Hi Tom,
   it does matter, if you wear glasses and want to make or buy a
   diopter eyepiece addon. Then, you must take into account the
   inherent diopter of the viewfinder when selecting the correct
   correction lens. As some people prefer having the correction lenses
   made exactly to their specs (1/3 D) than buying Pentax's (in whole
   D steps only IIRC), it's rather important to know beforehand you
   order it at the optometrist.

Good light,
