Whakarāpopototia te tuhinga:  Hong Kong (CNN) Ehara ko Āhia anake. I te ao katoa, kei te kaha haere te matapo o te katoa. Ko te matakite tata, ko te matakite poto, ko te tikanga he mārama te kite i ngā ahanoa tata, engari he pōhēhē te kite i ngā mea tawhiti atu. E ai ki ngā kairangahau, kua rua, kua toru noa iho rānei te tokomaha o te hunga matapo i te nuinga o Ahia ki te Rāwhiti i roto i ngā tau e 40 kua hipa. He maha ngā wāhi pērā i Hong Kong, Singapore me Taiwan he ōrautanga i te 80%. I Korea ki te Tonga, kua piki ake te tatauranga o te matakite i waenga i te hunga 20 tau te pakeke mai i te 18% i te tau 1955 ki te neke atu i te 96% i te tau 2011. He take ao whānui tēnei -- kei te piki haere hoki ngā tatauranga o te pōhēhē i ngā whenua o te Uru pērā i Tiamana me Te Hononga o Amerika. "Kia tata ki te 40% i te U.S., i whakaritea ki te 25% i nga tau 1970," e ai ki a Dr. Michael Chiang, kaikorero mo te whare wananga o te American Academy of Ophthalmology. Engari e kii ana nga kairangahau he ngawari, he koreutu, he waatea hoki te whakaiti i te tupono o te myopia: Haere ki te ra. Heoi, i ētahi wā, ko ngā rongoā māmā rawa te mea uaua rawa ki te whakatinana. Ko te pakarutanga o te myopia i waenganui i nga Āhia ki te Rāwhiti kua whakaoho i ngā pātai ahurea e pā ana ki te take i nui ai te hunga taitamariki ki te whakawhanake i ngā raruraru tirohanga. Kua roa e whakapono ana te tokomaha, ko te pānui, te ako, te mātakitaki rānei i tō waea pūkoro, ka pā mai te tirohanga poto. A, ko te amuamu noa iho, he nui rawa te wā e noho ana te hunga rangatahi ki o rātau mata. Engari kei te arotahi nga kairangahau ki tetahi take rereke. "Ki te nui te haere o nga tamariki ki waho, kaore he aha te nui o te ako e mahia ana e ratou. Kāore rātou e pōuri", te kī a Ian Morgan, he kairangahau i te Australian National University. E mea ana ngā kairangahau me whiwhi ngā tamariki me ngā taiohi i te marama o te rā i ngā tau whakahirahira o to rātau whanaketanga i te wā e tipu tonu ana ō rātau karu kanohi. Kāore i te mārama te āhua o te whakamarumaru o te marama ki o rātau kanohi. Ko tētahi ariā e whakaaro ana ka whakaoho te rā i te tukunga o te dopamine i roto i te retina; ko tētahi atu e whakaaro ana ka tiakina te marama puru mai i te rā i te mate. He māmā te otinga. Kia nui ake te wā e noho ana ngā tamariki ki waho, kia iti ake ngā tono (mai) i ngā kura, kia okioki anō hoki", e ai ki a Seang Mei Saw, he kaiwhakaako i te mātauranga mate uruta i te National...
Kei te piki haere te tatauranga o te myopia i Ahia ki te Rāwhiti, e pāngia ana te 80-90% o te taupori pakeke. Ko te taunakitanga kei te piki haere nga tatauranga o te myopia i Uropi me te U.S. He tohutohu a ngā pūtaiao ki ngā tamariki: haere ki waho ki te tākaro.
