Kukatentha, anthu ambiri amasankha kuvala magalasi oteteza maso awo.Magalasi adzuwa odziwika kwambiri amagawika kukhala tinted ndi polarized.Kaya ndi ogula kapena mabizinesi, magalasi okhala ndi polarized siachilendo.
Tanthauzo La Polarization
Polarization, yomwe imadziwikanso kuti polarized light, imatanthawuza kuwala kowoneka ngati mafunde opingasa, komwe kumayenderana ndi momwe zimafalikira.Mayendedwe a kugwedera kwa kuwala kwachirengedwe ndi kosasinthasintha mu ndege perpendicular kwa malangizo a kufalitsa;kwa kuwala kwa polarized, kugwedezeka kwake kumangopita kumalo enaake panthawi inayake.
Polarization Gulu
Polarization ikhoza kugawidwa m'mitundu itatu: polarization ya mzere, polarization ya elliptical, ndi polarization yozungulira.Nthawi zambiri, zomwe zimatchedwa polarization zimatanthawuza polarization, yomwe imadziwikanso kuti polarization ya ndege.Kugwedezeka kwa mtundu uwu wa mafunde a kuwala kumakonzedwa motsatira njira inayake ndipo kumakhalabe kosasintha.Njira yake yofalitsira mumlengalenga imatsata njira yokhotakhota ya sinusoidal, ndipo mawonekedwe ake pa ndege yolunjika kumayendedwe akufalikira ndi mzere wowongoka.
The ndege kupangidwa ndi kugwedera malangizo a linearly polarized kuwala ndi malangizo kufalitsa amatchedwa ndege kugwedera, ndi ndege perpendicular kugwedera malangizo ndi munali malangizo kufalitsa amatchedwa ndege polarization.Kudutsa kuwala kwachilengedwe kudzera pa polarizer kumatha kutulutsa kuwala kozungulira.
Ntchito ya Polarization
M’moyo watsiku ndi tsiku, pali zinthu zambiri zounikira zomwe zimatulutsa kuwala koipa, makamaka kuwala kwa dzuwa.Kuwala kwa dzuwa kumatulutsa mitundu itatu ya kuwala: kuwala kowoneka, kuwala kwa infrared, ndi kuwala kwa ultraviolet (UV).Mwa izi, kuwala kwa ultraviolet kungayambitse vuto lalikulu pakhungu ndi maso.Kuwala kowoneka kumayambira pa 380 mpaka 780 nanometers, pomwe kuwala kwa ultraviolet kumagawikanso kukhala UVA, UVB, ndi UVC, yokhala ndi mafunde apamwamba kuposa 310nm.UVA, UVB, ndi UVC ndi kunyezimira kovulaza.Kukumana ndi cheza kwa nthawi yayitali kumatha kuwononga thupi.UVB imakhudza kwambiri masomphenya, komanso ndi "kunyezimira" komwe kumadetsa khungu.Makona ambiri a diso amatenga kuwala kwamtundu wa UVB kotero ndikofunikira kutsekereza gwero la kuwalako.
Magalasi a polarizedali ndi ntchito yowunikira polarizing, yomwe imawalola kuti atseke kuwala kovulaza popanda kuwononga kufalikira kwa kuwala kowoneka, potero kuteteza maso.Kuphatikiza pa ntchito yofunikira ya chitetezo cha UV, ma lens opangidwa ndi polarized alinso ndi anti-glare, misewu, ndi ntchito zowunikira pamadzi, kuwapangitsa kukhala oyenera kuyendetsa, kusodza, kuyenda, ndi kuvala tsiku ndi tsiku.
Kupanga Kwa Ma Lens Polarized
M'mawu a anthu wamba,magalasi a polarizedkwa kuyang'ana pafupi ali ndi kapangidwe kamene kamakhala ngati masangweji (opangidwa ndi kutsogolo kwa magalasi adzuwa, wosanjikiza wapakati wa ulusi wa polarized, ndi wosanjikiza wakumbuyo wa magalasi owonera pafupi, zonse zowala pamodzi).Ma lens omwe amagwiritsidwa ntchito kwambiri amakhala ndi index ya refractive ya 1.50 (palinso 1.60, koma ndi okwera mtengo).Magalasi ndi okhuthala komanso olemetsa, ndipo ngati mankhwalawo aposa 600 °, zonse zokongola komanso zotonthoza zidzakhudzidwa kwambiri.Mtengo wa magalasi opangidwa ndi polarized kuti uyang'anire pafupi ndiotalikirapo ndipo zimatengera kukhazikika kwazomwe wopanga amapanga komanso mtundu wake.
Ma lens opangidwa ndi polarized ndi othandiza pakusefa kuwala kwina komwazika (monga magalasi akhungu), koma pali kusiyana kwakukulu muubwino.Magalasi opangidwa ndi polarized osawoneka bwino amatha kuphwanyidwa komanso kusweka, ndipo ambiri samakwaniritsa miyezo ya kuwala.
Zida Za Ma Lens Polarized
Pali mitundu inayi yodziwika bwinomagalasi a polarizedpamsika: magalasi agalasi, ma lens a resin, ma lens a PC, ndi ma lens a TAC.
① Magalasi agalasi
Ngakhale kuti ndi osagwirizana ndi zokanda ndipo ali ndi mawonekedwe abwino a kuwala, kulemera kwawo ndi zovuta zachitetezo zapangitsa kuchepa kwapang'onopang'ono pakugwiritsa ntchito kwawo.
② Magalasi a resin
Ndiosavuta kupendekera, opepuka, komanso osagwira ntchito, kuwapanga kukhala chimodzi mwazinthu zodziwika bwino zamagalasi otchuka.Komabe, ma lens a utomoni amatha kugwedezeka panthawi yowongolera, ndipo amatha kuyikabe ziwopsezo zachitetezo akakhudzidwa kwambiri.
③ Magalasi a TAC
TAC ndi imodzi mwazinthu zowonekera kwambiri zama cell.Magalasi a TAC monga magalasi ali ndi zinthu monga asidi ndi alkali kukana, opepuka, komanso okwera mtengo.Komabe, magalasi a TAC ali ndi kusamva bwino kwa ma abrasion komanso mawonekedwe osakhazikika a kuwala.Ngakhale kuti ali ndi mtengo wotsika, adasiyidwa ndi mitundu yambiri yodziwika yakunja.
④ magalasi a PC
Ndiopepuka, ali ndi ntchito yabwino yopaka utoto, komanso kukana mwamphamvu, zomwe zimawapangitsanso kukhala okwera mtengo.
Ma lens a PC amagonjetsa kupsinjika kwa spherical ndi astigmatism mavuto omwe amayamba chifukwa cha kusinthika kwa magalasi achikhalidwe a TAC atapangidwa.Amakhala ndi mphamvu yotsutsa kwambiri (nthawi 60 kuposa ya magalasi agalasi, nthawi 20 kuposa ya magalasi a TAC, ndi nthawi 10 kuposa ma lens a resin) ndipo amagwiritsidwa ntchito kwambiri m'mabwalo amlengalenga ndi ankhondo.Nthawi yomweyo, ma lens a PC ndi opepuka, kukhala 37% opepuka kuposa magalasi omwe amapezeka kwambiri.
Kusiyana PakatiMagalasi a PolarizedNdipo Tinted Lens
Ma lens amangogwiritsa ntchito kuchepetsa kuwala, ndipo sangathe kusefa kuwala.Amangochepetsa mphamvu ya kunyezimira, kuwala kwa ultraviolet, ndi zina zotero, ndipo sangatsekeretu kuwala koopsa kumeneku.Panthawi imodzimodziyo, chifukwa cha kuwala kocheperako, kumakhudza kufalikira kwa ma lens, kuyika chiopsezo cha chitetezo kwa ovala.
