WebView history Polycarbonates ( PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. WebApr 14, 2024 · Trivex lenses are typically more expensive than polycarbonate glasses, but by just how much varies from case to case. There might also be a disparity between different versions of polycarbonate glasses. There is a wider range of options for polycarbonate eyewear, so you can expect to pay more if you have additional needs for your prescription.
