What causes eyes to change color?!


Question: Eye color change
Often, paler newborns have blue eyes, which change to green, hazel, light brown or dark brown, as they grow older. This is probably the origin of the idiom "being blue-eyed" (i.e. na?ve; gullible).

It is thought that exposure to light after birth triggers the production of melanin in the iris of the eye. By three years of age, the eyes produce and store enough melanin to indicate their natural shade. While changes in eye color of infants are more common, even in adults, eye color changes are seen, most often as a result of exposure to the sun. Sunlight triggers melanin production in the eye, as it does to the skin.

Eyedrops containing a prostaglandin analogue (such as latanoprost) may result in a permanently darkened iris; these eyedrops are commonly used to treat open-angle glaucoma.

depends on the light and ur enviornment ur eyes absorb light

Eye color doesn't usually change except during the first few months after birth except with contacts or chemicals.

Anything from your mood, to the amount of sunlight you are exposed to, to your age.

there are some contributors to that, although one very common way is when people use colored contacts. If they happen to use them enough the contact can permenently die your retna to that specific color.

its just due to refracted light that travels in your retina, thus enabling it to emit different colors, thus constriction and dilation of the pupil thus it part.
