If I ever need to buy slate, I will make extra-sure never to buy it from Porto Slate Importers.

It really depends on your prescription. Mine will never come cheap. Even hard-discounters will charge me an arm and a leg for the correction I need.

My prescription is fairly complex - astigmatism and progressive correction with funky-ass zones. And I usually order them extra-thin -which Trivex just about allows in my case - so my glasses are as light as possible (my current 3D-printed pair weighs 11 grams with the lenses. And I have anti-scratch and UV filter coating.

My last pair of lenses cost me 300€. Not cheap, but it’s kind of a one-off as long as my vision doesn’t change and I pay attention never to wipe them with anything other than a clean microfiber and lens-cleaning fluid, to avoid scratching em. If I break the frame, which happens every once in a while when I sit on them, I can have a new one fresh out of the printer in 10 minutes.

Do you know of any other 3D printed frames that look… less Harry Potter-y?

Hehe sorry, I’m addicted to that shape - not for the style, but because small, round glasses are the type of glasses that sit closest to your face, so you get a huge field of vision with small lenses, and you can rest your head on a pillow without breaking the temples. No other style of glasses gives you that. Round lenses aren’t ideal if your correction is oriented - astigmatism - but my design has an anti-rotation notch.

I would suggest you design and model your own frames if you want another style: it’s not super-complicated and it’s really rewarding to wear something you created yourself every day!

Bricks-and-mortars can order lens blanks and edge the lenses themselves of course, if they have the edging machine. Older shops still do it. But modern stores just don’t bother anymore: they send the order to whichever supplier they use - often ordering the lenses from one supplier then having them shipped to some el-cheapo country like Vietnam for edging, which is why it takes weeks to get new glasses.

Modern opticians are little more than sellers of overpriced frames, which is why I roll my own. They make money on the frames and lose money on everything else, including fitting. You know how I know that? Because most shops will actually charge you a flat fee if you bring your own frames - including if you do the fitting yourself like I do. It’s properly outrageous.

No, Hoya does it. I send them a 3D-printed template for their lens edging machine. It’s in the README under Ordering lenses.

I 3D-print my own frames so I only buy the lenses. I get mine from Hoya because I find their Trivex lenses to be the best. But I can’t order from Hoya directly, and to my knowledge, none of the lens manufacturers deal with customers other than opticians and optical stores.

I get them from my local Optician. I made it very clear to them that I’m only coming to their store to get the lenses. I don’t need their services: all I need them for is to order from Hoya on my behalf. They play ball and only take a minimal cut to cover their time processing the order.

Trump and his peculiar idiocies will be gone soon enough. Even if his fascist posse stay in power, I don’t they have any particular beef against renewable energy. The industry will be fine.

The white supremacists are super-confused now that the Israeli are more Nazis than they are.

Oh that’s easy: nothing gets popular on Reddit ever again. Reddit shuts down, the myriad of AI training data vultures it feeds are left hungry and Spez dies destitute.

This is Prusament PLA dissolving in acetone in seconds:

I’ll come back to it in 30 minutes and it’ll be a messy soggy half-dissolved thing. And it’ll be fully gone within the hour.

you’re sure as hell not able to dissolve PLA in acetone

Why don’t you try it before saying that?

Have you even tried it instead of talking out of your ass?

I use acetone to assemble PLA parts and polish them all the fucken time.

I used acetone to chemically-polish a PLA part this very afternoon. But if you say so 🙂

Acetone dissolves PLA. You can use it for chemical polishing but also for assembling parts.
