Kodwa ngale kokuba ilensi nje ye-multifocal engenamigqa ebonakalayo, amalensi aqhubekayo enza abantu abane-presbyopia bakwazi ukubona ngokucacile futhi kuzo zonke izindawo.
Izinzuzo zamalensi aqhubekayo kune-bifocals
Amalensi ezibuko zamehlo ezi-bifocal anamandla amabili kuphela: elilodwa lokubona ngaphesheya kwegumbi kanti elinye lokubona eduze. Izinto eziphakathi, njengesikrini sekhompyutha noma izinto eziseshalofini lesitolo sokudla, zivame ukuhlala zingacacile ngama-bifocal.
Ukuze bazame ukubona izinto ezikulolu hlu "oluphakathi" ngokucacile, abagqoki be-bifocal kumele bagobise amakhanda abo phezulu naphansi, bebheka ngokushintshana phezulu nangaphansi kwe-bifocals yabo, ukuze banqume ukuthi iyiphi ingxenye yelensi esebenza kangcono.
Amalensi aqhubekayo alingisa kakhulu umbono wemvelo owawuwujabulela ngaphambi kokuqala kwe-presbyopia. Esikhundleni sokunikeza amandla amalensi amabili nje njenge-bifocals (noma amathathu, njenge-trifocals), amalensi aqhubekayo angamalensi "ama-multifocal" angempela ahlinzeka ngokuqhubeka okubushelelezi, okungenamthungo kwamandla amaningi amalensi ukuze abone ngokucacile egumbini, eduze nakuzo zonke izigaba eziphakathi.
Umbono wemvelo ongenawo "ukweqa isithombe"
Imigqa ebonakalayo kuma-bifocal nama-trifocal yizindawo lapho kuba khona ukuzuma. Futhi, ngenxa yenani elilinganiselwe lamandla amalensi kuma-bifocal nama-trifocal, ukujula kokugxila kwakho ngala malensi kunqunyelwe. Ukuze kubonakale ngokucacile, izinto kumele zibe ngaphakathi kobubanzi obuthile bamabanga. Izinto ezingaphandle kwamabanga ambozwe amandla amalensi e-bifocal noma e-trifocal zizofiphazwa futhi zishintshe emandleni amalensi.
Ngakolunye uhlangothi, amalensi aqhubekayo anokuqhubekela phambili okubushelelezi nokungenamthungo kwamandla elensi okubona ngokucacile kuwo wonke amabanga. Amalensi aqhubekayo anikeza ukujula kwemvelo kokugxila ngaphandle "kokugxuma kwesithombe."
Amandla amalensi aqhubekayo ashintsha kancane kancane kusukela endaweni kuya endaweni ebusweni belensi, okunikeza amandla afanele elensi okubona izinto ngokucacile cishe kunoma yiliphi ibanga.
Inikeza umbono ocacile kuwo wonke amabanga (kunokuba kube amabanga amabili noma amathathu kuphela ahlukene okubuka).
Ukuze uthole umbono omuhle kakhulu, induduzo kanye nokubukeka okuhle kakhulu, ungakhetha imihubhe ebanzi ukuze kube lula futhi kusheshe ukuzivumelanisa nezimo kunelensi eqhubekayo yesizukulwane esidlule.
