Enye into ebalulekileyo ekufuneka uyiqwalasele xa ukhetha iilensi zezinto ezibonakalayo.
Iplastiki kunye ne-polycarbonate zii-lens eziqhelekileyo ezisetyenziswayo kwamehlo.
Iplastiki iphosakele kwaye iqine kodwa inkulu.
I-Polycarbonate inomthi omncinci kwaye ibonelela ngokukhuselwa kwe-UV kodwa ukukrala ngokulula kwaye kuyabiza kakhulu kuneplastiki.
Izinto nganye nganye ineempawu ezizodwa ezenza zilungele ngakumbi kumaqela athile, iimfuno kunye neendlela zokuphila. Xa ukhetha izixhobo ze-lens, kubalulekile ukuba uqaphele:
● Ubunzima
● Ukunganyangeki kwempembelelo
● Ukungaxhathisi
● Ubunzima
● I-Ultraviolet (UV) ukhuseleko
● Ixabiso
Amagqabantshintshi ngeelensi zeplastiki
Iilensi zeplastiki zikwabizwa ngokuba yiCR-39. Ezi zixhobo zisetyenziswe ngokubanzi kwamehlo eliso ukusukela ngo-1970 kwaye ziselukhetho oludumileyo phakathi kwabantu abanxiba iiglasi zeDristi kagqirha ngenxa yeyayoIxabiso eliphantsi kunye nokuqina. I-scratch-Ukudibana okunganyangekiyo, i-tint kunye ne-ultraviolet (UV) Ukudibana okukhuselayo kunokutongelwa ngokulula kule lenses.
● UkukhanyaXa kuthelekiswa neglasi yesithsaba, iplastiki iphosakele. Iiglasi ezinelebhu zeplastiki zikhululekile ukuba zinxibe ixesha elide.
● Ukucaca okuqinisekileyo-Iilensi zeplastiki zibonelela ngokucacileyo. Ababangeli ukugqwetha kakhulu.
● Uhlala phantsi -Iilensi zeplastiki zinokwenzeka ukuba ziphule okanye zikhuphe kuneglasi. Oku kubangela ukuba babe lukhetho olufanelekileyo kubantu abakhutheleyo, nangona bengazange bangqubana-bungqina njenge-polycarbonate.
● Kubiza kakhulu -Iilensi zeplastiki zihlala zixabisa kancinci kancinci kune-polycarbonate.
● Ukhuseleko lwe-UV lwe-UV -Iplastiki ibonelela ngokhuseleko lwenxalenye kuphela kwi-UV eyenzakalisayo. I-UV yokudibana kufuneka yongezwe ukhuselo lwe-100% ukuba uceba ukunxiba iiglasi ngaphandle.
Amagqabantshintshi ngeelensi zePolycarbondate Lenses
I-Polycarbonate luhlobo lweplastiki yefuthe elixhaphakileyo kakhulu esetyenziswe esweni. Iilensi zokuqala ze-polycarboate ze-polycarbonate zaziswa nge-1980s, kwaye zakhawuleza zaphakama.
Ezi zinto ze-lens zinamaxesha alishumi ngaphezulu kwefuthe elingaphantsi kuneplastiki. Ngesi sizathu, idla ngokunconywa abantwana kunye nabantu abadala abasebenzayo.
●Hlalani -I-Polycarbonate yenye yezona zinto zinamandla kwaye zikhuselekile ezisetyenziswayo namhlanje kwiiglasi. Ihlala icetyiswa kubantwana abancinci, abantu abadala abasebenzayo, kwaye abantu abafuna iliso lezinto zotyalo-mali.
●Mncinci kwaye ulula -I-polycarbonate lenseds ikude ibe ngama-25 epesenti kancinci kuneplastiki yemveli.
●Iyonke i-UV yoKhuseleko lwe-UV -I-polycarbonate blocks i-rays, ke akukho sidingo songeza i-UV ikhathaza iiglasi zakho. Ezi lens zizinto ezikhethiweyo kubantu abachitha ixesha elininzi ngaphandle.
●I-scratch-Ukucetywa ukunyangwa kuyacetyiswa -Nangona i-polycarbonate iqine, impahla isaqhubeka nokukhulisa. Ukudibana okunganyangekiyo okunyangekayo kuyacetyiswa ukunceda ezi zenzo zihlala ixesha elide.
●I-Anti-Retiverance Coating iyacetyiswa -Abanye abantu abanomyalelo okuphezulu babona ukubonakaliswa komphezulu kunye nokuphelisa imibala xa kunxibe iilensi zePolycarbondate Lenses. Ukudibana okubonakalayo kuyacetyiswa ukunciphisa le mpembelelo.
●Umbono ogqwethiweyo -I-Polycarbonate inokubangela umbono othile ogqwethekileyo kwabo banemiyalelo eyomeleleyo.
●Ebiza kakhulu -I-polycarbonate lenseds ihlala ixabisa ngaphezulu kweelensi zeplastiki.
