Ehlotyeni, ngaba ukhathazwa kukukhanya okuqaqambileyo okwenza ungakwazi ukuvula amehlo akho?Xa sisiya ekhefini ngaselwandle okanye sityibiliza ekhephini, sonke sivakalelwa kukuba ukukhanya kunamandla yaye kuqaqambile, yaye sifuna iindondo zelanga ukuze sikhusele iindondo zethu.Nawe ngokunjaloiindondo zelangakunene?
Xa sithenga iindondo zelanga, sifanele sijonge enoba umbala wento uyatshintsha kusini na xa sinxiba iindondo, enoba iirobhothi zicacile, yaye indlela eyenziwe ngayo ifreyimu isifanelekele, kukho isiyezi emva kokunxiba, size siyeke. enxibe ngoko nangoko ukuba kukho nakuphi na ukungakhululeki.Ngokubanzi, iiglasi zelanga eziqhelekileyo zinamandla okuthintela ukukhanya okuqinileyo kunye nokucoca imisebe ye-ultraviolet.Kubantu abaneemfuno ezisezantsi, iiglasi zelanga eziqhelekileyo zingasetyenziswa.Nangona kunjalo, abanye abantu abaneemfuno eziphezulu zomgangatho wokubonwayo baya kukhetha iiglasi zepolarized.
Ziziphi iiglasi ezipholileyo?Ngokomgaqo we-polarization wokukhanya, inokungabandakanyi ngokufanelekileyo kwaye ihluze ukukhanya okuthe saa kwi-beam, ukuze ukukhanya kufakwe kumfanekiso obonakalayo weso ukusuka kwi-axis yokuhambisa ukukhanya yendlela efanelekileyo, ukwenzela ukuba intsimi umbono ucacile kwaye wendalo, kanye njengomgaqo weemfama, okwenza ngokwemvelo indawo ibonakale ithambile kwaye ingabonakali..Iiglasi zelanga ezipholileyoibe nefuthe lemitha ye-anti-ultraviolet, enokwahlula ngokufanelekileyo imitha yelanga eyingozi.
Uluhlu lokuqala luluhlu lwe-polarizing, oluthatha ngokufanelekileyo i-glare ebonakalisiweyo ye-perpendicular kwi-axis yokuhambisa ukukhanya.Uluhlu lwesibini nolwesithathu luluhlu olufunxa i-ultraviolet.Ivumela iilensi ezimhlophe ukuba zifunxe i-99% yemitha ye-UV.Ukuze i-lamella ingabi lula ukuyinxiba.Imigangatho yesine neyesihlanu yimpande-resistance reinforcement layers.Ibonelela ngokuqina okulungileyo, ukuxhathisa impembelelo, kwaye ikhusela amehlo ekwenzakaleni.Uluhlu lwesithandathu kunye nolwesixhenxe luqiniswa, ukwenzela ukuba i-lamellae ingabi lula ukuyinxiba.Iindondo zelanga eziqhelekileyo kwimarike zenziwe ngefiber sandwiched polarizing film.Ihluke kwiglasi yeglasi ye-optical polarized sunglasses, ngenxa yokwakheka kwayo okuthambileyo kunye ne-arc engazinzanga, emva kokuba i-lens ihlanganiswe kwisakhelo, i-lens inzima ukuhlangabezana nomgangatho we-optical refractive, kwaye umfanekiso obonakalayo ukhululekile kwaye ukhubazekile.Ngenxa yokungazinzi kwe-arc kunye ne-deformation ye-lens, ikhokelela ngokuthe ngqo ekucaciseni okungahambi kakuhle komfanekiso ohambisa ukukhanya kunye nokuphazamiseka komfanekiso, ongenakukwazi ukufikelela kwimiphumo eqhelekileyo yombono.Kwaye umphezulu kulula ukukrazulwa, ugqoke kwaye ungapheli.Ngoko ke, xa kuthengwa izibuko zelanga ze-polarized, kungcono ukuqinisekisa ukuba iilensi zinokuvala ngokufanelekileyo ngaphezu kwe-99% yemitha ye-ultraviolet (kubandakanywa ne-ultraviolet A kunye ne-ultraviolet B) kwaye ibe neempawu zombini ze-polarized ukuphelisa ukukhanya (i-glare ibhekisela ekukhanyeni okunamandla okubonakaliswa iiengile ezithile emehlweni.yenza kubenzima ukubona izinto okwethutyana).
Umonakalo wemitha ye-ultraviolet kumzimba womntu uyakhula.Okukhona ixesha lokuba sesichengeni elangeni lide, kokukhona umonakalo omkhulu kwimitha yeultraviolet.Ngoko ke, kufuneka sinxibe iindondo zelanga rhoqo ukuze sinciphise ukuqokelelana kwemitha ye-ultraviolet emehlweni.
ndingumbonoikhumbuza ukuba xa ukhethaiindondo zelanga, ungacingi ukuba i-lens emnyama, inamandla ngakumbi i-anti-ultraviolet effect.Ngokuchasene noko, umbala ubumnyama, umfundi uya kuba mkhulu.Ngaphandle kwe-anti-ultraviolet lens ekhuselekileyo, amehlo aya kubonakala kwimitha ye-ultraviolet engaphezulu, kwaye umonakalo uya kuba nzima kakhulu.Ukunqanda umonakalo wamehlo obangelwa yimitha ye-ultraviolet, ewe, kuyimfuneko ukunciphisa ukukhanya kwelanga okunamandla, ngakumbi phakathi kwe-10: 00 am kunye ne-2: 00pm, xa ilanga likhanya ngokuthe ngqo phezu komhlaba, kunye nobukhulu belanga. Imitha ye-ultraviolet yeyona iphezulu.Ngokukodwa loo mitha ye-ultraviolet ebonakaliswe kwikhonkrithi, ikhephu, ulwandle okanye amanzi iyona nto inamandla kwaye ibangela umonakalo omkhulu emehlweni, kodwa yizona zilula kakhulu zingahoywa.Ke ngoko, ukuba uza kusebenza kwezi ndawo ixesha elide, khumbula ukunxiba iiglasi zelanga ezifanelekileyo.
