Does anyone know why eye color sometimes changes day to day, or even hour to hour? My eyes are an icy blue when I'm depressed, and a warm gray blue when I'm happy. My husband's eyes are usually hazel, but when he's really happy they're solid brown and when he's sad they're green.
Does anyone know why this happens? I'm really curious- and no it's not the lighting, it holds true indoors, outdoors, and nighttime. Is it a chemical thing based on moods, or is it genetic?
Just wondering, and thanks for the answers.
