1.56 I-Bifocal Flat top / Round Top / Amalensi abonakalayo e-HMC ahlanganisiwe

Incazelo emfushane:

Amalensi e-Bifocals amalensi ezibuko aqukethe zombili izindawo zokulungisa futhi asetshenziselwa ngokuyinhloko ukulungisa i-presbyopia. Indawo lapho ama-bifocal alungile ukubona kude ibizwa ngokuthi indawo yombono, kanti indawo elungisa eduze nendawo yokubona ibizwa ngokuthi eduze nendawo yombono kanye nendawo yokufunda. Ngokuvamile, indawo ekude inkulu, ngakho ibizwa nangokuthi ucezu oluyinhloko, futhi indawo eseduze incane, ebizwa ngokuthi i-sub slice.

Kunamadigri amabili kuphela kulensi ye-bifocales, ezihlukaniswe zibe ukukhanya okuphezulu nokukhanya okuphansi. Kokubili ukukhanya okungaphezulu nokukhanya okuphansi kungaba i-myopia, i-hyperopia, i-astigmatism, njll., kodwa ukukhanya okungaphezulu kujulile kunokukhanya okungaphezulu kwe-myopia futhi akujulile ngokubona kude.

I-Progressive ithuthukiswa ngesisekelo sokukhanya okuphindwe kabili. Ayinayo nje izici zokukhanya okuphindwe kabili, okuhlanganisa ukukhanya okuphezulu nokukhanya okuphansi, kodwa futhi inenqubo ehamba kancane phakathi. Idigri phakathi kokukhanya okuphezulu nokukhanya kwaphansi kuyinqubo yokushintsha kancane kancane.

Phezulu, kusobala ukubona umehluko phakathi kokukhanya okuphindwe kabili. Umugqa ohlukanisayo noma ukuhlangana phakathi kokukhanya okungaphezulu nokukhanya okuphansi kungabonakala, kodwa ingaphezulu lelensi eqhubekayo aliboni noma yimuphi umehluko.

Ngezoni yoshintsho, ayikho inkinga yokugxuma kwendlovu. Okungukuthi, kancane kancane ukusuka kude kuye eduze, kusuka eduze kuya kude, uma ingekho indawo yoguquko, ukusuka eduze kuya kude, kusuka kude kuya eduze, akukho kudubula kwe-buffer overshoot.

Isingeniso Sokukhiqiza

I-Bifocal ibhekisela emandleni amabili e-dioptric ahlukene kwilensi efanayo, amandla amabili e-dioptricyizo dibekwe ezindaweni ezihlukene zelensi, indawo esetshenziselwa ukubona kude ibizwa ngokuthi indawo yebanga, etholakala engxenyeni engenhla yelensi; indawo esetshenziselwa ukubona eduze ibizwa ngokuthi indawo eseduze, etholakala engxenyeni engezansi yelensi.

Izinzuzo zama-bifocals: Ungabona izinto ezikude endaweni yokubona ekude yepheya lamalensi, futhi ungabona izinto ezikude endaweni yombono eseduze yamalensi afanayo. Awudingi ukuphatha amapheya amabili ezingilazi nawe, futhi awudingi ukushintsha phakathi kwebanga nezibuko njalo.

Ububi be-bifocals: Inkambu yokubuka incane kunaleyo yamalensi anombono owodwa, ikakhulukazi eduze nokubona. Isibonelo, ukufunda izincwadi namaphephandaba kudinga ukubambisana nokunyakaza kwekhanda. Kukhona ukukhubazeka kokubona kokugxuma kanye nokususwa kwesithombe, futhi kukhona umugqa ohlukanisayo, okulula ukubonakala ugqoke. Veza iminyaka nge-bifocals.
