If your problem is age-related inability to re-focus
your eyes, I've found a solution that has worked well
for me not only for being able to see the camera VF
sharply, but for being able to see sharply at all
distances from infinity to well under a foot: my
camera-eye main glasses lens is optimized for 1 meter;
the other main eye glasses lens is optimized for
infinity (the difference in correction is not great
enough to lose binocular vision except at first at
night); the non-camera eye bifocal (25-28mm flat-top,
set a little lower than usual) is set to pick up
sharp vision where the camera eye main lens leaves
off; the camera eye bifocal lens picks up sharp
focus where the non-camera eye bifocal leaves off.
Avoid "lineless" bifocals if you care about
wide-angle sharp vision, or easy use of a camera
viewfinder...
