Need glue

[chip anderson]

I am in the process of making a pair of Franklin bifocals from CR-39. The problem, while these work well without adhesive, I would like to have an adhesive as a sealer between the distance and near portions of the lenses (not an optical surface). Anyone have any suggestions of a good adhesive/sealer for same?

Also for future reference would like to know if anyone know of same for Poly and Trivex(polyurathane).

I haven't heard of any one making Franklins since I was an apprentice. Used to make them out of glass and use B&L lens cement.

Would suggest the epoxy to join CR-39 and others.

Let us know the outcome.
