Abana mubyukuri bareba kure, kandi uko bakura amaso yabo nayo arakura kugeza bageze aho "batunganye", bita emmetropia.
Ntabwo byakozwe neza byerekana ijisho ko igihe kigeze cyo guhagarika gukura, ariko tuzi ko mubana benshi ijisho rikomeza gukura emmetropiya yashize hanyuma bakareba kure.
Ahanini, iyo ijisho rimaze gukura cyane urumuri rwimbere rwijisho ruza kwibanda imbere ya retina aho kuba kuri retina, bigatera kutabona neza, bityo rero tugomba kwambara ibirahure kugirango duhindure optique hanyuma twongere twerekeze kuri retina.
Iyo dusaza, duhura nuburyo butandukanye. Uturemangingo twacu turakomera kandi lens ntishobora guhinduka kuburyo bworoshye kuburyo dutangira gutakaza hafi yicyerekezo.
Benshi mubantu bakuze bagomba kwambara bifocal ifite lens ebyiri zitandukanye-imwe kugirango ikosore kubibazo bifite iyerekwa ryegereye hamwe nimwe ikosora kubibazo bifite icyerekezo kure.
Muri iki gihe, abana barenga kimwe cya kabiri cy’abana n’ingimbi mu Bushinwa ntibareba kure, nk’uko ubushakashatsi bwakozwe n’inzego nkuru za leta bwabisabye ko hashyirwa ingufu mu gukumira no kurwanya iki kibazo. Niba ugenda mumihanda y'Ubushinwa uyumunsi, uzahita ubona ko urubyiruko rwinshi rwambara ibirahure.
Nibibazo byabashinwa gusa?
Nta nkeka. Ubwiyongere bwa myopiya ntabwo ari ikibazo cyabashinwa gusa, ahubwo nikibazo cyane cyane muri Aziya yuburasirazuba. Nk’uko ubushakashatsi bwasohotse mu kinyamakuru cy’ubuvuzi cya Lancet mu 2012 bubitangaza, Koreya yepfo iyoboye iyo paki, aho 96% by’abakiri bato bakuze bafite myopiya; kandi igipimo cya Seoul kirarenze. Muri Singapuru, imibare ni 82%.
Nintandaro yiki kibazo rusange?
Ibintu byinshi bifitanye isano nigipimo kinini cyo kureba kure; kandi ibibazo bitatu byambere biboneka kubura imyitozo ngororamubiri yo hanze, kubura ibitotsi bihagije kubera imirimo irenze amasomo ndetse no gukoresha cyane ibikoresho bya elegitoroniki.
