My tan

I just noticed the strangest thing: I have a tan line from my glasses. Not the goofy sunglasses tan that you sometimes see on people where there's a raccoon ring of pale skin around their eyes. Rather, it's very small, specific white ovals where my glasses rest on the sides of my nose. Do any of you other four-eyes have this?

On the bright side, this confirms that I have a tan, that I'm not as debilitatingly white as you might have thought!
