"Ipolarized? Yintoni i-polarized?Iiglasi zelanga ezipholileyo?"
Imozulu iya ishushu
Lixesha lokuba ukhuphe imitha ye-ultraviolet kwakhona
Namhlanje, sonke makhe sifunde malunga nokuba zeziphi iiglasi zelanga ezipholileyo?
Zintoni iiiiglasi zelanga ezipholileyo?
Iiglasi zelanga zinokwahlulwa zibe zizibuko zelanga ezipholileyo kunye neeglasi eziqhelekileyo ezisekelwe kumsebenzi wazo.
Iiglasi zelanga ezipholileyo: Iilensi zinokukuthintela ngokufanelekileyo ukukhanya kwelanga kunye nemitha ye-ultraviolet. Ngaphezulu koko, banomgca wefilimu we-polarizing onokuvala ukukhanya ukusuka kwicala elithile, ngaloo ndlela ufezekise umphumo wokuthintela ukukhanya.
Iindondo zelanga eziqhelekileyo: Iilensi ubukhulu becala zifakwe tinted, zinciphisa ukuhanjiswa kokukhanya ukuvala ukukhanya kwelanga kunye nemitha yeultraviolet ngaphandle kokuthintela ilitha.
Yintoni umgaqo weiiglasi zelanga ezipholileyo?
Iilensi ze-polarized zenziwe ngokusekelwe kumgaqo we-polarization yokukhanya. Ukongeza ekuthinteleni imitha ye-ultraviolet kunye nokunciphisa ukukhanya kokukhanya, banokuphinda bahluze i-glare. Oku kuvumela ukukhanya kuphela ukusuka kwicala elithile ukuba kudlule kwi-axis ye-lens kwaye ungene emehlweni ukwenza umfanekiso obonakalayo, ngokufanelekileyo ukucinezela ukuphazamiseka okuvela kwimithombo eyahlukeneyo yokukhanya yangaphandle kunye nokuthintela ukukhanya kwelanga ekukhanyeni, okwenza umbono ucace.
Ngokwemigaqo ye-layman: Umsebenzi we-polarized we-lens ufana nokufakela iimfama zamehlo, ukuvumela ukukhanya okukhethekileyo kuphela ukuba kungene kunye nokunciphisa ukuphazamiseka okuvela kwimithombo yokukhanya esasaziweyo.
Yintoni umahluko phakathiiiglasi zelanga ezipholileyokwaye eqhelekileyoiindondo zelangangembonakalo?
Akukho mahluko ucacileyo, kodwa ukuzinxiba kuvakala kuhluke kakhulu. Zama ukufumana ihlabathi elitsha elibonakalayo.
Kweziphi iimeko ezifanelekileyo ukunxiba iiglasi zelanga ezipholileyo?
Imisebenzi yamanzi (ukungayekeleli ngexesha leeyure zomsebenzi)
Ukuloba (hayi ukufuya iintlanzi)
Ukuqhuba (hayi ngesantya esiphezulu)
Ukudlala igalufa (kunye nokudlala intenetya, i-badminton, okanye nayiphi na imidlalo yebhola)
Ukutyibiliza, ukukhempisha, ukunyuka amatye, ukukhwela intaba
Xa ufuna ukufihla izangqa ezimnyama ngenxa yokungabikho kokulala
Ngexesha leenkqubo zamazinyo njengokuzaliswa, ukutsalwa kwezinyo, okanye ukucocwa (kunokunciphisa uloyiko lwamazinyo)
Zisenokusetyenziswa nakwiindawo zonyango kwizifo zamehlo kunye notyando
Ngaba abantu abane-myopia banokunxiba iindondo zelanga ezipholileyo?
Ewe. Kubantu abane-myopic, kuyimfuneko ukukhetha izibuko zelanga ezinokufakelwa iilensi zemithi. Kule mihla, ezinye iiglasi zelanga zinokufakelwa iilensi ezichazwe ngugqirha, kodwa kusekho izithintelo ezininzi ngexesha lokufakwa kwenkqubo.
Indlela yokukhetha esebenzayo ngokweneneiiglasi zelanga ezipholileyo?
(1) Jonga ireyithi yepolarization
Izinga le-polarization yiparameter ephambili yokuvavanya umsebenzi we-polarizing. Ngokuqhelekileyo, okukhona uphezulu umlinganiselo wepolarization, kokukhona ikwazi ukomelela kwelensi ukuvala ilitha, ukukhanya okubonakalayo, nokunye ukukhanya okuthe saa; izinga lepolarization yeelensi ezigqwesileyo ezipholileyo zinokugqitha kuma-99%.
(2) Qonda iteknoloji ye-polarizing yelensi
Inkqubo yokucinezela isangweji yesiqhelo inokubangela iidigri ezingachanekanga kunye neelensi ezishinyeneyo. Inkqubo entsha yokudibanisa, "i-piece-piece integration," ichaneke ngakumbi kwaye ihlala ihlala njalo, ayinakwenzeka ukuba ivelise iipateni zomnyama, kwaye yenza i-lens ibe lula kwaye ibe yincinci.
(3) Khetha iiglasi zelanga ezicatshuliweyo ezinemiphezulu yelensi egqunyiweyo
Inkqubo yokwaleka kumphezulu we-lens yenza iilensi ze-polarized zivelele. Uninzi lwabavelisi beelensi abazinxibi iindondo zabo zelanga, nto leyo ebangela ukuba bangakwazi ukumelana namanzi, ioli nothuli; eneneni, abavelisi sele benobugcisa bokugquma obugqwesileyo obunokuthi bufakwe kwiiglasi zelanga ezipholileyo ukwenza iilensi zisebenziseke ngakumbi kwaye zomelele.
(4) Impembelelo yokukhusela i-ultraviolet
Musa ukulibala, iiglasi zelanga ezipholileyo ziseziiglasi zelanga; banempembelelo eyongezelelweyo ye-polarizing. Ke, iimfuno ezisisiseko zeendondo zelanga nazo ziyasebenza kubo. Iiglasi zelanga ezigqwesileyo kufuneka zifikelele kwi-UV400, nto leyo ethetha ukuba akukho ultraviolet.
