Unless there is a condition I am not aware of, in which some humans have snail-like eyes, none of us have ever really seen our faces. Yeah, Yeah we have looked in mirrors, seen pictures of ourselves, seen videos of ourselves. But you were looking at your reflection, your likeness on paper, or your likeness reproduced on celluloid or digitally.
This doesn’t really have any consequences as far as I can tell. I highly doubt that mirrors, water, and many types of recording devices are lying in terms of representing the way your face looks. I just thought that was an interesting thought. Never will I gaze upon my own face without a medium. Never can I stare into my own eyes directly. 😛
