Kodi munasankha magalasi oyenera?

Chifukwa cha kuwala kwa dzuwa m'chilimwe, kodi zimakupangitsani kuti musatsegule maso anu?Anthu ambiri amakonda kuvala peyala yayikulumagalasipoyendetsa galimoto kapena potuluka pofuna kuteteza kuwala kwa dzuwa.Koma, kodi mwasankha magalasi oyenera?Ngati musankha magalasi olakwika, sangateteze maso anu, ngakhale “kukuchititsani khungu” ndi kuyambitsa ngozi zapamsewu pazifukwa zazikulu.Zikuwoneka ngati funso losavuta kunyamula magalasi oyenera, koma pali kusamvetsetsana kwakukulu.

Kenako, ndikufuna kufotokoza zina zolakwika posankha magalasi:

Bodza 1: Mtundu wakuda, umakhala bwino

Anthu ambiri amazitenga mosasamala kuti mtundu wa lens ukakhala wakuda, ndiye kuti chitetezo cha UV chimakhala bwino.Ndipotu, ntchito yamagalasikusefa kuwala kwa ultraviolet kumangogwirizana ndi filimu yophimba, ndipo mtunduwo suli wakuda momwe mungathere.Makamaka kwa oyendetsa mtunda wautali, ngati magalasi akuda kwambiri, maso amakhala otopa kwambiri, komanso zimakhala zoopsa kwambiri kulowa mu tunnel ndi malo ena omwe ali ndi kuwala kochepa mwadzidzidzi kuchokera ku dzuwa lamphamvu.

Bodza lachiwiri: Magalasi opangidwa ndi polarized ndi abwino kwambiri

Madalaivala ambiri amakonda kuvalamagalasi polarized.Zowonadi, magalasi opangidwa ndi polarized amatha kuchepetsa kuwala kwamphamvu, kuthetsa kunyezimira, ndikupanga mzere wamaso kukhala wachilengedwe komanso wofewa.M'malo mwake, magalasi okhala ndi polarized ndi oyenera kupha nsomba, kusefukira ndi malo ena owoneka bwino koma osati nthawi zonse.Mwachitsanzo, dalaivala nthawi zina amayenera kuyang'anizana ndi malo amdima monga mumsewu, pamene lens ya polarized ndi yosavuta kupanga maso mwadzidzidzi mumdima zomwe ziri zoopsa kwa dalaivala.Kuphatikiza apo, ma lens opangidwa ndi polarized amapeputsa mtundu wa zowonera za LCD ndi nyali zamagalimoto a LED.Chifukwa chake, musanasankhe magalasi adzuwa, ndikofunikira kuganizira nthawi yayikulu yomwe mungakhale nayo ndi sunshades.Magalasi opanda polarized akhoza kukhala oyenera kwa inu.

Bodza lachitatu: Osavala magalasi a myopia

Madalaivala ena ndi a myopic pang'ono, ndipo palibe vuto kuyendetsa popanda magalasi a myopic nthawi wamba.Koma mukangovalamagalasi, vuto limabwera: maso anu amatopa kwambiri, ndipo maso anu amachepa, monga momwe maso anu amakhudzidwira poyendetsa galimoto usiku.Chifukwa chake, madalaivala omwe ali ndi myopia yofatsa amatha kuyendetsa popanda vuto lililonse.Ngati akufuna kuvala magalasi, ayenera kukhala ndi magalasi okhala ndi digiri ya myopia.

Nthano4: Mtundu wa magalasi ndi wokongola kwambiri

Achinyamata owoneka bwino adzakhala ndi magalasi amitundu yosiyanasiyana.N’zoona kuti amawoneka bwino, koma sayenera kugwiritsidwa ntchito poyendetsa galimoto.Mwachitsanzo, magalasi a pinki ndi ofiirira amasintha mtundu ndi mawonekedwe.M'malo mwake, ndi bwino kugwiritsa ntchito magalasi a imvi pamagalasi, chifukwa sizingasinthe mtundu woyambira.Chotsatira ndi chobiriwira chakuda.Magalasi abulauni ndi achikasu amatha kuwongolera kuwala ndipo ndi oyenera malo okhala ndi chifunga komanso fumbi.

Poyendetsa galimoto m'chilimwe, muyenera kusankha zoyeneramagalasimalingana ndi momwe mulili kuti mupewe ngozi zoyendetsa galimoto.
