I just wear my glasses. If you can't tell if it's focused with your glasses on,
does that mean you need new glasses? Also make sure you're looking through the
middle of your glasses, as the edges may cause distortions.
Looking through a viewfinder with glasses on is annoying because you can't see
the edge of the frame, but if you need them to see birds, what choice do you
have?
I've added a 1.3x viewfinder magnifier, which helps with manual focusing, but
makes it even harder to see the edges.
