Kodi chidwi chosambira ndi maso otsekedwa? Makamaka pankhani yosambira panyanja kapena nyanja, komwe pansi ndi kosaoneka kwambiri kuti simusangalatsa kukongola kwake - ndi tchimo chabe. M'nkhaniyi tidzakuuzani momwe mungasambitsire zosangalatsa, zosangalatsa komanso zokoma.
Masewera osambira
Mvetserani chidwi chonse cha kuthawa ndi kusambira kungatheke pogwiritsa ntchito magalasi apadera. Zimavomerezedwa kusiyanitsa mitundu yosiyanasiyana ya mfundo:
- ana;
- wosangalatsa;
- kuyambira;
- magalasi osambira ndi diopters.
Masks okhala ndi diopters adzakhala othandiza kwa osambira omwe ali osawona bwino , omwe m'moyo weniweni amavala magalasi, ndi anthu omwe amawona bwino. Popeza, kugwira pamwamba pa madzi, kuwala kwa dzuwa kumatsitsimutsidwa, chithunzi pansi pa madzi chikuwonekera mozama kwambiri kusiyana ndi chenichenicho. Choncho, ngakhale wosambira ndi maso abwino adzawona zonse ziri mu mphuno, koma magalasi apadera akusambira ndi diopters adzathandiza kuti dziko lapansi pansi pa madzi likhale loyera ndi loyera.
Ndikofunika kumvetsetsa kuti kuvala magalasi okhudza makina ndi masewera osambira, simungakwanitse kuwoneka bwino pansi pa madzi. Kuphatikiza apo, ngati madzi alowa pansi pa magalasi kapena maskikiti, magalasi amatha kutsukidwa ndikusiya kupuma pansi pa dziwe kapena thupi lachilengedwe.
Kodi masewera osambira ndi diopters ndi chiyani?
Kugula masikiti kapena magalasi okhala ndi diopters sizingatheke - iwo sagulitsidwa basi. Malonda a masewera ndi masikiti akusambira ndi diopters amagulidwa payekha (kuphatikizapo magalasi wamba kuti awone masomphenya) ndipo akhoza kuikidwa ndi manja awo. Malingana ndi msinkhu wa masomphenya, makondomu amasankhidwa. Izi sizikutanthauza kugula magalasi pamadzi omwe ali ndi diopters yomweyo, ngati kuli koyenera, malonda a maso osiyanasiyana angathe kusankhidwa mosiyana.
Kumbukirani kuti mphamvu ya magalasi idzagwira ntchito pansi pa madzi, kotero, kuvala magalasi atsopano osambira, sikuyenera kuwopsyeza - zonse zidzawoneka zosavuta, ndipo izi ndi zachilendo.
Sankhani magalasi a masewera kapena kusambira kwasungwana ndi zojambula zofunikira, malinga ndi mapeto a oculist. Mphamvu ya lentiyo iyenera kukhala yofanana ndi magalasi oyenera, ndiye pansi pa madzi mumamva bwino. Chinthu china chofunikira cha kusankha ndicho khalidwe. Ndibwino kuti tigule malonda kuchokera ku malo odziwika bwino, omwe ayesedwa zaka zambiri, ngati atakhalapo nthawi yaitali, ndipo amatsimikizira kuti ali otetezeka, komanso ofunika kwambiri - otetezeka, masewera a masewera.
