I might recommend…
As you solely want glasses for studying, don’t take into consideration varifocals, as you don’t want the both the mid or distant parts. Go for old school bifocals. You can have zero correction for distant, and studying correction for the, ahem, studying a part of the lens.
When shopping for your frames, get one thing you could hinge up with the evf body.
I exploit the adjustment to set the evf to be used with out glasses.
I push them up and put the evf to my eye; they slip again to my nostril once I take the digital camera away.
I exploit the glasses for trying on the display screen.
It is far easier than it sounds and I barely discover it.
After some years of utilizing “computer” glasses (set to focus at virtually arms size) I presently principally use the pc with out glasses aside from small print. That’s as a result of I’m growing cataracts, that are altering my prescription, however that’s one other story.
I’ve tried varifocals a few instances and so they completely don’t go well with me. I’m proud of bifocals. And solely put on them once I exit anyway.
