Ukulala echibini lokubhukuda, ukwakha izinqaba zesihlabathi ogwini lolwandle, ukuphonsa idiski endizayo epaki — lezi yizinto ezivamile “zokuzijabulisa elangeni”. Kodwa ngakho konke lokho kujabula onakho, ingabe awuboni izingozi zokuchayeka elangeni?
Lezi yizona eziphezulu4izimo zamehlo ezingabangelwa ukulimala kwelanga — kanye nezinketho zakho zokwelashwa.
1. Ukuguga
Ukuchayeka kwi-ultraviolet (UV) kubangela u-80% wezimpawu ezibonakalayo zokuguga. Imisebe ye-UV iyingozi esikhumbeni sakho. SUkufiphala ngenxa yelanga kungabangela izinyawo ze-crow futhi kujulise imibimbi. Ukugqoka izibuko zelanga ezivikelayo ezenzelwe ukuvimba imisebe ye-UV kusiza ekunciphiseni umonakalo owengeziwe esikhumbeni esizungezile amehlo kanye nazo zonke izakhiwo zamehlo.
Abathengi kufanele bafune ukuvikelwa kwelensi ye-ultraviolet (UV) okuyi-UV400 noma ngaphezulu. Lesi silinganiso sisho ukuthi ama-99.9% emisebe ye-UV eyingozi avinjiwe yilensi.
Izingubo zelanga ze-UV zizovimbela ukulimala kwelanga esikhumbeni esibucayi esizungezile iso futhi zinciphise amathuba okuba nomdlavuza wesikhumba.
2. Ukushiswa yilanga yi-cornea
I-cornea iyisimbozo sangaphandle esicacile seso futhi ingabhekwa “njengesikhumba” seso lakho. Njengoba nje isikhumba singashiswa yilanga, ne-cornea nayo ingashiswa.
Ukushiswa yilanga kwe-cornea kubizwa ngokuthi i-photokeratitis. Amanye amagama avamile e-photokeratitis yi-welder's flash, i-snow blindness kanye ne-arc eye. Lokhu ukuvuvukala okubuhlungu kwe-cornea okubangelwa ukuvezwa kwemisebe ye-UV engahlungiwe.
Njengoba kunjalo ngezimo eziningi zamehlo ezihlobene nelanga, ukuvimbela kuhilela ukusebenzisa izingubo zelanga ezifanele ezivikela i-UV.
3. Ama-cataract
Ubuwazi ukuthi ukuchayeka kwe-UV okungahlungiwe kungabangela noma kusheshise ukukhula kwe-cataract?
Ama-cataract ayi-clouding yelensi esweni engathinta umbono. Nakuba lesi simo samehlo sivame ukuhlotshaniswa nokuguga, unganciphisa ingozi yakho yokuthola ama-cataract ngokugqoka izibuko zelanga ezifanele ezivimba i-UV.
4Ukuwohloka kwe-macular
Umthelela wemisebe ye-ultraviolet ekuthuthukisweni kokuwohloka kwe-macular awuqondakali ngokugcwele.
Ukuwohloka kwe-macular kuhilela ukuphazamiseka kwe-macula, indawo ephakathi ye-retina, ebangela ukubona okucacile. Ezinye izifundo zisola ukuthi ukuwohloka kwe-macular okuhlobene nokuguga kungabhebhethekiswa ukuchayeka elangeni.
Ukuhlolwa kwamehlo okuphelele kanye nezingubo zokuvikela ilanga kungavimbela ukuqhubeka kwalesi simo.
Kungenzeka yini ukubuyisela emuva umonakalo welanga?
Cishe zonke lezi zimo zamehlo ezihlobene nelanga zingelashwa ngandlela thile, kuncishiswe imiphumela emibi uma kungenzeki ukubuyisela emuva inqubo ngokuphelele.
Kungcono ukuzivikela elangeni futhi uvimbele umonakalo ngaphambi kokuba uqale. Indlela engcono kakhulu ongakwenza ngayo lokho ukugqoka isivikelo selanga esivikela amanzi, esimbozwe ububanzi kanye ne-SPF engama-30 noma ngaphezulu, esivimba i-UVizibuko.
