Chilimwe chafika, kuwala kwadzuwa kukukulirakulira ndipo dzuwa likukulirakulira. Kuyenda mumsewu, sikovuta kupeza kuti anthu ambiri amavala magalasi a photochromic kuposa kale. Magalasi a myopia ndizomwe zikukulirakulira kwamakampani ogulitsa zovala zamaso m'zaka zaposachedwa, ndipo magalasi a Photochromic ndi chitsimikizo cha kupirira kwa malonda achilimwe. Kuvomerezedwa kwa magalasi a photochromic ndi msika ndi ogula amachokera ku zosowa zosiyanasiyana monga makongoletsedwe, chitetezo chopepuka komanso kuyendetsa galimoto.
Masiku ano, anthu ochulukirachulukira akudziwa za kuwonongeka kwa cheza cha ultraviolet pakhungu. Zodzitetezera ku dzuwa, ma parasol, zipewa zokwera pamwamba, ngakhalenso manja a silika a ayezi zakhala zofunika kwambiri popita kotentha. Kuwonongeka kwa cheza cha ultraviolet m'maso sikungakhale kofulumira ngati khungu likufufuzidwa, koma m'kupita kwanthawi, kuwonetseredwa mwachindunji kungakhale ndi zotsatira zoopsa kwambiri pa maso.
MFUNDO YOSINTHA MITUNDU: PHOTOCHROMMISM
Mtundu wa lens wa photochromic umakhala wakuda panja, kufika pamtunda wofanana ndi wa magalasi a dzuwa, ndipo mawonekedwe a kubwerera ku nyumba zopanda mtundu komanso zowonekera zimagwirizana ndi lingaliro la "photochromic", lomwe likugwirizana ndi chinthu chotchedwa silver halide. Panthawi yopanga, opanga ma mandala amawonjezera tinthu tating'ono ta siliva halide microcrystalline ku gawo lapansi kapena filimu yosanjikiza ya mandala. Kuwala kolimba kukayatsidwa, siliva halide imawola kukhala ayoni asiliva ndi ma halide ions, imatenga kuwala kochuluka kwa ultraviolet ndi gawo la kuwala kowoneka; pamene kuwala kozungulira kumakhala mdima, ma ion siliva ndi ma ion halide amatsitsimutsanso siliva halide pansi pa kuchepetsedwa kwa oxide yamkuwa, ndipo mtundu wa mandala umakhala wopepuka mpaka ubwerera ku mtundu wopanda utoto komanso wowonekera.
Kusintha kwa mtundu wa magalasi a photochromic kumachitika chifukwa cha kusintha kwamitundu yosiyanasiyana. Kuwala (kuphatikiza kuwala kowoneka ndi kuwala kwa ultraviolet) kumathandizanso kwambiri pakuchitapo kanthu. Mwachibadwa, zimakhudzidwanso ndi nyengo ndi nyengo, ndipo sizimasunga nthawi zonse kusintha kwamtundu wokhazikika komanso kosasinthasintha.
Nthawi zambiri, nyengo yadzuwa, kuwala kwa ultraviolet kumakhala kolimba, ndipo mawonekedwe a photochromic amakhala amphamvu, ndipo kuya kwa magalasi owoneka bwino nthawi zambiri kumakhala kozama. Pamasiku a mitambo, kuwala kwa ultraviolet kumakhala kofooka, ndipo kuwunikira sikolimba, ndipo mtundu wa lens udzakhala wopepuka. Kuonjezera apo, pamene kutentha kumakwera, mtundu wa lens photochromic udzakhala wopepuka pang'onopang'ono; Mosiyana ndi zimenezi, kutentha kumachepa, mtundu wa lens photochromic pang'onopang'ono udzakhala wodetsedwa. Izi zili choncho chifukwa kutentha kukakhala kokwera, ma ion a siliva owonongeka ndi ma halide ions adzachepetsedwa kachiwiri pansi pa mphamvu yamphamvu kuti apange siliva halide, ndipo mtundu wa lens udzakhala wopepuka.
Pankhani ya magalasi a photochromic, pali mafunso awa omwe amapezeka ndi chidziwitso:
1. KODI MA PHOTOCHROMIC LENSES ADZAKHALA NDI ZOYAMBIRA ZOYENERA ZOYENERA / ZOYENERA KUPOSA MALENSI WANTHAWI ZONSE?
Magalasi a Photochromic aukadaulo wapamwamba kwambiri wa Photochromic alibe mtundu wakumbuyo, ndipo kuwalako sikudzakhala koyipa kuposa magalasi wamba.
2. CHIFUKWA CHIYANI PHOTOCHROMIC LENSES SASINTHA COLINA?
Kusintha kwa mtundu wa magalasi a photochromic kumagwirizana ndi zinthu ziwiri, imodzi ndi mikhalidwe yopepuka, ndipo ina ndi kusintha kwa mtundu (silver halide). Ngati sichisintha mtundu pansi pa kuwala kwamphamvu ndi kuwala kwa ultraviolet, mwina ndi chifukwa chakuti kusintha kwa mtundu wake kwawonongeka.
3. KODI KUSINTHA KWA ZINTHU ZA MA PHOTOCHROMIC LENS KUDZAKHALA AYI CHIFUKWA CHAKUGWIRITSA NTCHITO KWANTHAWI YOtalikirapo?
Monga mandala aliwonse wamba, magalasi a photochromic amakhalanso ndi moyo wautali. Ngati mumvera kukonza, nthawi yogwiritsira ntchito nthawi zambiri imafika zaka 2 mpaka 3.
4. N'CHIFUKWA CHIYANI MA PHOTOCHROMIC LENSES AMATHANDIZA KUKHALA ATAWAVALA KWA NTHAWI YATALI?
Magalasi a Photochromic amakhala akuda mumtundu atavala kwa nthawi yayitali, ndipo sangathe kutembenuzidwanso kuti awonekere chifukwa zinthu zosintha mtundu zomwe zili mkati mwake sizingabwerere m'malo mwake zitasintha, zomwe zimapangitsa mtundu wakumbuyo. Chodabwitsa ichi nthawi zambiri chimapezeka m'magalasi osawoneka bwino a photochromic, koma sizichitika m'magalasi abwino a photochromic.
5. N'CHIFUKWA CHIYANI MA LENS OGIRITSIDWA NDI ODALIRA KWAMBIRI PAMsika?
Magalasi otuwa amatenga IR ndi 98% ya kuwala kwa UV. Ubwino waukulu wa lens imvi ndikuti sichidzasintha mtundu wapachiyambi wa zochitika chifukwa cha lens, kuchepetsa mphamvu ya kuwala. Magalasi otuwa amatha kuyamwa mtundu uliwonse wamtundu wofananira, kotero kuti zowonera zitha kukhala zakuda, koma sipadzakhalanso chromatic aberration, kuwonetsa kumverera kowona komanso kwachilengedwe. Kuonjezera apo, imvi ndi mtundu wosalowerera, woyenera magulu onse a anthu, komanso wotchuka kwambiri pamsika.
Ngati mukufuna kudziwa zambiri za mafashoni a magalasi komanso kufunsira kwamakampani, chonde pitani patsamba lathu ndikulumikizana nafe nthawi iliyonse.
