There are a number of things that can cause your eyes to change color. Many conditions, such as pigmentary glaucoma, horner's syndrome, Fuch's heterochromic iridocyclitis, neovascularization, trauma, pigment dispersion syndrome and anterior uveitis can all cause changes is the color of your iris.
The most common cause of changing eye color, however, is aging. This can be seen as a variation of normal in about 15% of all Caucasians. During aging a small number of eyes become darker in color however the vast majority become lighter due to the loss of pigmentation in the stroma of the iris tissue. This is because, unlike other areas of the body the iris doesn't make new pigment after birth so if the pigment is lost or looses density the color of the eye lightens.
Why does this happen in some people and not others? The answer to this question is not really understood although there is a strong genetic component to this process as shown by studying this process in identical twins.
