Ukukhubazeka okubonakalayo - izimbangela nokuvimbela

Inkinga yokukhubazeka okubukwayo iyinkimbinkimbi kakhulu manje. Esiklasini sokuqala, ingane ngayinye yesine inezinkinga ngokubona, eklasini lesithupha - yesithathu, kanye neziqu - njalo ngomzuzwana. Ake sibone ukuthi yiziphi izinkinga ezibonakalayo ezibonakalayo ezinganeni, kuyini isizathu salokhu, nokuthi yini engenziwa ukuze kuvinjelwe.

Ukukhubazeka okubonakalayo kwenzeka lapho, ngezinye izizathu, iso lilahlekelwa ikhono layo lokukhipha ngokwanele (ukukhanya okukhanyayo), futhi umuntu uqala ukubona izinto ziphikisiwe. Kuye ngalokhu, izinhlobo eziningi eziyinhloko zezifo ziyahlukahluka.

Ukubhekwa kwezinto eziseduze

Kulo mbono wombono , izinto kuphela ezikhona ubude bombono zibonakala ngokucacile . Futhi izifundo ezikude azikwazi ukucatshangelwa kahle, ukuhlunga kwesithombe, awunayo imingcele ecacile.

I-eyeball ezigulini eziseduze kakhulu ivame ukude ngamamitha angu-5-6 kunabantu abanobuhle. Lesi sifo senziwa ngenxa yomthwalo omude futhi ovamile emehlweni. Uma ingane ivame ukugxila ezintweni eziseduze, imisipha yamehlo isetshenziselwa futhi igaxekile kulesi sizwe. Ikhono lokuvuselela umbono wezinto ezingafani lilahlekile kakhulu.

Kunezigaba eziningana zalesi sifo:

- I-myopia engenamandla: kufika ku-3 diopters;

- I-myopia yesilinganiso: i-diopters efika ku- -6;

- I-myopia enamandla: ngaphezu kwe-6 diopters.

Isikhundla sokuzalwa esikudala sibheke ngokucacile. Lokhu kungenxa yezimpawu eziphawulekayo zesimetabolism nokuzwela kwemisipha yamehlo, eyadluliselwa kusuka esizukulwaneni kuya esizukulwaneni.

Nge-myopia, izibuko zigqokelwe ukubona izinto ezikude emgwaqweni nemininingwane encane efulethini. Uma ufunda noma ubhala izibuko kudingeka ususwe.

I-Hyperopia

Lesi simo yisimo esingaphansi kwe-myopia. Ngokubhekwa phambili, kusondelene nento, imingcele engavamile kakhulu. Ngakho-ke, izinto ezikude zibonakala ngokucacile. Futhi ngezinga elikhulu lokubhekwa phambili, izinto kuphela endaweni eqondile zibonakala ngokucacile.

Kulesi sifo, i-lens ishintshe ngendlela yokuthi ukukhanya akuphikisiwe ngokwanele, futhi kugxilwe ngaphandle kwe-retina.

I-hyperopia ihlukaniswe ngamadijithi amaningana ngendlela efanayo ne-closesightedness.

Izimbangela zokubonakala kwazo ziyizidalwa, i-eye strain, ukuvuvukala okuvamile kanye nezinguquko ezihlobene nobudala e-eyeball.

Ngokubhekwa phambili, izibuko zigqokelwe ukufundwa nokubhala, futhi kwezinye izimo azidingeki uma izinga lesi sifo kungeyona enkulu kakhulu.

I-Astigmatism

Lokhu kukhubazeka okubukwayo kubangelwa uma isimo se-cornea siphezulu siphendukekile. Khona-ke kukhona ama-radii ahlukene akhiwa kuwo, ngenxa yalokho ukukhanya okuphikisanayo ngezingxube ezahlukene. Njengoba i-astigmatism, kokubili i-myopia, i-hyperopia, nombono ovamile ziyabonwa ngesikhathi esisodwa. Kulesi simo, isiguli sibona izintambo eziningi zezinto ngesikhathi esifanayo.

Ukuhlukanisa phakathi kwe-corneal ne-lens astigmatism - kuye ngokuthi iyiphi ingxenye yeso elikhubazekile.

Ngomntwana, izibuko ezikhethekile nezilingo zikhethiwe, ezenziwe ngokucabangela ukubonakaliswa kwakhe ngabanye njenge-astigmatism.

Ngokuvamile, lesi sifo sihlotshaniswa nokuzalwa kanye nesakhiwo sokuzalwa kwesiso .

Ukuvimbela ukukhubazeka okubonakalayo ezinganeni.

Ukuvimbela ukukhubazeka okubukwayo akunzima neze. Ukuze wenze lokhu, kumele ulandele imithetho nemasu eminingana.

- Ungaqala ukuvimbela okunjalo kusukela ebusweni. Ukwenza lokhu, hlela ama-rattles ohlaza okwesibhakabhaka, ophuzi no-orange ezingeni lika-30 cm ukusuka kwamehlo omntwana. Kuyasiza futhi ukushayela ithoyizi eduze nangaphezulu kude nengane, ukuze aqeqeshe ukugxila amehlo akhe emabangeni ahlukene.

- Nciphisa i-TV nekhompyutha. Ngezimiso, isandulela esikoleni singakwazi ukuchitha isikhathi esingaphezu kwemizuzu engama-40 ngalolu suku, umfundi oyisiphakeme esikoleni esiphakeme awukho ngaphezu kwehora, kanti izingane ezineminyaka engaphezu kwengu-10 ubudala zingangehora nengxenye. Ngesikhathi esifanayo njalo emizuzwini engu-20, udinga ukwenza ama-breaks amancane ama-gymnastics ebonakalayo.
