Nthawi yomwe atsikana ndi achinyamata ankachita manyazi ndi kuvala magalasi, atapita kale. Masiku ano izi zowonjezera kwa ambiri ndi gawo lofunika kwambiri la kalembedwe, chifukwa popanda chithunzicho sichidzakwanira. Olemba otchuka kwambiri padziko lonse lapansi nyengoyi amawona magalasi ngati chokongola kuwonjezera pa zovala, zomwe zimapereka chithunzi cha mwini wake chinsinsi, chiyambi ndi kugonana.
Ndi zachilendo kuti magalasi omwe ali m'magalasi aliwonse akuyenera kulingana ndi chikhalidwe cha ziwalo za munthu amene adzawaveke. Kotero, ngati mwamuna kapena mkazi ali ndi masomphenya angwiro ndipo sakuvutika ndi matenda a ophthalmic, magalasi opangira masewera ndi magalasi popanda diopters adzamutsatira iye. Zowonjezera zoterezi sizimakhudza kuwona, koma pa nthawi yomweyo zidzakongoletsa maonekedwe a mwini wake ndi kupereka chithunzi chake "zest" zokongola.
Kodi mungasankhe bwanji magalasi apakompyuta opanda diopters?
Zikuwoneka kuti zingakhale zophweka kusiyana ndi kusankha magalasi popanda diopters chifukwa chithunzi - ndi zokwanira kuti mupite ku salon iliyonse ya optics ndi kusankha choyenera chomwe chidzagogomezera ubwino ndi kubisala zolakwika, komanso kuti azikongoletsa chithunzi. Zingakhale chilichonse - chokwera kapena chamakona, chozungulira kapena chowulungika, chopangidwa ngati "diso la paka" kapena "aviator." Chirichonse chimadalira kokha pa zomwe zimaperekedwa kwa iwe mwachilengedwe, ndi zomwe iwe ukuyesera kuti uzipindule mwa kuvala magalasi oterowo.

Ngakhale anthu ambiri amakhulupirira kuti magalasi wamba amagwiritsidwa ntchito m'magalasi amenewa, makamaka izi siziri choncho. Kwa lenses- "nulevkam", yomwe imayikidwa mu magalasi oterowo, zofunikira zina zimapangidwanso. Ngati mankhwalawo sali apamwamba, adzalimbikitsa kutopa kwa maso, kuchepa kwa masomphenya komanso kukula kwa mutu.
Pofuna kupewa izi, muyenera kusankha magalasi opanda ma dioptries, mapulogalamu omwe amapangidwa ndi pulasitiki kapena galasi ndipo amaphimbidwa ndi mipando yapadera, yomwe imateteza kutentha, fumbi ndi chinyezi. Pa nthawi imodzimodziyo, zigawo zingapo za zobvala zoyenera kuzigwiritsira ntchito ziyenera kugwiritsidwa ntchito pamwamba pa disolo, mwinamwake kuwala sikudzapangidwira m'maso, zomwe zingayambitsenso kuwonongeka.
Kuphatikiza pa "zero", pali mitundu ina ya magalasi popanda diopters, yomwe imagwiritsidwa ntchito osati kungoimitsa chithunzichi, komanso kukwaniritsa zolinga zina, mwachitsanzo:
- Magalasi amdima popanda diopters ndi njira yosavuta yotetezera kuwala kwa ultraviolet. Mukhoza kuvala okha mumsewu komanso tsiku loyera bwino, pamene kuwala kwa dzuŵa kungakhumudwitse maso anu ndi kukhumudwitsa chitukuko chosiyanasiyana cha maso . Mu chipinda, magalasi oterowo ayenera kuchotsedwa;
- Magalasi ojambula zithunzi omwe sakhala ndi ma diopters amatha kuonekera pamene munthu alowa m'chipindamo, ndipo nthawi yomweyo amdima pamene kuwala kwa ultraviolet kumayamba kukhudza magalasi. Chipangizo choterechi chingagwiritsidwe ntchito pazochitika zilizonse, zomwe mosakayikira zimakhala zosavuta;
- magalasi opanda diopters pamakompyuta apangidwa kwa iwo omwe amathera nthawi yambiri kutsogolo kwa chowunika. Zowonjezerazi zimachepetsa kwambiri vuto la maso, zimapangitsa kuti ziwoneka bwino ndikukulolani kuti muzigwira ntchito nthawi yaitali popanda kutopa.

Mulimonsemo, magalasi aliwonse osasankhidwa, muyenera kumvetsa kuti simungawasunge nthawi zonse. Povala zovala zoterezi, mbali yowonongeka imakhala yochepa kwambiri, yomwe ingasokoneze mkhalidwe ndi ntchito ya maso.
