All you'll need materials-wise is your old pair of glasses (as long as the lenses are still good) and a pair cheap reading glasses from the dollar store. Get the "Rimless" kind of reading glasses, where the bridge and arms are connected by screws drilled right through the lens.
For tools, you will need:
- Mini screwdriver set
- Dremel or drill
- 1/16" drill bit
- Fine tip sharpie or very sharp awl
