Iipolarizers zenziwe ngokomgaqo we-polarization wokukhanya. Siyazi ukuba xa ilanga likhanya endleleni okanye emanzini, liwacaphukisa ngokuthe ngqo amehlo, lenze amehlo azive edayizela, ediniwe, kwaye engakwazi ukubona izinto ixesha elide, ngakumbi xa uqhuba imoto kwaye usenza imisebenzi yangaphandle yokuzonwabisa. , engachaphazeli kuphela umsebenzi wethu kunye neemvakalelo zoLonwabo zinokuchaphazela umbono wethu wezinto kwaye zibangele ingozi. Xa ubonakaliswe kukukhanya kwelanga ixesha elide, kuya kukhokelela ekunciphiseni ngokukhawuleza kombono, okukhokelela kwi-myopia, i-hyperopia, i-astigmatism okanye i-cataracts.
2. Indima ye-polarizer
Ngokufanelekileyo ungabandakanyi kunye nokucoca ukukhanya okuhlakazekileyo kwi-beam, ukwenzela ukuba ukukhanya kufakwe kumfanekiso obonakalayo weso kwi-axis yokuhambisa ukukhanya kwendlela efanelekileyo, kwaye intsimi yombono icacile kwaye yendalo; vala ukukhanya okuyingozi, i-polarize ukukhanya, kwaye ifunxe ngokupheleleyo le mitha eya kubangela ukumenyesa kunye nomonakalo wamehlo. ilitha.
1. Xa uqhuba, ukuba uqhuba kwitrafikhi, awusayi kuphinda ukhathazwe kukukhanya kwelanga kunye nokubonakala okuninzi kwisithuthi esingaphambili.•
2. Xa ukuloba, amaza amanzi akhanya phantsi kokukhanya kwelanga, kodwa awuyi kuziva ukhululekile, kodwa uzive ukhululekile kwaye ude: umboniso uphelile.
3. Xa utyibilika ekhephini, kwibala elikhulu lekhephu, awudingi kugxila kwimbonakalo kunye neminye imigca engaphandle, unokutyibilika kumxholo wentliziyo yakho.
4. Xa kunetha imvula, iimpawu zendlela ezizaliswe yimvula zibonakala ngokucacileyo phambi kwamehlo akho!
5. Xa usekhefini, imitha engaphezulu ye-UV ivalwe ngokufanelekileyo, ikuvumela ukuba ujabulele ixesha lokuphumla ngokupheleleyo.
Iiglasi zelanga zisetyenziselwa ukukhusela ilanga. Abantu bahlala behlengahlengisa ukukhanya okukhanyayo ngokuhlengahlengisa ubungakanani bomfundi elangeni. Xa ukukhanya kokukhanya kudlula amandla okulungelelaniswa kweliso lomntu, kuya kubangela umonakalo kwiliso lomntu. Ngoko ke, kwimisebenzi yangaphandle, ngakumbi ehlobo, kuyimfuneko ukusebenzisa izibuko ze-sunshade ukuvimba ilanga, ukwenzela ukunciphisa ukukhathala okubangelwa ukulungiswa kwamehlo okanye umonakalo obangelwa ukuvuselela ukukhanya okunamandla.
Indima yeilangaiiglasi
1. Umhombiso omhle, ukugubungela iziphene zamehlo, kunye nobuso obuncinci obubonakalayo. Le ithiyori yabekwa phambili nguDade Olsen. Ithiyori yakhe ilula kakhulu. Abasetyhini abathanda ubuhle kunye nokunciphisa baya kuhlala bezenza ngamabomu babonakale bencinci kwaye bencinci. Inkulu izibuko zelanga kwibhulorho yempumlo, ngakumbi Ubuso bakho bubonakala buncinci, budala "ubuso obunqabileyo" obubonakalayo.
2. Thintela imitha ye-ultraviolet ekukhanyeni kwelanga. Imitha yeultraviolet inokonakalisa i<em>cornea neretina, yaye iiglasi zelanga ezikumgangatho ophezulu zinokuyiphelisa ngokupheleleyo imitha ye<em>ultraviolet.
3. Thintela ukukhanya okuqinileyo. Xa iliso lifumana ukukhanya okukhulu kakhulu, ngokwemvelo lidibanisa iris. Yakuba i-iris icutheka ukuya kutsho kumda, abantu kufuneka bakrwaqula, yaye ukuba kusekho ukukhanya okukhulu, njengokukhanya kwelanga okuvela ekhephini, kungonakalisa iretina. Iiglasi zelanga ezikumgangatho ophezulu zinokuhluza ukuya kuthi ga kwi-97% yokukhanya okungena esweni ukunqanda umonakalo.
4. Thintela ukuba sesichengeni kwilitha. Imiphezulu ethile, njengamanzi, ibonakalisa ukukhanya okuninzi. Iziphumo eziqaqambileyo ezibangelwayo zinokuphazamisa umbono okanye zifihle izinto.
5. Ukuphelisa ukukhanya kweefrikhwensi ezithile. Izandi ezithile zokubona luzizi, ngelixa ezinye ziphucula umahluko. Iiglasi zelanga ezingabizi kakhulu zihluza inxalenye yokukhanya, zibangela ukuba iris ivuleke ukuze ifumane ukukhanya okungakumbi kunye nemitha ye-ultraviolet engaphezulu ukungena, inyusa umonakalo owenziwe yimitha ye-ultraviolet kwiretina. Ke ngoko, kukho iiyantlukwano phakathi kweentlobo ezahlukeneyo zeendondo zelanga, kwaye ukukhetha ezona glasi zilungileyo, ezikumgangatho ophezulu kwindawo ethile yokusetyenziswa kuya kukubonelela ngokhuseleko olukhulu.
yintoni imibala yezibuko zelanga ezilungileyo
Okokuqala, iyonke, imibala ye-lens engcono kakhulu yezibuko zelanga zimdaka, zingwevu kwaye ziluhlaza kunye nezinye iilensi ezinombala okhanyayo, ezineziphumo ezibonakalayo ezingcono kunye neziphumo zokukhusela. Ewe kunjalo, ukuba yeyokwenza nje ukwenza okanye ukuthelekisa, unokukhetha imibala eqaqambileyo yelensi ukuqaqambisa owakho umtsalane. Kwaye ziziphi iingenelo kunye nokungonakali kwezibuko zelanga ezinemibala eyahlukeneyo yelensi?
Uthotho lweBrown: Ibonwa njengowona mbala ubalaseleyo welensi kwiimveliso zeglasi zelanga ezimdaka, inokufunxa phantse i-100% yemitha ye-ultraviolet kunye ne-infrared; kunye neethoni ezithambileyo zenza umbono ukhululeke kwaye wenze amehlo angabi lula ukudinwa.
Uluhlu olungwevu: Iyakwazi ukufunxa ngokupheleleyo imitha ye-infrared kunye noninzi lwemitha ye-ultraviolet, kwaye ayizukutshintsha umbala wokuqala wendawo. Imibala ethambileyo, yendalo lukhetho oludumileyo lwelensi.
Uchungechunge oluluhlaza: Njengeeglasi ezingwevu, inokufunxa yonke imitha ye-infrared kunye ne-99% yemitha ye-ultraviolet, kunye ne-cyan kunye nobomvu ekukhanyeni nazo zivaliwe, kodwa ngamanye amaxesha umbala wendawo uya kutshintshwa emva kokudlula kwiilensi eziluhlaza, kodwa ngenxa yokuba uhlaza luzisa ukuphola Ukuziva ukhululekile, ukukhuselwa kwamehlo okulungileyo, ngoko ke lukhetho lokuqala lwabahlobo abaninzi.
Uthotho olumthubi: Iilensi ezityheli zinokufunxa imitha ye-ultraviolet eyi-100% kunye nobuninzi bokukhanya okuluhlaza. Emva kokufunxa ukukhanya okuluhlaza okwesibhakabhaka, indawo oyibonayo iya kucaca ngakumbi, ngoko ke kuqhelekile ukunxiba iilensi ezityheli njengezihluzi xa uzingela kwaye udubula.
Uchungechunge olubomvu: Uluhlu olubomvu lweelensi zelanga lungcono ekuthinteleni ukukhanya okunobude obufutshane, ngelixa ezinye iziphumo zokukhusela zingaphantsi kunezinye iintlobo ezintathu zemibala.
