Eye glasses started showing up around 1300 AD. Implies the basic tech / processes required to make them is relatively simple, given that they’ve been around in some form ever since the middle ages. Granted, they wouldn’t be as sophisticated as they are today, and many people with very niche issues would suffer.
Anything more modern, requiring microchips or heavily integrated international supply chains would go poof. Personally, I’d worry about dental and medical stuff we diagnose with x-rays. Like it’s not too uncommon for people to have a root canal these days… but it didn’t become a more ‘common’ thing until around the 1800-1900 period. Hell, getting your wisdom teeth pulled in a post-event world would likely suck some serious ass.

The way glasses worked in the beginning though was that you’d make a bunch of lenses and people would try a lot of them until they found one (or two) that let them see a little better.
It wasn’t anything like what you’d expect nowadays.

That’s how it would work in a post apocalypse too. People who wear glasses right now are typically on vision plans that allow for a new pair every year. I have like 5 old pairs, 4 of which no longer are really strong enough.
So depending on how far down the road post apocalypse you either randomly go through houses until you find a pair good enough, or if enough time has passed there were almost certainly be people specializing in selling glasses and medical things.
Now if you are far sighted all you have to do is walk into any abandoned CVS and go look through the huge rack of cheater lenses they have.
