There was something missing in your eyes - some primeval light, some lifeforce telling that you were actually there. You weren't. Not anymore. Your eyes are now dull and lifeless, unable to gaze or stare, glancing through everything without focus or purpose. They seek nothing no more. They see everyone but recognize no one. They are empty - you are gone, and it's just as if you've left your body behind without shutting down, alive but lifeless.
