Imbali yezibuko zelanga inokulandelwa emva kwe-14th-ngenkulungwane ye-China, apho abagwebi basebenzisa iiglasi ezenziwe nge-quartz enomsi ukuze bafihle iimvakalelo zabo. Kwiminyaka engama-600 kamva, usomashishini uSam Foster waqala wazisa iindondo zelanga zanamhlanje njengoko sizazi namhlanje kwisiXeko saseAtlantiki. Ukususela ngoko, i-Sunglasses Day yenzeka minyaka yonke ngoJuni 27. Iziganeko zonyaka zijolise ekusasazeni ulwazi malunga nokubaluleka kokugqoka izibuko zelanga zokukhusela i-ultraviolet.
Kutheni ukukhuselwa kwelanga kuyimfuneko kwaye kubalulekile kubomi bemihla ngemihla?
Imitha ye-UV inokwenzakalisa amehlo akho. Ukuba sesichengeni kunokubangela ukuba ube norhatyazo kwiminyaka eyi-8-10 ngaphambili kunesiqhelo. Iseshoni enye nje ende elangeni inokubangela ukucaphuka okubuhlungu kakhulu kwi-corneas yakho. Kukho iinzuzo ezininzi kwiilensi ezinokhuseleko lwe-UV lwe-100% kunokuba ucinga.

1.Ukukhuselwa kwimitha ye-UVA kunye ne-UVB
2.Ukunciphisa ilitha
3.Ukukhululeka kuxinzelelo lwamehlo
I-4.Uncedo ekukhuseleni ukuchithwa kwe-macular, i-cataracts kunye nezinye izifo zamehlo

Ndingazi njani ukuba iiglasi zelanga zinokhuselo lwe-UV? Ngelishwa, akukho lula ukuxelela ukuba iiglasi zakho zelanga zineelensi zokhuselo lwe-UV ngokuzijonga nje.

• Qwalasela indlela ophila ngayo kunye nezinto ozenzayo xa usenza isigqibo sokuba ufuna iiglasi zelanga ezipholileyo, okanye i-photochromic lens okanye ezinye iimpawu zelensi.
• Yazi ukuba i-lens tint emnyama ayiniki ukhuseleko oluthe kratya kwi-UV
