My grandmother's eyes changed from green to blue?!
Question: When she was younger she definitely remembers (as well as her friends and family) that she was born with green eyes and lived as a green-eye woman past her marriage. Today she has clear perfect sky blue eyes. The change was not instant, actually it was so gradual that no one noticed until her teenage granddaughter pointed out she had blue eyes (not knowing that once they were green).
How is this possible?

The actual color of the iris dos not change under normal ciscumstances. There is a group of medicines that are known to change the color of your irises but not in the way you decribe here.
What is more likely is that your grandma has developed something called Arcus Sinilus. It is a deposit of lipids at the limbus or area between the white of the eye, and the cornea. This is a normal aging change and is of no big significance. It used to be thought that people who developed this had high serum lipid levels, however, studies never proved this to be a true correlation. This does however, produce the change in the direction that you describe (darker to lighter).

dunno how it's possible... but i was born with brown eyes and now... well, see for yourself : http://patronus-light.deviantart.com/art...
well as you age your eyes get lighter and ligher, blue eyes are the result of the absence of color in a layer of the eye, the colored part, people born with blue eyes are missing color and so the part behind that color pigmented part shows and it is blue, her aging caused the pigment to go away and now you can see the underlying layer which is blue giving her blue eyes
no idea how it's possible, but a friend of mine had dark brown eyes when he was a little kid, but now, at 17, they're gray.
I'd guess it has something to do with pigments and stuff... like the way your hair goes gray or white as you age.
