He tirohanga tawhiti ngā pēpi, ā, i a rātou e pakeke haere ana, ka tipu haere hoki ō rātou kanohi kia tae rā anō ki te wāhi "tino pai" o te tirohanga, e kiia nei ko te emmetropia.
Kāore anō kia tino mārama te tohu o te kanohi kua tae ki te wā kia mutu te tipu, engari e mōhio ana tātou he maha ngā tamariki kei te tipu tonu te kanohi tae noa ki te emmetropia, ā, ka tata te kite.
Ko te tikanga, ina roa rawa te kanohi, ka arotahi te mārama i roto i te kanohi ki mua i te retina, kaua ki te retina, ka pōuri te tirohanga, nō reira me mau mōhiti hei whakarerekē i te tirohanga, hei arotahi anō i te mārama ki te retina.
Ina kaumātuatia tātou, ka rerekē te tukanga e pāngia ai tātou. Ka pakari haere ō tātou kiko, ā, kāore e ngāwari te urutau o te karu arotahi, nō reira ka tīmata te ngaro o te tirohanga tata.
He maha ngā kaumātua me mau i ngā karuārahi kanohi rua, he karuārahi e rua ngā momo karuārahi—ko tētahi hei whakatika i ngā raruraru o te tirohanga tata, ko tētahi hei whakatika i ngā raruraru o te tirohanga tawhiti.
I ēnei rā, e ai ki tētahi rangahau a ngā tari kāwanatanga matua, neke atu i te haurua o ngā tamariki me ngā taiohi i Haina he kanohi tata, i karangahia kia kaha ake ngā mahi hei ārai me te whakahaere i te mate. Ki te hikoi koe i ngā tiriti o Haina i ēnei rā, ka kite wawe koe ko te nuinga o ngā taiohi he mau mōhiti.
He raruraru Hainamana anake?
Kāore rawa. Ehara i te mea he raruraru Hainamana anake te pikinga o te horapa o te mate kanohi pōuri, engari he raruraru nui nō Āhia ki te Rawhiti. E ai ki tētahi rangahau i whakaputaina ki te hautaka hauora The Lancet i te tau 2012, ko Kōrea ki te Tonga te kaiārahi, me te 96% o ngā taiohi e pāngia ana e te mate kanohi pōuri; ā, he nui ake te reiti mō Seoul. I Singapore, ko te whika he 82%.
He aha te pūtake o tēnei raruraru whānui?
He maha ngā āhuatanga e pā ana ki te nui o te tirohanga tata; ā, ko ngā raru matua e toru ko te kore o te mahi ā-tinana o waho, te kore moe e ranea nā te taumaha o ngā mahi i waho o te kura, me te whakamahi nui i ngā hua hiko.
