    Essilor Airwear

    Received an information package from Essilor today focusing on their Airwear (polycarbonate) brand of lenses. The pamphlet claims polycarbonate is "5 times more impact-resistant than Trixex". I was under the impression the opposite was true; that Trivex had the edge on polycarbonate in impact-resistance testing. Any lab gurus or other technically-minded folks have a definite 100% answer?

    You may start with some great information here. Sadly, Pete doesn't post much around here anymore - and no one could blame him with the anti-E sentiment which permeates many of the threads. He brought some valuable info to the discussion.

    Here's a link that states the differences between airwear, (polycarbonate) and trivex. Both have similar impact resistance however the trivex is a lighter material and has a superior abbe value. Hope it helps.

    Trivex also has superior scratch resistance and great tintability (when surfaced). Although Poly is cheap (cost & quality), it is inferior in many ways and is old technology. It's hard to believe that some of the largest global lens manufacturers still attempt to spin it through lame marketing campaigns.

    Even better is the new HiVex material - a 1.56 mid index Trivex stock hard coat that is tintable!
