Aaron Porterfield created two tutorials which I as a eyeglasses wearer appreciate. He (and I) often brakes his glasses so here is a solution if you can use some CAD software and have some equipment.

Here is detailed tutorial on how to 3d scan prescription eyeglasses lens by taking photos of a lens covered by masking tape:

There are a few simple(ish) steps involved, but nothing an average user can't master ...

Great work Aaron!
