    In babies, the change in eye color is a result of the development of pigmentation. For adults the change in eye color could be a warning sign of some serious medical conditions. As many as 15% of Caucasian adults have some change in their eye color as they age, typically from darker to lighter, but if an adult's eyes change color dramatically, suddenly or the change is noted in only one eye, he or she should seek immediate medical attention. It could be the result of conditions such as fuch's heterochromic iridocyclitis, horner's syndrome and pigmentary glaucoma. Throughout our lifetime, the human eye may appear to change colors, even if the effect is only slight, because of lighting, mood and to some extent, what we are wearing. The iris, which is the colored part of the eye, is a muscle which in part controls the size and shape of the pupil. The pupil is wider in times of low light and is narrower in times of bright light. When the iris expands or contracts around the pupil, the pigments of its surface are either spread out or compressed together affecting the color that we perceive. In addition, certain emotions may cause the pupils to dilate and thus change the color of our eyes. What we wear doesn't actually cause a physical change in the color of our eyes; however the perception of our eye color can be affected by the clothing, makeup or jewelry that we are wearing.

    Some people say the color of their eyes has changed with age or can change with their moods. Actually, eye color doesn't really change. Most Caucasians are born with light eyes, but the pigment tends to settle by about a year.Some studies suggest that eye color can change a tad with age, but for most people, eye color is fixed after the first year of life.There are exceptions, such as during puberty or pregnancy, when pigments might darken slightly. Bloodshot eyes or what color shirt you're wearing may make your eyes appear to change color.

    changing colors of the iris is due to gene alteration of the cells there in your iris. on other words, it's because of your DNA. No answer has been found why do these cells alter their genetic make-up. Iris also contains melanin. If the body is exposed to UV rays.melanin production increases.Your skin becomes dark, but other melanin containing parts of the body, takes time before they can produce melanin to protect the body from UV. Whites have less melanin,Look at the hair and the skin.So light pigment is seen.and so are the eyes. But look at the brown and black people.they have more melanin.Look at the hair and skin, more pigment is seen and so are the eyes.It's really uncommon to see a black man with blue or green eyes.and a blonde with black eyes...
