Ehlobo elishisayo, ingabe ukhathazwa ukukhanya okukhazimulayo okwenza ungakwazi ukuvula amehlo akho?Lapho siya eholidini ngaselwandle noma eqhweni eqhweni, sonke sizwa ukukhanya kunamandla futhi kuyabenyezela, futhi sidinga izibuko zelanga ukuze sivikele izibuko zethu.Kanjalo naweizibuko zelangaakunjalo?
Lapho sithenga izibuko zelanga, kufanele sibheke ukuthi umbala wento uyashintsha yini lapho sifaka izibuko, ukuthi amarobhothi acacile yini, nokuthi umklamo wohlaka uyasifanele yini, ukuthi kuba nesiyezi ngemva kokugqoka, futhi siyeke. ukugqoka ngokushesha uma kukhona ukungakhululeki.Ngokuvamile, izibuko zelanga ezivamile zinamandla okuvimbela ukukhanya okuqinile nokuhlunga imisebe ye-ultraviolet.Kubantu abanezidingo eziphansi, izibuko zelanga ezijwayelekile zingasetshenziswa.Kodwa-ke, abanye abantu abanezidingo eziphakeme zekhwalithi yokubukwa bazokhetha izibuko ze-polarized.
Ziyini izibuko ze-polarized?Ngokusho kwesimiso sokukhanya kwe-polarization, singakhipha ngokuphumelelayo futhi sihlunge ukukhanya okuhlakazekile emgqeni, ukuze ukukhanya kufakwe emfanekisweni weso obonakalayo kusukela ku-axis yokudlulisa ukukhanya yethrekhi efanele, ukuze insimu umbono ucacile futhi wemvelo, njengesimiso sezimpumputhe, okwenza ngokwemvelo indawo ibukeke ithambile futhi ingakhanyi..Izibuko zelanga ezipholileibe nomthelela wemisebe ye-anti-ultraviolet, engakwazi ukuhlukanisa ngokuphumelelayo imisebe yelanga eyingozi.
Isendlalelo sokuqala siwungqimba ohlukanisayo, olumunca ngempumelelo ukuxhopha okubonisiwe okuhambisana ne-eksisi yokudlulisa ukukhanya.Izendlalelo zesibili nezesithathu ziyizingqimba ezimunca i-ultraviolet.Inika amandla amalensi amhlophe ukuthi amunce ama-99% emisebe ye-UV.Ukuze i-lamella akulula ukugqoka.Izendlalelo zesine nesesihlanu ziyizingqimba zokuqinisa ukumelana nomthelela.Inikeza ukuqina okuhle, ukumelana nomthelela, futhi ivikela amehlo ekulimaleni.Izendlalelo zesithupha nesikhombisa ziqiniswa, ukuze i-lamellae ingabi lula ukugqoka.Izibuko ezijwayelekile ze-polarized emakethe zenziwe ngefilimu ye-fiber sandwiched polarizing.Ihlukile ezingilazini zeglasi ezikhanyayo, ngenxa yokuthungwa kwayo okuthambile kanye ne-arc engazinzile, ngemva kokuba i-lens ihlanganiswe kuhlaka, i-lens inzima ukuhlangabezana nezinga le-optical refractive, futhi isithombe esibukwayo sikhululekile futhi sikhubazekile.Ngenxa yokungazinzi kwe-arc kanye nokuguqulwa kwe-lens, kuholela ngokuqondile ekucaciseni okungalungile kwesithombe sokudlulisa ukukhanya nokuhlanekezela kwesithombe, esingakwazi ukufeza imiphumela evamile yombono.Futhi indawo engaphezulu kulula ukunwaya, ukugqokwa futhi ayihlali isikhathi eside.Ngakho-ke, lapho uthenga izibuko zelanga ezinemibala egqamile, kuhle kakhulu ukuqinisekisa ukuthi amalensi angakwazi ukuvimba ngokuphumelelayo ngaphezu kuka-99% wemisebe ye-ultraviolet (kuhlanganise ne-ultraviolet A kanye ne-ultraviolet B) futhi abe nazo zombili izici ze-polarized ukuze kuqedwe ukubenyezela (i-glare ibhekisela ekukhanyeni okunamandla okuvela ama-engeli athile emehlweni. kwenza kube nzima ukubona izinto okwesikhashana).
Ukulimala kwemisebe ye-ultraviolet emzimbeni womuntu kuyakhula.Uma isikhathi eside sokuchayeka elangeni, sikhula umonakalo omkhulu wemisebe ye-ultraviolet.Ngakho-ke, kufanele sigqoke izibuko zelanga njalo ukuze sinciphise ukunqwabelana kwemisebe ye-ultraviolet emehlweni.
Mina Umbonoikhumbuza ukuthi lapho ukhethaizibuko zelanga, ungacabangi ukuthi uma i-lens imnyama, inamandla umphumela we-anti-ultraviolet.Ngokuphambene nalokho, umbala omnyama, umfundi uzoba mkhulu.Ngaphandle kwama-lens aphephile e-anti-ultraviolet, amehlo azovezwa emisebeni ye-ultraviolet eyengeziwe, futhi umonakalo uzoba mkhulu kakhulu.Ukuze ugweme ukulimala kwamehlo okubangelwa imisebe ye-ultraviolet, yebo, kuyadingeka ukunciphisa ukuchayeka elangeni elinamandla, ikakhulukazi phakathi kuka-10:00 ekuseni no-2:00 ntambama, lapho ilanga likhanya ngokuqondile phezu komhlaba, kanye namandla Imisebe ye-ultraviolet iphezulu kakhulu.Ikakhulukazi leyo misebe ye-ultraviolet evezwa kukhonkolo, iqhwa, ibhishi noma amanzi iyona enamandla kakhulu futhi ibangela umonakalo omkhulu emehlweni, kodwa iyona enganakwa kalula.Ngakho-ke, uma uzohlala isikhathi eside kulezi zindawo, khumbula ukugqoka izibuko zelanga ezifanele ze-polarized.
