OK, so here are the new glasses, picked up a couple of hours ago at the glasses shop. They seem to be working well, unlike their previous half dozen or so predecessors.
I went for the bigger lenses this time because the only pair of glasses I had prior to these that I could see out of with any degree of consistency is a pair I bought maybe 15 years ago. They're big "old man" glasses.
More recently, I have preferred the slim, horizontal dealies that are trendy and damn near useless if seeing is the goal.
I like these. I hope I like them two days from now.
