Shift.ms is better if you're logged in

I was wondering if anyone else have noticed their iris color changing as their eyes constriction and dialate with light? I have gotten it on video twice now, my eyes changing from dark green almost brown to a light sage or even grey and almost blue or white. I know I am a glaucoma "suspect" and had to have surgery on my eyes and do have a cyst on my eye, but was wondering if anyone else experiences this or has heard of this being an MS symptom? I have Hazel eyes, so it isn't uncommon for my eyes to appear different colors at times, but, I.never noticed my eye color changing do to light exposure before.
