    Thank you.
    Too many “opticians” only see higher indices and expect them to be better, with zero to little knowledge of the actual properties of the material.
    High index means I can sell a...

    Many materials are now available with UV420+. IMO, offices use TVX b/c they can charge more. I know of no office that sells TVX for the same price as poly or CR, but many no longer charge extra for...

    167 is not much better in terms of ABBE over Poly, fight me....

    Poly is stronger than Trivex, especially after AR is applied, in terms of impact resistance at the same thickness. Trivex is more chemical resistant, lighter overall and has higher tensile...

    I run a full service lab. Trivex is no more difficult to work with than poly. Surface macros are basically poly macros. Edged settings are basically poly setting.
    Trivex is tougher on wet edger...

    Deleted my response. I stayed up way too late, and misread the question myself, or got lost in the thread. My bad.

    Agreed that TVX is overused, but considering its specific gravity and impact resistance, for low to mid RX, it fills the need very well. 3 piece, nylor, sports and safety, TVX beats CR39 hands down....

    If the repair can be done in house, there is no charge. We do not solder, nor use hot fingers, so if anything has to be sent out, we charge enough to cover expenses, if the frame is out of warranty.
