Ilensi yeresin luhlobo lwelensi yokubona eyenziwe ngentlaka njengemathiriyeli ekrwada, ecutshungulwayo, idityaniswe kwaye ipolishwe yinkqubo yekhemikhali echanekileyo. Ngelo xesha, i-resin inokwahlulwa ibe yi-resin yendalo kunye ne-synthetic resin.
Izibonelelo zeelensi ze-resin: ukuchasana kwempembelelo enamandla, akulula ukuphuka, ukuhanjiswa kokukhanya okulungileyo, isalathisi esiphezulu se-refractive, ubunzima obulula kunye neendleko eziphantsi.
I-lens yePC luhlobo lwelensi eyenziwe ngokufudumeza i-polycarbonate (i-thermoplastic material). Esi sixhobo siphuhliswa ngokuhlola indawo, ngoko ke ikwabizwa ngokuba yifilimu yasemkhathini okanye ifilimu yasemajukujukwini. Kuba i-PC resin iyimathiriyeli ye-thermoplastic eneempawu ezigqwesileyo, ifaneleka ngakumbi ukwenza iilensi zokubukela.
Izinto eziluncedo kwiilensi zePC: I-100% imitha ye-ultraviolet, akukho tyheli phakathi kweminyaka emi-3-5, ukuchasana kwempembelelo ephezulu, isalathiso se-refractive ephezulu, ukukhanya okucacileyo okucacileyo (i-37% ilula kunamaphepha aqhelekileyo e-resin, kunye nokuchasana kwempembelelo kuphezulu njengamaphepha aqhelekileyo e-resin) 12 amaxesha eresin!)
