In eye wear, you get what you paid for.
I do not need reading glasses as I am near-sighted but the top line lenses I have are so much better than ones I got at a cheaper eye glass places, the money is worth it.
The low buck vintage frames I have used for decades, the ones that have gold in the frame, the supply is near gone now; I wish I had bought a dozen when they were ten to twenty bucks at antique shops twenty five years ago.
