Why does my eye change color?

Why does my eye change color? Changes in the pigmentation of the iris can be both intriguing and worrisome. By comprehending the factors that can lead to changes in eye pigmentation, one can ascertain whether the observed phenomenon is within the norm or necessitates consultation with an ophthalmologist. Remarkably, it is not solely the irises of infants that undergo a transformation in hue. Approximately few of individuals with irises of a lighter color exhibit the phenomenon of iridescence, wherein the coloration of their eyes undergoes a transformation in their later years. The irises of individuals with light brown eyes have the potential to undergo a lightening process, resulting in a hazel appearance. Conversely, individuals with hazel eyes may experience a darkening of their irises. Changes in the pigmentation of the iris leading to changes in eye color are infrequent occurrences.

Why do eyes change in eye color?

At times, changes in the size of one’s pupils may result in a perceived changes in your eye color. Fluctuations in eye color, wherein the hue may seem to vary between darker and lighter shades on different occasions, are frequently observed. The variability in color perception can frequently be attributed to factors such as lighting conditions, attire, and other contextual variables. The change of the final quantity of pigment in the eye is the sole requisite for a change in eye color. What are the possible causes or factors that could have led to this occurrence?

The chromatic attributes of one’s surroundings, encompassing the luminosity and attire, have the potential to create a perceptual shift in the appearance of one’s ocular hue. The irises of individuals with brown eyes have been observed to exhibit variations in hue in response to varying lighting environments. As an instance, they may exhibit a lighter hue when exposed to direct sunlight and a darker tone when situated in a shaded area. The reason for this phenomenon is attributed to the higher concentration of melanin in brown eyes compared to other eye colors.

The color of the eyes has the potential to undergo slight changes over time. It is a common phenomenon that the pigmentation of the iris in the majority of infants tends to intensify during the initial years of their life. During this period, the human body generates a comparatively darker biological pigment, commonly referred to as melanin. Changes in the size of the iris, whether it be dilation or constriction, may result in subtle changes in the pigmentation of the eye.

The change in the quantity of pigment-producing proteins synthesized is the most plausible rationale for a change in the color of the eyes

Numerous instances exist where changes in the environment result in variations in the production of protein. It is plausible for an individual’s eye color to undergo slight modifications during adulthood. Prolonged exposure to sunlight has been observed to result in a slight darkening of the color of the eyes. It has been observed that a minor proportion of individuals of Caucasian descent experience a lightening eye color as they progress in age. 

Regarding the phenomenon of adult eye color variation, it is plausible that environmental factors may influence one or multiple genes responsible for determining eye color. Consequently, numerous instances exist wherein environmental factors impact the level of gene expression. The impact of stress on genes that play a crucial role in the immune system has been well-documented.

In general, changes in your eye color are unlikely to occur. The manifestation of notable changes in the coloration of the eyes could potentially indicate the presence of an underlying issue. The present discourse aims to delve into the underlying causes that may lead to the manifestation of varying eye color and the potential factors that may trigger its change.

As per certain ophthalmologists-eye doctors, the change in eye color is not a spontaneous occurrence. The manifestation of one’s eye color on a particular day is influenced by a multitude of extrinsic factors in conjunction with one’s genetic makeup. Unless there are significant and abrupt changes in the pigmentation of your iris, there is no cause for concern.

The phenomenon of age-related changes in eye color that occur naturally

One of the frequently observed scenarios that results in changes in ocular pigmentation is observed in pediatric population. Infants typically exhibit lighter or bluer irises at birth. Primarily, this is due to the absence of sun exposure in newborns, leading to incomplete development of melanin in their eyes. The production of melanin increases upon exposure to light, leading to a change in the color of the eyes. Infants typically exhibit light blue or gray irises at birth, however, over time, the pigmentation of their eyes frequently deepens.

Eye color is determined by an individual’s genes and their body’s melanin levels. During the process of maturation, the concentration of melanin in the vicinity of the pupil tends to intensify, resulting in a darker appearance of the eye. It has been observed that a certain percentage of individuals with Caucasian ancestry experience a shift towards a lighter eye color as they progress in age. This phenomenon is attributed to changes or degradation in the pigmentation of the iris.

Nevertheless, changes in eye color may transpire as an individual progresses in age. Individuals with lighter-colored eyes, particularly those of Caucasian descent, may experience a gradual lightening of their eye color as time passes. The gradual degradation of the pigment over a period of time leads to a reduction in its chromatic intensity.

Is it possible for the color of your eyes to vary in response to changes in mood?

It is possible to observe variations in the hue of one’s eyes, with occasional differences in shades of blue eyes, green eyes, or brown eyes. Have you ever contemplated whether affective states may occasionally influence one’s perception in a given moment? It is not scientifically supported that an individual’s ocular pigmentation can undergo a complete change in eye color, such as transitioning from blue to green or brown to blue, in response to fluctuations in emotional state. 

The change in the size of one’s pupil is concomitant with the fluctuation of one’s emotional state, thereby resulting in a corresponding modification in the chromaticity of one’s iris. The human body releases oxytocin, a hormone, in response to various emotions such as happiness, sadness, anger, excitement, and fear, which results in the change of pupil size. Consequently, the dispersion or compression of pigments in the iris leads to a variation in the eye color.

1-Changes in the diameter of the pupil

The size of one’s pupils has the potential to induce a change in the coloration of the eyes. The phenomenon of changes in the size of the pupils leading to changes in the perceived color of the eyes has been observed. In the event that an individual’s pupils dilate, a reduced portion of their irises becomes visible, resulting in a comparatively darker appearance of the remaining irises.

Conversely, in instances where the size of one’s pupils is reduced, there is a likelihood of the eye color appearing brighter. This phenomenon can be attributed to the disparity between the dark eye color of the pupil and the adjacent iris.

2-The attire that an individual wears

Recalling one’s past experiences in art education, it can be noted that complementary colors have the ability to intensify each other. This phenomenon can be observed in various levels of schooling, ranging from elementary to college. The juxtaposition of red and green hues results in a perceptual phenomenon whereby the reds exhibit heightened vibrancy, while the greens manifest a greater sense of lushness.

This principle is also applicable to the determination of eye color. The chromophores present in one’s attire, such as shirts, jackets, ties, or scarves, have the potential to induce a transient change in the hue of one’s ocular irises. The perceived lightness or darkness of one’s eyes can be influenced by the color of clothing worn. Individuals with irises of lighter pigmentation may exhibit an optical phenomenon whereby their eye color appears to vary in response to the hues of clothing worn. The aforementioned phenomenon is a visual perception that arises due to the chromatic or illuminative environment in which the subject is situated.


According to popular belief, an individual’s dietary intake has a significant impact on their overall health, including ocular health. The pigmentation of one’s iris can be influenced by dietary intake. Frequently, the consumption of foods that are rich in iron can result in the enhancement of one’s eye color, whereas the ingestion of fish can amplify the intensity of the eye color.

4-Light condition

EnvironmentIt has been observed that individuals with lighter eye pigmentation frequently exhibit a bluish hue in their eyes when exposed to environments abundant in blue light, such as in a swimming pool or in proximity to a blue computer screen.

For examle, a blue color is essentially reflected by the eye. The manifestation of a blue hue in the eyes is a consequence of exposure to blue light, which can occur when an individual gazes at reflections of blue light, such as water, or when one fixates on blue light emissions from electronic devices, such as computer or television screens.


The principal manifestation of uveitis is photophobia and conjunctival hyperemia. However, the aforementioned medical condition has the potential to induce changes in the dimensions or configuration of your offspring’s pupil, thereby causing a discernible transformation in the appearance of their iris. If left untreated, uveitis has the potential to result in a loss of vision.

6-Ocular Trauma

Certain ocular traumas have the potential to alter the appearance of one’s eye color.

7-Pigment Dispersion Syndrome

The Pigment Dispersion Syndrome (PDS) is a medical condition characterized by the abnormal dispersion of pigment granules from the iris pigment epith The aforementioned ailment is characterized by the liberation of pigments from the iris, resulting in its atrophy and potential development of visual impairment and glaucomatous conditions.

8-Corneal problems

Corneal disease refers to a pathological condition affecting the cornea, which is the transparent front part of the cornea can develop scarring or discoloration due to various factors such as disease, infection, swelling, or injury. This can result in the formation of a hazy layer over the iris, which can cause a significant lightening of the eye color.


Change in eye color resulting from pharmacological treatment. Certain medications have been associated with the potential to induce a change in the pigmentation of the iris, resulting in a darker eye color. The chromatic changes induced by the medication may exhibit a permanent nature.

10- Heterochromia

Heterochromia is a condition characterized by the presence of eyes that exhibit either a difference in coloration or the presence of multiple colors.In the majority of instances, it does not give rise to any complications. Ocular anomalies often arise from genetic mutations or developmental irregularities during the maturation of the visual system. Occasionally, it may serve as an indication of an underlying medical ailment.

Is it possible to change the natural color of your eyes through non-invasive way?

Regrettably, the answer is negative if you mean food, mood, subliminal messages, drops etc But also yes for “Lumineyes” which is a non-invasive or non-surgical eye color change treatment. Similar to the hereditary nature of hair and skin pigmentation, the coloration of one’s iris is also determined by genetic factors. It can be inferred that a permanent change of my eye color necessitates a breakdown of their genetic code or cell structure, as it cannot be achieved without surgical intervention.
