Ukulala echibini, ukwakha iinqaba zesanti elunxwemeni, ukuphosa idiski ebhabhayo epakini — le yimisebenzi eqhelekileyo “yolonwabo elangeni”. Kodwa ngalo lonke olo lonwabo unalo, ngaba awuboni iingozi zokuchatshazelwa lilanga?
Ezi zezona ziphezulu4iimeko zamehlo ezinokubangelwa kukulimala lilanga — kunye neendlela onokukhetha kuzo zonyango.
1. Ukwaluphala
Ukuvezwa yi-ultraviolet (UV) kubangela i-80% yeempawu ezibonakalayo zokwaluphala. Imitha ye-UV iyingozi kulusu lwakho. SUkukrazula ngenxa yelanga kunokubangela iinyawo ze-crow kunye nokubindeka okukhulu. Ukunxiba iiglasi zelanga ezikhuselayo ezenzelwe ukuthintela imisebe ye-UV kunceda ukunciphisa umonakalo ongakumbi kulusu olujikeleze amehlo kunye nazo zonke izakhiwo zamehlo.
Abathengi kufuneka bajonge ukhuseleko lwelensi ye-ultraviolet (UV) oluyi-UV400 nangaphezulu. Olu vavanyo luthetha ukuba i-99.9% yemitha ye-UV eyingozi ivalwe yilensi.
I-UV sundresses iya kuthintela umonakalo welanga kulusu oluthambileyo olujikeleze iliso kwaye inciphise amathuba okuba nomhlaza wesikhumba.
2. Ukutshiswa lilanga yi-cornea
I-cornea sisigqubuthelo sangaphandle esicacileyo seliso kwaye singathathwa “njengesikhumba” seliso lakho. Njengokuba ulusu lunokutshiswa lilanga, ne-cornea nayo inokuba njalo.
Ukutsha lilanga kwe-cornea kubizwa ngokuba yi-photokeratitis. Amanye amagama aqhelekileyo e-photokeratitis yi-welder's flash, i-snow blindness kunye ne-arc eye. Oku kukudumba okubuhlungu kwe-cornea okubangelwa kukuvezwa kwimitha ye-UV engacocwanga.
Njengakwimeko ezininzi zamehlo ezinxulumene nelanga, ukuthintela kubandakanya ukusebenzisa iimpahla zelanga ezifanelekileyo ezikhusela i-UV.
3. IiCataracts
Ubusazi na ukuba ukuvezwa yi-UV engahluzwanga kunokubangela okanye kukhawulezise uphuhliso lwe-cataract?
Ii-cataracts zizinto ezifiphalisa ilensi emehlweni ezinokuchaphazela umbono. Nangona le meko yamehlo idla ngokunxulunyaniswa nokwaluphala, unganciphisa umngcipheko wokuba ne-cataracts ngokunxiba iiglasi zelanga ezifanelekileyo ezithintela i-UV.
4Ukuwohloka kwe-macular
Impembelelo yemitha ye-ultraviolet ekuphuhlisweni kwe-macular degeneration ayikaqondwa ngokupheleleyo.
Ukonakala kwe-macular kubandakanya ukuphazamiseka kwe-macula, indawo ephakathi kwi-retina, ebangela ukuba umbono ucace. Ezinye izifundo zicinga ukuba ukonakala kwe-macular okunxulumene nobudala kunokwanda kukukhanya kwelanga.
Ukuhlolwa kwamehlo okupheleleyo kunye neempahla zokukhusela ilanga kunokuthintela ukuqhubeka kwale meko.
Ngaba kunokwenzeka ukubuyisela umva umonakalo owenziwe lilanga?
Phantse zonke ezi meko zamehlo ezinxulumene nelanga zinokunyangwa ngandlela thile, zinciphise iziphumo ebezingalindelekanga ukuba aziyi kuguqula yonke inkqubo.
Kungcono ukuzikhusela elangeni kwaye uthintele umonakalo ngaphambi kokuba uqale. Eyona ndlela ingcono onokuyenza kukufaka i-sunscreen enokumelana namanzi, i-wide spectrum kunye ne-SPF engama-30 nangaphezulu, i-UV-blocking.iiglasi.
