Magalasi ndi mabowo - tingayembekezere zinawakhudza motani?

magalasi Pinhole, kapena magalasi ndi mabowo, monga mwa opanga ndinu mphunzitsi kuti tikonzedwe masomphenya. Iye akhoza kusintha ndi myopia ndi hyperopia. Opanga komanso kulonjeza masomphenya bwino ndi astigmatism ndi asthenopia (diso kutopa, aakulu).

Patali (myopia) akupezeka munthu pamene mapindikidwe wa mwana wa diso, imene cheza kuwala si lolunjika pa diso, koma kutsogolo kwa izo. Chifukwa zodabwitsazi - kufooka minofu diso, yomwe kugwira apulo. Hyperopia - ndi chodabwitsa imene fano aumbike za nzika diso. Nthawi zambiri, m'badwo zokhudzana kusintha. Astigmatism - ndi zovuta zithunzi kuwonongeka, amene amachepetsa acuity zooneka mtunda ndi pafupi.

Magalasi ndi mabowo ali magalasi choyamba pamaso koma m'malo magalasi iwo mbale ndi mabowo ting'onoting'ono. Opanga amanena kuti ndi chitukuko atsopano, kukhazikika pa maziko a malamulo a sayansi kuwala (refraction, defragmentation, kulowerera wowala kamwazi). Kwa anthu odziwa sayansi ndi mankhwala, zochitika enawa chachinsinsi ndipo si bwino kwambiri. Koma wofufuza tsatanetsatane, palibe amene amapereka. Mfundo opaleshoni ya mfundo zimenezi zachokera chinthu defragmentation chodabwitsa pamene kukula mozama za kuthengo, chifukwa chimene fano lolunjika chimodzimodzi pa diso, ndi masomphenya bwino. Koma chodabwitsa amadziwika kuti kabowo zotsatira ( "peeping mdzenje"). Komanso, yafupika zimakhudzanso minofu diso, zomwe zimalimbikitsa zosangalatsa awo.

Opanga kulonjeza kuti magalasi ndi mabowo pa mwambo yeniyeni malangizo ndiponso kuwagwiritsa ntchito kwa mphindi zosachepera 30 tsiku amatha kubwerera kwathunthu masomphenya chabe chaka. Iwo akulangizidwa kuyamba ndi mphindi 10. Kwa nthawi yoyamba munthu amakhala kusapeza, koma azolowere pa nthawi. Mu magalasi awa mungathe kuwerenga, kuonera TV, ntchito pa kompyuta, kuchita ntchito zina.

Pali view wina. Akatswiri ambiri amakhulupirira kuti magalasi ndi mabowo - achabechabe chida. Popeza myopia pafupifupi sizingasinthe palokha, ndiko kuti, popanda chopinga kunja, ndi kulimbitsa thupi sangathe kuchotsa za izo, inu mukhoza kusiya kokha imfa ya masomphenya. Hyperopia N'chapafupi kupewa diso kuona mode, ndi kuchita Zochita wapadera kuti maso. Astigmatism - zambiri kobadwa nako chilema maganizo, mukhoza kuchotsa, koma pa myopia chomwecho Zatsala ndi mankhwalawa kwa iye.

phunziro American, mfundo cheke ndi mabowo anapanga mu United States, zasonyeza kuti chipangizo ichi sangagwirenso ntchito iliyonse. Iwo umachita masomphenya sizolondola. Komanso, monga kunapezeka, ichi si chitukuko chamakono. zipangizo zofanana wakhalapo mu Ages Middle. Koma ndi mbale perforated pa nthawi m'malo ndi mandala, amene zambiri yabwino, ndipo amapindula kwambiri.

Kotero kuti ngakhale mfundo mdzenje ndi kuyang'ana zachilendo kwambiri ndi looneka kulonjeza chozizwitsa mankhwala, ndi bwino kuganizira mmene chozizwitsa rationally. Osati zonse limapezeka mu kulengeza monga umisiri kudula-m'mphepete, iwo ali.
