I looked all over for answers to this question. I have a slightly different issue to add to the mix.
I want to understand why my eyes change colors and some of the explanations on here are reasonable, however, they do not pertain to my situation.
I have three daughters. We all have 'starburst' eyes. All of our eyes change between blue, green, gray, gold, and a 'starburst' of all 4. On a
normal basis, they are all 4 colors in ring like patterns that resemble a starburst to me.
My daughters eyes change when my change. This has been observed by different people.
I can sit in a room, with the same lighting, in the same clothing, no makeup. If I get upset my eyes will change to deep blue. In another room, in
different lighting, my daughters eyes will change as well.
When I cry they are bright green. My daughters eyes will all change to bright green.
So, as you can see, I can understand the scientific explanations on one level....but not on another.
If anyone can explain that one, I am all ears
