I've always had large astigmatism corrections in my glasses. It's enough that
switching between two pair of glasses it difficult.
I have a pair of single vision glasses for every day wear and take them off to
read. My next pair will most likely have to be bifocals because whenever I
have to read a map or directions I have to pull over to read them.
What I did was once I ended up with glasses that work for me I adjusted the
diopter on my OM4 until I could focus the screen. I have enough problems
trying to get one pair of glasses to work let alone several. I still can
focus most cameras but I'm not quite 48 yo.
