I-SETO 1.56 I-Photochromic Round top bifocal Lens HMC/SHMC

SETO 1.56 Photochromic Round top bifocal Lens HMC/SHMC Isithombe Esifakiwe

Incazelo emfushane:

Njengoba igama liphakamisa ukuthi i-bifocal eyindilinga iyindilinga phezulu.Ekuqaleni zaziklanyelwe ukusiza abagqokile ukuthi bafinyelele indawo yokufunda kalula.Nokho, lokhu kunciphisa ububanzi bokubona eduze okutholakala phezulu kwesegimenti.Ngenxa yalokhu, ama-bifocal ayindilinga awaziwa kangako kune-D Seg.Ingxenye yokufunda ivame ukutholakala ngosayizi ongu-28mm no-25mm.I-R28 ingu-28mm ububanzi phakathi nendawo kanti i-R25 ingu-25mm.

Omaka:Ilensi ye-Bifocal, ilensi ephezulu eyindilinga, ilensi ye-photochromic, ilensi empunga ye-photochromic

Izici Zomkhiqizo

1) Yini ama-bifocal lens?
Ama-Bifocal amalensi anamandla amabili okulungisa ahlukene.I-Bifocals ivame ukunikezwa kuma-presbyopes
okudinga ukulungiswa kwe-myopia (ukubona eduze) noma i-hyperopia (ukubona kude) noma ngaphandle kokulungiswa kwe-astigmatism (ukubona okusontekile ngenxa yelensi emise ngendlela engavamile noma i-cornea).Injongo eyinhloko yelensi ye-bifocal ukunikeza ibhalansi yokugxila elungile phakathi kwebanga nokubona eduze.
Ngokuvamile, ubheka phezulu kanye nengxenye yebanga le-lens lapho ugxile emaphoyinti akude, nawe
bheka phansi futhi ngokusebenzisa ingxenye ye-bifocal yelensi lapho ugxile ezintweni zokufunda noma ezintweni ezingaphakathi kuka-18.
Amasentimitha wamehlo akho.Kuyamukelwa ngokuvamile ukuthi uBenjamin Franklin wasungula i-bifocal.I-bifocal evame kakhulu namuhla i-Straight Top 28 Bifocal enomugqa oqondile onqamula phezulu onerediyasi engu-28mm.Kunezinhlobo ezimbalwa zama-bifocal aphezulu aqondile atholakalayo namuhla okuhlanganisa: I-Straight Top 25, i-Straight Top 35, i-Straight Top 45 kanye ne-Executive (I-Franklin Seg yasekuqaleni) esebenzisa ububanzi obuphelele balensi.
Ngaphezu kwama-bifocal aphezulu aqondile kukhona ama-bifocal ayindilinga ngokuphelele ahlanganisa uRound 22, Round 24, Round 25
kanye Nomjikelezo Ohlanganisiwe 28 (ayikho ingxenye eqondile).
Inzuzo engxenyeni eyindilinga ukuthi kunokugxuma okuncane kwesithombe njengoba umuntu eshintsha ukusuka ebangeni ukuya engxenyeni eseduze yelensi.

2) Yini i-photochromic lens?
Amalensi e-Photochromic aziwa nangokuthi “amalensi azwelayo”.Ngokomgomo wokusabela okubuyisela emuva kokushintshana kombala okhanyayo, ilensi ingaba mnyama ngokushesha ngaphansi kwemisebe yokukhanya ne-ultraviolet, ivimbe ukukhanya okunamandla futhi imunce ukukhanya kwe-ultraviolet, futhi ibonise ukumuncwa okumaphakathi ekukhanyeni okubonakalayo.Ukubuyela ebumnyameni, kungabuyisela ngokushesha isimo esisobala esingenambala, siqinisekise ukudluliswa kwelensi.Ngakho-ke i-lens eshintsha umbala ifanele ukusetshenziswa kwangaphakathi nangaphandle ngesikhathi esifanayo, ukuvimbela ukukhanya kwelanga, ukukhanya kwe-ultraviolet, ukukhanya kwe-eye umonakalo.Amalensi e-Photochromic ayaziwa nangokuthi "ama-photosensitive lens".Ngokomgomo wokusabela okubuyisela emuva kokushintshana kombala okhanyayo, ilensi ingaba mnyama ngokushesha ngaphansi kwemisebe yokukhanya ne-ultraviolet, ivimbe ukukhanya okunamandla futhi imunce ukukhanya kwe-ultraviolet, futhi ibonise ukumuncwa okumaphakathi ekukhanyeni okubonakalayo.Ukubuyela ebumnyameni, kungabuyisela ngokushesha isimo esisobala esingenambala, siqinisekise ukudluliswa kwelensi.Ngakho-ke i-lens eshintsha umbala ifanele ukusetshenziswa kwangaphakathi nangaphandle ngesikhathi esifanayo, ukuvimbela ukukhanya kwelanga, ukukhanya kwe-ultraviolet, ukuxhomeka kokulimala kwamehlo.

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
