Izici zomkhiqizo
1) Kuyini amalensi we-biforal?
Ama-BIFOCAL amalensi anamandla amabili ahlukile wokulungisa. Ama-BIFOCAL ajwayele ukubekelwa ama-Presbywopes
Okudinga ukulungiswa kwe-MyOpia (Eseduze) noma i-Hyperopia (Ukudla kwasekuqaleni) noma ngaphandle kokulungiswa kwe-astigmatism (umbono osontekile ngenxa yelensi noma i-cornea). Inhloso eyinhloko yelensi ye-bifocal ukuhlinzeka ngebhalansi yokugxila efanelekile phakathi kwebanga nombono oseduze.
Ngokuvamile, ubheka phezulu naphezu kwebanga lelensi lapho ugxile ezindaweni ezikude, nawe
Bheka phansi nangengxenye ye-bifocal yelensi lapho ugxile ekufundeni okufundwayo noma izinto ezingaphakathi kweminyaka eyi-18
Amasentimitha angamehlo akho.Kuyemukelwa ngokuvamile ukuthi uBenjamin Franklin wasungula i-BIFOCAL. I-BIFOCAL evame kakhulu namuhla yi-BIFOCAL eqondile engama-28 ephezulu enomugqa oqondile ngaphezulu phezulu nge-28mm radius. Kunezinhlobonhlobo eziningana ze-BIfocals ephezulu eqondile etholakala namuhla kufaka phakathi: iqonde phezulu 25, iqonde phezulu 35, iqonde phezulu 45 kanye nesigungu esiphezulu (i-franklin seg) esebenza ububanzi obuphelele belensi.
Ngaphezu kokuhlobisa okuphezulu okuqondile kukhona ama-bIfocals ajikeleze ngokuphelele kufaka phakathi umjikelezo ongu-22, Round 24, Round 25
futhi kuhlanganiswe nxazonke ezingama-28 (akukho ngxenye echazayo).
Inzuzo yengxenye eyindilinga ukuthi kunesithombe esincane esigxuma njengenguquko eyodwa kusuka kude kuya engxenyeni eseduze yelensi.
2) Kuyini i-PhotoChromic Lens?
Ama-lens we-PhotoChromic ayaziwa nangokuthi "ama-lens we-photosensitive". Ngokwesisekelo sokuphendula okuguqukayo kokushintsha kombala okukhanyayo, i-lens ingashesha kancane kancane ngaphansi kwemisebe ekhanyayo ne-ultraviolet, vimba ukukhanya okuqinile bese kukhombisa ukuvalwa kokungathathi hlangothi, futhi kukhombisa ukungathathi hlangothi. Buyela ebumnyameni, ungabuyisela ngokushesha umbuso osobala ongenamibala, uqinisekise ukudluliselwa kwe-lens. Ngakho-ke ilensi eguqukayo yombala ilungele ukusetshenziswa kwangaphakathi nangaphandle ngasikhathi sinye, ukuvikela ukukhanya kwelanga, ukukhanya kwe-ultraviolet, glare kumonakalo wamehlo.photochromic lens nangokuthi "ama-lens photosesizitive". Ngokwesisekelo sokuphendula okuguqukayo kokushintsha kombala okukhanyayo, i-lens ingashesha kancane kancane ngaphansi kwemisebe ekhanyayo ne-ultraviolet, vimba ukukhanya okuqinile bese kukhombisa ukuvalwa kokungathathi hlangothi, futhi kukhombisa ukungathathi hlangothi. Buyela ebumnyameni, ungabuyisela ngokushesha umbuso osobala ongenamibala, uqinisekise ukudluliselwa kwe-lens. Ngakho-ke ilensi eguqukayo yombala ilungele ukusetshenziswa kwangaphakathi nangaphandle ngasikhathi sinye, ukuvikela ukukhanya kwelanga, ukukhanya kwe-ultraviolet, glare kumonakalo wamehlo.
3) Uyini umehluko phakathi kwe-HC, HMC ne-SHC?
| Ukuhlanganiswa kanzima | I-AR Coating / Hard Coating Multi | Super hydrophobic coating |
| kwenza ilensi engenalutho ilukhuni futhi yandisa ukumelana ne-abrasion | kwandisa ukudluliselwa kwelensi futhi kunciphisa ukuboniswa komhlaba | kwenza i-lens wantproof, i-antistatic, anti slip kanye nokumelana kawoyela |
