I would recommend looking into iridology for sure! This is a fascinating area for me, as well, and I would like to hear more about your diet and supplements. I have "brown" eyes which are actually turning blue, but very slowly. They are more hazel/green now than blue, but are heading in that direction.
I am not surprised to hear that your eyes are lightening and clearing up now that some significant stress has been solved.
Being hungry is good--most women do not eat enough in general, let alone enough wholesome, nutritious food. What foods are you eating more of now?
