Time to put on your thinking caps.
We all know how to calculate MBS for SV finish. I have been scouring the web for a definitive method to calculate MBS for multifocals and have come up with nothing.
I know how, but want to present a WebEx for our opticians and lab staff without creating one from scratch. Videos, PDFs, Powerpoints, all are welcome.
Anyone up for the challenge to provide links?
