    Polycarbonate

    I am having an issue with my staff selling premium products. Does anyone think polycarbonate is a premium product? I say there are too many inherent problems with the product that you don't get with Trivex, 1.56, 1.60, 1.67. Any thoughts would be appreciated.

    Polycarbonate is "premium" compared to...uncoated CR39.

    It's a word game.

    I have used it almost exclusively for about 25 years without any real problem, optically.

    Truth be known, though, I would consider it "a standard material" but the industry doesn't.

    1) Lowest density, lightest weight, ophthalmic lens available.
    2) The only ophthalmic lens that doesn't chip or crack.

    Need more proof?

    Low chromatic aberration, high strength, available in almost all PAL designs.

    No disadvantages except for high dioptric values in improperly sized frames.

    That makes it premium in my book.

    I have no financial interest in PPG or any of its subsidiaries and affiliates.
