Here's a job for Mike! The myotor bifocal is a plano margin lenticular myodisc bifocal(description for the younguns)........The field for distance, and near is dictated by the power of the distance and the near power, made by overlapping fields, thus creating an arc shaped junction.
Advantages:Custom field, and edge thickness control, base curve choice.
Disadvantages:Difficult to/custom fabrication.
Now heeeere's MIKE AUUUURRRIIIILIOUS!Eyes wide open

Neat, Harry.
Using a two-part epoxy to fill in the "bowl" between each surfacing operation will result in crisp lines of demarcation. You can also offer different segment sizes by tweaking the center thickness of the cut used for the segment bowl. Regarding astigmatism, you will definitely need to grind any prescribed cylinder power on the front suface of the lens blank with any minus lenticular lens design, which makes blocking either side a chore for surfacing the other.

I have a digital lathe and make stuff like that regularly in bifocal and SV form and can slab them as well. Allows us to do things that some of you used to do regularly on old equipment, just with more options. And easier. And faster.
As for benefits? Cosmetic mostly. Lighter weight.Aim at heaven and you will get earth thrown in. Aim at earth and you get neither. C.S. Lewis
