You ain't seen nothin yet - especially when it's dark.  We have glasses with lights on them and they are terrific.  Great for reading in bed, reading a menu in a darkish restaurant, or reading the theater bill - they're really handy.  The Book Bin is  terribly tricky - we'll have you reading day and night.  Be sure to try a pair back in our store room - it's dark.  You'll be amazed.
