1.56 Umphezulu weFlethi yeBifocal / Umphezulu oRounding / Iilensi ezibonakalayo zeHMC eziDityanisiweyo

1.56 Umphezulu we-Bifocal Flat / Umphezulu oRawundi / Iilensi ezibonakalayo ze-HMC eziDityanisiweyo

Inkcazelo emfutshane:

IiLensi zeBifocals ziilensi zokubukela eziqulathe zombini iindawo zokulungisa kwaye zisetyenziselwa ikakhulu ukulungisa i-presbyopia. Ummandla apho ii-bifocals zichanekileyo zokubona kude kuthiwa yi-far vision area, kwaye ummandla olungisa kufuphi nendawo yombono ubizwa ngokuba kufuphi nendawo yombono kunye nendawo yokufunda. Ngokuqhelekileyo, indawo ekude inkulu, ngoko ikwabizwa ngokuba sisilayi esiphambili, kwaye indawo ekufutshane incinci, ebizwa ngokuba yi-sub slice.

Kukho izidanga ezimbini kuphela kwilensi ye-bifocales, ezahlulwe zibe kukukhanya okuphezulu kunye nokukhanya okuphantsi. Kokubini ukukhanya okungaphezulu kunye nokukhanya okusezantsi kunokuba yi-myopia, i-hyperopia, i-astigmatism, njl., kodwa ukukhanya okuphezulu kunzulu kunokukhanya okuphezulu kwe-myopia kunye nokungaboni kakuhle.

Inkqubela phambili iphuhliswa ngesiseko sokukhanya kabini. Ayinayo kuphela iimpawu zokukhanya okuphindwe kabini, kubandakanywa ukukhanya okuphezulu kunye nokukhanya okuphantsi, kodwa kunenkqubo encinci phakathi. Iqondo phakathi kokukhanya okuphezulu kunye nokukhanya okuphantsi yinkqubo yokutshintsha ngokuthe ngcembe.

Kumphezulu, kucacile ukubona umahluko phakathi kokukhanya kabini. Umgca wokuhlula okanye ukudibanisa phakathi kokukhanya okungaphezulu kunye nokukhanya okuphantsi kunokubonwa, kodwa umphezulu we-lens oqhubekayo awukwazi ukubona nawuphi na umahluko.

Ngommandla wenguqu, akukho ngxaki yokutsiba kweendlovu. Oko kukuthi, ngokuthe ngcembe ukusuka kude ukuya kufutshane, ukusuka kufutshane ukuya kude, ukuba akukho ndawo yotshintsho, ukusuka kufutshane ukuya kude, ukusuka kude ukuya kufutshane, akukho buffer overshoot.

Intshayelelo yeMveliso

I-Bifocal ibhekisa kumandla amabini ahlukeneyo e-dioptric kwilensi enye, amandla amabini e-dioptricngaba difakwe kwiindawo ezahlukeneyo zelensi, indawo esetyenziselwa ukubona kude ibizwa ngokuba yindawo yomgama, efumaneka kwisiqingatha esiphezulu selensi; indawo esetyenziselwa ukubona kufutshane ibizwa ngokuba ngummandla okufutshane, okwisiqingatha esisezantsi selensi.

Izinto eziluncedo kwii-bifocals: Uyakwazi ukubona izinto ezimgama kwindawo yombono ekude kwiperi yeelensi, kwaye unokubona izinto ezikumgama osondeleyo kwindawo yombono ekufutshane yeperi le lens enye. Awudingi ukuba uphathe iperi ezimbini zeeglasi kunye nawe, kwaye awudingi ukutshintsha phakathi komgama kunye neeglasi rhoqo.

Ububi be-bifocals: Indawo yokujonga incinci kunelensi zombono omnye, ngakumbi umbono okufutshane. Umzekelo, ukufunda iincwadi namaphephandaba kufuna ukusebenzisana nokushukuma kwentloko. Kukho iziphene zamehlo zokutsiba kunye nokufuduswa komfanekiso, kwaye kukho umgca wokuhlula, ekulula ukubonwa unxibe. Veza ubudala kunye ne-bifocals.
