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?
