I wonder if the no they can't do it is the same no you can't use it when trying to use samsung pay on a non-nfc terminal just before proving how wrong they are. the instructions that came with the frames seemed clear enough.
Funny thing happened to me...... I went to first one medium sized chain. Said would do it but I would need to sign release. Not thrilled about that, asked if after exam he would give me script for lenses said yes he would. Scheduled an appointment 5 days out. Than went to small shop that I went before he was like no way looked at frames said don't want to be bothered with them. So figured I would wait to get the most from my insurance for the lenses and wait 5 days. Afternoon before my appointment I get a notification that they are cancelling all appointments till further notice due to the virus.
Great that is now 2 week min wait time just for exam. I went online to lensesrx, didn't have physical script for prescription but had my current numbers documented. I figured I want to use them for now and for the money they are a backup pair of lenses if needed. Or maybe will 3D print another set of frames for the lenses later lol. Well I ordered and picked 2 week shipping because of other comment on how fast they are. I got mine just under a week took like 30 seconds to put on each lense. Didn't come with instructions but still very very simple there are even YouTube videos of needed for it. I ended up getting the standard lenses for Amazon echo $45 but ended up adding the HD option for $40 giving shatter resistant, scratch resist, UV protection, and anti reflective plus 10% off. So not too bad was nice being able to see so clear though the echo frames. Lenses are so light weight also about the same as the lenses that came with it.
So if you need lenses and have a script or atleast know all your script numbers grab them through lensesrx.com if you pick 2 week delivery you could get them in half the time. You pick quick might get in days.
