Umehluko phakathi kombono owodwa kanye nama-lens we-biforal: ukuhlaziya okuphelele

Ama-lens ayinto ebaluleke kakhulu ekwakhiweni kombono futhi aza ngezinhlobo ezahlukahlukene ngokuya ngezidingo ezithile zomthwali. Amalensi amabili asetshenziswa kakhuluAmalensi wombono owodwana-amalensi we-bifocal. Ngenkathi bobabili besebenza ukulungisa ukungasebenzi kahle okubukwayo, benzelwe izinhloso ezahlukahlukene kanye nabantu. Ukuqonda umehluko phakathi kwalawa ma-lens kubalulekile ekwenzeni isinqumo esinolwazi, ikakhulukazi ukuthi umbono wabantu udinga ukushintshana ngeminyaka nezimfuno zendlela yokuphila. Kulokhu kuhlaziywa okuningiliziwe, sizohlola umehluko phakathi kombono owodwa namalensi we-biforal, kufaka phakathi izinhlelo zabo, izinzuzo, nokuthi babhekana kanjani nezinkinga ezithile zombono.

1. Amalensi wombono owodwa: Ayini?

Ama-lens wombono owodwa alula futhi asetshenziswa kakhulu amalensi ezihlokweni ze-eyeglass. Njengoba igama libonisa, la ma-lens aklanyelwe ukuqondisa umbono ngobude obuphelele. Lokhu kusho ukuthi banamandla okulungiswa okufanayo kulo lonke uhlangothi lwelensi, okwenza balungele ukubhekana nohlobo oluthile lwephutha lokuphindaphinda - nomaEseduze (Myopia)nomaUkuzikhethela (i-hyperopia).

Izici ezibalulekile:

• Amandla afanayo: Ilensi inamandla okunikezwa kadokotela kulo lonke, igxile ekukhanyeni endaweni eyodwa e-retina. Lokhu kuvumela umbono ocacile ebangeni elilodwa.
• Ukusebenza okwenziwe lula: Ngenxa yokuthi amalensi wombono owodwa alungile ngohlobo olulodwa lwenkinga yombono, aqondile ekwakhiweni nasekukhiqizweni.

• Nge-hyperopia (ekufeni): Abantu abanokubanda okulwa kanzima ukuze babone izinto eziseduzane kahle. Amalensi wombono owodwa we-hyperopia agxila kakhulu ku-retina, ethuthukisa eduze nombono.

Sebenzisa amacala:

Amalensi wombono owodwa nawo angasetshenziselwa abantu abane-astigmatism, isimo lapho ama-cornea angena khona ngokungafanele, okuholela embonweni ohlanekezelwe kuwo wonke amabanga. Amalensi akhethekile wombono abizwa ngokuthiamalensi e-toricbayenzelwe ukulungisa i-astigmatism.

Izinzuzo zamalensi wombono owodwa:

1. Idizayini elula nokukhiqiza: Ngoba la ma-lens aklanyelwe ukuqondisa umbono ngebanga elilodwa kuphela, kulula futhi abiza kakhulu ukukhiqiza kunamalensi amaningi.
2. Uhla olubanzi lwezicelo: Ama-lens wombono owodwa ahlukahlukene futhi alungele abantu bayo yonke iminyaka enohlobo olulodwa lwephutha lokuqapha.
3. Izindleko eziphansi: Ngokuvamile, ama-lens wombono owodwa abiza kakhulu kune-bifocal noma ama-lens athuthukayo.
4. Ukuguqulwa okulula: Ngoba ilensi yonke iyunifomu emandleni ayo okulungiswa, abagqoke ama-lens wombono owodwa abazivumelanisa nabo kalula ngaphandle kokuthola ukuhlanekezela noma ukungaphatheki kahle.
5. Ububanzi bokugxila okulinganiselwe: Ama-lens wombono owodwa alungisa kuphela uhlobo olulodwa lwenkinga ye-Vision (eduze noma kude), engase anganele kubantu abakhulisa ama-presbybyopia noma ezinye izimo ezihlobene nobudala ezithinta zombono eduze nasekude.
6. Izinguquko ezijwayelekile ze-eyeglass: Okwabantu abadinga ukulungiswa kwazo zombili imisebenzi yebanga nemisebenzi yokusondelana (isib. Ukufunda nokushayela), amalensi wombono owodwa angadinga ukushintshwa phakathi kwamabhangqa ahlukene ezingilazi, okungaphazamisa.

Ukukhawulelwa kwamalensi wombono owodwa:

2. Amalensi we-Bifocal: Ayini?

Ama-lens we-biforal aklanyelwe ngqo abantu abadinga ukulungiswa kubo bobabiliUmbono webangana-eduze nombono. Lawa ma-lens ahlukaniswe izigaba ezimbili ezihlukile: ingxenye eyodwa yokubona izinto ezikude ngokusobala, kanti enye ikhona ngokubona izinto eziseduze, njengalapho zifunda. Ama-bifocals ngokwesiko adalelwa ukubhekanaPresbyopia, isimo lapho iso lilahlekelwa amandla alo okugxila ezintweni eziseduze njengabantu ubudala.

 Izici ezibalulekile:

• Imiyalelo emibili elensi eyodwa: Amalensi we-biforal anamandla amabili ahlukene wokulungisa elensi eyodwa, imvamisa ehlukaniswe umugqa obonakalayo. Ingxenye ephezulu yelensi isetshenziselwa umbono webanga, ngenkathi ingxenye engezansi isetshenziselwa ukufunda noma eminye imisebenzi eseduze.
• Umugqa ohlukile wokuhlukanisa: I-BIFOCALS yendabuko inomugqa noma ijika elihlukanisa izindawo ezimbili zombono, okwenza kube lula ukushintsha phakathi kwebanga kanye nokufunda imiyalo ngokumane uhambisa amehlo phezulu noma phansi.
• Ye-presbyopia: Isizathu esivame kakhulu abantu abagqoke ama-lens se-biforal ukulungisa ama-Presbyopia. Lesi simo esihlobene nobudala siqala ukuthinta abantu ema-40s abo nama-50s, okwenza kube nzima ngabo ukugxila ezintweni eziseduzane, njengalapho befunda noma befunda i-smartphone noma besebenzisa i-smartphone noma besebenzisa i-smartphone noma besebenzisa i-smartphone.
• Ngokulungiswa kombono okufanayo: Ama-bifocals alungele abantu abadinga ukushintsha kaningi phakathi kokubuka izinto ezikude (njengokushayela noma ukubuka i-TV) nokwenza ikhompyutha esondelene (njengokusebenzisa ikhompyutha). Idizayini emibili-e-One ibavumela ukuba benze lokhu ngaphandle kokushintsha izibuko.

Sebenzisa amacala:

Izinzuzo zamalensi we-bifocal:

1. Isixazululo esilula sesibili: Ama-BIFOCALS aqeda isidingo sokuthwala amabhangqa amaningi ezingilazi. Ngokuhlanganisa ibanga kanye nokulungiswa kombono embonini eyodwa, banikeza ikhambi elisebenzayo kulabo abane-presbyopia noma ezinye izidingo zombono ezigxile ezimalini.
2. Umsebenzi obonakalayo owenziwe ngcono: Okwabantu abadinga umbono ocacile ekuqaleni kwebanga kanye nobubanzi, ama-bifocals anikela ngentukuthelo esheshayo ekusebenzeni kwansuku zonke ngaphandle kokuhlupheka kwezibuko ezishintsha njalo.
3. Kubiza kakhulu uma kuqhathaniswa nokuthuthuka: Ngenkathi ama-benses e-biforal abiza kakhulu kunelensi yombono owodwa, ngokuvamile abiza kakhulu kunama-lens athuthukile, ahlinzeka ngoguquko olubushelelezi phakathi kwezindawo ezihlukile ezigxile.
4. Ukuhlukaniswa okubonakalayo: Enye yezici eziphawuleka kakhulu zamalensi we-bifocal umugqa obonakalayo ohlukanisa izindawo ezimbili zombono. Abanye abasebenzisi bathola lokhu kungathandeki kahle, futhi kungakha nomphumela "we-jump" umphumela lapho ushintsha phakathi kwezindawo ezimbili.
5. Umbono olinganiselwe olinganiselwe: Ngokungafani nama-lens athuthukile, ama-bifocals anezindawo ezimbili kuphela ezinikezwayo - ibanga futhi eduze. Lokhu kushiya igebe lombono ophakathi nendawo, njengokubuka isikrini sekhompyutha, esingaba yinkinga yemisebenzi ethile.
6. Isikhathi sokulungiswa: Abanye abasebenzisi bangathatha isikhathi ukujwayela ushintsho olungazelelwe phakathi kwezindawo ezimbili ezigxile kakhulu, ikakhulukazi lapho ushintsha phakathi kwebanga nangombono osondele njalo.
