I feel like I have a deep reliance on society and technology, because I can’t fucking see without glasses and I’m too scared to do Lasik lol (also expensive).

You can make a rough magnifying lens by trial and error using glass and a hand grinder—not the same as prescription lenses, but for many it would be better than nothing.
Any glass? Any grinder? Can I find a broken window and start sanding it with sandpaper, as an extreme example?
Some glass is many sheets glued together, that could be trickier to work with
Thick glass that’s not tempered will be the easiest to work with
Pretty much any piece of glass and a series of sandpapers going from low to high grit will eventually work if you know what you’re doing
Yes, it’s not magic, it’s just the shape of the glass that makes the focus point of images be slightly closer or further apart.
Yes, provided you have a way to polish it back to transparent again, after changing the shape.
