Ukubuka konke

Abaningi bethu abakwazi ukubuka ilanga elikhanyayo isikhathi eside. Amehlo ethu abucayi aqala ukusha, bese sicwayiza ngokwemvelo bese sibheka eceleni ukugwema ukungaphatheki kahle.

Ngesikhathi ukusitheka kwelanga - lapho inyanga ivimba okwesikhashana ukukhanya elangeni - ukubuka ilanga kuba lula kakhulu. Kepha lokho akusho ukuthi kufanele ngabe uyakwenza. Ukugqolozela ngqo elangeni ngisho noma nje kungadala ukulimala kwamehlo okukhulu.

Funda ukuze ufunde ngezingozi zokugqolozela ilanga nokuthi yini okufanele uyenze uma ucabanga ukuthi usuvele ulimele amehlo akho.

Kwenzekani lapho ubuka ilanga isikhathi eside?

Lapho ukukhanya kwe-ultraviolet (UV) okuvela elangeni kungena esweni, kugxilwe ngaphakathi kwelensi yeso kuye kwi-retina engemuva kweso. I-retina iyizicubu ezizwela ukukhanya ezingaphakathi kweso.

Uma isimungene kwi-retina, imisebe ye-UV iholela ekwakhekeni kwama-radicals amahhala. Lawa ma-radicals amahhala aqala ukongeza izicubu ezizungezile. Ekugcineni babhubhisa ama-photoreceptor enduku nama-cone ku-retina. Umonakalo we-oxidative ubizwa ngokuthi yi-solar or photic retinopathy.

Ukulimala kungenzeka ngemizuzwana nje embalwa yokubuka ngqo elangeni.

Ziyini izimpawu zokulimala kweso ekubhekeni ilanga?

Ngaphandle kwazo zonke izixwayiso, abanye abantu basengabuka iso elangeni lapho kusitheka ilanga. Lokho abantu abaningi abangaqapheli ukuthi ngeke ubuzwe ubuhlungu beso ngenkathi umonakalo wenzeka.

Ezimweni eziningi, mhlawumbe ngeke uze uqaphele izimpawu noma ushintsho lombono khona lapho, noma. Kungathatha amahora afinyelela kwangu-12 ukuthi uqale ube nezimpawu. Izimpawu ze-retinopathy yelanga zingenzeka esweni elilodwa nje, kepha izimo eziningi zenzeka kuwo womabili amehlo ngasikhathi sinye.

Ezimweni ezimnene ze-photic retinopathy, ungathola lezi zimpawu ezilandelayo:

• amehlo anamanzi
• ukungakhululeki ukubheka amalambu akhanyayo
• ubuhlungu beso
• ikhanda

Lezi zimpawu ezilandelayo zingavela ezimweni ezimbi kakhulu:

• ukungaboni kahle
• ukuncipha kombono
• ubunzima bokuqonda ubujamo
• umbono osontekile
• indawo engaboni noma izindawo eziningi eziyimpumputhe maphakathi nombono wakho
• ukulimala kwamehlo unomphela

Ungabona nini udokotela wamehlo

Uma uhlangabezana nanoma yiziphi izimpawu ze-retinopathy yelanga amahora amaningana noma usuku ngemuva kokugqolozela ilanga, bheka udokotela wamehlo wakho ukuze uhlolwe.

Uma udokotela wakho wamehlo ekholelwa ukuthi une-retinopathy yelanga, cishe uzoba nokuhlolwa okwengeziwe okuqediwe ukuhlola ngokuphelele noma yimuphi umonakalo ku-retina.

Ngesikhathi sokuqokwa kwakho, udokotela wamehlo wakho angasebenzisa inqubo eyodwa noma eziningi zokucabanga ukubheka amehlo akho, kufaka phakathi:

• i-fundus autofluorescence (FAF)
• i-fluorescein angiography (FA)
• i-multifocal electroretinography (mfERG)
• i-optical coherence tomography (i-OCT)

Ukwelapha ukulimala kwamehlo

Akukho ukwelashwa okujwayelekile kwe-solar retinopathy. Ukubuyiselwa ikakhulu kumayelana nokulinda kuphume. Izimpawu cishe zizothuthuka ngokuhamba kwesikhathi, kepha kungathatha noma yikuphi ukusuka enyangeni eyodwa kuya onyakeni ukuze ululame ngokuphelele. Abanye abantu bangaze baphinde bathole umbono wabo ngokuphelele.

Izithasiselo ze-antioxidants zingasiza ngesikhathi sokululama, kepha ukusetshenziswa kwama-antioxidants ekwelashweni akufundwanga.

Ukuthola kabusha kuzoncika ekutheni umonakalo weso ungakanani. Ngenkathi abanye abantu abane-retinopathy yelanga bengenza ukululama okugcwele ngokuhamba kwesikhathi, umonakalo omkhulu kusuka ku-retinopathy yelanga kungadala ukulahlekelwa unomphela kombono.

Ukuvimbela ukulimala emehlweni akho

Njengoba ingekho imishanguzo esebenzayo yokuguqula ukubuyela emuva kwelanga nge-solar, ukuvimbela kubaluleke kakhulu.

Ukuvimbela nsuku zonke

Ngezinsuku ezishisayo, qiniseka ukuthi ugqoka izibuko zelanga nesigqoko esinomphetho obanzi. Abantu ababamba iqhaza emidlalweni yamanzi, njengokuntweza emanzini, kufanele futhi bagqoke ukuvikelwa kwamehlo okuvimba amaphesenti ayi-100 emisebe ye-UV emanzini. Kubalulekile ukuthi izibuko zakho zelanga zivikele amehlo akho ekukhanyeni kwe-UVA ne-UVB.

Izingane zisengozini enkulu yokuba ne-retinopathy yelanga. Amehlo amancane angadlulisela ukukhanya okwengeziwe ku-retina. Izingane nazo zingase zingayiqondi ngokugcwele imiphumela yokugqolozela ilanga isikhathi eside kakhulu. Uma unezingane, qiniseka ukuthi ukwenza kucace ukuthi akufanele zibheke ngqo elangeni. Bakhuthaze ukuthi bagqoke isigqoko nezibuko zelanga uma bengaphandle.

Ngesikhathi ukusitheka kwelanga

Kungaba okulingayo, kepha akufanele neze ubheke ilanga ngqo ngesikhathi sokufiphala kwelanga ngaphandle kokuvikelwa kweso okufanele. I-American Astronomical Society inikezela ngohlu olude lwezibuko ezimboziwe zokusitheka kwelanga kanye nezibukeli eziphathwa ngelanga.

Uma wazi ukuthi ukusitheka kwelanga kuzobukeka endaweni yangakini, cabanga ukubamba izingilazi zokusitheka kwelanga ngokushesha okukhulu. Njengoba usuku lokusitheka kwelanga lusondela, izingilazi zingase zibe nzima ukuzithola. Izibuko ze-Eclipse zamahhala zivame ukutholakala kumtapo wezincwadi wangakini ngaphambi komcimbi wokusitheka kwelanga.

Ungalokothi ubuke ilanga ngokusebenzisa izibonakude, izibuko zelanga ezivamile, isibonakude noma ilensi yekhamera. Ukubuka ilanga ngesibonakude noma izibonakude, ezikhulisa imisebe yelanga, kukhonjisiwe ukuthi kudala umonakalo omkhulu.

Akunconyelwa futhi ukuthi uzame ukubuka ukusitheka kwelanga ngemodi ye-“selfie” yekhamera ye-smartphone yakho. Kungenzeka kakhulu ukuthi ubheke ilanga ngephutha ngenkathi uhlela ikhamera yakho. Ungalimaza futhi ifoni yakho.

Gwema ukusebenzisa izidakamizwa zokuzijabulisa ngesikhathi somcimbi wokusitheka kwelanga. Abantu abangaphansi kwethonya lemithi ye-hallucinogenic, njengaye, baziwa ukuthi bazithola sebemangele ngenxa yokusitheka kwelanga futhi bengakwazi ukubheka eceleni.

Okubalulekile

Ngenkathi ilanga likondla izimpilo zethu, kubaluleke kakhulu ukuthi ungalibheki ngqo, noma ngabe ukusitheka okuphelele noma okuyingxenye. Ngenkathi ungahle ungabuzwa ubuhlungu noma uzwe noma yimuphi umonakalo njengoba ubheka ilanga, ingozi yokulimala kwamehlo akho iphezulu.
