“During the early period of the production of eyeglasses, they were referred to as vitreos ab oculis ad legendum (eyeglasses for eyes for reading)...”

Guess they wanted to make sure nothing was left to chance.


It has been a long time since high school Latin, but a better translation might be "glasses for eyes for reading."


A less wooden English rendition would be "glasses so that eyes can read" or, actually, probably better "glasses so that those without well-working eyes can read".


Or even "thing made of glass for eyes for reading."


Why "ab oculis" instead of "ad oculos", though?


Literally, "without eyes". Without working eyes, anyway.


Shouldn't that be "absque oculis" instead in that interpretation?


> From an earlier orbus ab oculīs ("deprived of eyes").

> (Late Latin) blind

I don't think that link to "ab oculis" is relevant. I suspect that "ab" just means something like "on, in front of" in this case: "glasses in front of the eyes for reading".

If you have time, check this article for the various possible meanings of "ab": http://www.perseus.tufts.edu/hopper/text?doc=Perseus:text:19... (It's a bit more detailed than wiktionary!)


OK, I dug out my old Cassell's. And I stand corrected. It's "glasses in front of the eyes for reading".


I love how there are so many Latinists here :)


Hey, Latin was my third language :)


I'd say "glasses for the blind to read"


When you look at the Latin, do you see a repeated word?

We call them "eyeglasses" in English. The Latin word vitreos doesn't have "eye" in it, it's just "glass". It's also the clear stuff in the middle of your eye, but that's a much less common usage than glass.


Amazing that glasses was invented almost thousand years ago, and today it is still that overly expensive item.

I only need glasses since the last year or so and I have been amazed by how monopolistic and bad this whole industry is.

The prescriptions are fairly standard, but still, making a pair of glasses cost more or less 200$ and require a 1:1 appointment. The price of the lens mounts is just ridiculous for a piece of metal.

Even looking at an alternative like Warby Parker, the price is still about the same for something, that let's be honest must not cost more than 20$ to make!

I since then bought 4 pair of glasses directly on Amazon from a Chinese vendor for 10$ (I have a small standard prescription) and they do a perfect job. I can barely tell the difference from my Warby Parker ones.

It's crazy to me that cheap glasses are still that difficult to get.


Most eyeglasses cost under $10 to make, lens included.

It's still an expensive item thanks to the near monopoly of both frame and lens production. Nearly every brand you know are owned by just two companies. Those two are now merging: https://www.theguardian.com/news/2018/may/10/the-invisible-p...


Excellent example of the “free”economy not working toward efficiency and actively working toward concentration. We really need more,checks and balances.


It's easy. Go start a glasses frame and lens company and sell them for less. There's nothing at all stopping you.


Yup.

The Freedom Markets™ cult perpetuates the fiction that corporatism == capitalism.

Corporations are explicitly anti-competition.

Depends on the country. I went to Japan for vacation a few months ago ; my girlfriend wanted a new pair of glasses. She just went to a mall in an optical center, they took her eye measurements on the spot, we went back two hours after and the glasses were ready.


I did the same when I had to travel to Moscow the day after I had lost my glasses in the ocean from a boat.

Going into a shop in Stockholm I was told it'd take 2 weeks, which obviously wasn't acceptable.

When I arrived in Moscow, just like you I went into a shop, took the measurement, went for lunch and it was ready when I came back. What was fascinating was that they had the actual machines to grind the lens at the back of the shop. It was pretty cool.

Those glasses lasted me for years, and they worked really well.


Quick glasses are very common in developed countries. In the U.S. at least you can find a Visionworks or a Lenscrafters (or similar) pretty much anywhere and their hook is "glasses in about an hour". They usually have an optometrist in the store so you can get prescriptions there.

Some newer companies (Stanton Optical) are even starting to offer the complete service inside of 15 minutes so you can get the glasses while you wait and frames run as low as $20.


most apothecaries here in Italy have a section for cheap glasses. worst scenario you have to buy two and mix the lenses.

if you have special issues and need to order lenses it may get expensive but glasses are deductibles, so you get a little back.

anyway I did a cursory search on amazon usa and one can find prescription glasses with lenses of variable strength for around 20$, of course they're not the best or the prettiest, but there are ways for people to get glasses on the cheap.


Try shopping for a pair of prescription sunglasses. Cost me 600+ euros (EU) for a pair of decent shades, while my gf just picked some up for a tenth of that.

One of the happiest moments in my life was when I realised that speedo offers optical goggles. And even not trying to rip me off 10x. No more fumbling around at the pool.


I wonder if part of it is that psychologically people want expensive glasses because they value their vision and want to look cool? I use a 99p pair of reading glasses from the pound shop and they actually work surprisingly well and look ok.


It's sold as a fashion item now. Why else would pro athletes with superb vision wear fake glasses? Handbags also cost little to make, same difference.

Would you mind sharing a link to the vendor where you got the Chinese glasses?


Not the original commenter, but my wife and I have had several pairs from http://zennioptical.com and been very happy with them.

(And speaking just for myself, I'd prefer not going through Amazon if it can reasonably be avoided.)


I love Zenni. I buy glasses from them quite a bit just for a change of look. I think the cheapest I've been able to buy them for so far is about $10.


Seconding the Zenni recommendation.

Did they know about the law of diffraction, or did they just grind the glass until it had the desired effect?


Eyes of glass in twin hoops!
