I’ve got some rimless eyeglasses bought years ago from Zenni that I love and that are in perfect condition w.r.t. the frame, but need new lenses. Zenni won’t sell me the same ones again for some stupid reason (something about reducing the allowed Rx strength on those frames due to customer feedback).
Anybody know a good place to get eyeglass lenses by themselves, so I can cut and drill the damn things to fit the frame myself?
(Note: I’m sure it’s possible to have a brick-and-mortar eyeglass shop do it for $$$$$, but I’m cheap, so no.)


I’m curious about what your costs are in actual dollars, although Trivex isn’t right for me because my Rx is so strong that I need a higher refractive index. I also appreciate that your 3D printed glasses link included a video about how the lens edging machine works.
Do you know of any other 3D printed frames that look… less Harry Potter-y?
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 my glasses, I can have a new one fresh out of the printer in 10 minutes.
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!
Ah, see, that’s what I was afraid of: Zenni is stupid cheap; the glasses I’m trying to replace were about $70. Granted, that was more years ago than glasses are supposed to go between prescriptions, but still, I was hoping for approximately an order of magnitude less cost for these DIY-cut lenses.
I like the idea of pillow-compatible glasses, but I already have a bit of resemblance to Harry Pottery that I’m not exactly looking to enhance. I tend to go for rectangular lenses.
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.
