Umphumela wezibuko zelanga

Imisebe ye-ultraviolet ingalimaza i-cornea ne-retina, futhi izibuko zelanga zekhwalithi ephezulu zingakuqeda ngokuphelele ukuchayeka e-ultraviolet.
Lapho iso lithola ukukhanya okukhulu, ngokwemvelo lifinyeza iris.Lapho i-iris isincipha yafinyelela emkhawulweni wayo, abantu-ke kudingeka banciphe.Uma kusenokukhanya okuningi kakhulu, njengokukhanya kwelanga okuvela eqhweni, ukulimala ku-retina kuzokwenzeka.Izibuko zelanga ezisezingeni eliphezulu zingasefa kufika ku-97% wokukhanya okungena emehlweni akho ukuvikela umonakalo.
Izindawo ezithile, njengamanzi, zibonisa amanani amakhulu okukhanya, futhi izindawo ezikhanyayo ezingaba umphumela zingaphazamisa ukubuka noma ukufihla izinto.Izibuko zelanga zekhwalithi ephezulu zingaluqeda ngokuphelele lolu hlobo lokuxhopha zisebenzisa ubuchwepheshe be-polarizing, esizosimboza kamuva.
Amafrikhwensi athile okubona kokufiphalisa ukukhanya, kuyilapho amanye amafrikhwensi ethuthukisa ukugqama.Khetha umbala ofanele ukuze izibuko zakho zelanga zisebenze kangcono endaweni ethile.

Uma izibuko zelanga zingakunikezi isivikelo se-UV, zizokuveza emisebeni ye-UV eyengeziwe.Izibuko zelanga ezishibhile zihlunga okunye ukukhanya, okubangela ukuthi irises yakho ivuleke ukuze zithole ukukhanya okwengeziwe.Lokhu kuzophinde kuvumele imisebe ye-ultraviolet eyengeziwe ukuba ingene, okwandisa umonakalo obangelwa imisebe ye-ultraviolet ku-retina.
Ngakho-ke, kukhona ngempela umehluko phakathi kwezinhlobo ezahlukene zezibuko zelanga.Ukukhetha izibuko zelanga ezilungile, zekhwalithi ephezulu zendawo oyisebenzisayo kuzokunikeza ukuvikeleka okukhulu kakhulu.
Ngokwezindinganiso zamazwe ngamazwe, izibuko zelanga zihlukaniswa njengemikhiqizo yokuvikela iso lomuntu siqu.Umsebenzi oyinhloko wezibuko zelanga ukuvimbela ukuxhopha kokukhanya kwelanga.Nokho, izindinganiso zamazwe ngamazwe zihlukanisa izibuko zelanga zibe “izibuko zemfashini” kanye “nezibuko zenhloso evamile.”Izidingo zekhwalithi "zezibuko zemfashini" emazingeni ziphansi kakhulu.Ngenxa yokuthi ukugcizelela okuyinhloko "kwezibuko zemfashini" kuyisitayela, ogqokile unaka umhlobiso kunomsebenzi wokuzivikela.Izimfuneko zekhwalithi zendinganiso “zezibuko zenhloso evamile ziqinile ngokuqhathaniswa, okuhlanganisa nezimfuneko zokuvikelwa kwe-UV, i-diopter namandla e-prism.”
