Ukuhlelwa kwezinto ezintathu
Iilensi zeglasi
Kwiintsuku zokuqala, izinto eziphambili zeelensi yayiyiglasi yeglasi.Oku kungenxa yokuba ngokuqwalasela ukuhanjiswa okuphezulu kunye nokucaca kweelensi zeglasi, itekhnoloji ikhulile kwaye ilula.Nangona kunjalo, ingxaki enkulu yeelensi zeglasi kukhuseleko, ukuchasana kwayo neempembelelo kubi, kulula kakhulu ukuphuka, kwaye ngenxa yempahla yayo enzima, ayikhululekile ukuyinxiba, ngoko ayifane isetyenziswe kwiimarike ngoku.
Iilensi ze-resin
Ilensi yeresin luhlobo lwelensi yokubona eyenziwe ngentlaka njengemathiriyeli ekrwada, icutshungulwe, idityaniswe kwaye ipolishwe yinkqubo yekhemikhali echanekileyo.Okwangoku, i-resin lens yeyona nto isetyenziswa kakhulu.Ubunzima be-resin lens bukhaphukhaphu kunobo be-lens yeglasi ye-optical, kwaye ukuchasana kwempembelelo kunamandla kuneglasi, kwaye akukho lula ukuphuka, ngoko kukhuselekile ukusebenzisa.Ngokwexabiso, iilensi zeresin nazo zifikeleleka ngakumbi.Kodwa ukuxhathisa ukunxiba kwe-resin lens kubi, isantya se-oxidation sikhawuleza, umphezulu we-lens kulula ukukrwela.
Iilensi zePC
I-lens ye-PC luhlobo lwelensi eyenziwe nge-polycarbonate (i-thermoplastic material) emva kokufudumeza kunye nokubunjwa.Olu hlobo lwemathiriyeli yaphuhliswa kwiprogram yesithuba, ngoko ikwabizwa ngokuba yifilimu yasemkhathini okanye ifilimu yasemajukujukwini.I-PC resin luhlobo lwemathiriyeli ye-thermoplastic esebenza kakuhle, ngoko ifaneleke ngakumbi ukwenza iiglasi zamehlo.Ukuchasana kwempembelelo yelensi yePC kuhle kakhulu, phantse akwaphuki, ukhuseleko oluphezulu kakhulu.Ngokumalunga nobunzima, kukhanya ngakumbi kune-resin lens.Kodwa i-lens yePC iya kuba nobunzima ekusebenzeni, ngoko ke ixabiso liphezulu.
Ukushwankathela:
| Izinto eziphathekayo | Inzuzo | Ukunqongophala |
| Ilensi yeglasi | Ukuhanjiswa okuphezulu kunye nesalathiso se-refractive, ukumelana nokunxiba | Inzima kwaye kulula ukuphuka |
| I-resin lens | Ukukhanya, akuphuki lula, ixabiso eliphantsi | Kulula ukukrwempa |
| Ilensi yePC | Ukukhanya kwaye akukho lula ukwaphuka | Kulula ukukrwempa kunye nexabiso eliphezulu |
Izinto ezifanelekileyo kubantu abadala
I-presbyopia esele ikhulile yacebisa ukuba kukhethwe iilensi zeglasi okanye iilensi zeresin.Ngokuqhelekileyo, i-presbyopia yifilimu ye-hyperopia ephantsi, engadingi ubunzima obuphezulu be-lens, kwaye i-coefficient ye-motion yabantu abadala ayikho phezulu.Ifilimu yeglasi okanye i-super-hard resin iyakwazi ukumelana nemikrwelo, kwaye ukusebenza kwamehlo kunokomelela.
Izinto ezilungele abantu abadala
Iilensi ze-resin zifanelekile kubantu abancinci nabaphakathi.Ukukhethwa kwe-resin lens kubanzi, ngokuhambelana ne-refractive index distinction, ulwahlulo olusebenzayo, ukuhlukana kwe-refractive focus, kunokuhlangabezana neemfuno ezahlukeneyo zabantu abahlukeneyo.
Izixhobo ezifanelekileyo zabantwana kunye nolutsha
Abazali bacetyiswa ukuba bakhethe iilensi ezenziwe ngeepilisi zePC okanye izinto ze-Trivex.Xa kuthelekiswa nezinye iilensi, ezi lens azikho nje ukukhanya kubunzima, kodwa zikwanokumelana nempembelelo engcono kunye nokhuseleko oluphezulu.Ayisiyiyo loo nto kuphela, iitafile zePC kunye neelensi ze-Trivex zikwakhusela amehlo akho kwimitha ye-UV.
Olu hlobo lwelensi lunokuqina olomeleleyo kwaye akulula ukuluqhawula, ngoko lubizwa ngokuba ilensi yokhuseleko.Kwi-2 grams nje nge-cubic centimeter nganye, yeyona nto ilula ekhoyo kwiilensi.Iiglasi zabantwana azifanelekanga iilensi zeglasi, kuba abantwana bayasebenza, kwaye iilensi zeglasi zibuthathaka, ukuba ziphukile, zinokulimaza amehlo.
Ubhale okokugqibela
Iilensi zezinto ezahlukeneyo zineempawu ezahlukeneyo zemveliso.Icwecwe leglasi linzima kwaye linokhuseleko oluphantsi, kodwa liyakwazi ukumelana nokukrweleka kwaye linomjikelo wokusebenzisa ixesha elide.Ilungele abantu abadala abanomsebenzi omncinci kunye ne-presbyopia ephantsi.I-resin lens inemisebenzi emininzi eyahlukeneyo, ilungele abantu abatsha kwiindidi ezahlukeneyo zokufunda kunye neemfuno zomsebenzi;Ukhuseleko lwelensi yabantwana, iimfuno zokuphatheka ziphezulu, iilensi zePC lukhetho olungcono.
