Lens resin waa nooc ka mid ah muraayadaha indhaha ee laga sameeyay xabagta sida walxo ceeriin ah, kaas oo la farsameeyo, la farsameeyo oo lagu sifeeyo hannaan kiimiko oo sax ah. Isla mar ahaantaana, resin waxa loo qaybin karaa resin dabiici ah iyo resin synthetic.
Faa'iidooyinka muraayadaha resin: iska caabin xoog leh, ma fududa in la jebiyo, gudbinta iftiinka wanaagsan, index refractive sare, miisaanka fudud iyo kharash yar.
Muraayada kombuyuutarku waa nooc ka mid ah muraayadaha lagu sameeyo kuleylinta polykarbonate (walax heerkulbeeg ah). Qalabkan waxaa laga soo saaray sahaminta hawada sare, sidaas darteed waxaa sidoo kale loo yaqaan filimka hawada sare ama filin bannaan. Maadaama uu kombuyuutarku yahay walxo heerkulbeeg leh oo leh sifooyin aad u wanaagsan, waxay si gaar ah ugu habboon tahay samaynta muraayadaha indhaha.
Faa'iidooyinka muraayadaha kombuyuutarrada: 100% fallaadhaha ultraviolet, wax huruud ah ma laha 3-5 sano gudahood, iska caabin weyn oo saameyn leh, index refractive sare, cufnaanta gaarka ah ee iftiinka (37% ka fudud xaashida caaga ah ee caadiga ah, caabbinta saameyntuna waxay u badan tahay sida xaashida resin caadiga ah) 12 jeer xabagta!)
