Okokuqala, masiqonde ukuthi i-lens eqhubekayo, futhi ukuhlukaniswa kwamalensi kungachazwa njengento yonke.Uma ihlukaniswa kusukela endaweni okugxilwe kuyo, amalensi angahlukaniswa abe amalensi okugxila okukodwa, amalensi e-bifocal, namalensi amaningi.Amalensi e-multifocal aqhubekayo, abuye aziwe ngokuthi amalensi aqhubekayo, anezindawo eziningi zokugxila kulens.
Amalensi aqhubekayo awumkhiqizo wokuhlolwa kwezikhathi.Njengoba iminyaka ikhula, ikhono leso lokuhlala liyancipha kancane kancane, okubangela ukuthi isiguli sibe nobunzima bokubona eduze, ukuze emsebenzini obona eduze, i-myopic kufanele ingeze i-convex lens ngaphezu kokulungiswa kwayo kwe-static babe nombono ocacile.yokubona eduze.Esikhathini esidlule, abantu abaningi asebekhulile babesebenzisa ama-bifocal lens ukuze baxazulule inkinga yokubona kude naseduze ngesikhathi esisodwa, kodwa ngenxa yokubukeka kwabo okungekuhle kanye nokuthandwa kwama-multifocals aqhubekayo, amalensi e-bifocal aqedwa ngokuyisisekelo;amalensi ama-multifocal ayingqophamlando emlandweni wokuthuthukiswa kwamalensi., futhi izophinde ibe isiqondiso esiyinhloko sokucwaninga nokuthuthukiswa kososayensi kanye nokuthandwa kwezimakethe esikhathini esizayo.Ilensi eqhubekayo iwukuthola ibanga elikude, eliseduze, nelimaphakathi kwilensi eyodwa, ukugwema inkinga yokushintsha izibuko njalo.Kuningi esikuzwile mayelana nokuqeqeshwa okuqhubekayo, kodwa akuwona umkhiqizo omusha, kodwa abantu abaningi asebekhulile abasazi ukuthi benzeni.Uma kukhona umkhiqizo onjalo, sizothatha isinyathelo sokubuza.Yiqiniso, singase futhi sithathe isinyathelo sokuyethula futhi sibazise ukuthi ngaphezu kwezibuko zokufunda, kunezinketho ezinjalo ezengeziwe ezilula.
Yiziphi izinzuzo zamafilimu athuthukayo?
1. Ukubonakala kwelensi kufana nelensi yombono owodwa, futhi umugqa ohlukanisayo wokushintsha kwamandla awukwazi ukubonakala.Akukona nje kuphela ukuthi yinhle ngokubukeka, kodwa okubaluleke kakhulu, ivikela ubumfihlo beminyaka yomuntu oyigqokile, futhi asikho isidingo sokukhathazeka ngokudalula imfihlo yeminyaka ngenxa yokugqoka izibuko.
2. Njengoba ukuguqulwa kwamandla e-lens kuhamba kancane, ngeke kube khona njengokugxuma.Kukhululekile ukugqoka futhi kulula ukuzivumelanisa, ngakho kulula ukwamukelwa.
3. Ngenxa yokuthi idigri ihamba kancane, ukushintshwa komphumela wokulungisa nakho kuyanda kancane kancane ngokuya ngokufinyezwa kwebanga elibonakalayo, akukho ukushintshashintsha ekulungiseni, futhi akulula ukubangela ukukhathala okubukwayo.
4. Ukubona okucacile kutholakala kuwo wonke amabanga endaweni yokubuka.Ipheya yezibuko yenelisa ukusetshenziswa kwebanga, amabanga aseduze namaphakathi ngesikhathi esisodwa.
Ingabe kufanelekile ukuba asebekhulile bagqoke?
Kuyafaneleka.Lapho ifilimu eqhubekayo idalwa, yayisetshenziselwa asebekhulile, futhi kamuva yathuthukiswa kubantu abaneminyaka ephakathi nentsha, kodwa lapha ngikhumbuza wonke umuntu ukuthi ifilimu eqhubekayo ayifanele wonke umuntu.Iya kudokotela wamehlo ojwayelekile ngaphambi kokuthola izibuko., bese ukhetha ilensi ngemva kwe-optometry enengqondo.
