Njengoko amaqondo obushushu enyuka, abantu abaninzi baqala ukunxiba iiglasi zelanga xa bephuma. Kodwa ngaba iiglasi zelanga zakho ziyawakhusela amehlo akho? Enyanisweni, ayinguye wonke umntu owaziyo ukuba ukukhetha iiglasi zelanga yisayensi. Iiglasi zelanga ezikhethwe kakubi zinokubangela i-glaucoma.Ngoko ke wIintlobo zeeglasi zelanga zeminqwazi zilungele ihlobo? Nangona isitayile kunye nentuthuzelo zidlala indima enkulu ekukhetheni iiglasi zelanga ezifanelekileyo, iilensi ezifanelekileyo nazo zinokwenza umahluko omkhulu.
Iilensi ezahlukeneyo zokukhanya zibonelela ngamanqanaba ahlukeneyo okhuseleko, ngoko ke ungakhetha ilensi efanelekileyo ngokweemfuno zakho.
1. Iilensi ezinombala
Ngexesha lokuveliswa, izinto ezisetyenziswa ngamakhemikhali zongezwa ukunika iilensi umbala, nto leyo evumela ukuba zifunxe ukukhanya kwemitha ethile yokukhanya. Olu lolona hlobo lwelensi luqhelekileyo kwiiglasi zelanga ezimiselweyo. Kodwa nceda uqaphele ukuba iilensi ezimnyama aziboneleli ngokuzenzekelayo ngokhuseleko olungakumbi. Khangela ukhuseleko lwe-100% lwe-UVA/UVB xa uthenga iiglasi zelanga.
2. Iilensi zePhotochromic
Iilensi ze-photochromic, ezaziwa ngokuba “ziilensi ezibona ukukhanya”, ziqulethe iikhemikhali ze-silver halide. Ezi lensi zicacileyo, ezingenambala, ziba mnyama zibe ziilensi ezinombala xa zibekwe ekukhanyeni okunamandla ukuze zikhuseleke emehlweni, nto leyo ezenza zifaneleke ukusetyenziswa ngaphakathi nangaphandle.Ngoko ke pIilensi ze-hotochromic zisebenza njengeeglasi ezimiselwe ngugqirha kunye neeglasi zelanga, zibonelela ngesisombululo esilula, esipheleleyo esikhusela amehlo kwimitha yelanga ye-UV kwaye sinciphise ukukhanya kunye nokukhanya okuluhlaza okwesibhakabhaka.
3. Iilensi ezivuthulukileyo
Iilensi ezi-polarized ziilensi ezikhethekileyo ezigqunywe ngefilimu ekhethekileyo ejonge ngokuthe nkqo evumela ukukhanya okuhamba kwicala elinye ukuba kudlule. Zihluza ukukhanya okubukhali, okufana nokukhanya okuboniswa lilanga emanzini, emhlabeni okanye ekhephini, zithambise ukukhanya ukuze ubone kakuhle kwaye zinciphise ukukhanya ukuze kubonakale into ngokucacileyo. Iilensi ezi-polarized zinokunciphisa ukukhanya okuvela kwiindlela ze-asphalt, iindonga zeglasi, imiphezulu yamanzi kunye nekhephu, zisuse ukukhanya kunye nokukhanya, ziphucule umahluko wemibala kwindawo entle, kwaye zinike ukumelana okuhle nokukhanya okunamandla.
Iiglasi zelanga azizange zenzelwe imfashini kuphela; ukuzinxiba yindlela esebenzayo yokuzikhuselayakhoamehlo ngenxa yomonakalo we-UV. YUngafumana iinkcukacha ezithe vetshe malunga ne-Universe sunlens ngu https://www.universeoptical.com/sun-lens/
