Is it possible to lose pigmentation in your eyes?

Question

Is it?

i know brown eyes have the most pigmentation and green eyes have the least?

Answer 1

There are a few disorders that can lead to pigment loss in eyes and a few things that can make it appear the eyes are changing colors.  Pigmentary dispersion syndrome is a result of some of the pigment flaking off and can clog the drainage structure and possibly lead to glaucoma.  But, it won't usually cause your eyes to appear a different color.  Arcus, which is a white ring that forms around the cornea due to age or high cholesterol, can make eyes appear to be changing into a blueish color.
