Ilensi yokukhanya eluhlaza okwesibhakabhaka, i-lens edayiwe, ilensi eshintsha umbala, ilensi ehlukanisiwe, ilensi yelanga...... Ilensi emakethe inezinhlobonhlobo eziningi, izinhlobonhlobo, izinto ezibonakalayo kanye nokusebenza kuyahluka, khetha ilensi evumelana nawe ukuze uvumele abantu abaningi benze kube nzima. .Lawa ma-lens anamuphi umsebenzi?Imaphi amaqembu asebenza kuwo?Kufanele bakhethe kanjani izingane kanye nentsha?
Ukukhanya okuluhlaza okwesibhakabhaka kungakhuthaza ukukhula kwamehlo.Akunconywa ukugqoka izibuko ezikhanyayo eziluhlaza okwesibhakabhaka isikhathi eside.Izibuko ezikhanyayo eziluhlaza okwesibhakabhaka zingamunca noma zivimbe ukukhanya okuluhlaza okwesibhakabhaka kwe-short-wave okubangela i-retinopathy, ukuze kuncishiswe inani lokukhanya okuluhlaza okwesibhakabhaka okungena esweni futhi kuvimbele izifo ze-retina ezibangelwa ukukhanya okuluhlaza okwesibhakabhaka.Iphinde yehlise ukuhlakazeka, ivumele izinto ukuthi zivele ngokucace kakhudlwana ku-retina futhi inciphise ubunzima bamehlo.
Kodwa izingilazi ezivimba okuluhlaza okwesibhakabhaka zizodwa azikwazi ukuvimbela i-myopia, futhi ukugqolozela esibukweni isikhathi eside nakho kungabangela ukukhathala.Ngaphezu kwalokho, ukukhanya okuluhlaza okwesibhakabhaka kudlala indima ebalulekile futhi enhle ekuthuthukiseni ama-eyeball ezingane, futhi inani elithile lokuchayeka kokukhanya okuluhlaza okwesibhakabhaka liyadingeka ukuze kugqugquzelwe ukuthuthukiswa kwamehlo ezingane kanye nentsha.
Akunconywa ukuthi izingane kanye nentsha igqoke izibuko ezinemibala endlini.Zombili izibuko ezishintsha umbala nezibuko ezinemibala zingabizwa ngokuthi "izibuko zelanga ezinamadigri," okuyimikhiqizo evamile yezibuko ze-myopia.Kumele kuqashelwe ukuthi ama-lens anebala anezinga elithile, ngakho-ke amafreyimu amakhulu kakhulu akufanele akhethwe.Amafreyimu amakhulu kakhulu ngeke nje abangele imiphetho yelensi ewugqinsi kanye namabala angalingani, kodwa futhi abangele ukungakhululeki kowagqokile.
Ngaphezu kwalokho, amalensi anamabala anganciphisa inani eliphelele lokukhanya okungena esweni, okuthinta ukudluliswa kwelensi.Lapho i-lens iba mnyama, izinto zangaphandle ziba mnyama.Ngakho-ke, kungcono ukuthi ungagqoki izibuko ezingcolile endlini, futhi kuyadingeka ukukhetha ama-lens anemibala emnyama yokugqoka kwangaphandle.
Amalensi ashintsha umbala afaneleka kakhulu kubantu abaneziqu eziphansi futhi awekho umehluko omkhulu phakathi kwamehlo amabili.Amalensi amaningi ashintsha umbala ancike ekukhanyeni kokukhanya kwe-ultraviolet ukulamula inqubo yokushintsha umbala.Ngaphandle, amalensi azivumelanisa ngokuzenzakalelayo nezinguquko ze-uv, ukusuka kumalensi akhanyayo ngokushesha ukuya kumalensi amnyama;Ngaphakathi, amandla emisebe ye-Uv ayancipha futhi amalensi abuyela ebumnyameni aye obala.Uma izinga le-myopia likhulu kakhulu, ilensi incane phakathi nendawo, iwugqinsi emaphethelweni, ikhanya phakathi futhi imnyama nxazonke zombala.Umehluko wedigri yamehlo amabili mkhulu kakhulu, cishe izingcezu ezimbili zokujula kombala zingase zehluke, zithinte umuhle.Ngaphezu kwalokho, izibuko ezishintsha umbala ezisetshenziswe isikhathi eside, umbala wangemuva uzoba sobala kakhulu, othinta ukubukeka, ngakho-ke udinga ukushintshwa njalo eminyakeni emibili.
Izibuko ze-polarized nezibuko zifanele imisebenzi yangaphandle njengokushayela, ukudoba kanye nokushushuluza.I-polarizing lens yengeza ungqimba lwesihlungi e-polarizing, ingahlunga ukukhanya okukhazimulayo okukhazimulayo nokukhanya okuhlakazekile, inomsebenzi wokunciphisa ukuxhopha, ingenza buthaka ngokuphumelelayo ukukhanya okunamandla, yenze umkhakha wokubona ucace kakhudlwana.I-sunglass iso "sunscreen", ingakwazi ukumunca noma i-reflex ukukhanya okuningi, ukunciphisa ukukhanya okungena esweni, ukunciphisa umuzwa ongakhululekile weso, umphumela obaluleke kakhulu ukuvimbela imisebe ye-ultraviolet, ukusiza iso ukunciphisa ukwenzeka kwezifo.
