    Aha! I just got one of these for my lab yesterday. I've been wanting one for a couple years, but hadn't taken it upon myself to go get one. You can go to a hobby store and pick up a paint pen--is this the same thing you're using? A little bird brought one to me, and it was like Christmas in Optical. I was just tickled. It's much better than a china marker for in the lab.
    It's nice to be important, but it's more important to be nice.

    To me, at least, that proves Trivex slightly superior in impact resistance.

    Note the little piece of poly breaking out and flying out below the lens and to the right. After being pierced, unlike the Trivex.
    Hehehe - PPG marketing at it's finest! :D I'm sure that any poly manufacturer could have made the 'same' video and shown very different results. And frankly, with the size of that giant steel 'projectile' they show, I don't care if you're wearing poly, trivex, CR, glass, kryptonite, diamond, unobtainium or ANY lens material at all - I highly doubt a kevlar bullet resistant vest would offer much more protection - the shatter resistance of my lens would be the absolute LEAST of my worries since all of the bones of my face would be summarily shattered. :shiner::p

    As to the marking pen, look up the Staedtler Lumocolor permanent "Special F". I think Hilco and Grobet carry them for a few bucks a pen. Available in black and red when I last looked. They'll mark on just about anything, but be sure to get the "F" designation. The standard permanent variety don't work well on the new super slick hydro/oleophobic surfaces.

    The Staedtler F pens Are The Ones To Use for that.

    But since even seeing isn't believing for you try this one too. If shatter resistance is of zero importance to you, then surely tensile strength should be a factor.

    Tensile strength is always nice sure...except that the Trivex stuff was beat by the 1.60 and very handily spanked by Essilor's 1.67! :shiner::p:D

    It's all good these days, and frankly just so long as I don't have to do glass every other job, I'm generally a happy guy! All the best Dragon my Man! :cheers::cheers::cheers::cheers::cheers:

    Of course that means poly was spanked also.:cheers:

    And we do about three glass jobs a year. Mostly drill mount.:hammer:
