Uchungechunge oluqhubekayo endaweni ekhululekile
Ilensi eqhubekayo endaweni yefomu yamahhala inomkhakha wokubuka omkhulu ngo-30% kunelensi evamile eqhubekayo.
Ilensi eqhubekayo yangaphakathi idlula umklamo oqhubekayo ovamile.
Kwabagqoki abahlukene, ukubalwa kokulungiswa kokukhanya kwelensi kwenziwa ngokuya ngokukhanya okugunyazwe udokotela, futhi umphumela wangempela wokugqoka welensi eqhubekayo ulingiswa kusengaphambili, bese inkumbulo yohlelo y isetshenziselwe ukucutshungulwa okunemba okuphezulu ukuze kuncishiswe okubonakalayo. inkinga yenkambu yokuhlanekezela.Phansi, hlinzeka ngekhwalithi yokubonwayo enhle kakhulu.Njalo ucezu lwelensi eqhubekayo eyakheke kahle inomkhakha wokubona onethezekile futhi obanzi wemvelo endaweni ekude, emaphakathi naseduze, futhi kulula ukuzivumelanisa nayo, iletha okuhlangenwe nakho okubonakalayo okungenakuqhathaniswa kumuntu oyifakile!
● Umkhakha wokubuka obanzi: ogqokile angathola ukubona okucacile okuqhubekayo kusukela endaweni ekude kuya endaweni eseduze ngokusebenzisa ilensi ye-multifocal eqhubekayo, futhi angabona amabanga akude, amaphakathi namafushane ngokucacile.
● Ukubona okunamandla kucace kakhudlwana : lapho ukukhanya kuhamba endaweni ethile kuya kwenye, inqubo yokulungisa iso ingokwemvelo, futhi ngeke kubangele isiyezi nokungaboni kahle ngenxa yokugxuma izithombe.
● Ukunethezeka okukhulu: ukubona kwemvelo, ngokuhambisana ne-physiological optics, ukuzijwayeza ngokushesha kanye nokunciphisa isikhathi sokujwayela
● Ukubukeka kusemfashinini kakhulu: ukubukeka kuhle kakhulu kune-bifocals, awukho umugqa ohlukanisayo wefilimu encane, futhi ayikho indawo eyimpumputhe yonyaka.
Bheka eduze futhi ubone kude, isibuko esisodwa sokusetshenziswa okuningi, umsebenzi wokulungisa umbono, ukugqoka kukhululeke kakhudlwana
Ukuhambisa idizayini eqhubekayo endaweni engaphakathi kwandisa kakhulu inkambu yokubuka yendawo ngayinye yelensi.Esinye isici esithinta insimu yokubuka sivela kumklamo we-aspheric noma we-astigmatic aspheric ongemuva.Idizayini ye-aspheric yenza iradiyasi ye-cur vature ye-apex yelensi flat ukuze ilensi ikwazi ukusondela ebholeni leso, okuphinde kube yisici esibalulekile ekwandiseni inkundla yokubuka.
Incazelo ilensi
Yamukela isimiso somklamo othambile we-asymmetric ukuze uhlangabezane nebhalansi yokude, phakathi nendawo naseduze
Futhi indawo ye-astigmatism nhlangothi zombili ithuthukiswe ngempumelelo ukuze kukhuliswe indawo yokubuka yamalensi ngo-35%
Futhi kwenza ogqokile azizwe ekhululekile ekushintsheni kwendawo ngayinye yokukhanya futhi kube lula ukuzivumelanisa nezimo.
