Njengoko imozulu ifudumala, ungazifumana uchitha ixesha elingakumbi ngaphandle. Ukuze ukhusele wena nosapho lwakho kwimozulu, kufuneka unxibe iiglasi zelanga!
Ukuvezwa kwe-UV kunye neMpilo yamehlo
Ilanga lilona mthombo uphambili wemitha ye-Ultraviolet (UV), enokubangela umonakalo emehlweni akho. Ilanga likhupha iintlobo ezi-3 zemitha ye-UV: i-UVA, i-UVB kunye ne-UVC. I-UVC ifunxwa ngumoya woMhlaba; i-UVB ivalekile kancinci; imitha ye-UVA ayihluzwa kwaye ngenxa yoko inokubangela owona monakalo mkhulu emehlweni akho. Nangona kukho iintlobo ngeentlobo zezibuko zelanga, ayizizo zonke iiglasi zelanga ezibonelela ngokhuseleko lwe-UV - kubalulekile ukukhetha iilensi ezibonelela ngokhuseleko lwe-UVA kunye ne-UVB xa uthenga iiglasi zelanga. Iiglasi zelanga zinceda ukuthintela ukuvezwa lilanga elijikeleze amehlo okunokukhokelela kumhlaza wolusu, i-cataract kunye nemibimbi. Iiglasi zelanga zikwabonakalisiwe njengokhuseleko olukhuselekileyo lokubona xa uqhuba kwaye zibonelela ngempilo-ntle iyonke kunye nokhuseleko lwe-UV emehlweni akho ngaphandle.
Ukukhetha iiglasi zelanga ezifanelekileyo
Nangona isitayile kunye nentuthuzelo zidlala indima enkulu ekukhetheni iiglasi zelanga ezifanelekileyo, iilensi ezifanelekileyo nazo zinokwenza umahluko omkhulu.
- Inombalailensi: Imitha ye-UV ikhona unyaka wonke, ingakumbi kwiinyanga zasehlotyeni. Ukunxiba iiglasi zelanga ezibonelela ngokhuseleko lwe-UV oluyi-100% yenye yeendlela ezilula zokunciphisa iingozi ezininzi zempilo yamehlo. Kodwa nceda uqaphele ukuba iilensi ezimnyama aziboneleli ngokuzenzekelayo ngokhuseleko olungakumbi. Khangela ukhuseleko lwe-UVA/UVB oluyi-100% xa uthenga iiglasi zelanga.
- Ilensi epholisiweyo:Iilensi ezahlukeneyo zingaba luncedo kwimisebenzi eyahlukeneyo. Iiglasi zelanga ezinemibala eqaqambileyo azinakukukhusela kuphela kwimitha ye-UV, kodwa zikwanceda ekunciphiseni ukukhanya kunye nokuqaqamba kwemiphezulu efana namanzi. Ngoko ke iiglasi zelanga ezimibala eqaqambileyo zithandwa kakhulu xa ukhwela isikhephe, ukuloba, ukukhwela ibhayisekile, ukudlala igalufa, ukuqhuba kunye neminye imisebenzi yangaphandle.
- I-Mirror Coating ifumaneka kwi-tinted kunye ne-Polarized lens:Iilensi ezinezibuko zibonelela ngokhuseleko lwe-UV kunye nokukhanya okukhanyayo kunye nemibala yesibuko yefashoni.
Ukukhuselwa lilanga kubalulekile unyaka wonke kwaye umonakalo we-UV uyanda ebomini bakho. Ukunxiba iiglasi zelanga yonke imihla xa uphuma emnyango yindlela entle nelula yokuxhasa impilo yamehlo akho.
