I love this. I’m an optometrist and get to look at eyes up close every day, and I still love it.
For those who didn’t know already, the iris consist two muscles. And there is only one pigment in the iris, and that is brown, even if you have blue or green eyes
It's just that the structure of the molecules making up blue and green eyes refract light and only give if blue/green rather than brown? Or is it just a lack of melanin lol
