About half way through the evening, I noticed I'd forgotten to put the carpet on the monitor cables. As I grabbed said carpet, suddenly my left eye went really blurry.
I then spent some time trying to get my left eye to tear some, so I could flush whatever was in it.
It wasn't until I took my glasses off to rub it that I realized that the left lens had fallen out.
I gotta say, searching for that was a lot of fun.
OK, back to the attempt to sleep...
