Njengoba ihlobo lisondela, ukugqoka izibuko zelanga ezisemfashinini sekuphenduke umkhuba.Uma sihamba emgwaqweni, sizobona abantu abagqoke izibuko zelanga.Kodwa-ke, kubangane abane-myopia nezidingo ezikhethekile zamehlo, badinga ukugqoka kokubili izibuko ze-myopia nezibuko.Ngakho-ke, isixazululo esilula futhi esiphephile ukwenza ngokwezifiso izibuko ezinemibala ezihambisana neziqu zakho, ukuze inkinga izoxazululwa.
Amalensi e-Photochromic, owaziwa nangokuthi "amalensi ahlakaniphile akhanyayo", asetshenziselwa ukuvikela amehlo nokunciphisa ukukhathala okubukwayo ngokunciphisa ukukhanya okunamandla, imisebe ye-UV nokukhanya okuluhlaza okwesibhakabhaka ekungeneni kwamehlo.Izinto ezizwela ukukhanya (njenge-silver halide) zengezwa ku-lens futhi zivezwe ekukhanyeni okubonakalayo kwe-ultraviolet negagasi elifushane, umbala uba mnyama futhi ukudluliswa kokukhanya kuyehla.Ezindaweni zasendlini noma ezimnyama, ukukhanya kwelensi kuyathuthukiswa, nombala uyafiphala nokukhanya kuyabuyiselwa.I-photochromism yamalensi iyazenzakalela futhi iyabuyiseleka emuva.Amalensi e-Photochromic angakwazi ukulungisa ukudluliswa kokukhanya ngokushintsha umbala welensi, ukuze iso lomuntu likwazi ukujwayela izinguquko ekukhanyeni okuzungezile.
Amalensi Anemibala
Amalensi anemibalabhekisela ekusetshenzisweni kwamanye ama-ejenti ombala phakathi nenqubo yokukhiqiza ilensi ukuze enze amalensi abonakale anombala futhi amunce ubude obuthile bokukhanya.Amalensi anombala avame ukusetshenziswa ezingilazini zelanga.Uma iqhathaniswa namalensi e-resin ajwayelekile, inokumelana okuqinile kwe-UV nokumelana nemisebe.
Amalensi anombala akhula ngokushesha okukhulu kulezi zinsuku.Kunezinhlobonhlobo zemibala yelensi.Lapho kufaneleka, udinga ukufuna izeluleko zodokotela bamehlo ukuze ukhethe umbala ofanele welensi.Ilungele abanye abantu abanezilonda ze-fundus, ukuwohloka kwe-macular, ne-photophobia yeso ngemva kokuhlinzwa kwe-cataract.Abantu abanezifo zamehlo kudingeka bakhethe amalensi afanele umbala wamehlo abo.
Amalensi ane-polarizedamalensi akhiqizwa ngokusekelwe esimisweni sokuhlukanisa ukukhanya, anomsebenzi wokuqeda ukuxhopha, okwenza umbono ucace futhi ube ngokwemvelo.Bangakwazi ukuthuthukisa umbono womshayeli futhi bakhulise injabulo yokushayela.
Umthelela wamalensi e-polarizing ukuhlunga ukuxhopha, okwenza indawo yokubuka icace futhi ibe ngokwemvelo.Ngokufana nesimiso samakhethini angaboni, ukukhanya kulungiswa ukuze kungene esweni ohlangothini olufanayo, ngokwemvelo okwenza indawo ibonakale ithambile futhi ingacwazi.Thuthukisa umbala nokugqama, thuthukisa ukunethezeka nokuphepha kokushayela, vimba ukukhanya okuyingozi, futhi amathuluzi abalulekile abashayeli besikhathi eside nabathanda ukushushuluza.
