I have myopia combined with astigmatism and age-related inability to
focus. (The astigmatism makes a diopter inserted into the camera
eyepiece impractical, since correction would be wrong with a 90 degree
turn of the camera for verticals.) Since I find tri-focals too awkward,
I had a pair of glasses made that corrected for four distances by
alternating corrections between the main lenses and the bifocals - which
has worked very well (infinity correction for non-camera eye, camera VF distance [about 4'] for the camera eye, next closest distance for the non-camera eye bifocal [25mm flat-top, set low], and the closest distance
set for the camera eye bifocal). It took about 2 weeks to feel comfortable
with night driving and movie watching, but for everything now,
continuous sharp focus has been restored, and I can see the camera
VF very sharply again. I highly recommend this solution - but be careful
with night driving at first (my camera eye, set for about 4' focus,
wanted to take over sometimes when subject detail was not sharp and
contrasty...). BTW, I consider a sharp VF GG screen (alas, newer ones
are getting worse...!) sharply seen (with good eyeglasses corrections)
still the easiest and most accurate way to focus (and it is good
enough to clearly see the AF errors that occur much of the time with
most AF camera focus systems).
Hope This Helps
