What Does It Mean When Your Eyes Change Color?

Question

My Boyfriend Has Eyes That Change From Green To Blue To Brown Quite Often... He Doesn't Have Hazel Eyes, But All We Know Is That His Eyes Turn Brown When He's VERY ANGRY. His Eyes Can Go From The Deepest Green To The Brightest Blue Without Any Cause At All... Today His Right Eye Was Blue And His Left Eye Was Green... Sometimes One Eye Will Be Half Green Half Blue, And Sometimes Gray... We Have Discovered That The Greener His Eyes Are The More Amerous He Feels! Please Let Us Know If You Have Any Explanation Or Comment... Thanks!

Answer 1

Multicolored eyes are fairly rare, usually benign, and frequently genetic in origin, occurring in maybe 1 percent of the population. Alexander the Great supposedly had them. So does rock legend David Bowie.  Some people's eye color does change for no apparent reason.  Others will sometime reflect the color of a shirt or blouse they are wearing.

Genes and eye color:

Stress, for example, is known to affect genes important for the immune system, which also may affect eye color. Certain foods may also affect eye color.  Read more about it at the source link.
