Njengoba sonke sazi, amazwe amaningi abhekene nenkinga enkulu yokuguga kwabantu. Ngokombiko osemthethweni okhishwe yiZizwe Ezihlangene (i-UN), iphesenti labantu asebekhulile (abangaphezu kweminyaka engama-60) lizobe selingaphezu kweminyaka engama-60 ubudala ngo-2050.
Kusukela ezicini zokunakekelwa kwamehlo, yini esingayenzela le ngxenye yabantu?
Siyazi ukuthi ukukhanya kwe-UV akusikho kuphela okuthinta ikhwalithi yokubona. Uma selikhulile kuneminyaka engaphezu kwengu-40, ilensi yeso yemvelo iqala ukushintsha, ingasabonakali ngokuphelele, bese iba phuzi.Igxathu emvakwe gxathuKutholakale ukuthi kukhona okungenziwa ukuvimbela lokhu kulahlekelwa ukucaca ngemijikelezo yokuguga.
Ukukhanya okuphuzi kubonakala kakhulu, futhi lolu hlobo lokukhanya lubangela ukucasuka okucasulayo lapho kungena esweni lomuntu omdala.
Ubuchwepheshe belensi ye-UV+585cut sebuyatholakala ukuze kuncishiswe lokhu kukhanya okucasulayo futhi kuthuthukiswe umehluko wemibala ebomvu neluhlaza okotshani, ikakhulukazi ukuthuthukisa induduzo yokubona kwesiguli.
Ubuchwepheshe be-UV+585cut bunciphisa ukudluliswa kwamaza athile azungeze i-UV585 (ububanzi bokukhanya okuphuzi ku-spectrum) kanye namaza okukhanya okuluhlaza okwesibhakabhaka okwenza ilensi ibe nezici ezinhle kakhulu ekuvinjweni kokukhanya, ukugqama kombala, kanye nokunethezeka.kanye nokubona okucacile. Ifanelekela ukushayela eduze, ezemidlalo, ukuphumula kanye nokusebenzisa amadivayisi edijithali.
Indalo yonkei-optical ikhiqiza ikhwalithi ephezulu yezinhlobo ezahlukene zamalensi akhethekile okusebenza,kufaka phakathiilensi ye-UV585, kanye nemininingwane eyengeziwe iyatholakalahttps://www.universeoptical.com/1-60-uv-585-yellow-cut-lens-product/
