Magalasi a masewera

Magalasi a masewera ndi mbali yofunika kwambiri ya kufufuza kwa anthu onse omwe amatsogolera moyo wathanzi. Ojambula amapanga zitsanzo zamakono chaka chilichonse, pogwiritsa ntchito zipangizo zamakono komanso zowonjezereka, kuwongolera makompyuta, kupanga mawonekedwe abwino komanso othandiza. Monga mwa zonse, ndikofunika kusankha chitsanzo chabwino ndi masewera anu.

Magalasi amitundu yosiyanasiyana

Magalasi otetezera dzuwa - ali ndi mdima wambiri. Pali mitundu yambiri yopanga masewera mumzindawu (magalasi othamanga, kuthamanga njinga, kukwera ndi zina zotere) komanso zosangalatsa zomwe zimakhala zosangalatsa. Mwachitsanzo, paulendo wopita kumapiri kapena m'chipululu, magalasi okhala ndi dothi lolimba amafunika. Izi zimayambitsa kuwala kochepa komanso kutulutsa kuwala kwa disolo. Chotsatira chotsiriza chimasonyezedwa pa choyimika chapadera, mabome kapena chizindikiro. Pali magulu asanu:

• 0 - zosaoneka bwino kapena zowonongeka, zomwe pafupifupi dzuwa limadutsa;
• 1 - kuchokera 43 mpaka 80% - kuwala kofiira;
• 2 - kutumiza kwa kuwala ndikofanana ndi 18 - 43% - mlingo woyenera;
• 3 - dzuwa limalowetsa 8 - 18 peresenti;
• 4 - zopanda malire zoperewera - zosachepera 8%.

Mtundu wa Lens

Pachigawo ichi sichiwonetsero cha kukoma ndi kalembedwe, koma chinthu chomwe chimayikidwa ndi zochitika zakunja ndi zochitika:

1. Pa masewera a masewera, sankhani masewera a masewera ndi buluu kapena magalasi obiriwira. Adzapangitsa kusiyana kwa lupanga lachikasu motsutsana ndi maziko a munda.
2. Pogwiritsa ntchito galasi, mumayendera bwino mapulogalamu amkuwa - izi zimapereka chithunzi cha chithunzichi ndikuthandizira kuona mpira woyera ukuwala.
3. Ndiponso, mtundu wa amber lens umalimbikitsidwa kwa oyendetsa njinga ndi osaka. Kuvala magalasi pamagalasi oterewa kumachepetsa kuwala. Kawirikawiri, yonse yachikasu imakhala bwino m'madera otsika (madzulo, nkhungu, mitambo).
4. Pochita masewera olimbitsa thupi amadzi ndizofunikira - ntchito yawo yaikulu ndikutsegula m'mwamba madzi omwe amawonekera.
5. Zokondedwa ndi ambiri amtundu wautali wazindikira kuzindikira osati chifukwa chakuti - magalasi a mtundu uwu amapereka chiwombankhanga cha kuwala. Zimangowonjezera kuwala, popanda kusokoneza malingaliro a mtundu.
6. Mafilimu a masewera a nyengo yozizira, monga lamulo, sankhani masewera a masewera olimbitsa thupi ndi majekensi alanje kapena a bulauni. Kuti muwone chipale chofewa chomwe chili m'mphepete mwa nyengo, sankhani ma lalanje, ndipo tsiku lowala kwambiri, masewera abwino a masewera ndi ofiira. Kuchepetsa kuchuluka kwa kuwala komwe kumasonyezedwa ndi chisanu kumathandizira kuyang'ana kuvala.
7. Ndipo, potsiriza, magalasi owonetsera amkati, okondedwa a ambiri, amatha kuchepetsa kuwala kwa dzuwa kumaso athu. Amaonjezera kusiyana kwa fanolo, kupereka mpata wokondwera nawo malo.

Masewera a masewera a masewera ndi diopters . Ngakhale zilizonse zamakono zamakono, magalasi omwe alipo alipo sangathe kugwira ntchito yowonongeka. Chowonadi ndi chakuti mitundu yambiri ya ntchito zakunja imapangidwa ndi lenti lopindika kwambiri, ndipo kupanga diopters kumagwira ntchito makamaka ndi "malo apamwamba". Kuwonjezera pamenepo, kukonza maso ndi kupopera kwakukulu sikusankha bwino, chifukwa chithunzi chopotoka kwambiri chingangowonjezera mavuto a masomphenya, zomwe zimayambitsa kusokonezeka komanso kusokoneza .

Zochita za magalasi osewera masewera

Chofunikira kwambiri ndizo zomwe zipangizozo zimapangidwira. Ayenera kukhala amphamvu momwe angathere, koma kuwala. Zomwe zaposachedwapa - zopangidwa ndi mpweya wa kaboni, zomwe nthawi zambiri zimakhala zamphamvu ndipo nthawi imodzi ndi 75% kuposa nyansi. Kuyesera ndikutola magalasi anu, samalani kuti akambirane. Magalasi abwino amakhala ndi ma tempile osinthika, amakulolani kusankha chosinthika, malingana ndi kukula ndi mawonekedwe a mutu. Mfundo imodzi - ndodo imaima. Ndi nthawi yochita masewera olimbitsa thupi ndi thukuta lochuluka, sayenera kukupukuta, kukutsekani kapena kukulepheretsani. Anthu ambiri amangogula magalasi pamasewera otsekemera - amavala ngati momwe amachitira nthawi zonse, koma pazifukwa zina zimakhala zosavuta, zosavuta, komanso zofunika kwambiri, zimakhazikika pamutu.
