Umsebenzi we-polarized wezibuko zelanga ungavimba ukukhanya kwelanga, futhi ngalesi sikhathi, ungavikela amehlo emisebeni ye-ultraviolet.Konke kungenxa yezikhwezi zokuhlunga zensimbi ezilungisa imfuhlumfuhlu ekukhanyeni okulungile njengoba ishaya iso, ukuze ukukhanya okushaya iso kuthambe.
Izibuko zelanga ezipholile zingamunca ngokukhetha amabhande endawo akha imisebe yelanga ngoba zisebenzisa izimpushana zensimbi ezinhle kakhulu (insimbi, ithusi, i-nickel, njll.).Eqinisweni, lapho ukukhanya kushaya ilensi, kukhishwa ngokusekelwe kwinqubo ebizwa ngokuthi "ukungenelela okulimazayo".Okusho ukuthi, lapho amaza okukhanya athile (kulokhu i-UV-A, UV-B, futhi ngezinye izikhathi i-infrared) edlula kulensi, ayakhanselana ngaphakathi kwelensi, ngasesweni.Ama-superimpositions akha amagagasi okukhanya awekho ngengozi: ama-crests egagasi elilodwa ahlangana nemikhombe yamagagasi eduze kwawo, okubangela ukuba akhansele ngaphandle.Ukwenzeka kokuphazanyiswa okulimazayo kuncike kunkomba yelensi yokuhlehla (izinga lapho imisebe yokukhanya ichezuka khona emoyeni njengoba idlula ezintweni ezihlukene), kanye nasebugqileni belensi.
Ngokuvamile, ubukhulu be-lens abushintshi kakhulu, kuyilapho inkomba ye-refractive ye-lens ihlukahluka kuye ngokwakhiwa kwamakhemikhali.
Izibuko zelanga ezipholile zinikeza enye indlela yokuvikela amehlo.Ukukhanya okubonisiwe komgwaqo wetiyela kuwukukhanya okukhethekile kwe-polarized.Umehluko phakathi kwalokhu kukhanya okuveziwe kanye nokukhanya okuvela ngqo elangeni nanoma yimuphi umthombo wokukhanya owenziwe yindaba yokuhleleka.Ukukhanya kwe-polarized kunamagagasi adlidliza aye ohlangothini olulodwa, kuyilapho ukukhanya okuvamile kunamagagasi adlidlizela lapho angayi khona.Lokhu kufana neqeqebana labantu elihambahamba ngokungahlelekile kanye neqembu lamasosha elimasha ngesivinini esifanayo, lakha ukuphikisa okucacile.Ngokuvamile, ukukhanya okubonisiwe kuwuhlobo lokukhanya okuhlelekile.Ama-lens ane-polarized asebenza kahle kakhulu ekuvimbeni lokhu kukhanya ngenxa yezindawo zokuhlunga.Lolu hlobo lwamalensi ludlula kuphela kumaza ahlukanisiwe adlidliza aye ohlangothini oluthile, njengokungathi “ikama” ukukhanya.Ngokuphathelene nenkinga yokukhanya komgwaqo, ukusetshenziswa kwezibuko zelanga ezine-polarized kunganciphisa ukudluliswa kokukhanya, ngoba akuvumeli amaza okukhanya adlidliza ahambisana nomgwaqo ukuze adlule.Eqinisweni, ama-molecule amade ongqimba lwesihlungi aqondiswe ngokuvundlile futhi amunca ukukhanya okuvundlile.Ngale ndlela, ukukhanya okuningi okubonisiwe kuyaqedwa ngaphandle kokunciphisa ukukhanya okuphelele kwendawo ezungezile.
Ekugcineni, izibuko zelanga ezine-polarized zinamalensi aba mnyama njengoba kushaya imisebe yelanga.Lapho ukukhanya kufiphala, kwaphinde kwakhanya.Lokhu kungenzeka ngenxa yamakristalu esiliva we-halide emsebenzini.Ngaphansi kwezimo ezijwayelekile, igcina ilensi ikhanye ngokuphelele.Ngaphansi kokushiswa kokukhanya kwelanga, isiliva ku-crystal ihlukaniswa, futhi isiliva samahhala sakha ama-aggregate amancane ngaphakathi kwelensi.Lezi zinhlamvu ezincane zesiliva zingamabhulokhi angavamile we-criss-cross, azikwazi ukudlulisa ukukhanya, kodwa zingakwazi ukumunca ukukhanya kuphela, umphumela uwukwenza i-lens ibe mnyama.Ngaphansi kwezimo ezikhanyayo nezimnyama, amakristalu avuselelwa futhi ilensi ibuyela esimweni esikhanyayo.
