I-polarized function ye-sunglasses inokuthintela ukukhanya kwelanga, kwaye ngeli xesha, inokukhusela amehlo kwimisebe ye-ultraviolet.Konke oku kubulela kwizinyuko zesinyithi somgubo olungisa i-clutter kwisibane esifanelekileyo njengoko ibetha iliso, ukuze ukukhanya okubetha iliso kuthambe.
Iiglasi zelanga ezipholileyo zinokufunxa imisonto yendawo eyenza imitha yelanga kuba zisebenzisa umgubo wentsimbi ocolekileyo kakhulu (intsimbi, ubhedu, i-nickel, njl. njl.).Enyanisweni, xa ukukhanya kubetha i-lens, kuthatyathwa ngokusekelwe kwinkqubo ebizwa ngokuthi "ukungenelela okutshabalalisayo".Oko kukuthi, xa amaza okukhanya athile (kule meko UV-A, UV-B, kwaye ngamanye amaxesha infrared) edlula kwilensi, ayacima enye nenye ngaphakathi kwilensi, ukuya ngasesweni.I-superimpositions eyenza amaza okukhanya ayenzeki ngengozi: i-crests ye-wave wave idibanisa kunye nemijelo ye-wave ecaleni kwayo, ibangela ukuba barhoxise enye kwenye.Isenzeko sophazamiseko olutshabalalisayo luxhomekeke kwisalathiso selensi yokuphinda iphindeke (inqanaba apho imitha yokukhanya iphuma emoyeni njengoko idlula kwizinto ezahlukeneyo), kunye nakubunzima belensi.
Ngokuqhelekileyo, ubukhulu be-lens abutshintshi kakhulu, ngelixa i-refractive index ye-lens iyahluka ngokwemichiza.
Iiglasi zelanga ezipholileyo zibonelela ngenye indlela yokukhusela amehlo.Ukukhanya okubonakalisiweyo kwendlela ye-asphalt kukukhanya okukhethekileyo kwe-polarized.Umahluko phakathi koku kukhanya kubonakalisiweyo kunye nokukhanya okuvela ngqo elangeni okanye nawuphi na umthombo wokukhanya owenziweyo ngumbandela wocwangco.Ukukhanya kwepolarized kwenziwa ngamaza angcangcazela kwicala elinye, ngelixa ukukhanya okuqhelekileyo kubunjwe ngamaza angcangcazelayo angayi kwicala elinye.Oku kufana neqela labantu elihambahamba liphazamisekile kunye neqela lamajoni ahamba ngesantya esifanayo, esenza inkcaso ecacileyo.Ngokuqhelekileyo, ukukhanya okubonakalisiweyo luhlobo oluthile lokukhanya okucwangcisiweyo.Iilensi zepolarized zisebenza ngokukodwa ekuthinteleni oku kukhanya ngenxa yeempawu zayo zokucoca.Olu hlobo lwelensi ludlula kuphela kumaza agqagqeneyo angcangcazela kwicala elithile, ngokungathi “ikama” ukukhanya.Ngokumalunga nengxaki yokubonakaliswa kwendlela, ukusetyenziswa kwezibuko zelanga ezipholileyo kunokunciphisa ukuhanjiswa kokukhanya, kuba akuvumeli amaza okukhanya angcangcazelayo ahambelana nendlela ukuba adlule kuyo.Ngapha koko, iimolekyuli ezinde zoluhlu lwesihluzi zilungelelaniswe ngokuthe tye kwaye zifunxa ukukhanya okuthe tye.Ngale ndlela, ubuninzi bokukhanya okubonakalisiweyo kupheliswa ngaphandle kokunciphisa ukukhanya okubanzi kwendawo engqongileyo.
Ekugqibeleni, iiglasi zelanga ezinepolarized zineelens eziba mnyama njengoko imitha yelanga ibetha kuzo.Xa ukukhanya kwacima, kwaphinda kwaqaqamba ngakumbi.Oku kunokwenzeka ngenxa yeekristale zesilivere ze-halide emsebenzini.Phantsi kweemeko eziqhelekileyo, igcina ilensi icace ngokugqibeleleyo.Ngaphantsi kokukhanya kwelanga, isilivere kwi-crystal ihlukaniswe, kwaye isilivere yamahhala yenza ama-aggregates amancinci ngaphakathi kwelensi.Ezi ngqamaniso zesilivere zincinci ziyibhloko ezinqamlezileyo ezinqamlezileyo, azikwazi ukuhambisa ukukhanya, kodwa zinokufunxa ukukhanya kuphela, isiphumo kukwenza mnyama ilens.Ngaphantsi kweemeko ezikhanyayo nezimnyama, iikristale ziphinda zihlaziye kwaye ilensi ibuyela kwindawo eqaqambileyo.
