You might recall last month that I posted about my 3D-printed spectacles.
Enough people asked me for the files and for details on how to order lenses and mount them into the frames that I figured I’d release everything with instructions - and also redesign the hinges a bit so the temples fold more compact, something I meant to do for some time.
how much do lenses cost like this?
It depends on your prescription, the material you choose, coatings and such. The shape of the lenses or the type of beveling have no impact on the price, unless they’re highly curved with a step bevel for instance.
My lenses are standard polycarbonate lenses with a basic scratch-resistant coating. But I have astigmatism and I need progressives, so the lenses come out at $400. And usually I also order a pair for far and near (not progressive) and they’re like $200 per.
That’s the only problem with the registration tabs in my design: it requires notching the bevel of the lenses - meaning you have to work up the courage to bring a file to brand-new lenses you just paid a sizeable portion of your last paycheck for 🙂
