Yintoni inkqubela yangaphakathi kunye nenkqubela phambili yangaphandle?
Iinkqubo zangaphandle
Ilensi eqhubelekayo yangaphandle ikwabizwa ngokuba yilensi yoyilo lomphezulu ohamba phambili, oko kukuthi indawo yegradient yamandla ibekwe kumphezulu ongaphambili welensi, kude lee emehlweni.
I-Inner Progressives
I-Inner progressive ikwabizwa ngokuba yi-back surface design lens progressive, olu hlobo lwelensi eqhubekayo lubhekiselele kusetyenziso lwetekhnoloji yomphezulu wefomu yasimahla kunye nezixhobo zokusetyenzwa kwelathe ukubeka uyilo lwesidanga (umphezulu osebenzayo) kumphezulu ongasemva, kufutshane namehlo.
Umahluko wemveliso phakathi kwenkqubela yangaphakathi kunye nenkqubela yangaphandle
Oi-uter progressiveiilensi zenziwa kusetyenziswa indibaniselwano yeendlela ezimbini zokusetyenzwa.
1. Ukuqhubekeka kokuqala
I-ADD kunye ne-corridor ubude bomphezulu wangaphandle ziyilwe kwi-front surface mold ye-lens, kwaye i-mold kwi-face surface ye-lens ayinalo utshintsho kwi-curvature photometric.I-lens substrate kunye ne-ADD iveliswa yi-molds ezimbini usebenzisa umgca wendibano, ozinikele kwiilensi eziqhubekayo.I-Substrate, kungekhona ukusetyenziswa kwimveliso yezinye iintlobo zeelensi.Ngokuqhelekileyo ukuveliswa kwee-substrates ezinjalo kufuneka kuhambelane ne-ADD nganye, ngoko ke uluhlu lokugcina lwe-substrates lukhulu kakhulu.
2. Ukuqhubekeka okwesibini
Ukusuka kwisitokhwe seelensi eziveliswe yinkqubo yokuqala, fumana iilensi ze-UC kunye ne-ADD efunekayo, kwaye uyitshise ngasemva kwelensi ukufezekisa amandla akude.Emva kwala manyathelo mabini okucubungula, ipere yeelensi eziqhubekayo ziyagqitywa.
I-Inner progressive, indawo yayo ye-gradient ibekwe kwindawo yangaphakathi yelensi, kwaye iziko layo likwabekwe kwindawo yangaphakathi yelensi.Umphezulu wayo wangaphandle wamkela uyilo olufanayo olungqukuva okanye oluyi-aspheric njengeelensi zombono omnye eziqhelekileyo.
Ngokwahlukileyo kwitekhnoloji yokucutshungulwa kwendabuko, i-lens yangaphakathi ye-free-form yangaphakathi inokuqulunqwa ngokwenkqubo yekhompyuter, kwaye yamkele uyilo oluhlanganisiweyo lokubumba.Ngoncedo lwetekhnoloji yokucubungula "i-soft polishing", inkqubo yokuguqulwa kwedijithali ephezulu yendawo yangasemva ye-lens inokugcinwa ngokupheleleyo.Uyilo lwangaphambili oluqhubekayo.
