I wondered about the bifocal thing. Looking through the mirror you would focus on whatever's off in the distance (even though it's behind you), and even though the mirror is close to your eye. So you would need to use the upper distance lens in your glasses. Good thing, huh!
That is a good thing!

I've only been wearing glasses since August, and I went straight to bifocals. I wonder how many more of these unanticipated "adjustments" I'm going to have to make! lol.

Thanks!
