Imitha ye-ultraviolet inokonakalisa i-cornea kunye ne-retina, kwaye iiglasi zelanga ezikumgangatho ophezulu zinokukuphelisa ngokupheleleyo ukukhanya kwe-ultraviolet.
Xa iliso lifumana ukukhanya okukhulu kakhulu, ngokwemvelo lidibanisa iris.Nje ukuba iris inciphe ukuya kumda wayo, abantu ke kufuneka bancwine.Ukuba kusekho ukukhanya okukhulu kakhulu, okufana nokukhanya kwelanga okuvela kwikhephu, umonakalo kwiretina uya kwenzeka.Iiglasi zelanga ezikumgangatho ophezulu zinokuhluza ukuya kuthi ga kwi-97% yokukhanya okungena emehlweni akho ukunqanda umonakalo.
Iindawo ezithile, ezifana namanzi, zibonisa ukukhanya okukhulu, kwaye iindawo ezikhanyayo ezibangelwayo zinokuphazamisa ukujonga okanye ukufihla izinto.Iindondo zelanga ezikumgangatho ophezulu zinokuluphelisa ngokupheleleyo olu hlobo lwelitha lisebenzisa itekhnoloji yokuphola, esiya kuthi siyigqume kamva.
Izandi ezithile zokubona luzizi, ngelixa ezinye iifrikhwensi zikhulisa umahluko.Khetha umbala ofanelekileyo ukuze iiglasi zakho zelanga zisebenze ngcono kwindawo ethile.
Ukuba iiglasi zelanga aziboneleli ngokhuseleko lwe-UV, ziya kukubeka esichengeni semitha ye-UV engaphezulu.Iiglasi zelanga zexabiso eliphantsi zihluza okunye ukukhanya, okubangela ukuba irises yakho ivuleke ukufumana ukukhanya okungakumbi.Oku kuya kuvumela imitha ye-ultraviolet ngakumbi ukuba ingene, inyusa umonakalo owenziwe yimitha ye-ultraviolet kwiretina.
Ngoko ke, kukho ngokwenene umahluko phakathi kweentlobo ezahlukeneyo zeendondo zelanga.Ukukhetha iiglasi zelanga ezichanekileyo, ezikumgangatho ophezulu kwindawo oyisebenzisayo kuya kukubonelela ngokhuseleko olukhulu.
Ngokwemigangatho yamazwe ngamazwe, iiglasi zelanga zihlelwa njengemveliso yokukhusela amehlo.Umsebenzi ophambili wezibuko zelanga kukuthintela ilitha lokukhanya kwelanga.Noko ke, imigangatho yamazwe ngamazwe iyahlulahlula iindondo zelanga zibe “ziiglasi zefashoni” kunye “neziglasi zenjongo eqhelekileyo.”Iimfuno zomgangatho "kwizibuko zefashoni" kwimigangatho ziphantsi.Ngenxa yokuba ugxininiso oluphambili lwe "izibuko zefashoni" ziyisitayela, umntu onxibayo ubeka ingqalelo kumhlobiso kunomsebenzi wokukhusela.Iimfuno zomgangatho womgangatho "weeglasi zenjongo jikelele zingqongqo, kubandakanya iimfuno zokhuseleko lwe-UV, i-diopter kunye namandla eprism."
