If you know your old prescription, there's a few stores that have varying strengths of reading glasses, non-prescription. Most of them have the same strength for each eye, but are useable until you can get a new prescription. Used a pair of Dollar General glasses when mine broke on a Telluride vacation years ago
If you actually do have an active prescription (I'm assuming this isn't the case) or can get your optometrist to write a note/ COVID exemption, there's overnight/1 day shipping from several online retailers where you can use various lenses combined for under $100, and they can be rushed overnight.
Glasses.com had an ad a bit back for people whose healthcare was delayed due to COVID restrictions on office visits etc.
You could probably get someone to help you if you called them, and explained the situation.
