Before my eyesight degenerated to the state it is now, I discovered a useful trick.  Making a fist and peeping through the hole helps you see more clearly.  These glasses from Kamigu are based on that very idea.  While  they look like a strange fashion statement, they are actually a very serious tool as the 1mm holes allow you to focus without lenses.  The glasses are intended to temporarily help you ride out a crisis when your glasses are broken in a disaster or accident.
