Comment on Replacement prescription eyeglass lenses?
grue@lemmy.world 1 day agoI’m curious about what your costs are in actual dollars, although Trivex isn’t right for me because my R~x~ 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 them, 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.
