Dispensing Lined Multifocals 

They are certainly made with you in mind too. If I can't get the other opticianry educators to change their ways I'll let the consumers learn instead.

Coming up next I believe! If not then very soon.

Will you ever have a segment on how to read prism on a manual lensometer??? Especially on prism over 4 BU and/or out???

For amounts within the reticle we have videos on that and we do have illustrations on the website. Outside the reticle, not having worked with it enough myself, I'm no expert and even after 10 years of trying I never could find one to help us out. Best thing is to use an auto-lensmeter. Ask the lab to include the auto-lens meter ticket from their verification with the job and go on trust.

They are still made. They are still used, but are pretty rare (certainly here in the US). Most find a weak bifocal does the job as well as a trifocal.
