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!
