Does eye color change because of your mood?

Why do my eyes change color so offten. Its not based on my clothing either. I thin its because of my mood. Is that possible?





JennDoes eye color change because of your mood?
i don't know of anybody whose eye color changes... i guess it's the lighting. sometimes, blue eyes look like green. my brother says that at times the mirror has something to do with it. color pigmentation in your eye can never change, as far as i knowDoes eye color change because of your mood?
';color pigmentation in your eye can never change,';


not true, many babies are born with blue eyes and then as their eyes are subjected to sunlight, they change to their natural shade. Also some people's eye color changes with age.





I'm not so sure about changing with mood though. Report Abuse

Well I have green eyes and I've observed when I'm mad sad/upset or sunburnt, my eyes changes to blue. and when i was a little girl, I use to have light blue eyes, which have changed to a green. so i honestly beileve that your eye color can change. Report Abuse

Maybe Your Eyes Are Hazel Report Abuse

Actually, yes, they do. My eyes are normally yellow and green. When I'm angry, they turn black. Report Abuse

It's all a matter of color perception and the light. Here is a really neat website that ya'll may find amazing. http://www.echalk.co.uk/amusements/OpticalIllusions/colourPerception/colourPerception.html


Oh and btw I';m a ';gray'; eyed person myself whose eyes apparently shift from blue-gray-green Report Abuse

mine do, but they also change with lighting. i dont really think it's your ';mood'; but more scientific like when you are high your pupils dilate. I think when you are excited for example your eyes widen causing the light to hit them differently thus changing the color. i dunno its always been a mystery to me. I had one guy tell me that my eyes were drk green at night, blue when i was having sex and almost brown when i was angry. my eyes change from various shades of green, blue and brown

eye color


Eye color or eye colour is a polygenic trait and is determined by the amount and type of pigments present in the eye's iris[1][2]. Although there seem to be three genotypic eye colors (brown, green, and blue), humans and other animals have many phenotypic variations in eye color[3]. These variations in color are attributed to varying ratios of eumelanin and pheomelanin melanocytes in the iris.[2].

As the perception of color is dependent upon the conditions in which color is viewed, so is the perception of eye color.[4] The amount and type of illumination, as well as the color of the surrounding environment all affect color perception.








Brown Eye Variations





The brown eye of a biracial boy. Depending on the light, some dark eyes can range from medium brown to near black. The more the reflection, the darker the eye looks, giving them a glass-like appearance.The vast majority of the world's people have dark eyes, ranging from brown to nearly black. Light brown eyes are also present in many people, but to a lesser extent. Most of the original inhabitants of Africa, Asia, and the Americas have brown eyes. Brown eyes are also found in Europe, Oceania and North America, though within European populations they are not predominant to the same extent. Brown had been considered to be the most dominant eye color in any gene, but new studies have revealed that this is not always true[citation needed]. Very dark brown irises are, and may often seem black in color.








Black eyes


Black eyes are a very dark shade of brown. If a lot of melanin is present, the eye will appear very dark brown. Black eyes can also be caused by medical conditions, in particular aniridia, which is defined as the absence of an iris in the human eye. As the iris is the colored part of an eye, the person's eye will appear to be totally black, only a pupil. As the iris controls the amount of light that can enter the eye, this condition can have serious implications for a person's vision later in life.








Hazel Eye Variations





A hazel eye.Hazel is usually used to describe eyes that contain elements of both green eyes and brown eyes, in rare cases, also containing gray or blue, sometimes transitioning from green at the edges to brown around the pupil, and light brown. Hazel eyes often change color depending on what the person is wearing (i.e. if the person is wearing green or purple, the eyes appear mostly green). They are commonly found in middle European countries such as the middle of Russia, Belarus, Ukraine, south and middle of Poland, south and middle of Germany, north of France, Switzerland, north of Italy,Turkey, Slovenia and others.

















Amber eyes


Amber eyes are a shade of hazel and are often called light brown eyes. They have a yellowish/golden and russet/coppery tint and are not as common in humans. The golden tint appears at its brightest in direct lighting or sunlight, but turns into a golden green-brown in the shade or a coppery brown in candlelight. Amber eyes are also nick-named ';cat eyes.';








An amber eye.


Blue Eye Variations





Blue eyes are relatively common throughout Europe, especially in Northern Europe, including the northern Baltics and in East Central Europe.Among human phenotypes, blue eyes are a somewhat uncommon eye color. They are found mainly in people of northern European and eastern European descent, and to a lesser extent, in people of southern Europe[citation needed], the Middle East and Central Asia, most commonly in people who live at higher elevations. South Asians may also have blue eyes, but this is uncommon, except amongst Pathans and Parsis and people in Pakistan, and also in India. For example, blue eyes are most common in Punjab and Kashmir,with fewer numbers in Gujarat and Rajasthan. Finland and Lithuania have the highest percentages of blue-eyed people, with at least 80% in both countries respectively. Ireland and Great Britain also have high percentages of blue eyes, with estimates for being around 70% for Ireland and about 65% for Britain. Many Caucasian babies are born with blue eyes, though their eyes will darken, or change color. Most infants' eye color will set within a couple of days to a couple of weeks, though some people's will continue to change for a number of years.





Blue is the color of the indole monomer that when polymerised forms melanin[citation needed]. If both alleles for brown eyes (a polymerase gene) are absent or damaged, the blue color remains. Hence blue eye color is a recessive trait.





A 2002 study found the prevalence of blue eye color among non-Hispanic whites in the United States to be 57.4% for those born between 1899 and 1905 compared to 33.8% for those born between 1936 and 1951[5].








Gray eyes





Grey eyes.Gray eyes are a (often lighter) variant of blue eyes. A wide variety of shades of grey exist, from the almost white (light grey) to dark.








Steel Blue-Gray eyes.The underlying gray color may be tinted with various other colors, as in the greenish-gray eyes in the picture. ';Steel blue'; eyes are also found, ranging from a slightly desaturated blue to light blue-gray.





A yellow-, amber- or copper-colored ring is commonly seen around the pupil. This is a normal part of the iris, and should not be confused with Kayser-Fleischer rings. As with other colors, gray eyes are often seen to change color depending on the surrounding colors.








Blue-green eyes





Blue-green eyes: These are the same eyes, however depending on the light and surrounding hues, the eye color can appear quite different. Notice the copper ring around the pupil.Blue-green eyes are relatively uncommon and usually consist of an iris with a predominantly blue color, usually darker blue, with green streaks or stippling caused by a yellow- or copper-colored overlay. Yellow-, amber-, or copper-colored rings are often present around the pupil.





Blue-green eyes are considered a blue variant.[citation needed]








Violet eyes


Violet eyes are extremely rare and are a variation of blue eyes. They are believed to be caused by eyes having so little pigmentation that the red and blue blood vessels permeate through, causing a violet color of the iris. A noteworthy subject is Elizabeth Taylor, whose physical trademark is her violet eyes.








Green Eye Variations





Green eyes.Green eyes are rarer than brown, hazel, blue and gray eyes. Green eyes are most often found in people of Celtic, Germanic, and Slavic descent. Hungarians have the highest percentage of green eyes of any population, close to 20%.[citation needed] Green eyes are also found, though in far lower proportions, among other Caucasian populations in the Middle East and South Asia. They are so common among Pashtuns that in Pakistan, Pashtuns are often called ';Hare Ankheian Vaale';: those with green eyes (Hindi translation).[citation needed]. They may also be found in many areas of northern India, especially in Punjab and Kashmir.





One of the most famous photographs ever published by National Geographic was a close-up of Sharbat Gula, a Pashtun girl with startling green eyes, taken in western Afghanistan by Steve McCurry in 1984. Details of her irises captured by the photograph were used to confirm her identity after she was relocated in 2002.








Red Eyes


Red eyes are uncommonly found in persons who have albinism. This is primarily due to the lack of pigment which is characteristic of the condition. Because of this lack of pigment, the blood vessels underneath may lend a reddish color to the eye. Edgar Winter's eyes are an example of this trait.








Red-eye effect


Main article: Red-eye effect


The red-eye effect commonly appears in photographs taken with a flash, especially in those with light eyes. It is caused by light reflecting off of the retina, which is highly reflective, in much the same way light reflects off of the eyes of animals such as cats and alligators, making their eyes appear to glow. The effect is generally more pronounced in people with grey or blue eyes and in children. This is because pale irises have less melanin in them and so allow more light to pass through to the retina.








Heterochromia





An example of heterochromia iridis. The subject has a brown and green eye.Main article: Heterochromia


Heterochromia (also known as a heterochromia iridis or heterochromia iridium) is an ocular condition in which one iris is a different color from the other iris (complete heterochromia), or where the part of one iris is a different color from the remainder (partial heterochromia or sectoral heterochromia). It is a result of the relative excess or lack of pigment within an iris or part of an iris, which may be inherited or acquired by disease or injury[6]. This uncommon condition usually results due to uneven melanin content. A number of causes are responsible, including genetics and Waardenburg syndrome. Trauma and certain medications, such as latanoprost can also cause increased or decreased pigmentation in one eye. On occasion the condition of having two different colored eyes is caused by blood staining the iris after sustaining injury. David Bowie's eyes are a well known example of a trauma-induced Heterochromia.








Genetics


At one time scientists thought that a single gene pair, in a dominant/recessive inheritance pattern, controlled human eye color. The allele for brown eyes was considered dominant over the allele for blue eyes. The genetic basis for eye color is actually far more complex. At the present, three gene pairs controlling human eye color are known. Two of the gene pairs occur on chromosome pair 15 and one occurs on chromosome pair 19. The bey 2 gene(also called EYCL3), on chromosome 15, has a brown and a blue allele. A second gene, located on chromosome 19 (the gey or EYCL1 gene) has a blue and a green allele. A third gene, bey 1 or EYCL2, located on chromosome 15, is a central brown eye color gene.





Geneticists have designed a model using the bey 2 and gey gene pairs that explains the inheritance of blue, green and brown eyes.[citation needed] In this model the bey 2 gene has a brown and a blue allele. The brown allele is always dominant over the blue allele so even if a person is heterozygous (one brown and one blue allele) for the bey 2 gene on chromosome 15 the brown allele will be expressed. The gey gene also has two alleles, one green and one blue. The green allele is dominant to the blue allele on either chromosome but is recessive to the brown allele on chromosome 15. This means that there is a dominance order among the two gene pairs. If a person has a brown allele on chromosome 15 and all other alleles are blue or green the person will have brown eyes. If there is a green allele on chromosome 19 and the rest of the alleles are blue, eye color will be green. Blue eyes will occur only if all four alleles are for blue eyes.





This model can partially explain how two brown-eyed parents can give birth to a blue-eyed child. Also Caucasian babies are often born with blue eyes which turn brown as they get older. However this may not always occur because of genetic damage or environmental factors. If such a person has a child with another blue-eyed person then that child may inherit the gene for brown eyes.





This model explains the inheritance of blue, brown and green eyes but cannot account for gray, hazel or multiple shades of brown, blue, green and gray eyes. This suggests that there are other genes, yet to be discovered, that determine eye color or that modify the expression of the known eye color genes.





Eye color typically stabilizes by 6 years of age[7].
yes its possible.





ever heard of mood rings? if you find one, wear it. see it changes color every time your mood changes.
i think you may be seeing things. or in different lighting.
hmm...


i dunno exactly but it can
It happens to me all the time: dark brown eyes - you better get out of my way, hazelnut brown - everything's alright , green eyes - better get into bed quickly
i dont know..
I have been told mine get darker the angrier I get somethimes almost black.
now the eye color is change becuase it is that i don,t relationshipe long tmie
yes my dads changes color almost daily.





Mines get red when Im mad
no its not possible
Jenn,





I used to date a guy that one night he was over at my house and he had blue eyes before we started making out, and after about 10mins, I looked again and his eyes were green. during the relationship his eyes always changed colors depending upon his mood it seemed like.
