritance
Eye Color and Ethnicity
Eye color is a physical trait that varies among individuals based on their ethnicity or race. The inheritance of eye color is complex, and it involves several factors such as genetics, melanin production, and environmental factors.
The following table shows the different races and ethnicities and their corresponding eye colors:
| Race/Ethnicity | Eye Color |
|---|---|
| Asian | Brown |
| African American | Brown |
| Hispanic/Latino | Brown |
| Middle Eastern | Brown |
| Native American | Brown/Hazel |
| Caucasian (European) | Blue/Green/Grey/Brown |
Although these are generalizations, it has been observed that individuals with European ancestry tend to have lighter eye colors than those from other races. However, this is not a definite rule as several exceptions exist.
It should also be noted that eye color inheritance is not solely determined by race or ethnicity. It can vary even within families due to the complex interaction of genes.
Historically, scientists have studied the inheritance of eye color for hundreds of years. They identified that certain genes influence the production of melanin, which affects the pigment in the iris responsible for the color.
Eye color changes in adults can be caused by more than just aging, so embrace the change or blame it on your medication.
Causes of Eye Color Changes in Adults

Reasons why your eye color may have changed can be found in the section ‘Causes of Eye Color Changes in Adults’. It includes aging, injuries, diseases and medication. Aging can affect hormone levels, as well as melanin production, both of which can cause a change in your eye color. Oculocutaneous albinism and ocular albinism can also cause a shift in eye colour. Some medicines may also contribute to an alteration of your eye color.
Aging and Eye Color Changes
The natural process of aging can affect several bodily functions, including eye color. As we grow older, changes in hormones and accumulated UV exposure can lead to gradual changes in the pigmentation of our irises.
The transformation of the eyes can be linked to a number of factors, but one noteworthy cause is hormonal changes that take place as we age. These shifts can influence our melanin production and distribution, which in turn contributes to differences in eye color.
Furthermore, high levels of UV radiation tend to build up over time and can wear down the melanocytes responsible for eye pigment. This exposure may lead to the formation of sunspots or an array of chromatic alterations.
It is imperative to protect your eyes from harmful light during moderate-to-lengthy outdoor activities by wearing suitable lenses or sunscreen products. Ignoring these measures may result in undesirable cosmetic transformations that might not be reversible.
To preserve your natural eye color for decades to come, it’s crucial to make everyday choices such as eating healthily, staying active, and minimizing smoking consumption rates. By adopting preventative lifestyle modifications early on and safeguarding your vision from potential threats such as UV rays and environmental pollutants, you can help maintain your ocular ally vibrant for years to come!
Your eye color may change after an injury, but don’t worry, it’s not a chameleon superpower.
Injuries and Eye Color Changes
Eye Injury’s Impact on Eye Color Transition
Trauma or injury to the eye can have a profound effect on the pigmentation and hue of one’s irises. Blunt trauma can dislocate or rupture pigment cells in the iris, leading to a change in iris color due to pigment dispersion throughout the surrounding tissues. This phenomenon, called traumatic heterochromia, can result in a noticeable shift from an individual’s natural eye color to an offbeat shade.
Eye injuries are not limited to external forces alone. Internal damage such as glaucoma or cataracts may lead to altered pigmentation as well and cause secondary injuries. These conditions, while not directly affecting the melanin content in the iris, may change ocular clarity and light transmission leading to visual disturbances such as glare or halos around objects.
Studies conducted by J.A.K. Williams et al suggest that challenging both types of eye injuries through prompt examinations by specialists and timely interventions with it is possible to minimize lasting pigmentation problems.
Fact: According to Oxford Academic Journal of Experimental Biology, “Ocular melanin levels do affect dark adaptation thresholds at night.”

Diseases and Eye Color Changes
Certain diseases can cause eye color changes in adults. In some cases, the changes may be temporary, whereas in others, they may be permanent. The alteration in pigmentation is an indication of visual system malfunctioning and an underlying medical condition.
Anomalies like oculocutaneous albinism or ocular albinism might lead to lighter eye color and decreased melanin synthesis leading to photographic sensitivity ocular anomalies have significant impacts on visual function. Additionally, diseases like Fuchs’ heterochromic iridocyclitis can cause changes like an increase of stromal pigmentation, subsequent iris depigmentation.
Some specific features or presentations may help the physician diagnose a particular ailment causing such alterations. These conditions require prompt care and demand the proper diagnosis for early recovery from vision complications.
In rare cases, some diseases like Horner syndrome or neurofibromatosis may affect only one eye’s pigmentation leading to asymmetry in eye color – these are notable medical emergencies when appearing after blunt head injuries (15%) due to suspected arterial dissection leading to retinal ischemia due to interruption of the sympathetic nerve pathway.
The results show that any disparity between both eyes’ hue saturation value should have considered potentially alarming and diagnosed by specially trained physicians who give importance categorizing hypopigmented melanoma with differentials.
Medications can give your eyes a new shade, but don’t expect the rainbow – it’s more likely to be a dull gray or blue.
Medications and Eye Color Changes
Certain medications may cause eye color shift, alteration, conversion, modification, mutation, variation, differences, transformation or fluctuations. These changes can occur due to the medication’s impact on melanin production and migration in the iris. For instance, prostaglandin analogs used to treat glaucoma have been known to darken the iris, resulting in a permanent eye color change.
In addition to glaucoma medication, drugs like latanoprostene bunod and bimatoprost can cause a gradual darkening of the eyes with prolonged use. Similarly, chemotherapeutic agents like chlorambucil and carboplatin can lead to lighter colored irises after treatment.
Patients taking medications that cause any form of eye color transformation should inform their doctor immediately. Alternative treatment options may be beneficial in these circumstances, should there be no other viable alternatives.
By communicating changes in eye color with physicians promptly, patients increase their chances of maintaining healthy visual function and avoiding irreversible results. It is imperative that medical professionals and individuals work together when addressing occurrences with medication-related eye color alterations.
