Ndi zimayambitsa yochepa sightedness chiyani?

Myopia - ndi mtundu wa matenda zithunzi ntchito, zimene diso silingathe kuona zinthu pafupi ndi zinthu ili kutali ndi maphunziro amaona iye. Dzina lachiwiri la zodabwitsazi - myopia. Izi kuwonongeka zithunzi sizachilendo. Malinga ndi kafukufuku, izo zimawonedwa aliyense wokhala lachitatu la Dziko. Kodi chimayambitsa myopia? ndi limagwirira wa pakuwonekera kwake n'chiyani? Zifukwa kugona mu yochepa sightedness wa refraction osasamba kwa diso. fano aumbike Pa kupatuka si pa diso, koma kutsogolo kwa izo. Choncho, diso wayamba smudged ndipo amaona munthu amaona zinthu.

zimayambitsa

Panopa, asayansi kwaiye kusonkhanitsa chuma cha kuzipenya wa chodabwitsa osiyanasiyana monga myopia. Pa nthawi yomweyo anakwanitsa malamulo zimayambitsa myopia:

1. Kugwiritsa zithunzi katundu, zikubweretsa Usatong'olere maso ako. Izi zikhoza kuwerenga zinthu osauka kuunikira, ntchito lalitali kompyuta kapena kuonera TV nthawi yaitali.
2. Cholowa chimene chingawapangitse kukhala zidakwa. Malinga ndi kafukufuku, 50% ana omwe makolo amadwala myopia ndi zaka 18 ali zimasonyeza amaona masomphenya. Ngati myopia anali kholo limodzi lokha, kuchuluka akutsikira 20-25%. Ngati makolo ali ndi masomphenya wabwinobwino, ana amadwala myopia% 8 okha milandu. kuzipenya Zimenezi zinachititsa kuti mapeto kuti chibadwa mwina ndi mbali ya zimayambitsa yochepa sightedness.
3. Hemodynamic chisokonezo - kuchepa magazi kuwonjezera ziwalo masomphenya, osauka magazi aziyenda bwino mu nembanemba lamkati la maso, kuphwanya kwa yozungulira ndi pakati otaya magazi.
4. Akamakonda zakudya. Pakuti yachibadwa diso minofu synthesizing muyenera kudya zonse kufufuza zinthu zothandiza monga nthaka, mkuwa, chrome. akusowa angathe kuonedwa monga chifukwa cha myopia.

kumvetsa sayansi myopia

Masomphenya kotheka, diso la munthu analanda cheza kuwala anasonyeza ku zinthu zosiyanasiyana ozungulira. Mkati diso ali refracted m'njira monga kuganizira diso chifaniziro cha mfundo yabwino. cheza kuwala akuchokera zinthu kutali pafupifupi kufanana malangizo. Pamene myopia diso lili miyeso anasintha ndi njira cheza zimenezi ndi kupotoza. fano aumbike kutsogolo kwa diso. Kunyezimira kwa zinthu yapafupi ndi kusiyana kwa malangizo kuyenda. Iwo ankachitira diso yachibadwa.

"Monga chitonthozo, wokhala ..."

Asayansi ena amakhulupirira kuti yochepa sightedness - ndi zosinthika zamoyo kugwira ntchito bwinobwino m'dzikoli zikhalidwe za likuwonjezekabe mavuto ziwalo masomphenya. Maso atengere ntchito pa zosiyanasiyana pafupi pa voteji osachepera. Ndipo ichi ndi chifukwa choyembekezera zabwino, sichoncho? Awa ndi malingaliro za chofunikira ndi maganizo zikuluzikulu zimene zimayambitsa myopia.
