Kuremara wezvakaonekwa. Mushonga urema

Kuremara chiratidzo - chii ichi? Mhinduro yomubvunzo uyu, uchadzidza kubva kukurukurwa munyaya. Uyezve, muchapiwa ruzivo pamusoro sei, chii matambudziko ziso vanhu vanosangana kazhinji, uye sei unogona kubvisa navo.

Vhuṱanzi

In okurapa, kazhinji kunzi kuremara kukanganisa refraction. anomalies kwakadaro - rakajairika matambudziko ziso. Musimboti boka iri zvirwere ndechokuti ari Manyiminya hurongwa ziso haakwanisi kutarisa chiedza mwaranzi pamusoro the retina, inova yedu Registrar chiedza kuitika. Huru chiratidzo uye migumisiro ichi pathological ezvinhu ari murombo chiratidzo.

Vision kuremara uye ayo mamiriro

kutsauka Izvi zvinogona kuva yakasiyana hunhu. wandei zvakajairika zvikanganiso nhasi inomira panze, zvinoti:

• astigmatism;
• nearsightedness kana myopia atumidzwa;
• Kuona zviri mberi kana hyperopia;
• ruvara upofu kana ruvara upofu;
• ruvara agnosia.

Kuti unzwisise chikonzero nei paine imwe chiratidzo kuremara vanofanira kufunga unhu akauya zvarakasiya zvizere.

astigmatism

Chikonzero kukura pathological ezvinhu kwakadaro zvisiri zvakaumbwa cornea optic muviri. Zvinofanira kucherechedzwa kuti kukura astigmatism zvakananga kunokanganisa ziso izvo misha hama kuti akabatana kuti refraction. Vose ataurwa zvikonzero kunotoreva kusiyana marefu kuti zvinokosha pfungwa "mifananidzo".

kuremara akadaro nechaanoona muziso rimwe anogona nokubatanidza zvinokonzerwa hyperopia, myopia uye zvakajairika chiratidzo.

Myopia, kana inonzi myopia

Nearsightedness anogona kuitika nokuda kwezvikonzero zvinoverengeka. Chokutanga kuwedzera ziso, apo kuramba zvakarurama indekisi. Kana chikonzero chechipiri, zvinondiremera simba Manyiminya refraction rinopfuura 60 diopters, apo nokureba optic nomuviri inowanzotorwa siyana. Vose vakapa zvarakasiya kukanganisa negashiro inowanzotorwa mufananidzo. Nemamwe mashoko, mufananidzo hakusi kugona kuisa pfungwa the retina, uye riri mukati yeziso. Saka the retina anowana chete kwawakananga mufananidzo upi zvinhu vari chinhambwe kubva kumunhu.

Kururamisa kuremara ichi nechaanoona, varwere kazhinji mishonga magirazi inokosha kubatsira kuvaka mufananidzo zvakarurama. Muchiitiko chino, munhu anogona kunzi zvinhu kure pasina munomimina. To myopic murwere kuonekwa zvakajeka, kushandisa kubvisa lenses izvo kuunza zvinhu kure.

Kuona zviri mberi, kana hyperopia

kuremara kwakadaro anova wakakodzera kuti zvakanyanyisa simba Manyiminya refraction ari ziso zvomukati apo kuchengetedza dzose urefu yeziso. Zvinofanira kucherechedzwa kuti chikonzero hyperopia uye kupfupikisa anova pasi yeziso ndichengetedze refractive simba.

Nokuti hyperopic ziso haasi kukwanisa kuumba rainyanya kukosha pamusoro the retina, tsandanyama Makakatanwa inowedzera yekudyidzana. Fani iyi zvishoma nezvishoma kuchinja curvature pamusoro izvo, izvo zvinozoita kunotungamirira kuti kwadzakabva ari kutarisana nhengo pasi yemamiriro ezvinhu. Zvisinei, izvi hazvina kukwana kuti chakaipa chinangwa chacho.

Pamunenge muchikurukura zvinhu pedyo ziso, tsandanyama rinenge muviri kutorarama kunyange zvakawanda. Mune mamwe manzwi, pedyo chinhu, ndipo zvinoratidzika pamusoro the retina mufananidzo.

Ndedzipi nzira yokubvisa zvinhu kuremara, kana zviri,-refu kwehurumende? Kuti agadzirise yakatsauka kubva ndinoiitawo kushandiswa magirazi pamwe lenses akadaro. Vanobatsira mukuvaka zvakakwana mufananidzo wakanaka.

Sezvaunoziva, panguva pakaberekwa mwana, maziso ake compressed yakatambarara zvishoma. Ndokusaka zvose vaduku zvimwe Kuona zviri mberi. Zvisinei, kukura kwacho zvaakaratidzwa kwavo zvishoma nezvishoma kudzoka dzose.

Kana mwero Kuona zviri mberi kwevanhu diki, kure uye pedo zvakaratidzwa zvive zvakajairika. Asi panguva imwe chete vanhu vachange chokunyunyuta chakakomba nomusoro uye ziso kuneta. Kana avhareji mwero Kuona zviri mberi, zvinoita sokuti murombo pedo chiratidzo.

Color upofu, kana ruvara upofu

kuremara akadaro ari chirwere vachiberekwa, kunoitika kakawanda muvarume. Musimboti kutsauka uyu kuti varwere anetseka zvakarurama ruvara maonero, chinjika photoreceptor masero (pasikweya) muziso the retina. Kana dzimwe mhando pasikweya muvanhu hazvina kukwana, saka aripo ruvara upofu.

ruvara agnosia

Color agnosia - imwe mhando ndezvimwe zvokutsauka akadai kutarisana agnosia. Kana vakadaro chirwere kushivirira ruvara chiono sanganisika varege kusiyanisa mavara. Panewo mawa uye tsamba agnosia. Chirwere pamusoro abnormalities izvi zvinoda unyatsoongorora pedyo wetsinga. Kuona mhando agnosia zvinogoneka pachishandiswa anokosha nemiedzo.

Kurapa chirwere ichi chiri yezviri kurapa ndezvimwe zvokutsauka, izvo zvakazoita kuti kukundwa nomumwe pfungwa zvikamu. Kakawanda agnosia haigoni murapwe vachiuya guru kusagadzikana kumurwere.

urema zvakafanana nezvaiitwa vamwe dzekare migraine

Migraine pamwe chaiwo Aura zvikuru nevakawanda vanhurume. Muchiitiko chino, varwere vanogona zvinhu vachivavhiringidza. Kunowanzosanganisira kuonekwa sezvo kupenya pfungwa molniepodobnyh kupenya, zigzags, balls, uye ipapo yakatanga rakanaka simba nomusoro. Kuwanda mananara aya kwakacherechedzwa kwemaminitsi kana masekondi mashoma. Kazhinji, mifananidzo inotsiviwa ikapenya akafirwa zvimwe zvikamu zviri kutarisana munda. Zvinofanira kucherechedzwa kuti kutyorwa yakadaro nguva pamwe chete chiveve chiso, hafu muviri uye mutauro, uyewo neutera maoko nemakumbo uye kutyora kwomuzvarirwo kutaura.
