Iingcebiso zokusebenzisa iindondo zelanga

I-1) Kwiimeko eziqhelekileyo, i-8-40% yokukhanya ingangena kwiiglasi zelanga.Uninzi lwabantu lukhetha i-15-25% yezibuko zelanga.Ngaphandle, iiglasi ezininzi eziguqula umbala zikolu luhlu, kodwa ukukhanya kokukhanya kweeglasi ezivela kubavelisi abahlukeneyo kuyahluka.Imibala emnyama yokutshintsha iiglasi inokungena kwi-12% (ngaphandle) ukuya kwi-75% (yangaphakathi) ukukhanya.Iimpawu ezinemibala ekhaphukhaphu zinokungena kwi-35% (ngaphandle) ukuya kwi-85% (yangaphakathi) ukukhanya.Ukuze ufumane iiglasi ezinobunzulu obufanelekileyo bombala kunye ne-shading, abasebenzisi kufuneka bazame iimpawu ezininzi.

I-2) Nangona iiglasi eziguqula umbala zifanelekile ukusetyenziswa kwansuku zonke, azifanelekanga kwimisebenzi yezemidlalo kwiindawo ze-glare, ezifana nokuhamba ngesikebhe okanye ukushushuluza.Idigri ye-shading kunye nobunzulu bombala we-sunglasses ayinakusetyenziswa njengomlinganiselo wokhuseleko lwe-UV.Iglasi, iplastiki okanye iilensi zepolycarbonate zongeze iikhemikhali ezifunxa ukukhanya kweultraviolet.Ngokuqhelekileyo azinambala, kwaye ne-lens ecacileyo inokuthintela ukukhanya kwe-ultraviolet emva konyango.

3) I-chromaticity kunye ne-shading yeelensi zihluke.Izibuko zelanga ezinokukhanya ukuya kwi-moderate shading zifanelekile ukugqoka imihla ngemihla.Kwiimeko ezikhanyayo ezikhanyayo okanye imidlalo yangaphandle, kuyacetyiswa ukuba ukhethe izibuko zelanga ezinomthunzi onamandla.

I-4) Idigri ye-shading ye-gradient dichroic lens iyancipha ngokulandelelana ukusuka phezulu ukuya phezulu okanye ukusuka phezulu ukuya phakathi.Inokukhusela amehlo ekukhanyeni xa abantu bejonge esibhakabhakeni, kwaye kwangaxeshanye babone ngokucacileyo imbonakalo engezantsi.Umphezulu kunye nomzantsi welensi yegradient ephindwe kabini imnyama ngombala, kwaye umbala ophakathi ukhaphukhaphu.Ziyakwazi ukubonakalisa ngokufanelekileyo ukukhanya kwamanzi okanye ikhephu.Sincoma ukuba ungasebenzisi izibuko zelanga xa uqhuba, kuba ziya kuphazamisa ideshibhodi.
