"Polarized? Polarized chiyani? Magalasi a polarized?"

"Polarized?Magalasi a polarized?"
Nyengo ikutentha
Yakwana nthawi yoti muwononge kuwala kwa ultraviolet kachiwiri
Lero, tiyeni tonse tiphunzire za magalasi a polarized ndi chiyani?

 

Ndi chiyanimagalasi a polarized?

Magalasi adzuwa amatha kugawidwa kukhala magalasi a polarized ndi magalasi wamba kutengera ntchito yawo.
Magalasi a dzuwa: Magalasi amatha kutsekereza kuwala kwa dzuwa ndi kuwala kwa ultraviolet. Pamwamba pa izo, iwo ali ndi polarizing filimu wosanjikiza amene angathe kuletsa kuwala kwa njira inayake, potero kukwaniritsa zotsatira zopewera glare.
Magalasi wamba: Magalasi amakhala opindika kwambiri, amachepetsa kufalikira kwa kuwala kutsekereza kuwala kwa dzuwa ndi kuwala kwa ultraviolet popanda kuletsa kunyezimira.

Kodi mfundo yamagalasi a polarized?

Ma lens opangidwa ndi polarized amapangidwa potengera mfundo ya kuwala kwa polarization. Kuwonjezera pa kuteteza kuwala kwa ultraviolet ndi kuchepetsa mphamvu ya kuwala, amathanso kusefa kuwala. Izi zimalola kuti kuwala kochokera kunjira inayake kumadutse pa ma lens axis ndikulowa m'maso kuti apange chithunzi chowoneka bwino, kupondereza bwino kusokonezedwa ndi magwero osiyanasiyana akunja akunja ndikuletsa kuwala kwa dzuwa kuti lisawoneke bwino, kupangitsa kuti mawonekedwewo amveke bwino.
M'mawu a layman: Kugwira ntchito kwa ma lens kuli ngati kuyika zotchingira maso, zomwe zimalola kuti kuwala kwapadera kokha kulowe ndikuchepetsa kusokonezedwa ndi magwero amwazikana.

Kodi pali kusiyana kotanimagalasi a polarizedndi wambamagalasim'mawonekedwe?
Palibe kusiyana koonekeratu, koma kuvala kumamva mosiyana kwambiri. Yesani kukhala ndi dziko latsopano lowoneka.

Ndizochitika ziti zomwe ndizoyenera kuvala magalasi a polarized?
Zochita zamadzi (osachepera nthawi yantchito)
Usodzi (osati ulimi wa nsomba)
Kuyendetsa (osati kuthamanga)
Kusewera gofu (komanso kusewera tenisi, badminton, kapena masewera aliwonse a mpira)
Kusambira, misasa, kukwera miyala, kukwera maulendo
Pamene muyenera kubisa mabwalo amdima chifukwa cha kusowa tulo
Panthawi yopangira mano monga kudzaza, kuchotsa dzino, kapena kuyeretsa (kungachepetse mantha a mano)
Atha kugwiritsidwa ntchito m'magulu azachipatala pa matenda a maso ndi maopaleshoni
Kodi anthu omwe ali ndi myopia amavala magalasi a polarized?
Inde. Kwa anthu a myopic, m'pofunika kusankha magalasi adzuwa omwe angathe kuikidwa ndi magalasi a mankhwala. Masiku ano, magalasi ena a dzuwa amatha kuikidwa magalasi omwe amalembedwa ndi dokotala, koma pali zoletsa zambiri panthawi yoyenerera.

Momwe mungasankhire zogwira mtimamagalasi a polarized?

(1) Onani kuchuluka kwa polarization
Kuchuluka kwa polarization ndiye gawo lalikulu lowunika momwe ntchito ya polarizing imagwirira ntchito. Nthawi zambiri, kuchuluka kwa polarization kumakwera, mphamvu ya lens yotchinga kuwala, kuwala kowoneka bwino, ndi kuwala kwina komwazika; kuchuluka kwa polarization kwa magalasi abwino kwambiri kumatha kupitilira 99%.
(2) Kumvetsetsa ukadaulo wa polarizing wa mandala
Kupondereza kwa masangweji achikhalidwe kumatha kubweretsa madigiri olakwika komanso magalasi akulu. Njira yatsopano yophatikizira, "kuphatikizana kwachidutswa chimodzi," ndi yolondola komanso yokhazikika, yosapanga mapangidwe a utawaleza, ndipo imapangitsa kuti lens ikhale yopepuka komanso yocheperako.
(3) Sankhani magalasi opangidwa ndi polarized ndi ma lens okutidwa
Kupaka pa ma lens kumapangitsa kuti ma lens a polarized awonekere. Opanga magalasi ambiri savala magalasi awo okhala ndi polarized, zomwe zimachititsa kuti madzi, mafuta, ndi fumbi asamagwire bwino; m'malo mwake, opanga ali kale ndi umisiri wabwino kwambiri wokutira womwe ungagwiritsidwe ntchito pa magalasi a polarized kuti magalasi akhale osavuta kugwiritsa ntchito komanso olimba.
(4) Chitetezo cha Ultraviolet
Musaiwale, magalasi a polarized akadali magalasi; amangowonjezera polarizing zotsatira. Chifukwa chake, zofunikira zoyambira magalasi adzuwa zimagwiranso ntchito kwa iwo. Magalasi abwino kwambiri opangidwa ndi polarized ayeneranso kukwaniritsa UV400, kutanthauza kuti zero ultraviolet transmittance.
