Autorefractometry - ndichiyani nanga ikuchitika?

Poona fundus kudzera kufalitsa m'malovu ana wapita. M'malo chakale zida kompyuta pakubwera njira zatsopano. Ndithudi amene anakakamizika kuvala magalasi kapena kulankhula, adamva mawu "autorefractometry". Ndi chiyani icho? Yesetsani kumvetsa.

autorefractometry ndi chiyani?

Autorefractometry - ndondomeko pakompyuta amene amasanthula diso kudziwa matenda monga patali, patali zokha, astigmatism. Kukongola kwa njirayi ndi liwiro ndi olondola ndipo zotsatira zake. chipangizo molondola ndipo mu nthawi yochepa Mzimuyo kodi refraction diso. Zimenezi zimathandiza kuti alandire ndondomeko akuluakulu ndi ana. Kodi mtundu wa ndondomeko? Tiyeni kukambirana mwatsatanetsatane.

The refraction diso - ndi ndondomeko zovuta, amene amayamba ndi dongosolo kuwala moyo. M'mawu ena, diso la munthu zoti zovuta. Tingaone chifukwa chakuti mtengo kuwala likulowerera diso, kenako akafika kutsogolo kwa kamera ndi mandala, ndiyeno yekha thupi vitreous, amene refracts kuunika kotero kuti lolunjika pa diso. Chidwi mfundo: mphindi pamene kuwala imagwera pa diso, chifanizo chikuoneka mozondoka, ndi pokhapo adziwonetsa nyemba, fano mwachizolowezi amapezeka kutsogolo kwa ife. Ngati si malo awa, ndiye munthuyo kuzindikira dziko chadodolido.

phunziro refraction

Ngati tikambirana liwu "refraction", izo zikutanthauza luso la refraction kuwala diso. Pofuna kusonyeza refraction, anadziwana dongosolo lino la muyeso monga diopters. Pankhani kuyeza refractive index mu ofesi maso, iwo amaganiza zotsatira matenda, pamene chilengedwe cha refraction Mwachibadwa, thupi. kafukufuku pa chipatala amalola kuganizira malawi. Chifukwa luso limeneli munthu ali ndi mwayi kuganizira chinthu, kaya mtunda ake. Mayesero ikuchitika mu ofesi ya adokotala, n'zotheka kudziwa malawi ndi kudziwa bwino kuchita ntchito imeneyi. Choncho, tinganene kuti autorefractometry choterechi pochiza matenda a maso. Izi ndi njira cholinga cha poona makhalidwe a diso ndi mphamvu yake kuyamwa ndiponso kuonetsa kuwala kuwala.

njira zofufuzira

The refraction diso - ichi ndi mfundo zofunikira maso ndi. Ndi kuyamika zizindikiro kukopedwa autorefractometry angazindikire kuvutika mu kugwira ntchito zida za zithunzi. Choncho, njirayi chapeza wotchuka kwambiri mankhwala kuchipatala. Survey sizingatheke popanda chipangizo wapadera - ndi refractometer. Limeneli liyenera akuchita kudziletsa mayesero amasonyeza chifukwa, chimene, sosbtvenno ndi unachitikira autorefractometry. Zotsatira Decoding anachita ndi maso ndi. Iye amayang'ana pa zolozera phindu refraction, ndiyo awiri ndi magwiridwe a diso, ndi linaŵerengera ndi utali wozungulira kupatuka kupindika.

Kuti zotsatira kukhala zolondola, m'pofunika kuti achotse irritants onse diso. Izi ndi zofunika kuonetsetsa kuti diso anali pa mtendere, ndipo iye saletsa, chifukwa owonjezera minofu chidule zingabweretse zotsatira wolakwika, Izi zidzapangitsa kuti zotsatira zoipa. Popewa izi, odwala akulimbikitsidwa kuganizira chithunzi, amene ali kutali kwambiri. Chidwi mfundo: m'mbuyomu monga zithunzi ntchito mfundo yosavuta, tsopano mu makina atsopano, pali mpira chifanizo kapena mitengo Christmas, amene amalola unit kudziwa magawo yeniyeni.

Mfundo zikugwira ntchito chipangizo

Pa nthawi imene wodwala akuyang'anitsitsa pa chithunzi, adokotala akuyamba makina ndipo amayamba autorefractometry. Nchiyani, kuphunzira mwina kumvetsa. Kwa iye, ndondomeko ndi sabweretsa chisoni ndipo sayambitsa nkhawa. Mtengo infuraredi watumidwa ku diso refracted kangapo, mpaka, mpaka umalandira fundus wa diso ndi diso. Pambuyo pake, zikuoneka kuti zimaonekera kumeneko ndi kubwereranso. Nthawi imene kubwerera mtengowo uli njira yaikulu. Njira imeneyi wakhala zizipezeka mkubwela kwa refractometer, chifukwa kuthana ndi ntchito munthu sangathe kuchita.

ubwino autorefractometry

Anthu anayamba kalekale anayamikira ubwino umene umabweretsa autorefractometry. Kodi ndizofunikira kudziwa aliyense, chifukwa watilola amanena siteji koyamba za mavuto maso anga ndi zolakwika zindikirani. Autorefractometry, amene Akulamulira zodziwika bwino ndi chizindikiro, mosavuta kuchitidwa mu malo chachikulu matenda, kotero kuwatenga kukaonana ndi dokotala, amene ali chipangizo tatchulazi.

Komanso ndi njira yaikulu kuphatikiza ndi:

• Umboni wa patali zokha ndipo patali;
• pluchenie magawo bwino;
• n'zotheka kupeza deta anisometropia ndi mmene ake;
• liwiro ndi olondola ndipo phunzirolo.

Zolakwa ndi mokoma

Mbali okha amene ayenera kuwaganizira pamaso autorefractometry ndi - ndi permeability wa kuwala diso la. Chakuti ndondomeko zikanakhala zopanda ntchito ngati pali clouding wa diso kapena mbali zina za diso. Zimenezi n'zosadabwitsa, monga muyezo waukulu - ndi mlingo wa kubweranso kwa kuwala mtengo, motero chiyero zimenezo zimadalira boma yoyamba ya chiwalo cha masomphenya.

Liwiro muyeso kuwala mtengo kubwerera zimathandiza kupeza zotsatira zolondola ndi odalirika. Pa nthawi, ndondomeko chimatengedwa ngati yolondola kwambiri mwa anthu alipo. Popeza anachitira ndi liwu monga autorefractometry icho chiri ndi mmene ntchito, mukhoza bwinobwino kupita ku phwando kuti optometrist lapansi.
