Ok let me see if I can expane it a little clearer.
Yes the rangefinder PATCH is always in the same place but what you are really looking at through the viewfinder changes depending on whether you are close or far from the subject. So even though the PATCH is clearer with my glasses on at any distance the rest of the image is blurred at far distances. The rangefinder patch is superimposed over the top of the normal view. So even though the rangefinder patch is more in focus with glasses on at any distance the rest of the image is not at far distances.
At this point I'm not sure any type of correction lens will help getting both in focus at far distances.[/quote]

The rangefinder is set for -.5 diopter, so I would say you should try at least a 2.0 diopter on the viewfinder. They are additive, so -.5 +2.0=1.5. You might even try a 2.5. I think if you do so you will find everything from close up to infinity will be in focus for you. I also had perfect eyesight until I was 50, and can still pass a pilot eye test (lots of squinting, however). However, I can't read a book at normal arms length. With 2.5 diopter glasses everything is perfectly in focus. I therefore use the +3 on the M8, along with the 1.25 magnifier. Perhaps your dealer can allow you to try out the various powers to see what is best for you. You should be able to find a combination that will work for all distances without glasses.
