Amalensi e-bifocal angabonakali amalensi ezingubo zamehlo obuchwepheshe obuphezulu angalungisa ngesikhathi esisodwa kokubili i-hyperopia ne-myopia. Ukuklama kwalolu hlobo lwe-lens akugcini nje ukucabangela izinkinga izibuko ezijwayelekile ezingalungisa, kodwa futhi zicabangela izinkinga ezibukwayo ezikhona emaqenjini akhethekile. Kulesi sihloko, sizonikeza isingeniso esinemininingwane yemisebenzi kanye nezinzuzo zamalensi e-bifocal angaphatheki.
Izici: Kunamaphuzu amabili okugxilwe kuwo kupheya elilodwa lamalensi, okungukuthi, kulensi eyodwa evamile
Gqoka ilensi encane enokukhanya okuhlukile kulensi:
Isetshenziswa ngokushintshana ezigulini ezine-presbyopia ukubona kude nokuvala:
Ngenhla ibanga lokubuka (kwesinye isikhathi ukukhanya okuyisicaba), futhi ngezansi yibanga lokubuka
Isikhathi sokufunda:
Idigri ekude ibizwa nge-up light, futhi idigri eseduze ibizwa ngokuthi ukukhanya okuphansi
Umehluko ophansi wokukhanya yi-ADD (ukukhanya kwangaphandle);
Ihlukaniswe ngomugqa wokukhanya okukabili, ukukhanya okukabili okuphezulu okuyisicaba, kanye nesiyingi ngokuya ngokuma kwesiqephu esincane
Ukukhanya okuphindwe kabili okuphezulu, njll.
Izinzuzo: Lokhu kuqeda isidingo sokuthi iziguli ezine-presbyopia zishintshe izibuko zazo lapho zibuka eduze nakude.
Ukungalungi: Kunento yokugxuma lapho ushintsha phakathi kokubheka kude nokubheka eduze;
Kunomehluko omkhulu ekubukekeni kwamalensi avamile.
Ngokwesimo sengxenye yokukhanya ephansi yelensi ye-bifocal, ingahlukaniswa ibe:I-Flat-Top,Round Phezulu kanyeAkubonakali.
Uma kuqhathaniswa ne-Flat-Top kanye ne-Round-Top, Ilensi Engabonakali inenzuzo yokungakwazi ukuhlukanisa ngokucacile umngcele phakathi kwe-myopia ne-presbyopia kusukela ekubukeni kwayo, futhi ifana kakhulu namalensi amalensi awodwa avamile. Uma ubheka izinto, awukho umuzwa osobala wokuvinjwa, okwenza ukugqoka kube ntofontofo.
Lena ilensi yethu engabonakali yesithombe esinesithombe esine-semi-finished, engase futhi ibe nokukhanya okuluhlaza okwesibhakabhaka kanye nemiphumela eshintsha umbala.
Awukho umngcele ocacile, akunjalo?
Ngemva kokukhanyiswa ukukhanya okushintsha umbala, kubonakala kumpunga.
Uma unentshisekelo kulo mkhiqizo, sicela usithinte.Khetha amalensi angabonakali ukuze ulethe isipiliyoni sokunethezeka esingalindelekile!
