1.71 I-Single Vision HMC Optical lens
1.71 ilensi Igama eligcwele 1.71 refractive index lens, ne high refractive index, high transmittance, high Abbe inombolo izici, esimweni myopia degree efanayo, kunganciphisa kakhulu ukujiya lens, ukunciphisa izinga lens, ngesikhathi esifanayo. isikhathi, yenza i-lens ibe msulwa futhi igqame, akulula ukuhlakaza okusanhlamvu kothingo. Kutholakala ukuthi ukwengeza i-cyclic sulfide resin ku-lens kungathuthukisa inkomba ye-refractive ye-lens, kodwa i-cyclic sulfide resin eningi kakhulu izoholela ekunciphiseni ukudluliswa kokukhanya nokuqhekeka kwezinto ezibonakalayo. Ngokulawula ngokunembile okuqukethwe kwe-ring sulfur resin ku-1.71KR resin, ilensi engu-1.71 ifinyelela inkomba ephezulu ye-refractive kanye nenombolo ye-abbe kuyilapho iqinisekisa ukudluliswa kokukhanya okuhle, ukuhlakazeka okuphansi kanye nombono ocacile.

1.56 Umbono Owodwa we-HMC
I-lens, i-lens ibizwa nangokuthi isikhungo sesibuko, iyisikhungo sokudweba ngemva kokunyuka, esilungele ukugoqa ohlakeni lwesibuko, ngakho-ke kubizwa ngokuthi isikhungo sesibuko. Ifomu layo lingaba elivundlile, mpo, liwukufakwa okulula, okulula.
Ukuhlukaniswa: Amalensi angahlukaniswa abe yizinhlobo ezine ezilandelayo ngokuya ngezinto ezahlukahlukene:
Ilensi ye-resin lens ekhethekile yesikhala ilensi ilensi yengilazi

Izibuko zelanga ze-CR39 lens
Izibuko zelanga ziwuhlobo lwemikhiqizo yokunakekelwa kombono ukuvimbela ukulimala kwamehlo abantu okubangelwa ukukhanya kwelanga okunamandla. Ngokuthuthukiswa kwezinga lempahla yabantu kanye namasiko, izibuko zelanga zingasetshenziswa njengezesekeli ezikhethekile zobuhle noma isitayela somuntu siqu.

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

1.56 Amalensi abonakalayo e-HMC angcolile
Ilensi eqhubekayo iyilensi yobude obugxile ezintweni eziningi, ehlukile ezingilazini zokufunda ezivamile kanye nezibuko zokufunda ze-bifocal. Amalensi aqhubekayo awanakho ukukhathala kwamabhola wamehlo okumele alungise njalo ubude bokugxilile lapho kusetshenziswa ubude be-bifocal, futhi awukho umugqa osobala phakathi kobude bokugxilile okubili. umugqa wokuklama. Kukhululekile ukugqoka futhi kunokubukeka okuhle, futhi kancane kancane kuye kwaba yisinqumo esingcono kakhulu kubantu abane-presbyopia.
