Okokuqala, yini lens eqhubekayo multifocal lens?
Ukugxila okungaphezulu kwe-1, kancane kancane amalensi akwilensi efanayo kuphela phakathi kokukhanya futhi okucishe kwaphela, nge-dioptre indlela yokushintsha kancane kancane, kusuka kancane kancane asondele ekusetshenzisweni ngokude, ngakho-ke kuphelelwe yi-organic ndawonye, ngakho-ke I-Lens ngasikhathi sinye bheka ibanga, ibanga eliphakathi bese uvala ukugcwala okuhlukile okuhlukile.
Ama-lens athuthukayo anezindawo ezintathu ezisebenzayo
Indawo yokuqala yokusebenza yindawo eyihlane etholakala phezulu kwelensi. Ibanga le-PACK liyinombolo yama-degree adingekayo ukuze abone kude, esetshenziselwa ukubona izinto ezikude.
Indawo yesibili yokusebenza yindawo yokusondela etholakala emaphethelweni aphansi amalensi. Ukusondela yinombolo yamadigri adingekayo ukubona izinto eziseduze.
Indawo yesithathu yindawo ephakathi exhumanisa zombili. Ibizwa ngokuthi yindawo ye-Gradient, eshintsha kancane kancane izinga lokubheka kude nezinga eliseduze, ukuze ukwazi ukulisebenzisa ukuze ubone izinto ebanga eliphakathi. Ngokubukeka, amalensi we-multifocal actionstestiocal aqokwa ama-lens ajwayelekile.
Ezimbili, hlobo luni lwelensi eguqukayo ehlukahlukene?
Eminyakeni yamuva nje, ilensi ye-sultifocal eguqukayo ibilokhu ithuthuka futhi yaziswa ngokushesha eChina. Njengamanje, ngokuya ngemodi yokusebenzisa iso kanye nezimpawu zomzimba zabantu beminyaka ehlukene, ucwaningo oluhambisanayo ngama-lens amaningi agxilwe ezigabeni ezintathu:
1. I-Sheegecech Myopia elawula ilensi. Kusetshenziselwa ukunciphisa ukukhathala okubonakalayo nokulawula ukuthuthukiswa kwe-myopia.
2. I-anti-ikati lens kubantu abadala. Isetshenziselwa abantu abaningi abasebenza ibanga eliseduze ukuze banciphise ukukhathala okubonakalayo okubangelwa umsebenzi.
3. Ama-lens athuthukile kubantu abaneminyaka ephakathi nabantu asebekhulile. Ingilazi ezimbili zabantu abaneminyaka ephakathi nendawo nabantu asebekhulile bangabona kalula kude futhi eduze, ukuze amehlo akho athole umuzwa wobusha.
Emithathu, yini umsebenzi welensi ye-multifocal eqhubekayo?
.
Qaphela: Ngoba iningi leziguli ezine-Myopia linokusebenzelana kwezimo zangaphandle kunokuba kube lula ukusebenzelana nezimo ezivelele, inani labantu abalungele ukugqoka izingilazi ze-multifopal zokulawula i-myopia kanye nentsha kuphela yezingane nentsha enezingane.
(2) Othisha, odokotela, ibanga elisondele kakhulu kanye nabantu abaningi kakhulu besebenzisa amakhompyutha, ukuze banciphise ukukhathala okubonakalayo okulethwe ngumsebenzi.
Kwabantu abaneminyaka ephakathi nabantu asebekhulile abanezingilazi ezimbili ukuze babone kalula okude. I-Progressivective multifocal lens yakhelwe ukuhlinzeka ngendlela yemvelo, elula nentofontofo yeziguli ze-Presbyopia ukuze ilungiswe. Ukugqoka ilensi eqhubekayo kufana nokusebenzisa ikhamera yevidiyo. Ingilazi ezimbili zingabona izinto ezikude, eziseduze neziphakathi nebanga eliphakathi. Ngakho-ke, sichaza ama-lens athuthukayo njenge- "lens asondeza", futhi afake izibuko ezilingana nokukhokha okuningi ezingilazini.
Okwesine, yini okufanele nginake lapho ngigqoka amalensi we-multifocal lens?
(1) Lapho ukhetha uhlaka lwesibuko, usayizi wohlaka luqinile. Kuyadingeka ukukhetha ububanzi obufanele nokuphakama ngokuya ngebanga le-Pupil.
(2) Ngemuva kokugqoka izibuko, lapho ubheka izinto ezinhlangothini zombili, ungathola ukuthi ukucaciswa kuncishisiwe futhi into ichithiwe, okujwayelekile kakhulu. Ngalesi sikhathi, udinga ukuguqula ikhanda lakho kancane bese uzama ukubona kusuka enkabeni yelensi, futhi ukungaphatheki kahle kuzonyamalala.
(3) Lapho kwehla ezansi, izingilazi kufanele zibe ngaphansi ngangokunokwenzeka kusuka phezulu ukuze zibone ngaphandle kwendawo.
