Mu by’ukuri abana baba bafite ubushobozi bwo kureba kure, kandi uko bakura amaso yabo na yo arakura kugeza igihe bageze ku rwego rwo kureba neza, rwitwa emmetropia.
Ntabwo biramenyekana neza icyaba gitanga ikimenyetso cy'uko igihe kigeze cyo kureka gukura, ariko tuzi ko ku bana benshi ijisho rikomeza gukura rigahita rirenga emmetropia maze rigahita ribona hafi.
Muri make, iyo ijisho rimaze igihe kirekire cyane, urumuri ruri imbere mu jisho ruhita rugaragara imbere ya retina aho kuba kuri retina, bigatuma tutabona neza, bityo tugomba kwambara indorerwamo kugira ngo duhindure optique hanyuma twongere dushyire urumuri kuri retina.
Iyo dusaza, duhura n'ikibazo gitandukanye. Ingirabuzima fatizo zacu zirushaho gukomera kandi indorerwamo ntizihinduka byoroshye bityo dutangira no guta ubushobozi bwo kureba hafi y'amaso.
Abantu benshi bakuze bagomba kwambara amabara abiri afite indorerwamo ebyiri zitandukanye - imwe yo gukosora ibibazo byo kureba hafi n'indi yo gukosora ibibazo byo kureba kure.
Muri iki gihe, abana n'ingimbi barenga kimwe cya kabiri mu Bushinwa ntibareba hafi, nk'uko ubushakashatsi bwakozwe n'inzego zikomeye za leta bubigaragaza, bwasabye ko hashyirwaho imbaraga zo gukumira no kugenzura iki kibazo. Nugenda mu mihanda yo mu Bushinwa uyu munsi, uzabona vuba ko urubyiruko rwinshi rwambara indorerwamo.
Ese ni ikibazo cy'Abashinwa gusa?
Oya rwose. Gukwirakwira kw'indwara ya myopia si ikibazo cy'Ubushinwa gusa, ahubwo ni ikibazo cy'Aziya y'Iburasirazuba cyane cyane iyo muri Aziya. Nk'uko ubushakashatsi bwasohotse mu kinyamakuru The Lancet mu 2012 bubivuga, Koreya y'Epfo iza imbere mu itsinda, aho 96% by'urubyiruko rufite myopia; kandi igipimo cya Seoul kiri hejuru kurushaho. Muri Singapuru, imibare ni 82%.
Ni iyihe mpamvu nyamukuru y'iki kibazo rusange?
Hari ibintu byinshi bifitanye isano n’umuvuduko munini w’indwara yo kutareba hafi; naho ibibazo bitatu bya mbere ni ukudakora imyitozo ngororamubiri yo hanze, kubura ibitotsi bihagije bitewe n’akazi kenshi gakorerwa hanze y’akazi no gukoresha cyane ibikoresho by’ikoranabuhanga.
