Izici zekhwalithi yangaphakathi yamalensi e-resin:
1. Ikhwalithi yezinto eziyisisekelo
Ikhwalithi ye-substrate inquma ukuqina kwe-lens nokuthembeka kwe-coating.I-substrate enhle ecacile futhi ekhanyayo, isikhathi eside sokusebenzisa futhi akulula ukuphuzi;Futhi amanye ama-lens asebenzisa isikhathi asiphuzi isikhathi eside, ngisho nokuvala.Ilensi enhle ngaphandle kokuklwebheka, ukuklwebheka, izinwele, i-pitting, i-lens oblique ekubonweni kokukhanya, isiphetho esiphezulu.Awekho amabala, amatshe, imivimbo, amabhamuza kanye nemifantu ngaphakathi kwelensi, futhi ukukhanya kuyakhanya.
2. Ibanga le-lens
Amalensi akhiqizwe ngobuningi ahlukaniswa abe amamaki ahlukene ngenxa yomehluko wekhwalithi yangaphakathi, futhi amanani emikhiqizo esezingeni eliphezulu nephansi ahluka kakhulu.
3. Inkomba ye-refraction
Uma iphezulu inkomba ye-refractive, i-lens iba mncane, futhi intengo iphezulu.
4. Ukwelashwa kwe-coating kanye ne-anti-ultraviolet
Ishidi le-resin lingenziwa lukhuni (ukumelana nokunwebeka), i-anti-reflection, i-anti-static, i-dustproof, i-coating ye-resin engangeni manzi izendlalelo eziningi, ukucutshungulwa okuhlukile kunendima ehlukile, uma kunciphisa inqubo yokucubungula, ikhwalithi yelensi. kuzoncishiswa kakhulu.Ngokufanayo, kuyingozi kakhulu emehlweni uma amalensi angayivimbi imisebe ye-ultraviolet egqokwa njengamalensi avimbela imisebe ye-ultraviolet.Iso lomuntu limunca kakhulu ukukhanya kwe-ultraviolet ukuze kubangele kalula izifo ezihlukahlukene zamehlo ezifana ne-photoinduced keratitis, cataract kanye ne-macular degeneration.
5. Uhlobo lwamalensi
Ukwehluka kwemikhiqizo kuholela ekuhlukeni kwekhwalithi namanani.Ikhwalithi yelensi ibonakala ngokuqondile kumkhiqizo welensi.Izinga lamalensi adumile lihle futhi lizinzile.Njengoba ilensi icutshungulwa ngemuva, kungakhathaliseki ukuthi iyiqiniso noma cha, abathengi abakwazi ukulandelela nokukhomba, ngokuyinhloko bathembele kubuqotho bomsebenzisi.Indlela yokwethembeka iwukuthi lapho amakhasimende efanisa izibuko, umnikazi wesitolo kufanele abonise uhlobo, uhlobo, inkomba ye-refractive kanye nesimo sokumbozwa kwelensi kudokhumenti, kanye nekhono lokuvimbela ukukhanya kwe-ultraviolet kufanele futhi achazelwe ikhasimende.Uma i-lens ye-resin ibhaliwe ngokujwayelekile, ukungafani kukhulu kakhulu, ikhwalithi yangaphakathi ye-lens ayaziwa.Ibanga le-ABC lisetshenziselwa kuphela ukuhlukanisa lapho umenzi ekhiqiza, empeleni, izinga likazwelonke aliwudingi lowo mehluko.Kunjalo, kungakhathaliseki ukuthi yiliphi ibanga le-ABC lens elifanelekayo.
6. Ukungafihli nokufana kokubona kwelensi
Bamba ilensi ibanga elingamasentimitha angama-30 ukusuka kweso bese ubheka indawo ekude ngelensi.Uma indawo icacile futhi ingenayo i-deformation, futhi kungekho scene gxuma lapho uhambisa ilensi kancane, ukukhanya nokufana kokubona kwelensi kuhle.
7. Isiqondiso se-axial se-astigmatism lens
Ephepheni elingenalutho ukuze udwebe imfoloko yesiphambano se-perpendicular, faka i-lens kumdwebo wesicabucabu zungeza ngaphezu kwamasentimitha angama-30, ilensi ebonakalayo inyakazisa isiphambano ngemfoloko yesiphambano, ilensi ngaphakathi futhi lapho ixhunywe kwihluzo eziphambanweni, ihluzo zaziwela, lapho ikholomu i-axis yelensi kanye nomugqa oqondile, khona-ke amalensi ayehamba ngokuphindaphindiwe emgqeni oqondile;Qaphela ukuthi yimuphi umugqa ohluka kakhulu emugqeni ongaphandle kwelensi lapho uhamba, futhi lo mugqa uyisiqondiso se-eksisi ye-scatterlight.Hambisa ilensi ukuze umugqa wangaphakathi nangaphandle ukhuphuke, nansi i-eksisi yokuhlukana.Ngemva kokumaka kwilensi, kala i-axial ne-Angle evundlile phakathi nendawo yelensi nge-protractor, okuyi-axial degree.
8. Ukufuduka kwesikhungo se-Optical
Dweba isiphambano esikhulu ephepheni elimhlophe emgqeni omncane, ocacile, oqondile.Bamba i-lens phakathi kweso nesiphambano, bheka ukuma kwesiphambano esibukweni ngeso elilodwa, uma ngaphakathi nangaphandle kwesibuko kungekho emgqeni, ungakwazi ukuhambisa i-lens, ukuze ngaphakathi kwe-lens futhi ngaphandle kwesibuko umugqa wesiphambano.Sebenzisa ibhulashi noma ipeni lomthombo ukuze ubeke iphuzu elincane enkabeni yesiphambano se-lens, okuyisikhungo se-optical.Ngemva kokukhomba izikhungo zokubona zawo womabili amalensi, bheka futhi uqhathanise ukuthi izikhungo ze-optical zamazwe amabili ziyafana yini, futhi ulinganise ibanga phakathi kwezikhungo ezimbili ngerula elincane ukuze ubone ukuthi ibanga phakathi kwalezi zikhungo ezimbili liyahambisana yini nebanga elinqunyiwe kumfundi. .Uma isiphambano ku-lens sigobile, sibonisa ukuthi kukhona ukucindezeleka kwangaphakathi noma ukuminyana optical ongalingani welensi.
9. Gqoka ukunethezeka
Gqoka ngaphandle kokuzizwa, isiyezi nokuvuvukala kwamehlo, izinto zokubuka azifiphaziwe, azikhubazekile.Lapho uthenga, bamba izibuko ngesandla bese ubheka izinto ezikude ngeso elilodwa nge-lens.Nyakazisa ilensi phezulu naphansi.Inkohliso yokuhamba kwezinto ezikude akufanele yenzeke.
10. Ukuzivikela
Amalensi ekhwalithi ephezulu angavimba i-UV A ne-UV B ngo-100%, anikeze isivikelo se-uv esisebenza kahle kakhulu kumuntu ogqokile.
