Umlando wezibuko zelanga ungalandelelwa emuva ku-14th-century China, lapho amajaji ayesebenzisa izibuko ezenziwe nge-quartz eshunqayo ukuze afihle imizwa yawo. Eminyakeni engu-600 kamuva, usomabhizinisi uSam Foster wethula okokuqala izibuko zelanga zesimanje njengoba sizazi namuhla e-Atlantic City. Kusukela lapho, uSuku Lwezibuko Zelanga lwenzeka minyaka yonke ngo-June 27. Imicimbi yaminyaka yonke ihlose ukusabalalisa ukuqwashisa ngokubaluleka kokugqoka izibuko zelanga ukuze kuvikelwe i-ultraviolet.
Kungani ukuvikelwa kwelanga kudingekile futhi kubalulekile ekuphileni kwansuku zonke?
Imisebe ye-UV ingalimaza amehlo akho. Ukuchayeka kungadala ukuthi uthole ungwengwezi eminyakeni eyi-8-10 ngaphambi kwesikhathi esijwayelekile. Isikhathi esisodwa nje eside elangeni singabangela ukucasuka okubuhlungu kwama-corneas akho. Kunezinzuzo eziningi kumalensi anokuvikelwa kwe-UV okungu-100% kunalokho okubonayo. Ngokuzayo lapho ufaka ama-shades akho owathandayo, ungasebenzisa lokhu okulandelayo:
1.Ukuvikelwa emisebeni ye-UVA ne-UVB
2.Ukunciphisa ukukhanya
3.Ukukhululeka ekucindezelekeni kwamehlo
I-4.Usizo ekuvimbeleni ukuwohloka kwe-macular, i-cataract nezinye izifo zamehlo
5.Ukuvikela umdlavuza wesikhumba endaweni eseduze kwamehlo
6.Umthunzi ovela elangeni elikhanyayo, elingavimbela ubuhlungu bekhanda
7.Ukuvikela ezintweni zangaphandle njengokungcola, udoti nomoya
8.Ukuvimbela imibimbi
Ngingabona kanjani ukuthi izibuko zelanga zinokuvikeleka kwe-UV? Ngeshwa, akulula ukubona ukuthi izibuko zakho zelanga zinamalensi okuvikela i-UV ngokuwabuka nje. Futhi awukwazi ukuhlukanisa inani lokuvikela ngokusekelwe kumbala welensi, njengoba ama-lens tints awahlangene nokuvikelwa kwe-UV. Nawa amathiphu ambalwa lapho ukhetha izingubo zamehlo ezivikela ilanga:
• Bheka ilebula emkhiqizweni ophathekayo noma encazelweni yawo yephakheji eqinisekisa ukuvikelwa okungu-100% kwe-UVA-UVB noma i-UV 400.
• Cabangela indlela yakho yokuphila kanye nemisebenzi lapho unquma ukuthi ufuna izibuko zelanga ezine-polarized, noma ilensi ye-photochromic noma ezinye izici zamalensi.
• Yazi ukuthi umbala omnyama welensi awunikezi ngempela isivikelo se-UV
