I … go to a glasses store? They still have independent stores, and there are chains inside Walmart and Costco and probably other places I’m not thinking of at the moment. They generally do minor repairs for free

So, if you mildly damage your frames, like get one arm out of alignment? You can bring your frames into most glasses stores and they’ll do their best to re-align the frames for you (with the caveat that if something breaks, they’re not responsible). If you lose a screw or need your glasses tightened, they’ll do that too if you ask them. I’ve never been charged for doing this, and none of them have actually broken any of my frames.

If you have a simple® prescription and break your frames, you can walk into most glasses places and ask about replacement frames. They’ll almost never have identical replacements - glasses “fashion” moves on too quickly for that - but they’ll often have something similar that they can fit the lenses into. Sometimes they’ll need to trim the edges of the lenses a bit, and sometimes there may be little gaps between the frames and the lenses, but you can absolutely do that. When I’ve done this (longer ago than I’ll admit), they only charged me for the new frame.

I have a stronger prescription these days, and glasses “fashion” still moves faster than I do, but unfortunately my prescription is now strong enough that it’s partially based on the distance of the lens from my eyeball, as well as the angle the frames sit on my face (there’s a prism in one lens). So trying for the “eh, find something close to this broken frame” game doesn’t work for me anymore. Thus the second pair of empty frames. If I break my old frames, I’m absolutely positive I can walk into most glasses places, say, “Hey, these frames broke, can you please move the lenses to these identical frames”, and they’ll be like, sure, no problem and no charge.
