OK, none of the above describes my eyes. For the first 40 some years of my life both of my eyes were brown. Then, gradually, some green became apparent in both eyes, surrounding the pupils. The green has increased to the point where my inner half of my irises are green, and the outer half are still brown. The effect has taken about a decade.
P.S. I am not constipated, and I have perfect pitch. I am not aware of any disease or injury to my eyes.
Why did my eye colors change, in both eyes? I've asked opthalmologists and my family doctor. They both look at me like I'm crazy.
My wife loves my 'new' eyes, but I'm baffled, and a bit concerned, as to why the color changed after forty-some years.
