Here is the procedure as I understand it from the person who
made a custom correction from me.  Take your distance
correction and ADD 0.5 diopter to it.  Thus, my eyeglass
correction for distant vision in my right eye is +4.0
diopters.  The   correction piece to screw into my Leica is
+4.5 diopters. Works great. Of course, these stock
correction lenses do not correct astigmatism errors.  Hope
this helps.

I'm a little fuzzy on the question of selecting a correction
lens for the
M6 eyepiece. Is there a way other than trial and error to
determine which
one is most appropriate? The range of potential dioptre
adjustment seems
to be very broad and I'm certain that I fall somewhere in
there, but is
there a way based on my eyeglass prescription to tell which
one of the
alternative lenses would mesh best with the uncorrected

Thanks for your help. Probably a dumb question.
