    Hi Mike, This is the literature on the lens packaging.  Do you think
    this is inaccurate information? 

    "Omni-View allows you to see more and do more.  You see more in
    clearer, natural colors.  Do mre because it reflects most of the heat
    and infrared generated by an arc thus keeping your eyes cooler, more
    comfortable. Omni-View is made of breakage resistant polycarbonate
    which is one-third the weight of glass. 

    Available in all conventional sizes and shades.  Substituted
    shade-for-shade gives protection equal to green glass.  Increased
    apparent brightness in shade-for-shade trade-off is non-harmful. 

    Care Instructions:  clean with any commercial lens solution or soap
    and water.  Always use a clean soft cloth.  Avoid scratching or
    removal of gold coating. 

    Meets or exceeds all ANSI Z87.1 standards. 

    Certified model Manufactured by:  Gentex Optics, Inc.  Carbondale, PA
    18407" 

    Please tell me what you think. 

Thanks,
Donna
