Amalensi aqhubekayo, abhekisela kumalensi agxile kakhulu, agqokwa kakhulu eYurophu nase-United States, kodwa aduma eShayina kuphela eminyakeni eyi-10 edlule.Ake sibheke isithombe sezibuko ze-multifocal eziqhubekayo.
Namuhla, abantu abaningi baye bagqoka izibuko ze-multifocal eziqhubekayo, futhi izibuko eziqhubekayo seziyinto evamile.
Nokho, akuwona wonke umuntu ongathola ekahle izibuko okuqhubekayo.Abantu abaningi ngesikhathi sokuqala, abafuni ukufanisa, isizathu akuyona into engaphezu kokugqoka ukungakhululeki, ukuchitha imali eningi, kodwa abazange bafinyelele lokho ababekulindele.
Idizayini yamalensi agxile kakhulu angahlukaniswa ngokwenqubekelaphambili yangaphakathi kanye nenqubekela phambili yangaphandle.Ubuchwepheshe nolwazi lokufakwa kwamalensi okuqhubekayo kuzophinde kuthinte umuzwa wokugqoka.Ngakho-ke, ukuqonda ukwakheka kwamalensi kungakusiza ukuthi uthole izibuko ezikhululeke kakhudlwana.
Ngaphakathi imiqondo eqhubekayo nangaphandle eqhubekayo
Ilensi yangaphandle eqhubekayo:Ukwakheka kancane kancane konke kungaphandle kwelensi, futhi incwadi kadokotela icutshungulwa endaweni engaphakathi yelensi.
Idizayini eqhubekayo yocezu oluqhubekayo lwangaphandle olulungisiwe lunezinkinga ezisobala, ezingeke zenziwe ngokwezifiso ngokwezidingo zomuntu ngamunye zeso, futhi ukuklama nokucubungula kungokwesiko.
Ilensi eqhubekayo yangaphakathi:Indawo ehamba kancane itholakala endaweni engaphakathi, futhi isici esiqondile sitholakala endaweni engaphakathi.
Njengoba indawo engemuva ingaklanywa futhi icutshungulwe ngendlela eguquguqukayo, ukukhanya kancane kancane kanye nokukhanya okunikezwe udokotela kungathuthukiswa ngokuya ngencwadi yomuntu ngamunye, amapharamitha okugqoka kanye nemikhuba yokubuka yomuntu siqu, ukuze kuthuthukiswe isipiliyoni sokubuka salowo ogqokile.
Ngaphakathi umehluko oqhubekayo oqhubekayo nangaphandle
Ububanzi benkambu ebonakalayo: Inkambu yokubuka eqhubekayo yangaphakathi ibanzi
Ngenxa yokuthi ingaphezulu eliqhubekayo lendawo engaphakathi iseduze nenhlamvu yeso, ukugqoka le lensi kungakhuphula i-engeli yokubuka yomuntu oyigqokile, kuthuthukise ububanzi bendawo yokubuka emaphakathi kanye nokusetshenziswa okubonakalayo kwendawo ezungezile, futhi umphumela wokuthwebula ubonakala ungokoqobo futhi ucacile. .Uma kuqhathaniswa nobuso obuqhubekayo bendawo yangaphandle, inkambu yokubuka ikhula cishe ngo-35%.
Eduze kokuqina kokunethezeka: ngaphakathi kugqoka kancane kancane
I-inner progressive ithatha ubuchwepheshe obuyingqayizivele, okwenza i-lens deformation ibe mncane kunendawo yangaphandle iqhubekela phambili, futhi indawo yokuphambuka iseduze nezinhlangothi zombili ze-lens, futhi indawo yokuguqulwa kokuphazanyiswa okubonakalayo incane, ngakho-ke induduzo yokugqoka ithuthukiswa kakhulu, futhi ukuzivumelanisa nezimo kuyashesha.
Izidingo ze-backspin: Ngayinye inezinzuzo zayo
Kumakhasimende anekhono elihle lokubuyisela emuva amehlo, ukwamukelwa kancane kancane kwevelu ye-ADD ephansi noma isiteshi eside kungcono kakhulu.Kumakhasimende anekhono lokubuyisela emuva elimpofu, inani eliphezulu le-ADD noma ukusetshenziswa okuqhubekayo kwesiteshi esifushane sokusebenza kahle kwangaphandle okuqhubekayo.
Izidingo ezenziwe ngokwezifiso: Okuqhubekayo kwangaphakathi kungaba idizayini yomuntu siqu
Amapharamitha welensi eqhubekayo yangaphakathi angenziwa ngokugcwele ngokuhambisana nezidingo zedigri yamehlo kanye nomkhuba wokusebenzisa, okusho ukuthi izibuko ezenzelwe amakhasimende zihambisana kakhulu nezidingo zangempela zokugqoka zamakhasimende.
Ithrendi enkulu eshisayo: kancane kancane yangaphakathi ihlangabezana nesidingo
Kulezi zinsuku, ngenxa yokuthuthukiswa kwezinga lempilo yabantu, isimo sokukhathala kwamehlo sibalulekile, futhi i-presbyopia ikhombisa ukuthambekela kwentsha.Ngakho-ke, ngaphansi kwesimo sokuthi amandla e-cyclotral emisipha yeso anelisekile, ukuhamba kancane kwangaphakathi kuyisinqumo esibalulekile ukuhlangabezana nezidingo zamakhasimende zombono obanzi nokuthuthukisa ukwaneliseka.
Isizathu sokungakhululeki ekugqokeni ucezu oluqhubekayo
Ekugqokeni kwansuku zonke, kukhona nezinye izimbangela zokungakhululeki kokugqoka kwelensi elandelayo
1. Ibala lelensi
Izibuko ekusetshenzisweni kwansuku zonke ukunakwa okuncane kuzongcoliswa ngamabala othuli, kuthinte umbono;Amalensi aklwetshiwe angaphinde aphazamise ukudlula kokukhanya, okuholela ekuboneni kahle nokungakhululeki.
Ukusikisela: Izibuko kufanele zihlanzwe ngesikhathi sokusetshenziswa.Geza insila yelensi ngamanzi, bese uyisula ngobumnene ngendwangu yokuhlanza ingilazi yamehlo ehlanzekile nethambile ukuze ugweme imihuzuko.Uma ilensi inemihuzuko eminingi, kufanele ishintshwe ngesikhathi.
2. Ukuguqulwa kwesibuko sohlaka
Izingilazi ezisetshenziswe isikhathi eside nakanjani zizocindezelwa, zidonswe, zihlanekezelwe kanye nokuguqulwa kohlaka.Uma isikhungo sokubonwa kwelensi singakwazi ukuya ngqo kumfundi, ukuchezuka kungabangela ukulimala kweso futhi kunciphise ukunethezeka kokubuka.
Ukusikisela: Izibuko akufanele zifakwe ephaketheni noma esikhwameni ngokuthanda kwakho, kodwa kufanele zigcinwe ebhokisini lesibuko futhi zigcinwe kahle.Uma kutholakala ukuthi ukuhlanekezela kwefreyimu yesibuko akukwazi "ukwenza", kuyadingeka ukucela ochwepheshe ukuba balungise futhi balondoloze ngesikhathi.
3. Ukufanisa akufanelekile
Ngaphezu kwezinga le-myopia ne-presbyopia, ukusetshenziswa kwansuku zonke ngemva kokugqoka kufanele kucatshangelwe.Idigri yobungcweti yomhloli kanye nekhwalithi yelensi kuyadingeka ukuthi ibe phezulu kakhulu.Ukufakwa okungafanele komhloli kulula ukubangela ukungakhululeki.
Ukusikisela: Qiniseka ukuthi ukhetha isibhedlela samehlo esivamile, esiqeqeshiwe noma udokotela wamehlo, ngodokotela wamehlo ochwepheshe.
