    Help identifying lens

    I need help identifying the manufacturer of a progressive lens. These are are the engravings:

    O
    BR 150
    L

    P2 G



    I should not of course that the 'G' is backwards. I appreciate any help you could spare. Thanks!

    It is the reverse 'G' (low temporal) that I am trying to figure out. I cannot seem to find the manufacturer mark in any reference catalogues. A bit of a back story, these lenses were supposed to be from Rodenstock, however, the engravings don't seem to match any of their current lines.

    It might be a Rodenstock if there is an infinity symbol and/or an R at the temporal marking. If not, it is probably a house brand.

    The 53 should be indicative of trivex either way.
    Have I told you today how much I hate poly?
