Any videos out there for teaching how to read prism in progressive lenses?

[JohnMcGowan]

Howdy,
I need some help please....
just checking to see if anyone here has any video links for teaching people/ophthalmic techs how to read prescribed as well as un- prescribed/unwanted prism in progressive lenses that I could borrow from them? Also is there any written material available on this subject that would be useful for techs who may not have the thorough understanding on how to read prism in a lensometer?
I will give the author full credit for the material.
I appreciate any input you can offer.
John

John,

Chapter 6, Ordering and Verification, has a thorough explanation with illustrations.

The other 23 chapters will keep most of us up all night.

Hope this helps,

I don't believe that it will help much in reading Prism in a PAL. I'm looking at how to attach it here.
