Ukusetyenziswa kwelensi yegaraji
1. Ukucutshungulwa okukhethekileyo kwe-photometric: njenge-myopia ephezulu, i-hyperopia ephezulu, i-astigmatism ephezulu, iilensi ezikhethekileyo zeprism, njl. Umzekelo, ukukhanya okuphezulu kwe-lens engathandekiyo yayingu-24.00DS kunye nesibuko sekholomu edibeneyo -4.00D.Iilensi ze-Ortho zilungiselelwe ukuya kuthi ga kwi +13.00DS.Isibuko sekholomu esidityanisiweyo sinokwenziwa ngokwezifiso + 6.00DC.
2. Ukulungiswa komphezulu okhethekileyo: i-spherical, i-aspherical, i-aspherical enamacala amabini, iprosesa ye-lens eqhubekayo kunye nokukhanya okwahlukileyo, idizayini eyahlukileyo yoyilo lomphezulu oqhubekayo, kunye noyilo olwahlukileyo lwangaphakathi nangaphandle.Ngenxa yokuba uyilo lwelensi yeentlobo ezahlukeneyo zobuso luya kuzisa iimvakalelo ezahlukeneyo zokubonwayo, inokubonelela ngezisombululo ezihambelanayo kubantu abaneemfuno ezahlukeneyo zokubonwa.
3. Ifilimu ekhethekileyo yokugquma;Ukufezekisa iimfuno ezahlukeneyo zokwenza ifilimu ekhethekileyo.Ngokomzekelo, yongeza ifilimu ye-dural, ifilimu ye-anti-antireflection, ifilimu ye-hydrophobic, njl.
4. I-Mei-thin machining: I-Mei-thin machining yi-lens ene-diameter ekhethekileyo echaziweyo, elungiselelwe ukunciphisa ubukhulu beziko le-lens ephilileyo kunye nobukhulu bomphetho we-lens ongalunganga.Iilensi zoomatshini eziyilwe ngokwesiko ngokwendalo.Ngokomyalelo kunye nemilo kunye nobukhulu besakhelo, iteknoloji yokucubungula kunye nobukhulu obungcono kakhulu yamkelwa, kwaye ubukhulu obufanelekileyo be-lens bubalwa yi-software yobuchwephesha, ukwenzela ukuba iiglasi zibe zihle kakhulu.Ngokwesiqhelo, inkqubo yokwenza ngokwezifiso yelensi yegaraji inokufikelela kwiimfuno zobuhle kunye nokuncipha kwelensi ngoyilo lobubanzi, uyilo lwe-eccentricity, uyilo lwenkqubo yomphezulu welensi njalo njalo.
5. Ukudaya ukudaya: ngokweemfuno ezihambelanayo, umbala opheleleyo, umbala oqhubekayo, umbala ngamnye, ukudaya kokukhanya kwepolarized kunye nokunye ukusetyenzwa.
6. Isiseko esikhethekileyo se-lens egobileyo: yenza ngokwezifiso isiseko esikhethekileyo se-lens egobileyo ukulungelelanisa kwisakhelo esikhethekileyo sokugoba.Umzekelo, abantu befashoni basebenzisa ezinye iifreyimu zelanga ukwenza iiglasi zelanga eziyimyopic.Ngokwesakhelo sesakhelo kunye nedatha ye-optometry kagqirha, nceda umntu onxibileyo ukuba ayile i-lens ye-lens surface bend, yenza i-lens ihambelane nesakhelo, ukwenzela ukuba umntu onxibileyo abonise umphumo ofanelekileyo wokunxiba.Ngokomzekelo, kwi-lens ye-4.00D efanayo, indawo yangaphambili ye-+500 ukujika kunye nomgangatho ongemva we-100 ujika unokukhethwa, kunye nobuso obuphambili be- +600 ukujika kunye nobuso obungasemva be-200 ukujika kwakhona kunokukhethwa. .Ubume kunye nobukhulu be-lens buhluke ngokupheleleyo phakathi kwezicwangciso ezimbini.

Inkqubo yokuvelisa ilensi yesiko egaraji
Inkqubo ikakhulu ibandakanya ukuqokelelwa kweodolo, ukubalwa kwedatha esisiseko, ukhetho lweemveliso ezigqityiweyo, ukuqinisekiswa kwedatha esisiseko, ukubalwa kobume bomphezulu ongemva, ifilimu ekhuselayo kwisiseko sokugoba, ukhetho lokungunda, i-sucker engaguqukiyo, ukusila ngokurhabaxa. ubume bendawo yangasemva, ukugaya kakuhle kunye nokupolisha kwendawo yangasemva, ukuhlolwa kokukhulula, ukudaya kunye nefilimu enzima, ukuhlolwa komgangatho wokugqibela, ukuhanjiswa kunye nezinye iinkqubo.

Amanqaku okuLungisa
1. Kucetyiswa ukuba zombini iilensi zenziwe ngokwesiqhelo xa kunokwenzeka.Ngokomzekelo, kwimeko ye-anisometropia, i-lens enye -8.00DS ilungiselelwe nge-lens ephezulu ye-refractive index, ngelixa i-lens enye -4.00DS iyinto eqhelekileyo ye-lens engekho ngokwezifiso.Kule meko, ubukhulu beziko, umbala wemvelaphi ye-lens kunye ne-optical imaging effect inokwahluka phakathi kwe-lens eyenziwe ngokwezifiso kunye ne-lens engeyiyo ngokwezifiso.Ngoko ke, kumbono wempilo ebonakalayo, kucetyiswa ukuba usebenzise igaraji efanayo ukwenza iilensi ngokwezifiso ukuba kunokwenzeka.
2. Malunga negaraji, ubukhulu, ubukhulu beziko le-lens ngenxa yeelensi ezinqabileyo kakhulu, ngakumbi i-lens ephezulu yegaraji ye-myopia esebenzisa imveliso yokusila, ngokusebenzisa i-lens embindini wobunzima bemveliso yokusila ngokuqinisekileyo iya kuba ngqindilili kunoko. ngokuveliswa kokungunda, kuba ukuba umhlaba ubhityile, ukukhanya kokuqala kungenakukwazi ukulawula, i-lens yesibini yaphukile ngokulula.
