I-SETO 1.499 I-Semi Finished Round top bifocal lens

Incazelo emfushane:

Ilensi ye-Bifocal ingabizwa ngokuthi ilensi enezinjongo eziningi.Inezinkambu ezi-2 ezihlukene zokubona kulensi eyodwa ebonakalayo.Ilensi enkulu ivamise ukuba nencwadi kadokotela edingekayo ukuze uyibonele ibanga.Kodwa-ke, lokhu kungaba futhi incwadi yakho kadokotela yokusetshenziswa kwekhompuyutha noma ibanga eliphakathi nendawo, njengoba ngokuvamile ubuzobheka uqonde lapho ubuka le ngxenye ethile yelensi.Ingxenye engezansi, ebizwa nangokuthi iwindi, ngokuvamile inencwadi yakho kadokotela yokufunda.Njengoba ngokuvamile ubheka phansi ukuze ufunde, lena indawo enengqondo yokubeka lolu hlu losizo lombono.

Omaka:1.499 Ilensi ye-Bifocal, ilensi eyindilinga eyindilinga engu-1.499, ilensi eyi-semi-finished eyi-1.499

Izici Zomkhiqizo

1) Yini ukubaluleka kwelensi enhle eqedwe kancane ekukhiqizeni i-RX?

a.Izinga eliphezulu elifanelekayo ekunembeni kwamandla nasekuzinzeni
b.Izinga eliphezulu eliqeqeshiwe kukhwalithi yezimonyo
c.Izici eziphezulu ze-optical
d.Imiphumela emihle yokufaka imibala kanye nemiphumela yokunamathela eqinile/yokunamathela kwe-AR
e.Qaphela umthamo omkhulu wokukhiqiza
f.Ukulethwa ngesikhathi
Hhayi nje ikhwalithi ekha phezulu, amalensi aqedwe kancane agxile kakhulu kukhwalithi yangaphakathi, njengamapharamitha anembayo futhi azinzile, ikakhulukazi kumalensi amahhala adumile.

2) Ayini ama-Bifocal Lens?

I-Bifocals yimiyalelo emibili ehlanganiswe ibe ilensi eyodwa.

Kunezinhlobo ezahlukene ze-bifocals ezitholakalayo, kusukela kwe-bifocal eyindilinga-phezulu, i-flat-top bifocal kuya kwe-bifocal ephezulu.

3) Uyini umehluko phakathi kwe-HC, HMC ne-SHC?

Ukugqoka okuqinile I-AR coating / Hard multi coating I-Super hydrophobic coating
yenza ilensi engamboziwe ibe lukhuni futhi ikhulise ukumelana nemihuzuko kwandisa ukudluliswa kwe-lens futhi kunciphisa ukubonakaliswa kwendawo yenza i-lens ingangeni manzi, i-antistatic, i-anti slip kanye nokumelana nowoyela
