Njengoko iinyanga zentwasahlobo nehlobo zihamba, abaninzi bethu bangaphandle bejabulela imozulu. Ngokukodwa ngexesha lasehlobo, abantu banokukhawuleza ukubamba i-sunscreen ukwenzela ukukhusela ulusu lwabo. Nangona kunjalo, akubona sonke sikulungele ukukhusela amehlo ethu.
Izikhuni zekhwalithi eziphezulu kunye nokukhuselwa kwe-ultraviolet zibaluleke kakhulu kuthi sonke. Sonke sinokulimala kwe- UV .
Kodwa ngaba uyayazi ukuba abantu abathile basengozini enkulu yokulimala kwelanga kunezinye?
Abantu Abanobukhulu Bemibala Ekhanyayo
Amehlo ombala okhanyayo aqheleke ngokukhanya. Bafaka umntu kumngcipheko ophezulu kweso sifo esibangelwa ukungabi ne-pigment ekhuselekileyo kwi-retina.
Nangona inqabileyo, i-melanoma ye-iris kunye ne-retina ixhaphake kakhulu kubantu abaneembala ezikhanyayo. Kwakhona, ukuba nebala elikhanyayo likubeka kumngcipheko ophezulu wokuphuhliswa kwesifo se-macular .
Abantu bethatha ii-Photosensitizing Drugs
Ukusetyenziswa kwezilwanyana zezilwanyana kumiselwe ezinye iinkcazo zezokwelapha, kodwa esinye seziphumo zabo zempembelelo kukuba ziyakwenza ukuba umntu aphuculwe. Oku kunokubangela ukuba i-retina ibe nobungozi belanga.
Uphononongo lubonisa ukuba kuphela ama-50 ekhulwini abantu abathatha iifotosisitizingisa iziyobisi baqonda ukuba banokubangela i-photosensitivity. Ngaba wayesazi ukuba nakwezinye izidakamizwa ezifana ne-ibuprofen (Advil) kunye ne-naproxen sodium (Aleve) inokwenza abantu abathile bavelele?
Thetha ugqirha ukuba uya kuthatha la mayeza ngamaxesha amade kwaye ucele ukuba ungayithatha ukuthintelo. Iziyobisi ezibizwa ngokuba yi-photosensitizing ziquka:
- Ulawulo lokuzala kunye ne-estrogen
- I-Phenothiazine (i-anti-malaria)
- Ezinye iintsholongwane ezinjengeTetracycline
- Psoralens ukunyanga i-psoriasis
Abantwana
Amaphesenti angama-80 kuwo wonke umonakalo we-UV esiwufumanayo ebomini bethu kubakho ngaphambi kokuba aneminyaka eyi-18. Njengabantu abadala, sikulungele ukukhumbuza ukubamba izibuko zelanga xa senza imisebenzi engaphandle. Nangona kunjalo, ngamanye amaxesha sikhohlwa ukukhusela amehlo abantwana bethu.
Abantwana bathambekele ekuchitha ixesha elingaphezulu ngaphandle kwabantu abadala. Izifundo mhlawumbi ngolunye usuku zifumanisa ukuba ezinye zezifo zamehlo esizifumanayo xa sikhula ziyakwazi ukunyanzeliswa kwelanga xa sisebantwana.
Kananjalo, ngamanye amaxesha abantwana abazange bavelise ezinye zeepropati ezikhusela umonakalo we-UV kwamehlo nangesikhumba esiye sakhula njengabantu abadala. I-lens yemvelo ngaphakathi kwamehlo ethu ayizange ivelise ezinye zeempawu zayo zokuvimbela i-UV. Umyalezo: khusela amehlo abantwana bakho ngokunciphisa ukukhanya kwelanga kunye nokuthengwa kwelanga eliphezulu.
Abantu Abanobuchopho-Cataract
Izigidi zabantu baseMelika zifumana unyango lwe-cataract unvent year njalo. Utyando lweCataract lwenziwa xa i-lens ngaphakathi kwamehlo ethu ikhanya kwaye ichanekile kwizinga apho ukukhanya kungenakukugxininisa ngokufanelekileyo kwi-retina yethu. Ngaloo ndlela, umbono ubonakalisa kakhulu.
Iimeko zokuguga zivame ukuziswa ngokuguga. Kodwa abantu abatsha banakho ukuhlakulela i-cataract ngenxa yokuthatha amayeza athile, ukuba nezifo ezithile zenkqubo, okanye ukuba neengxelo zentsapho zokuphuhlisa i-cataract.
Xa sine-cataract ukuhlinzwa kwilensi yethu yemvelo isuswe kwaye ithathelwe indawo ngokufakelwa kwe-lens intraocular. Namhlanje, abaninzi abakhiqizi bakha ukukhuselwa kwe-UV kwinqanaba le-intraocular. Nangona kunjalo, ezinye zezimpembelelo ze-intraocular ezangezikhulile zazingenalo ukukhuselwa kwe-UV. Ngenxa yoko, ezi gulane kufuneka zifake isitya esikhulu esinezixhobo kunye nezikhanyiso zokukhanya ze-UV xa zichitha ixesha elangeni.
