1.56 I-Bifocal Flat top / Round Top / Iilensi ze-HMC ezixutyiweyo

Inkcazo emfutshane:

Iilensi zeBifocals ziilensi zemiboniso eziqulathe zombini iindawo zokulungisa kwaye zisetyenziselwa kakhulu ukulungiswa kwe-presbyopia. Indawo apho ii-bifocals zilungisa khona umbono okude ibizwa ngokuba yindawo yombono okude, kwaye indawo elungisa indawo yombono okufutshane ibizwa ngokuba yindawo yombono okufutshane kunye nendawo yokufunda. Ngokwesiqhelo, indawo ekude inkulu, ngoko ke ikwabizwa ngokuba sisilayi esiphambili, kwaye indawo ekufutshane incinci, ibizwa ngokuba sisilayi esincinci.

Kukho iidigri ezimbini kuphela kwilensi ye-bifocales, ezahlulwe zibe kukukhanya okuphezulu nokukhanya okusezantsi. Zombini ukukhanya okuphezulu nokukhanya okusezantsi zinokuba yi-myopia, i-hyperopia, i-astigmatism, njl.njl., kodwa ukukhanya okuphezulu kunzulu kunokukhanya okuphezulu kwe-myopia kwaye kunzulu kunokukhanya okukude.

I-Progressive iphuhliswa ngokusekelwe kukukhanya okuphindwe kabini. Ayinazo nje kuphela iimpawu zokukhanya okuphindwe kabini, kuquka ukukhanya okuphezulu nokukhanya okusezantsi, kodwa ikwanayo nenkqubo eqhubekayo kancinci kancinci embindini. Iqondo eliphakathi kokukhanya okuphezulu nokukhanya okusezantsi yinkqubo yokutshintsha kancinci kancinci.

Kumphezulu, kuyacaca ukubona umahluko phakathi kokukhanya okuphindwe kabini. Umgca owahlulayo okanye indawo edibana kuyo ukukhanya okuphezulu nokukhanya okusezantsi unokubonwa, kodwa umphezulu welensi eqhubekekayo awunakubona mahluko.

Kwindawo yotshintsho, akukho ngxaki yokutsiba kwendlovu. Oko kukuthi, kancinci kancinci ukusuka kude ukuya kufutshane, ukusuka kufutshane ukuya kude, ukuba akukho ndawo yotshintsho, ukusuka kufutshane ukuya kude, ukusuka kude ukuya kufutshane, akukho ngxaki yokudlula kwe-buffer.

Intshayelelo yeMveliso

I-Bifocal ibhekisa kumandla amabini ahlukeneyo e-dioptric kwilensi enye, amandla amabini e-dioptricngaba dIsasazwe kwiindawo ezahlukeneyo zelensi, indawo esetyenziselwa ukubona kude ibizwa ngokuba yi-distance zone, ekwisiqingatha esiphezulu selensi; indawo esetyenziselwa ukubona kufutshane ibizwa ngokuba yi-near zone, ekwisiqingatha esisezantsi selensi.

Iingenelo ze-bifocals: Ungabona izinto zikude ngeendawo zokubona ezikude zeelensi ezimbini, kwaye ungabona izinto zikude ngeendawo zokubona ezikufutshane zeelensi ezifanayo. Akunyanzelekanga ukuba uphathe iiglasi ezimbini, kwaye akufuneki utshintshe phakathi komgama kunye neeglasi ezikufutshane rhoqo.

Iingxaki zee-bifocals: Indawo yokujonga incinci kunelensi zokubona enye, ingakumbi kufutshane nombono. Umzekelo, ukufunda iincwadi kunye namaphephandaba kufuneka kusebenzisana neentshukumo zentloko. Kukho iziphene zokukhanya zokutsiba kunye nokushenxa komfanekiso, kwaye kukho umgca owahlulayo, okulula ukuwubona unxibe. Bonisa ubudala nge-bifocals.
