Dear Optiboard people,
Is there a Calculator program that is downloadable from some websit out there that will allow the calculation of spectacle thickness with the usual info i.e. size, power, index, CT, decentrn. etc.
So I don't have to go thru a big long physics formula :hammer:if I want to occasionally know the exact thickness of a lens for special purposes.
Ya'all are usually pretty sharp on this stuff.
Thanks,
dbracer
