I’m not talking about the change as one get’s older. I’m talking about the seemingly random shift of dominant eye color as well as obvious iridescence. I know the iris is naturally iridescent, but it’s not always noticeable. Mine change all the time. The shift goes from brown, to green, to hazel, sometimes grayish bluish green, and sometimes there’s reds and yellows mixed in there along with whatever color decides to be dominant at the time. Other times my eye color is very non-human (feline, canine, etc). My usual, official color is brown. Anyone know of any type of spiritual significance to it? And if you’re not all that spiritual or interested in metaphysics, do you know of a biological explanation? I’m interested. Really. And it’s really cool to watch.
