You like your eyes, right?  We certainly like ours.  Most of the time they work awfully well -- despite a massive design flaw that any first-year engineering student would have caught.

It's called the punctum caecum, an area at the back of the eye that the optic nerve passes through, obscuring the light-sensitive photoreceptor cells that make vision possible.

This neat little eye trick comes from Richard Wiseman.
