I've been using Zenni Optical for several years and they are great glasses for a reasonable price.
My last order in late August 2020 was two pairs of complete progressive (what used to be called bi-focals) glasses for my wife and one frame only to fix up a pair she already had that the frame was broken on.
Grand total including shipping was $91.23.

I would encourage Keith (or anyone who wears glasses) to pick out a frame and order a pair of glasses to have as a backup to the glasses you already have. It's cheap insurance for when you break or loose your everyday glasses. I don't have stock in them or anything, I'm just a satisfied customer.
