Iiglasi ezikhusela kwimitha ye-ultraviolet zohlulwe zibe ziindidi ezimbini: iiglasi zelanga kunye ne-polarized glasses. Iindondo zelanga ziiglasi ezaziwayo-kakuhle ezaziwayo ezisetyenziselwa ukuthintela ukukhanya kwelanga kunye nemitha yeultraviolet. Ngokuqhelekileyo zimdaka okanye ziluhlaza. Umahluko phakathi kweeglasi ze-polarized kunye nezibuko zelanga, kodwa ebomini bethu Ukongeza kwimisebe yelanga kunye ne-ultraviolet, ukukhanya kunokubangela umonakalo emehlweni, okwenza amehlo ethu akhathele kwaye achaphazele ukucaca kombono. Iilensi zepolarized ziyakwazi ukuhluza ukukhanya kwaye zifezekise ukukhuselwa kwamehlo okwenyani. Iiglasi zepolarized zezona ziqhelekileyo. Umbala ikakhulu ungwevu omnyama.
Okokuqala, into ekufuneka icaciswe kukuba: enyanisweni, ii-polarizers zinokuthi zithathwe njengohlobo lwezibuko zelanga, kodwa ii-polarizers ziluhlu oluphezulu lwezibuko zelanga. Iipolarizers zinemisebenzi ezingenayo iiglasi zelanga eziqhelekileyo. Lo msebenzi kukuba banokuvala ngokufanelekileyo kwaye bahluze zonke iintlobo zezinto ezinobungozi. Ukukhanya kwepolarized okonakalisa iliso. Ukukhanya okubizwa ngokuba yi-polarized light kukukhanya okungabonakaliyo okuveliswayo xa ukukhanya kudlula kwiindlela ezingalinganiyo, indawo yamanzi, njl., ebizwa ngokuba yi-glare. Xa le mitha yokukhanya ikhanyisela ngokuthe ngqo amehlo abantu, iya kubangela ukungonwabi nokudinwa emehlweni, kubenze bangakwazi ukubona ixesha elide, kwaye ukucaca kwezinto abazibonayo ngokucacileyo akwanelanga.
Uthini umahluko phakathi kweendondo zelanga ezipholileyo neziqhelekileyo?
①Umahluko kumgaqo
Iipolarizers zenziwe ngokusekelwe kumgaqo we-polarization wokukhanya. Ukukhanya kwepolarized kukwabizwa ngokuba kukukhanya kwepolarized. Ukukhanya okubonakalayo liza eliguquguqukayo eligama lalo lokungcangcazela lithe ngqo kwicala losasazo. Isalathiso sokungcangcazela kokukhanya kwendalo asiyomfuneko kwinqwelomoya ejonge kwicala losasazo. Ukukhanya kwepolarized, isalathiso sayo sokungcangcazela silinganiselwe kwicala elithile ngexesha elithile. Ebomini, ngaphezu kokukhanya kwelanga kunye nemitha ye-ultraviolet, xa ukukhanya kudlula kwiindlela ezingalinganiyo, indawo yamanzi, njl. Ukwenzeka kokukhanya kuya kubangela ukungahambi kakuhle kwiliso lomntu, kubangele ukukhathala, kwaye kuchaphazele ukucaca kombono. Iindondo zelanga eziqhelekileyo zinokunciphisa kuphela ubunzulu bokukhanya, kodwa azinakukwazi ukukususa ngokufanelekileyo ukubonakaliswa kwemiphezulu eqaqambileyo kunye nokumenyezela macala onke. Ukongeza ekukhuseleni kwimitha ye-ultraviolet kunye nokunciphisa ubukhulu bokukhanya, ii-polarizers zinokucoca ngokufanelekileyo ukukhanya.
Iindondo zelanga, ezikwabizwa ngokuba ziiglasi zelanga. Iiglasi ezinemibala eqhele ukusetyenziswa ukuthintela ukukhanya kwelanga kunye nemitha ye-ultraviolet. Xa abantu beselangeni, ngokuqhelekileyo kufuneka bahlengahlengise ubungakanani babafundi babo ukuze balungelelanise ukukhanya. Xa ukukhanya kokukhanya kudlula amandla okulungelelaniswa kwamehlo omntu, kuya kubangela umonakalo emehlweni abantu. Iindondo zelanga zivala ilitha elingathandekiyo ngelixa zikhusela amehlo akho kwimitha ye-UV. Ngoko ke, kwimisebenzi yangaphandle, ngakumbi ehlotyeni, abantu abaninzi basebenzisa i-visor yelanga ukuvimba ilanga ukunciphisa ukukhathala okubangelwa ukulungiswa kwamehlo okanye umonakalo obangelwa ukuvuselela ukukhanya okunamandla.
②Umahluko kwimathiriyeli
Iiglasi zelanga zelanga eziqhelekileyo kwimarike zenziwe ngeentsinga ezifakwe kwiifilimu ezipholayo. Yahlukile kwiiglasi zelanga ezikhanyayo ngenxa yokuthambile kwayo kunye ne-arc engazinzanga. Emva kokuba i-lens ihlanganiswe kwaye ifakwe kwifreyimu, kunzima ukuba i-lens ihlangabezane nomgangatho we-optical refractive, okukhokelela kumbono ovulekileyo kunye nokukhubazeka. Ngenxa ye-arc bend engazinzanga, i-lens ikhubazekile, ekhokelela ngokuthe ngqo ekucaciseni okungahambi kakuhle kokuhanjiswa kokukhanya, ukuphazamiseka komfanekiso, kunye nokungakwazi ukufezekisa iziphumo eziqhelekileyo zombono. Kwaye umphezulu kulula ukukrwempa nokunxiba. Ayihlali ixesha elide.
Nangona kunjalo, amaqela ahlukeneyo abantu anokukhetha izibuko zelanga ngokokuthanda kwabo kunye nokusetyenziswa okwahlukileyo. Imisebenzi esisiseko yezibuko zelanga kukunciphisa ukukhanya okunamandla, ukubona ngokucacileyo ngaphandle kokuguqulwa, ukukhusela kwimitha ye-ultraviolet, ukuqaphela imibala ngaphandle kokuphazamiseka, kunye nokuchonga ngokuchanekileyo iimpawu zendlela.
③Umahluko kwisicelo
Ngenxa yokuba iiglasi zelanga ezipholileyo zinokuvala i-100% yemitha eyingozi, zisetyenziswa ikakhulu ku:
1. Unyango lwezonyango: Izigulana zotyando lwamehlo zifuna ukhuseleko olujikelezileyo, kwaye izibuko zelanga zepolarized zezona zilungileyo.
2. Imisebenzi yangaphandle: njengokutyibiliza ekhephini, ukuloba, imidlalo yasemanzini, njl. njl., zonke zifuna iiglasi zelanga ezinokuthintela ngokupheleleyo imitha eyingozi ukuphepha ukwenzakala kwamehlo okanye ukudinwa.
3. Kwakhona kufanelekile ukuqhuba, ukuhamba kunye nokunxiba imihla ngemihla.
Ziziphi iingenelo zokunxiba iindondo zelanga ezipholileyo rhoqo?
1. Ukuphucula umbono wasebusuku: Izibuko zokubona ebusuku ezipolarized zinokuphucula ukungena kokukhanya ebusuku, ngaloo ndlela ziphucula umbono womntu onxibileyo ebusuku nakwiindawo ezinokukhanya okuphantsi.
2. Nciphisa ilitha: Iiglasi zokujonga ebusuku ezipolarized zinokunciphisa ilitha, ngakumbi xa uqhuba ebusuku okanye usebenza ebusuku. Bangakwazi ukunciphisa ukukhanya okuveliswe zizibane zezithuthi ezizayo okanye ezinye izibane ezinamandla, ukuphucula induduzo ebonakalayo, kunye nokuqinisekisa ukhuseleko lokuqhuba kwabaqhubi!
3. Ukuphucula ukuchasana kombala: Izibuko zokujonga ebusuku ezipolarized zinokuphucula umahluko phakathi kwento kunye nemvelaphi, ikwenza kube lula kulowo uyinxibileyo ukwahlula iinkcukacha kunye neekhonto zento ekujoliswe kuyo. Ngokukodwa ebusuku, umbono ngokwawo awucacanga, okwenza ukuqhuba kukhuseleke emva kokunxiba. .
4. Khusela amehlo: I-polarized night goggles inokunciphisa ukucaphuka kwamehlo kunye nokudinwa, ngakumbi xa usebenzisa izixhobo zombane ixesha elide okanye usebenza ebusuku, kwaye inokunciphisa ukungathandeki kwamehlo.
Kufuneka kuqatshelwe ukuba ayinguye wonke umntu ofuna ukunxiba izibuko zombono ebusuku. Ngokuqhelekileyo, abaqhubi basebusuku, abasebenzi basebusuku, okanye abantu abahamba kakhulu ebusuku kufuneka banxibe izibuko zombono ebusuku ukuze baphucule umbono wasebusuku kunye nokunciphisa impembelelo ye-glare.
Ukuba ufuna ukwazi ngakumbi malunga nefashoni yeglasi kunye nothethwano lweshishini, nceda undwendwele iwebhusayithi yethu kwaye uqhagamshelane nathi nangaliphi na ixesha.
