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).
People who wear glasses are screwed but not as screwed as people who rely on medication.
I have trained my children from a young age that, in case of zombie outbreak or alien invasion, I am to be left behind. I require far too many medications to function in a post-apocalyptic setting.
What oddly specific training. Is there a training regimen for a “Evangelion everyone got turned into Tang” situation too? What about the “Just got spider powers and a Canon event may be coming”?
They were young and zombie movies were everywhere. In the way of all children, the questions were non-stop. This was also the time I was bedridden, so I convinced them that zombies only went after healthy people.
The whole thing about Instrumentality is forsaking your physical body. Now, once you return to reality and realise your whole city is flooded like in the final scene, that’s when things start to go wrong.
My partner and I have discussed our wildly different willingness to try to survive in a post-apocalyptic world plenty of times over the years. He would work to survive and would probably thrive more than the average survivor. Me? I’ve always said I’ll likely head to the cough syrup section of the pharmacy.
This conversation came up earlier today, in fact. Well, I was recently diagnosed with rheumatoid arthritis. I’m still sorting out the right medication to get it under control and am dealing with a lot of pain, but way less than before starting treatment. I told him with this diagnosis, if society ever collapses in a way that causes me to be unable to get my medication? I’m out.

Hopefully if enough of these get distributed it won’t be so much of a problem except for people with astigmatism.

Joshua Silver, a professor of physics at the University of Oxford, first had the idea to manufacture adjustable lenses for the poor, removing the need for expensive equipment and professionals, in May 1985 after he had created a variable focus lens out of curiosity.
His invention allows wearers to adjust the glasses to their personal prescription without the assistance of a healthcare professional. They simply look at a reading chart and adjust the glasses until they can see the letters clearly.
The glasses use durable but flexible plastic lenses, which have fluid sacs filled with silicone oil between them. These glasses can easily be adjusted by the wearer by simply adding or removing some of the oil in the sacs.
The invention is not without its limitations, however. Currently, the principle only functions successfully with circular lenses, limiting the design opportunities. Additionally, the principle can only alter the magnification of objects, so the glasses cannot treat those with astigmatism. What these spectacles lack in aesthetics, however, they make up for in spades with utility and work on non-round lenses is already underway.
His stated goal was to make the overall cost of a pair of glasses as low as $19.
Holy shit this is amazing. I love inventions like this. This just oddly gives me a lot of joy. No need to waste hours on stupid eye exams, just adjust it whenever my eyesight deteriorates.
Awesome! But this probably takes forever to actually become a product that one can buy.

Original article I posted didn’t give a date, but the earliest articles about these glasses are from 2008-2011, so they’ve certainly been around for almost 20 years now.
I think they were really aimed at rural communities in poor countries, several of the articles I’ve read reference about 300,000 pairs being distributed.
You probably wouldnt want to buy it. They aren’t exactly a good fashion statement.
Well this is awesome but for me it wouldn’t work. B/C I’ve got an astigmatism.
Same, I have astigmatism and near-sightedness, a brutal combination.
We could rely on scavenging what’s already been made. Even if it isn’t your exact prescription, a little might be better then nothing.
I know of a YouTuber called the blind homesteader. He has family and friends help him. They have quite the homestead and he often helps the community around his homestead too.
Our modern life involves a lot of reading and writing and sometimes very technical work. But the work of surviving on planet earth is a little less vision intensive: farming, cooking, childcare, handcrafts. Depending on how bad your vision is you might even be slow and shitty at these, but people can adapt to a lot and figure out how to perform tasks they’ve done before, even with poor vision. Look at the blind: they can be functional. Yes there are things like hunting which you could. not. do. with poor vision but that’s why we live in tribes. Someone younger with better eyes will do that while you shell nuts all day.

Matt Murdock took that personally.
Casey doesn’t have bad dreams because she’s just a piece of plastic.
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
That’s pretty crazy.
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.
i feel like there’s some sort of childhood song about the dangers of silicosis we were supposed to learn but praise mandela didn’t
Silicosis sounds so silly!
Just saw a YouTube documentary that reminded me of this comment—it describes how Galileo made his lenses by hand from window glass using an artillery ball as a grinder.
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 will 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.
Do we have surviving scientists and engineers, or books? Then everything is easy-ish: Progress took time because we didn’t know anything, everything was trial and error. Now we know the correct forms of physical laws or their usable approximations so rebuilding is just a matter of time (generations maybe).
If somehow the collective wisdom is lost, back to the stone ages with you.
edit: High school education brings you to the 1920s tech (era of elements and alloys, just before composites) so maybe if we have any surviving adults, you can have glasses?
Maybe contact lenses are apocalypse proof
If people survive the “apocalypse” then glasses will survive too. You just likely won’t be lucky enough to get lenses that are a perfect match for your prescription.
6 out of 7 houses on my street have at least one person with vision problems. Between the six of the houses we probably conservatively have 50 pairs of lenses if you count all the old pairs people tend to hang on to. My house has at least 10 just by itself.
If you have or can scavenge a laser pointer, just go hog wild shining it all around in your eyes. You have nothing to lose trying it at that point and maybe you get lucky and give yourself DIY lasik.

You’ll have to hit up the local glasses stores. Luckily there’s plenty of em.
You’ll be okay, OP. It will be extra shitty though. Imagine running from a horde of cannibalistic raiders and you drop your glasses…
One would think that if most of society is toast there will be a shitload of left over glasses that could be collected and then distributed to those in need.
I have never put on a pair that was even close to my prescription. In fact, this post made me realize I’ve been wearing my old glasses all day and that’s why I have a headache.
There are always exceptions to the rule. There are people that have super special prescriptions and then there are other people that just have the standard stuff due to age, etc.
Based on that, the majority of people would have a pair that match them. Anyone else with special glasses would be shit out of luck because as the title says it’s the end of the world and only a few peops left.
Let’s not be ruled by exceptions to the rule. It is only a tiny amount.

If there’s that type of event, we (the survivors, that is. 95% of us will die) are going back, way back. When the elevator falls from the 21st century down to the 20th and 19th, the cable snaps and we’re going back to the ground.
See, even a hundred years ago, items like a light bulb or electric motor already depended on a very large supply chain and many people working together that never meet in real life.
How do you make glass? Do you even know what glass is, how many types there are, how to make it different thicknesses or shapes? And even if you can, can you make more for everyone else?
What are you doing in the meantime that you don’t have glass? How are you feeding yourself? With what?
Even if you think glass is “simple”, how would you get the materials and tools? The people who used to do that, where are they? What knowledge have they lost? Where is that material today?
In other words, you’re back to your bare hands and wits and whatever is in walking distance from you, right now.
Think you’ll survive long enough to worry about glasses?
