Choonetsedwa Kusintha - ndichiyani? magalasi: makhalidwe ambiri, maonekedwe, mitundu, zithunzi

kusawona wamba lero. Komabe, pali zipangizo kuwala, kulola kuti athetse vutoli. Onani mmene munthu wathanzi, kuthandiza magalasi. Ndi chiyani icho? Izi mankhwala wapadera kuti ntchito zonse mu refraction, ndi malawi.

Chiopsezo kugula mankhwala zosaoneka

Masiku ano, zipangizo kuwala kwa kukonza masomphenya amagulitsidwa kulikonse. Iwo zikhoza kugulidwa ngakhale underpasses lapansi. Koma ngati muyenera kukhulupirira khalidwe lawo? Anthu ambiri sitinaonepo kugula ophthalmic, monga magalasi asinthe. Kodi iwo sadziwa. Kungowerenga kufunika kugula mankhwala amenewa, akalakwa. Chifukwa, iwo ali m'mavuto zoipa:

• Munthu amayamba kuona kutopa mu maso ndi masomphenya akupitiriza kuwonongeka;
• otsika kwambiri chimango limakhumudwitsa khungu, zikubweretsa thupi lawo siligwirizana;
• magalasi kuyang'ana inharmonious, chifukwa mwini awo sanali kofunika kuti maonekedwe a mankhwala.

Choti?

Kusankha magalasi, icho chiri - muyenera kudziwa kwenikweni. Izi katundu ophthalmic, zimatanthauza kugula ake ayenera kumwedwa ndi udindo. Muyenera kugula okha mu salons wa Optics. Mbali yaikulu gawo la mankhwala likulowa. zingapo mitundu yake kulekanitsidwa:

• Chimodzi-chidutswa. Ndi maziko disolo kwathunthu.
• Poluobodkovaya. Iwo ali yekha kumtunda m'mphepete. Komanso atathana mandala. Galasi ndi ufulu pansi.
• Rimless. m'mbali asalandidwe. Zikumangireni chikugwirizana mwachindunji galasi. Chotero mafelemu kwa magalasi kukonza muli mchitidwe yolusa iwo.

Monga zipangizo zitsulo ntchito, komanso ma polima. Mafelemu zopangidwa nthochi, tinganene kuti mtundu wa zachilendo.

Ngati mukufuna kukhala ndi mwiniwake wa mankhwala apamwamba, onetsetsani kuona ntchito. zikalata anasonyeza GOST 51193-98. Pali malonda oipa amene kulenga magalasi, chimene icho chiri, sindikumvetsa. Iwo ayenera kukhala molingana ndi malamulo. Iwo zonse specifications ambiri.

Mfundo akhoza kuona ngati mankhwala amene amachititsa kuwukonza zofunika mankhwala. Kuwala zida analenga zinthu zinawonongeka, angabweretse chiopsezo ku thanzi la munthu. Ndipo apa wapangidwa mogwirizana ndi zofunikira za magalasi GOST kukonza zikhoza kugulidwa mosavuta.

Kodi mandala kusankha?

Pakuti yopanga magalasi ntchito galasi mchere ndi zipangizo za chiyambi organic. Mbali yoyamba pali chinthu mandala. Iwo apangidwa pambuyo kuzirala amphamvu a zigawo poyamba kusungunuka galasi-n'kupanga. The magalasi chifukwa ali wolemera kwambiri, koma mwangwiro kupewa maganizo makina. mankhwala pulasitiki, Mosiyana, akulemera pang'ono. Komabe, magalasi amenewa amafuna ❖ kuyanika zina kuteteza kukanda.

Njira makampani Russian ndi achilendo

opanga zoweta akwanitsa katswiri yopanga magalasi kwa magalasi kudetsa njira. Amagwiritsa ntchito zinthu zosiyana ndi katundu dzuwa kulamulira. Nthawi zambiri mukhoza kuona mankhwala a imvi bulauni. Komabe, msika pali zambiri zimalimbikitsa mitundu: wobiriwira, buluu, chikasu. America amakonda imvi galasi, ndi azungu - bulauni.

makampani Russian amakhala umasinthasintha kusankha mtundu. Kunja Komano, amakonda kuganizira moyo wa makasitomala. Anthu a kudzinenera kulenga kupereka magalasi ndi magalasi imvi. Zamgululi kuchepetsa kusiyana wobiriwira ndi buluu ndi buluu wodzipangitsa zochepa zimalimbikitsa. Brown galasi, ndi zofunika Ndinapereka madalaivala ndi zambiri anthu amene kuwononga nthawi panjira. Ngati wodwala tiyenera kusunga khalidwe la mtundu ndi kuonjezera kusiyana pa nthawi yomweyo, kumafuna mandala wobiriwira. Iwo oimira pantchito monga njinga yamoto racers, oponya mivi, golfers.

Akukhulupirira kuti magalasi ndi magalasi chikasu ndi chosiyana sporty tione. Koma akatswiri amalangiza iwo okha kwa anthu nawo tenesi. Iwo kusintha lathu la player pa bwalo.

Ngati muli Kwalamulidwa magalasi, ndemanga ayenera kufufuza kwenikweni - iwo akuuza zambiri zothandiza. Ndemanga zosiyana, chifukwa apa, monga mu nkhani ya mankhwala, izo zidalira pa mtima ndi mankhwala Mlengi wa zinthu zenizeni.

magawo zofunika

Ngati masomphenya zimasiyanasiyana 0.5 kuti 0,05 ankafunika masewera telescopic. Iwo ogwira zolakwa refractive, ndi kuwonjezeka kwambiri kukula kwa zinthu. mankhwala alipo pa oipa ndi mandala positive.

magalasi Prism anapangidwa kuti odwala matenda matenda a minofu diso. prisms awiri, pano m'menemo, refract cheza pa makona a madigiri 90. Chifukwa munthu uyu akhoza kuika bukhu pa chifuwa chake, ndipo angathe kuona zimene zinalembedwa izo. Optics amenewa amapereka singasiyanitsidwe thandizo odwala chigonere.

Nthawi zina, ophthalmologists mankhwala magalasi n'zofanana asinthe. Ndi chiyani icho? Iwo ndi katundu Kuganizira ntchito anthu ndi hemianopsia unilateral.

Akatswiri nthawi kulemba mankhwala magalasi, munali zoikamo chindunji:

• mtunda pakati pa malo magalasi kuwala kwa wina ndi mzake;
• pamwamba chithunzi cha maso onse;
• mulingo woyenera kusamutsidwa wa pakati;
• cholinga Optics.

Kudziwa mphamvu kuwala kwa chida ntchito - dioptrimeter. Mwa maphunziro onse pochiza matenda a maso. Zimafunika nthawi kukaona dotolo diso kusiya matenda langoyamba.

zitsanzo zina amafuna kukonza magalasi mwauchidakwa, pamene ena amasiyana khalidwe wodzichepetsa. Zovuta ambiri zimachitika ndi Optics, kulola kuthetsa mavuto enieni, monga astigmatism, mwachitsanzo. Nchifukwa nthawi zina nkhani anasankhidwa ndi akatswiri, ndi mavuto. Iwo ndi azolowere pang'onopang'ono.

Tsopano showrooms magalasi anapanga zithunzi kupereka tione apo pomwe pa malopo. Nthawi zina maluso awo kuwala upambana chovomerezeka. Iwo ayenera kukhala osamala. Makasitomala zina anagula ophthalmic Optics pasadakhale.

Madokotala amalangiza kusiya kuvala kukonza magalasi zitsanzo munthu pa maziko mosalekeza. Ndi bwino kugwiritsa ntchito iwo nthawi Mwachitsanzo, pamene inu apite kumbuyo gudumu. Mukhoza kuvala iwo pamene ntchito ndi mbali, ndi wamfupi.

Kusankha mankhwala malinga ndi mtundu wa munthu

Choncho, gawo ongolankhula amaphunzira tikhoza tsopano ndikuganiza za kupanga njira amafunika magalasi. Iwo sayenera tisiye maganizo awo kwa mwini awo. Kumene, mukhoza kusankha mawonekedwe chipatso payokha. Koma sitiyenera kuiwala malamulo ochepa amene amaonedwa zofunika.

1. Ti- ndi poluobodkovye mafelemu ali osavomerezeka eni a mtundu elongated wa munthu. Anthu amenewa ndi bwino kugula sing'anga-kakulidwe magalasi.
2. Zamgululi ndi ndegeyo mkulu, chabwino kwa eni ndi mphumi lonse.
3. Magalasi ndikuoneka otsika-slung kukhala kwambiri ndi anthu aakulu mphuno. Mukhoza kugwiritsa ntchito chimango chachikulu cha mithunzi mdima. ntchito zabwino mlatho awiri. malangizo ofanana angaperekedwe kwa anthu ndi chibwano lalikulu. Ngati mbali zonse nkhope mwa anthu kuja, kugwiritsa ntchito njira iliyonse mfundo zovomerezeka.

Kusankha mtundu

Anthu ndi tsitsi tsitsi ali oyenera kukonza magalasi rimmed ndi siliva kapena mtundu golide. Mkuwa mtundu ikuoneka eni a tsitsi lofiira, pamene Brown akhoza amalangiza bulauni, golide kapena wofiira. Loderapo, M'malo mwake, ayenera kutengedwa wakuda.

Kusankha malinga ndi zovala

magalasi Mokhwima ali mwangwiro pamodzi ndi suti yantchito. njira Tsogolo akulimbikitsidwa kalembedwe msewu. Iwo ali otchuka pakati pa achinyamata. mankhwala otere nthawi zambiri amapezeka pakati pa Optics ndi mafelemu polima.
