The Greening

As I get older, I find my eyes becoming more hazel, and some days they are very green. I was on the couch and snapped this picture. The green in my eyes really stood out. I think the camera picked up some of the blue in the pillow which made them seem so green, but I thought it was interesting. No, I did not muck with the picture. All the other colors are true (sweatshirt, pillows, couch, hair). The flash did wash me out though. I wonder if this will continue as I get older? Is it normal for eyes to change color with age?
