Izibuko zingamalensi ashumekwe ohlakeni futhi agqokwa phambi kwamehlo ukuze avikeleke noma ahlobise.Izibuko zingasetshenziswa futhi ukulungisa izinkinga ezihlukahlukene zokubona, okuhlanganisa ukubona eduze, ukubona kude, i-astigmatism, i-presbyopia noma i-strabismus, i-amblyopia nokunye.
Ngakho wazini ngamalensi?Ungakhetha kanjani i-lens evumelana nawe?Ake siqale ngezinto ezintathu:
I-Lens Transmittance: Lapho i-transmittance iphezulu, kuba ngcono ukucaca
Uhlobo lwamalensi:
Shintsha ilensi yombala: shintsha ilensi yombala ingalungisa ukudluliselwa ngombala wokushintsha ilensi, yenza iso lomuntu livumelane nokushintsha kwendawo, yehlise ukukhathala okubukwayo, ivikele iso.
I-high refractive index lens: Uma iphezulu inkomba ye-refractive, i-lens iba mncane.
Amalensi aqhubekayo: Avumelane nazo zonke izimo namabanga
Ilensi yengilazi:
Iyakwazi ukumelana nokuklwebheka kunamanye amalensi, kodwa inzima kakhulu.
I-polymer resin lens:
Ilula kunama-lens engilazi, ukumelana nomthelela akulula ukuphuka, kodwa ukuqina kuphansi, kulula ukukunwaya.
Amalensi e-PC:
Igama lamakhemikhali e-PC yi-polycarbonate, enokuqina okuqinile, eyaziwa nangokuthi "isiqephu sesikhala", "isiqephu sendawo yonke", "i-lens yokuphepha", akulula ukuphuka.Inesisindo esiwuhhafu kuphela njengesamalensi e-resin endabuko, futhi asetshenziswa kakhulu kumalensi abona kafushane ezingane noma imaski yamehlo yabasubathi.
Isibani esiluhlaza okwesibhakabhaka:
Ucwaningo luye lwathola ukuthi ukukhanya okuluhlaza okwesibhakabhaka kungabangela ukulimala okungapheli ku-retina, kubangele ukuwohloka kwe-macular.Manje ukukhanya okuluhlaza sekugcwele emithonjeni yokukhanya yokwenziwa.I-anti blue light lens ingavikela amehlo, inciphise umonakalo odalwe yikhompyutha nomthombo wokukhanya we-LED.
I-Polarization:
Izici zokukhanya kwe-polarized ngokuvamile ukuqeda ukukhanya okubonisiwe nokukhanya okuhlakazekile, ukuvimba ukukhanya okunamandla, ukuhlukanisa ukukhanya okuyingozi kwe-ultraviolet, umthelela obonakalayo ucace kakhudlwana, ukumelana nomthelela, ukumelana nokuklwebheka.
Ukufakwa kwelensi:
Inganciphisa ukukhanya okubonakalayo kwendawo ye-lens, yenze into icace, inciphise ukukhanya kwesibuko, ikhulise ukudluliswa kokukhanya.
