"I-Polarized? Yintoni e-polarized?Iiglasi zelanga ezipholisiweyo?"
Imozulu iya ishushu
Lifikile ixesha lokuphinda silahle imisebe ye-ultraviolet
Namhlanje, masifunde ukuba ziintoni iiglasi zelanga ezimibalabala?
Zintoni iiiiglasi zelanga ezipholisiweyo?
Iiglasi zelanga zinokwahlulwa zibe ziiglasi zelanga ezimibalabala kunye neeglasi zelanga eziqhelekileyo ngokusekelwe kumsebenzi wazo.
Iiglasi zelanga ezivuthululweyo: Iilensi zinokuthintela ngempumelelo ukukhanya kwelanga kunye nemisebe ye-ultraviolet. Ngaphezu koko, zinomgangatho wefilimu evuthululweyo onokuthintela ukukhanya kwicala elithile, ngaloo ndlela zifezekisa isiphumo sokuthintela ukukhanya okukhanyayo.
Iiglasi zelanga eziqhelekileyo: Iilensi zinombala kakhulu, nto leyo enciphisa ukuhanjiswa kokukhanya ukuze kuthintelwe ukukhanya kwelanga kunye nemisebe ye-ultraviolet ngaphandle kokuthintela ukukhanya.
Yintoni umgaqo weiiglasi zelanga ezipholisiweyo?
Iilensi ezi-polarized zenziwe ngokusekelwe kumgaqo we-light polarization. Ukongeza ekuthinteleni imisebe ye-ultraviolet kunye nokunciphisa amandla okukhanya, zinokuhluza ukukhanya okukhanyayo. Oku kuvumela ukukhanya okuvela kwicala elithile kuphela ukuba kudlule kwi-axis yelensi kwaye kungene emehlweni ukuze kwenziwe umfanekiso obonakalayo, kuthintela ngempumelelo ukuphazamiseka okuvela kwimithombo eyahlukeneyo yokukhanya kwangaphandle kunye nokuthintela ukukhanya kwelanga ngqo ukuba kukhanye, okwenza umbono ucace ngakumbi.
Ngokwendlela eqhelekileyo: Umsebenzi weelensi odibanisayo ufana nokufaka iiblinds zamehlo, okuvumela kuphela ukukhanya okukhululekileyo ukuba kungene kwaye kuncitshiswe ukuphazamiseka okuvela kwimithombo yokukhanya esasazekileyo.
Zithini umahluko phakathiiiglasi zelanga ezipholisiweyokunye nokuqhelekileyoiiglasi zelangangembonakalo?
Akukho mahluko ucacileyo, kodwa ukuzinxiba kuvakala kwahlukile kakhulu. Zama ukuva ihlabathi elitsha elibonakalayo.
Kukweziphi iimeko apho kufanelekile ukunxiba iiglasi zelanga ezinemibala eqaqambileyo?
Imisebenzi yamanzi (ukungaphumli ngexesha leeofisi)
Ukuloba (hayi ukulima iintlanzi)
Ukuqhuba (hayi ukuqhuba ngesantya esiphezulu)
Ukudlala igalufa (kunye nokudlala itenisi, i-badminton, okanye nayiphi na imidlalo yebhola)
Ukuskiya, ukukhempisha, ukunyuka amatye, ukuhamba intaba
Xa kufuneka ufihle izangqa ezimnyama ngenxa yokungalali ngokwaneleyo
Ngexesha leenkqubo zamazinyo ezifana nokuzalisa amazinyo, ukukhupha amazinyo, okanye ukucoca (kunokunciphisa uloyiko lwamazinyo)
Zingasetyenziswa nakwiindawo zonyango kwizifo zamehlo kunye notyando
Ngaba abantu abane-myopia bangakwazi ukunxiba iiglasi zelanga ezinombala oqaqambileyo?
Ewe. Kubantu abanengxaki yokubona izinto ezingabonakaliyo, kuyimfuneko ukukhetha iiglasi zelanga ezinokufakelwa iilensi zikagqirha. Kule mihla, ezinye iiglasi zelanga zinokufakelwa iilensi zikagqirha, kodwa kusekho imiqathango emininzi ngexesha lenkqubo yokufakela.
Indlela yokukhetha okusebenzayo ngokweneneiiglasi zelanga ezipholisiweyo?
(1) Jonga izinga lokwahlukana
Izinga le-polarization yeyona parameter iphambili yokuvavanya umsebenzi we-polarizing. Ngokubanzi, xa izinga le-polarization liphezulu, kokukhona amandla e-lens okuvimba ukukhanya okukhanyayo, ukukhanya okubonakalayo, kunye nokunye ukukhanya okusasazekayo kunamandla; izinga le-polarization leelensi ezibalaseleyo ze-polarized linokudlula i-99%.
(2) Qonda itekhnoloji ye-polarizing yelensi
Inkqubo yesiqhelo yokucinezela isandwich inokubangela amazinga angachanekanga kunye neelensi ezijiyileyo. Inkqubo entsha yokudibanisa, "ukuhlanganiswa kwento enye," ichanekile kwaye ihlala ixesha elide, akunakwenzeka ukuba ivelise iipateni zombala werainbow, kwaye yenza ilensi ibe lula kwaye incinci.
(3) Khetha iiglasi zelanga ezimibalabala ezinee-lens ezigqunywe ngemibala
Inkqubo yokugquma kumphezulu welensi yenza iilensi ezigqumayo zibonakale. Uninzi lwabavelisi beelensi abazigqumi iiglasi zabo zelanga ezigqumayo, nto leyo ebangela ukuba zingabi namanzi, ioyile, kunye nothuli; eneneni, abavelisi sele benazo iindlela zobugcisa zokugquma ezingasetyenziswa kwiiglasi zelanga ezigqumayo ukuze iilensi zibe lula ukuzisebenzisa kwaye zihlale ixesha elide.
(4) Isiphumo sokukhusela i-Ultraviolet
Ungalibali ukuba, iiglasi zelanga ezinemibala eqaqambileyo ziseziglasi zelanga; zinefuthe elongezelelekileyo lemibala eqaqambileyo. Ngoko ke, iimfuno ezisisiseko zeeglasi zelanga nazo ziyasebenza kuzo. Iiglasi zelanga ezimibala eqaqambileyo nazo kufuneka zifikelele kwi-UV400, oko kuthetha ukuba azidlulisi i-ultraviolet.
