1.56 I-Bifocal Flat top / Round Top / Amalensi e-HMC optical ahlanganisiwe Isithombe Esifakiwe

Incazelo emfushane:

Amalensi e-Bifocal angamalensi ezibuko aqukethe zombili izindawo zokulungisa futhi asetshenziswa kakhulu ekulungiseni i-presbyopia. Indawo lapho ama-bifocal elungisa khona umbono okude ibizwa ngokuthi indawo yombono okude, kanti indawo elungisa indawo yombono oseduze ibizwa ngokuthi indawo yombono oseduze nendawo yokufunda. Ngokuvamile, indawo ekude inkulu, ngakho-ke ibizwa nangokuthi isilayi esiyinhloko, kanti indawo eseduze incane, ebizwa ngokuthi isilayi esincane.

Kunamazinga amabili kuphela ku-lens ye-bifocales, ezihlukaniswe ngokukhanya okuphezulu nokukhanya okuphansi. Kokubili ukukhanya okuphezulu nokukhanya okuphansi kungaba yi-myopia, i-hyperopia, i-astigmatism, njll., kodwa ukukhanya okuphezulu kujule kunokukhanya okuphezulu kwe-myopia futhi kuncane kakhulu kokubona kude.

I-Progressive ithuthukiswa ngokusekelwe ekukhanyeni okuphindwe kabili. Ayinazo nje kuphela izici zokukhanya okuphindwe kabili, okuhlanganisa ukukhanya okuphezulu nokukhanya okuphansi, kodwa futhi inenqubo eqhubekayo phakathi nendawo. Izinga eliphakathi kokukhanya okuphezulu nokukhanya okuphansi kuyinqubo yokushintsha kancane kancane.

Ebusweni, kusobala ukubona umehluko phakathi kokukhanya okuphindwe kabili. Umugqa ohlukanisayo noma indawo ehlangana khona phakathi kokukhanya okuphezulu nokukhanya okuphansi ungabonakala, kodwa ubuso belensi eqhubekayo abukwazi ukubona umehluko.

Ngendawo yokuguquka, ayikho inkinga yokugxuma kwendlovu. Okusho ukuthi, kancane kancane ukusuka kude kuya eduze, ukusuka eduze kuya kude, uma kungekho ndawo yokuguquka, ukusuka eduze kuya kude, ukusuka kude kuya eduze, akukho ukugxuma okungaphezulu kwe-buffer.

Isingeniso Sokukhiqiza

I-Bifocal ibhekisela emandleni amabili ahlukene e-dioptric kulensi efanayo, amandla amabili e-dioptrickukhona dNjengoba isatshalaliswe ezindaweni ezahlukene zelensi, indawo esetshenziswa ukubona kude ibizwa ngokuthi indawo yebanga, etholakala engxenyeni engenhla yelensi; indawo esetshenziswa ukubona eduze ibizwa ngokuthi indawo eseduze, etholakala engxenyeni engezansi yelensi.

Izinzuzo zama-bifocal: Ungabona izinto zikude ngokusebenzisa indawo yokubona ekude yamalensi amabili, futhi ungabona izinto zikude ngokusebenzisa indawo yokubona eseduze yamalensi afanayo. Akudingeki uphathe ama-pair amabili ezibuko nawe, futhi akudingeki ushintshe phakathi kwebanga nezibuko eziseduze njalo.

Okubi ngama-bifocal: Insimu yokubuka incane kuneyama-lens anombono owodwa, ikakhulukazi eduze kombono. Isibonelo, ukufunda izincwadi namaphephandaba kudingeka kusebenzisane nokunyakaza kwekhanda. Kunezinkinga zokubona zokugxuma kanye nokugudluka kwesithombe, futhi kukhona umugqa ohlukanisayo, okulula ukuwubona ugqoke. Veza ubudala ngama-bifocal.
