I've solved this problem for me. I'm 64 so my ability to focus on different distances is somewhat limited. My eyesight is corrected by wearing bifocals which correct astigmatism, and allow good vision at infinity and at about 30-40cm. SLR camera viewfinders are normally set at 1m away (-1dioptre) which is where my spectacle corrected sight is quite poor. (Prices on supermarket shelves etc.!) I need to wear my bifocals when using my cameras. My solution is to fit eyesight dioptres moving the viewfinder image from the 1m position to closer to infinity. On my Canon cameras I've found a -0.5 dioptre satisfactory setting the image at 2m away, and on my Nikons a 0.0 works well. This puts the image nominally at infinity.
Hope this helps - I think other camera makes may use a different way of marking their eyepieces.
