My doctor was hesitant to prescribe me progressives given how difficult it can be to get used to them, and he spent a fair amount of the exam figuring out where to set the focal distance (had me hold my phone at a natural reading distance, had me read from a card at different distances, etc.). I have a very odd prescription, so that could have been part of it. Still, if it’s not too much time and cost, I’d go back and get the exam and get a prescription that explicitly includes progressive values.
Also, someone on HN talked about getting a prescription for reading up close (essentially the bottom focal distance of a progressive lens across the entire lens) and another standard prescription for non-reading use. When I have the time to get my prescription re-done, I’m going to do that instead of progressives. They’re a real pain to get used to, and they correct neither near nor far sight perfectly.
