Iiglasi ziilensi ezifakwe kwisakhelo kwaye zinxitywe phambi kwamehlo ukuze zikhuseleke okanye zihombise.Iiglasi zisenokusetyenziswa ukulungisa iingxaki ezahlukeneyo zokubona, eziquka ukubona kufutshane, ukubona kude, i-astigmatism, i-presbyopia okanye i-strabismus, i-amblyopia njalo njalo.
Wazi ntoni ke ngeelensi?Indlela yokukhetha i-lens ehambelana nawe?Masiqale ngezinto ezintathu:
I-Lens transmittance: Okukhona iphezulu i-transmittance, ingcono ukucaca
Uhlobo lwelensi:
Guqula i-lens yombala: tshintsha i-lens yombala unokulungelelanisa ukuhanjiswa ngokutshintsha umbala, wenze iliso lomntu livumelane nokutshintsha kwendalo, ukunciphisa ukudinwa okubonakalayo, ukukhusela iliso.
I-lens ephezulu ye-refractive index: I-index ephezulu ye-refractive index, i-lens encinci.
Iilensi eziqhubela phambili: Ziqhelanisa nazo zonke iimeko kunye nemigama
Ilensi yeglasi:
Iyakwazi ukumelana nokukrweleka kunezinye iilensi, kodwa inzima noko.
Ilensi yepolymer:
Ikhaphukhaphu kuneelensi zeglasi, ukuchasana kwempembelelo akulula ukwaphula, kodwa ukuqina kuphantsi, kulula ukukrwempa.
Iilensi zePC:
Igama lemichiza yePC yipolycarbonate, enokuqina okuqinileyo, eyaziwa ngokuba yi "space piece", "universe piece", "lens yokhuseleko", akukho lula ukwaphula.Zinobunzima obusisiqingatha kuphela njengeelensi zeresin zesintu, kwaye ubukhulu becala zisetyenziswa kwiilensi ezinombono omfutshane zabantwana okanye iimaski zamehlo kwiimbaleki.
Isibane esiluhlaza:
Uphononongo lufumene ukuba ukukhanya okuluhlaza kunokubangela umonakalo ongapheliyo kwi-retina, kubangele ukubola kwe-macular.Ngoku ukukhanya okuluhlaza kuninzi kwimithombo yokukhanya eyenziweyo.I-Anti blue light lens inokukhusela amehlo, inciphise umonakalo owenziwe yikhompyuter kunye nomthombo wokukhanya we-LED.
Ipolarization:
Iimpawu zokukhanya kwe-polarized ngokuqhelekileyo kukuphelisa ukukhanya okubonakalayo kunye nokukhanya okuthe saa, ukuvala ukukhanya okunamandla, ukwahlula ukukhanya okuyingozi kwe-ultraviolet, impembelelo ebonakalayo icacile, ukuchasana kwempembelelo, ukuchasana nokuqala.
Ukwaleka ilensi:
Inokunciphisa ukukhanya okubonakalayo kwendawo ye-lens, yenza into ecacileyo, ukunciphisa ukukhanya okubonakalisiweyo kwesibuko, ukwandisa ukuhanjiswa kokukhanya.
