The arrival of eyeglasses in medieval England

Eyeglasses’ Arrival: How Immigrants Transformed Medieval England’s Vision. Eyeglasses can be considered one of the most important inventions of the Middle Ages. A recent study shows that by the 1440s people in England could buy their own spectacles, thanks to a group of immigrants living just outside of London.

so, by late 1400s, a high end commerical pair could set one back 18 shilling roughly £561.96 in 2017. " time when a middle-class stonemason was earning about 17 shillings per day.*  Spectacles were becoming attainable by the middle class."

My favorite story from that period is the artisan who tripped, fell into the lens-grinder, and made a spectacle of himself.

Eye can see that.

We've really lost something when you no longer find Spectakelmakere as a last name.

Spectakelman indeed! What a fine name.

There's a Brexit joke to be made here, but I can't quite see it.

I feel like anyone who complains that people shouldn't wear glasses in shows that take place in historical periods can kind of bug off for anything starting in the 1400's and on.

Occuexit.

Nearly £150k/year in 2017 money? That's a bloody rich stonemason...

These were all reading glasses, which would have been a (literal) godsend to all those religious scholars poring over closely written texts under inadequate lighting, let alone artisans doing close work (if they could afford them). They effectively extended the working lives of anyone whose close vision began to fail with age, and they couldn't possibly be of the devil since so many saints wore them!

I'm asuming here that glasses correcting for short sight were developed much later, since while reading glasses only need a simple convex lens to give some improvement in sight, correction for short sight requies concave lenses ground more precisely. I haven't checked this, but I'm thinking late 19th/early 20th centuries.

You're right, they did come later, but not that much later. From another article on medievalists.net, linked from the article: "These early glasses featured convex lenses to help the farsighted focus on items up close. Concave glasses were invented in the Early Modern period."

Very cool - I had no idea glasses were invented so long ago, although I guess they were nothing like the lightweight, super-accurate devices capable of correcting for complex prescriptions we have today.

Yeah, today's glasses are okay, but do they have heavy wooden frames that fold up like scissors? I think not.

As a modern optical lab technician (such a less exciting trade name) and nerd, the history of the actual innovations and inventions involved in my work often pale in comparison to the societal and individual history of what it felt like and was considered by others to be a 'glasses wearer'. In short, prior to the very modern era it absolutely sucked, like in every way you can imagine.

Material quality was far worse, the best glass produced in those centuries would be laughable today if we didn't know what damage it can cause, comfort was non-existent, tons of basics about fitting and prescription did not exist. We are legitimately talking about strapping basic magnifying lenses to your face. These things were not popular, they were devices used for very specific purposes, and the blunt and grim reality is that folks with what we'd now consider pretty simple visual acuity issues probably weren't making it to a point in life and society where 'affording optical care' was an option.

I'd like to take this opportunity to thank everyone ever involved in making corrective lenses more widely available. I've been wearing glasses since I was five, and my vision has gotten so bad over the intervening years that I'd be useless with them now.

And by 1600 they'd spread to Japan, which shows how rapidly people adopted glasses since Japan was pretty darn closed off back then. There's a memorial to eye glasses being brought to Japan in Ueno Park.

And yet despite glasses being around since the 1400s for whatever reason no one figured out ear pieces until the 1700's, which is just staggering to me.

Which also makes Mizu's glasses in Blue Eye Samurai anachronistic. Glasses did exist in Japan at that time, but not with rigid ear pieces.

Interesting article!

I watched the linked video. Did anybody else who watched it find the narrator's voice to be extremely uncanny valley and just... odd? If it's computer-generated some really weird choices about how to sound human have been made, but if it's human-generated it sounds like someone trying to sound computer-generated.

For the record, I don't expect at this point to be able to consistently tell the difference.

Consistent metallurgy with non-reactive alloys, is the core answer. There are a lot of problems involved with what materials can comfortably and safely sit on the face for hours, and getting metals that thin yet strong isn't easy. These are expensive items and no one wanted them getting broken easily, and think of how often stems break even now.
