You can't get anywhere close to 3D printing lenses

  But there is a good point there--Zeni optical probably pays under $4 per pair of lenses it sells. If you had a slot to insert a lens it wouldn't be very expensive.

  Not as 100% of the process, but you can print a blob that is 90% of the shape of your lens and grind the rest of the material away as you would have to with normal lenses. I've seen people do it. It's labor intensive, but less so than starting with a regular lens blank.
