The convergence ziso: a tsananguro. Tinoona sei? ziso basa

Convergence ziso rutapudzo riri kutarisana namasanhu panguva Kuda kutamba uri pedyo chinhu. Panguva iyi nhete mboni. The convergence ziso dzepanguva kunoitika apo binocular chiratidzo. kushaikwa kwayo chinokurwadzai yakashatiswa mumufambiro strabismus.

Basa ziso convergence

The convergence ziso inoita basa rinokosha binocular zvaakaratidzwa, apo tichibatanidza monocular Mifananidzo, ndinosika anodiwa ezvinhu nokuda kwemapazi kwavo. In vana, kazhinji chibharo.

Zvirwere convergence kunotungamirira chitarisiko uye zvibereko myopia, axial myopia kukura. Chiitiko zvokuva uye pamamiriro, kunyanya vana vavo vabereki. Kuti aite izvi, kuti atakure chirwere ziso convergence. How kuongorora?

1. Vanhu vakuru vanofanira kuisa mwana kutarisana naye, vanza ziso rimwe pacharo.
2. Around pakati daro kuisa penzura vertically nenzira yakadaro kuti akura ziso rakavhurika vakamuona kushandisa hafu mwana paanoputsikirwa, uye okumusoro kuguma papi pa ziso pamwero.
3. Kurudzira mwana wako kuti kutarisa vakuru ziso rakavhurika uye ona kuti nepenzura mazhinji anoona panguva imwe chete.
4. Kana mwana anoona "mumwe" rutanda, izvi yaguma. Aputsa binocular chiratidzo.
5. Kana "mbiri" pakati penzura, unofanira kuti kutarisa chete panguva pamusoro chinhu kuti zvishoma nezvishoma kuuya pechiso chomwana.
6. Kana pasina convergence, sezvo convergence munhu penzura ine munhu mwana ziso vanopfuura munhu anotarisira mhuno, wechipiri - kutemberi.
7. Kana paine convergence meso nomwana vari symmetrically pivoted kuti mhuno, apo daro ipfupi kusvika 5 cm.
8. Zvadaro kumbirai mwana wako kutarisa penzura maminitsi 1-1.5. Kana convergence weziso akatsiga, vanofanira zvakaenzana vakatendeukira mhino.
9. Suggest mwana wako pasina penzura pfungwa maziso zvose mhino. Kana zvinoitika kuti "nharo convergence."

Treatment convergence kutyorwa

Kana pasina convergence ziso, zvinokosha kuita kuchirapa muviri zuva nezuva:

• Set ari chinhambwe 30 CM penzura uye vachitarira apfuura naye. Izvi zvinofanira kuonekwa mifananidzo sezvo anenge maviri chinhu.
• First unofanira kutarisa mufananidzo "kodzero" ane penzura, kuti vaonekwe uye "vakasara", ipapo uchatamisa Kutarira "kuruboshwe", pasina usakanganwa mumwe.
• Kuda kutamba kwakadaro kuramba kuita zvimwe, kutanga zvishoma nezvishoma uye panguva imwe kuwedzera kumhanya.

Kuti chiwedzere convergence kuti aishanda kurovedza kuita mazuva ose. Zvavakanga inogona alternated masikati.

Exercise 1. Place penzura vertically dzimwe masendimita 20 kubva ziso, mumasekonzi 20 kutarisa kure kure, kugadzirira pfungwa kaviri mufananidzo chinhu, izvozvo anotarira penzura uye kuzvitarisa kuti 5 masekonzi, ipapo zvakare tarisa kure uye kudzokorora chiito.

Exercise 2. Ronga vertically penzura pa zvombo urefu, zvishoma nezvishoma kufamba akananga maziso ake pamberi slitting, uye zvishoma nezvishoma ndiribvise pacharo.

Exercise 3 anoshanda panguva nesarudzo convergence. Mirai akatarisa nepahwindo kuti vaonekwe jengachenga. Force kuchaderedza ziso kumhino, vakabata munzvimbo 7 masekonzi, ipapo kuderedza maonero kure uye ziso zvakare.

Nemamiriro womunhu ziso

Vanopfuura 80% mashoko vanhu kuwana kuburikidza chii uye sei tichiona. The nemamiriro optic muviri zvikuru kunzwisisa. It kunobva ziso mabasa.

Apple ziso romunhu chinhu rinosvika mugari chimiro. It riri mukati dehenya kutenderera. Kubva pakuzvarwa kusvikira pakufa, ziso nezvigadziko kaviri.

An nzvimbo inokosha inogarwa iri optic etsinga. It transmits ruzivo kune occipital cortex, uye ipapo vakaongorora.

Nokuda lacrimal shwanu pose ziso inoramba nyoro. Misodzi zvakanaka lubricated conjunctiva.

The nemamiriro ziso kwevanhu yeziso tsandanyama dzakasimba kuita pamwe chete. The lids kufukidza ziso, kudzivirira kunaka zvikonzero pamusoro. A yakafanana basa rinoitwa ne eyelashes.

The ukama mamiriro uye kushanda meso

Kuti tinzwisise nemamiriro kuona nhengo inofanira kuzvifananidza pamwe kamera. Zvinoita chifananidzo nokuita pfungwa panyaya yako uye kubvumira mumwe yakawanda chiedza apfuure diaphragm.

Kana danda anopinda ziso, chobudira kuburikidza cornea, izvo zvinoitwa 75% chiedza kutaura. Zvadaro anoenda mboni, apo mari iri kugadziridzwa.

Gogorosi - wechipiri izvo maziso. Maumbirwe Its zvichisiyana chete voltage kana tsandanyama kuzvivaraidza. Chiedza kwawakananga anosvika the retina, izvo kuva tsinga nomunhu. Paaizosvika mufananidzo uropi rinonyanya mukana kunakirwa nyika, tarisa mavara uye zvinhu. Nemamwe mashoko, zvose tinoona muupenyu chaihwo.

The mamiriro unoratidza kuoma ziso. Nyanzvi achiri havagoni kuwana nzira ndinobvisa tsandanyama yeziso, nokuti optic etsinga inonyatsoziva chaizvo.

nechepakati chiratidzo

Yakasvika zita raro nokuti inopa nechepakati chikamu the retina uye nechepakati fossa. chiratidzo ichi kunoita munhu kusiyanisa zvitarisiko uye zvidiki zvinhu.

Kunyange kana ikawira zvishoma, murume kamwe rova kuchioneka.

The chikuru hunhu nechepakati chiratidzo acuity iri. kudzidza Its kunokosha kuongorora kutarisana nevanhu midziyo seboka, kuti chamber zvakasiyana-siyana pathological kwendangariro.

Visual acuity - nekugona ziso kuona mbiri pfungwa, izvo dziri pedyo nepedyo, pane imwe kure.

Uyewo, pane pfungwa maonero yorusvingo rinomirira pakona riri kuumbwa pakati ehomwe chinhu pasi ongororo uye nodal pfungwa yacho optic muviri.

peripheral chiratidzo

Pamusana kwaari, vanhu vanogona dzokumabvazuva vakazvipfigiramo nzvimbo uye kuona murima.

Zvakakodzera kutsausa musoro kurudyi uye kubata meso chero nyaya, ngazviitwe mufananidzo pamusoro porusvingo, uye kugadzira munotarira vamwe zvinhu zvayo. Kana unogona kuona zvakanaka, izvozvo rinotaura nechepakati chiratidzo. Zvisinei, kunze chinhu ichi mu munda maonero mapopoma uye zvimwe zvinhu zvikuru. Somuenzaniso, mukova kukamuri, wenguvo, imbwa agere parutivi pasi. Zvinhu izvi zviri pachena kuoneka, asi pamberi, uye zvinokwanisika kuti andobata inofamba. Ichi chiono peripheral.

maziso evanhu, kwete kutamira, anogona kufukidza 180 inosiyana pajengachenga uye zvishoma shoma (anenge ¹³⁰⁾ muna hunyambiri Meridian.

The tinoshandisa nechepakati Chiono zvikuru tichienzanisa peripheral. Izvi imhaka yokuti nhamba pasikweya kubva pakati kusvika peripheral zvikamu the retina huduku zvikuru.

Chii anonzi romuzvarirwo chiratidzo

chiono Normal kwevanhu nokuda refraction chechiedza danda muziso, kwete yakatsauka kubva kwose kwose. Nokudaro, izvo, kurutivi cornea, kuti izvo zvinoparadzira mufananidzo mufananidzo pamusoro the retina panguva macula.

Mumwe munhu ane ake wenguva chiratidzo. It kunotemwa nezviri yorudzii nzvimbo murwere anoona patafura Golovin-Sivtseva. Anozivikanwa chikwata zvinoreva kuti inoti 10 mutsetse. Zvinoitika chiratidzo.

zvaipesana refraction

Refraction anonzi refraction chiedza muziso.

Kana danda riri refracted nemazvo, mufananidzo achingoraramira chaiyo pamusoro the retina. Nevakomana mamiriro (refractive kukanganisa) chinokurwadzai kugadzirwa uye kwaita hyperopia uye myopia. Kana mufananidzo sokuti avhiringidzwa, miviri. Pakururamisa rakaiswa wezvokurapa magirazi uye lenses anokonzera chiedza danda kutarisa the retina.
