Hi There,
I was wondering how is possible to recognize the lenses that you got
is 1.70 or 1.74 and be sure that my optician havn't done any mistake
or so ...
I would appreciate any feedback.
Michel.

If you have a progressive, then there are etchings on the lens that would
indicate the material, in addition to manufacturer/model and add power.
