Born from Aerospace, Perfected for Vision. Originally developed for bulletproof glass and astronaut helmet visors, Polycarbonate (PC) revolutionized the eyewear industry in the 1980s.
It is a thermoplastic material known for its extraordinary impact resistance—up to 10 times more resistant than plastic or glass. For safety eyewear, sports goggles, and children's glasses, Polycarbonate is not just an option; it is the responsible choice for eye protection. Jings Eyewear utilizes optical-grade PC pellets and precision injection molding to deliver lenses that prioritize safety without compromising aesthetics.
-------------- Why Choose Polycarbonate? ---------------
Polycarbonate is virtually shatterproof. Unlike CR-39 which can crack, or mineral glass which can shatter into dangerous shards, PC absorbs impact energy by flexing.
This property makes it the mandatory material for:
-------------- Manufacturing & Features ---------------
Polycarbonate lenses are created through Injection Molding, a rapid high-pressure process that melts the pellets and injects them into molds.
-------------- Addressing The Challenges ---------------
