Why is the focus set to infinity?

It has been suggested that one mask the aperture 
with a thin piece of sheet metal with two holes 
punched in it.  When the two images are superimposed, 
the thing is focussed.  Of course that means outer 
zones are in focus and you may be more interested 
in the central part of the lens.  I wonder if it 
would be good to put a red filter over one punched 
hole and blue over the other.  I've never tried 
this stuff but it sounds cool.
