Why Are My Eyes Sometimes Green And Sometimes Blue?
Increased Sun Exposure – As previously mentioned, exposure to light causes your body to produce more melanin. Even if your eye color has set, your eye color could slightly change if you expose your eyes to more sunlight. As a result, your eyes might appear a darker shade of brown, blue, green, or gray, depending on your current eye color.
Why do my eyes look green sometimes?
Green Eyes Trivia – 10 Fun Facts About Green Eyes –

Green eyes don’t actually have any color. That’s right – strange but true! While green eyes appear that lovely shade of emerald to the outside observer, the irises themselves have no actual pigment. Similar to blue eyes, the color we perceive is a result of the lack of melanin in the iris.
In fact, in Ireland and Scotland, more than three-fourths of the population has blue or green eyes – 86 percent! 
Many factors go into having green eyes. Sixteen separate genes have been identified as contributing to eye color. So, no matter what eye color your parents have, yours could end up being just about any color. Green eyes naturally occur in all races of people. 
Liqian, China is a hot spot for green eyes. There is a village in China called Liqian, in which two-thirds of all inhabitants today have green eyes and blonde hair.

Why are my eyes green one day and blue another?
Development of Heterochromia – If you’ve developed a rare condition called heterochromia, your eyes likely have changed color significantly. Heterochromia refers to a condition where each iris has a different color. However, a few kinds of this condition exist.
Partial heterochromia means parts of your irises are different colors. One corner might look green while the rest of the iris looks blue. Central heterochromia refers to a condition where your iris has two different colored rings. You might be born with this condition, and if you are, it doesn’t affect your health.
However, you can acquire heterochromia as an adult from:
Eye surgery Eye bleeding Eye swelling Eye injury Developing of glaucoma Developing of tumors in the iris
Some of these causes can have adverse effects on your ocular and overall health. If you’ve noticed a drastic change in your eye color as an adult, you may need to see an ophthalmologist or optometrist to rule out any possible health risks.
Why are my eyes half blue half green?
Can people have different colored eyes? – A condition called heterochromia causes the iris to be different colors. People with this condition may have different colors within one eye (for example, the iris may be half one color and half another). Or they may have a different color in each eye.
Why do green eyes change color with mood?

Human eye color has always been fascinating and mysterious. Babies are usually born with blue eyes. Those mostly change within the first three years to other colors. Some people have different colored eyes; they were celebrated back in July with “Different Colored Eyes Day.” Some emotions can cause the eyes color to change, such as when you’re angry.
Scientists still don’t know why some people’s eyes are a certain color. It is known that human eye colors originate with three genes, obviously passed down from your parents. Thing is, only two of those three genes are understood. Those two give people the common eye colors of green, blue, and brown. But scientists don’t understand why other people have gray, hazel, or eyes with multiple colors in them.
Back in the 60s the common thinking was that brown eyes were “dominant” gene traits and blue eyes were “recessive,” but that’s too simplistic. Eye colors don’t turn out to be a blend of your parents’ eyes. Really, the only predictor is if the parents both have brown eyes, then the baby will likely also have brown eyes.
- Dark colors dominate more, so brown wins out over green, which wins out over blue.
- Baby eyes are interesting in themselves.
- Most babies are born with blue eyes and everyone watches to see if those eyes are going to another color.
- This darkening is due to melanin, just like in the skin.
- Babies don’t have melanin in their eyes at birth, but it develops with age and can make the eye color darken.
Some children are born with irises that don’t match in color. This can be caused by trauma in the womb or shortly after birth, a benign genetic disorder, or a developmental issue in the transport of pigment. Although, an eye doctor should check this, there is usually nothing serious about the condition.
- Hence, you get Kate Bosworth with her one hazel eye and one blue eye.
- Change your mood, change your color The iris is the part of the eye that carries the color.
- It is a muscle that expands and contracts to control the size of the pupil.
- The pupil gets bigger in low light and smaller in bright light.
- It also changes shape based on what you are doing, shrinking when you are doing close up things such as reading.
The cool thing is that when the pupil changes size, the pigments in the iris compress or spread apart. This changes the eye color to a degree. The pupil can change size with certain emotions, thus changing the iris color dispersion and the eye color. You’ve probably heard people say your eyes change color when you’re angry, and that probably is true.
- Your eyes can also change color with age.
- They usually darken somewhat.
- This happens more to white people (10 to 15%) because they tend to have lighter eye colors to begin with.
- If you have dramatic changes in eye color, or if one eye changes, you need to see an eye doctor.
- Such changes can be warning signs of certain diseases such as pigmentary glaucoma,
And what would you think is the most attractive eye color? In a website poll of over 66,000 respondents, 20% said green was the most attractive, followed by hazel and light blue at 16%. Brown was far and away voted the least attractive (6%). But don’t take it personally, brown-eyed people; you can always opt for colored contact lenses, just like they do in the movies.
Why are my eyes sometimes green and sometimes hazel?
Are My Eyes Green or Hazel? – The effect of Rayleigh scattering coupled with a higher melanin concentration around the pupils gives hazel eyes their characteristic brown-to-green color. All hazel eyes basically have some combination of two distinct colors when viewed under normal lighting—brown/gold and green coloring.
- The magnitude of the brown color varies from person to person and is directly proportional to the amount of melanin in the iris.
- Hazel eyes may have a yellowish-brown, dark brown, or amber-brown surrounding the pupil.
- Some folks with hazel eyes observe shifts in their eye color between hazel and green or brown.
This is usually caused by a change in environmental factors such as the amount of lighting in a room and the color of surrounding objects. This shift in eye color also depends on the ratio of brown-to-green in the iris. When green is more pronounced than brown, hazel eyes tend to be perceived as green in green lighting or in the presence of a bright green object in the surrounding—like a bright green party gown.
- On the other hand, when brown is more pronounced than green then hazel eyes may appear brown in the presence of a brown object in the surrounding.
- This is why we tend to easily mistake hazel eyes for green or brown eyes.
- As we have seen above, there is no physical change in the eye accompanying this color shift.
What actually changes is the way we perceived the eye color.
