Bifocals ukusiza emehlweni

ukuthuthukiswa okuqhubekayo ubuchwepheshe yezokwelapha kwenza izigidi zabantu emhlabeni wonke ukuba siphinde sithole umbono wabo elahlekile futhi waphila ukuphila okugcwele. Enye yezindlela kungase kutholakale ukuba ubalekele presbyopia, okuyinto eyenzeka ngeminyaka e abantu abaningi ukusetshenziswa ngazimbili ezimbili noma ngaphezulu izibuko. Yiqiniso, lena akuyona njalo elula, futhi lapha basisize ka bifocals, obuhlanganisa property amabhangqa amabili.

Ngokuvamile, engxenyeni engaphezulu sengilazi lezi izibuko ukwazi ukubona izinto ezikude, futhi phansi - ukuhlukanisa izinto ukuthi sekuseduze by. Lezi izibuko izibuko kungaba, bese bifocals sibe trifocals noma multifocal.

Umqondo ekudalweni laphefumulelwa Ngokwemvelo, ezinye izinhlobo zezinhlanzi kufanele Bifocal emehlweni, okuvumela ezinhle ukubona izinto phansi kwesigubhu futhi ngesikhathi esifanayo asilandela eduze kusondela Izinyoni ezidla inyama phezulu. Kukholakala ukuthi bifocals wokuqala yasungulwa Bendzhamin Franklin, ngubani kuhlangene ngazimbili ezimbili izibuko kwelinye.

An ukuthuthukiswa ezithakazelisayo lo mbono aphakanyisiwe Usosayensi othile Israyeli Zeev Zalewski, ngubani kuhlangene ngengilazi ukuze izibuko bifocal kukhona lula kakhulu ukusebenzisa. izibuko lakhe Awekho umngcele omkhulu okhona phakathi izicabha. Khanyisa kubonakala kusukela akude naseduze izinto useyakwazi kwelinye ukusakaza okuqhubekayo, ehlanganisa yonke i-retina. Lokhu kuvumela ezinhle ngokulingana ukubona zonke izinto. Kulezi izibuko amehlo kancane okhathele, nayo kudingeka isikhathi esincane ukuzivumelanisa nazo.

isici esithakazelisayo Kwaphawulwa ovivinyweni lwabo. Kwavela ukuthi bangakwazi ukulungisa kokubili ongaboni kahle. Okungukuthi, lezi izibuko abakwazi kuphela ukubhekana nalesi yobudala izifo, ziwusizo kakhulu njengoba isilinganiso izifo.

Ukuthuthukiswa ubuchwepheshe okusezingeni eliphezulu futhi inikeza amathuba ezengeziwe ukuthuthukiswa mayelana nodaba ukulondolozwa. Ubani bahlakulele izibuko bifocal enguqulweni yayo electronic. Kulokhu, phakathi amafasitelana ezimbili ufakwa crystal isikrini uketshezi, usinika isithombe.

Endabeni version electronic bifocals konjiniyela bubekelwa inselele ukwandisa ikhwalithi yesithombe. Abathandwayo izinto ezintsha futhi ongakhetha ukwandisa noma ukunciphisa isithombe, futhi le autofocus. I prototypes lokuqala zinikezwa PixelOptics, yena baqhubeka nocwaningo lwakhe kule ndawo.

Ngemva kokuthintana nodokotela wakho, ungakwazi ukuthenga bifocals. intengo zabo iyahlukahluka kuye ngokuthi imikhiqizo yenkampani kanye nekhwalithi izimpahla. Kodwa into eyinhloko kule ndaba, it is kahle abakhethiwe imingcele amaphuzu anjalo. Kuleli kuncike lithathelwe yokugcina yesikhathi kungase kuthathe izinsuku eziyishumi emva ekuqaleni ukusetshenziswa.

Uma une isikhathi esiningi ukusebenza izinto eniseduze, ingilazi phansi kufanele kube indawo kunangendlela elingenhla. Futhi, ngokufanele, uma usebenza nge izifundo elikude, ukuthenga izibuko nge endaweni enkulu amafasitela engenhla. Lokhu kuzokusiza azivumelanise umkhiqizo omusha futhi waphila ukuphila okugcwele.
