Engari i tua atu i te mea he karu arotahi maha-arotahi anake, kāore he rārangi e kitea ana, ka taea e ngā karu arotahi whakamua te hunga whai presbyopia te kite mārama anō i ngā tawhiti katoa.
Ngā painga o ngā karāhe arotahi whakamua i runga i ngā karāhe arotahi-rua
E rua noa iho ngā mana o ngā karāhe tirohanga rua-arotahi: ko tētahi hei tiro atu i te taha o te rūma, ko tētahi hei tiro tata atu. Ko ngā mea kei waenganui, pērā i te mata rorohiko, i ngā taonga rānei kei runga i te whata o te toa hoko kai, he maha tonu te pōuriuri o ngā mea kei waenganui, pērā i te mata rorohiko, i ngā taonga rānei kei runga i te whata o te toa hoko kai, ina tirohia ngā karāhe tirohanga rua-arotahi.
Hei ngana ki te kite mārama i ngā mea i tēnei awhe "waenga", me piko ake, me titiro hoki ngā kaimau karu arotahi mā te tihi, kātahi mā te raro o ā rātou karu arotahi, kia mōhio ai ko tēhea wāhanga o te karu arotahi te mea pai ake te mahi.
He rite tonu te ahua o ngā karāhe arotahi ki te tirohanga tūturu i mua i te tīmatanga o te presbyopia. Engari ko ngā karāhe arotahi e rua anake ngā mana karāhe pērā i ngā karāhe arotahi-rua (e toru rānei, pērā i ngā karāhe arotahi-toru), ko ngā karāhe arotahi he karāhe "maha-kanohi" tūturu e whakarato ana i te ahunga whakamua maeneene, kore he raruraru o ngā mana karāhe maha mō te tirohanga mārama puta noa i te rūma, i te taha tata me ngā tawhiti katoa i waenganui.
Te tirohanga ā-taiao, kāore he "peke whakaahua"
Ko ngā rārangi e kitea ana i roto i ngā arotahi-rua me ngā arotahi-toru he wāhi e puta ai te āhua ohorere. Waihoki, nā te iti o ngā mana arotahi i roto i ngā arotahi-rua me ngā arotahi-toru, he iti te hohonutanga o tō arotahi ki ēnei arotahi. Kia mārama ai te tirohanga, me noho ngā mea i roto i tētahi whānuitanga tawhiti motuhake. Ko ngā mea kei waho o ngā tawhiti e hipokina ana e ngā mana arotahi-rua, arotahi-toru rānei, ka pōuriuri, ā, ka rerekē te mana arotahi.
Ko ngā karāhe arotahi whakamua, i tētahi atu taha, he maeneene, he kore he pakaru o te kaha o ngā karāhe arotahi kia mārama ai te tirohanga i ngā tawhiti katoa. Ka whakaratohia e ngā karāhe arotahi whakamua he hohonu ake te arotahi me te kore he "peke whakaahua".
Ka huri haere te mana o ngā karāhe arotahi whakamua i ia pūwāhi ki ia pūwāhi i runga i te mata o te karāhe arotahi, ka whakarato i te mana tika mō te kite mārama i ngā mea i te tata ki ngā tawhiti katoa.
Ka mārama te tirohanga i ngā tawhiti katoa (kaua i ngā tawhiti tirohanga e rua, e toru rānei).
Mō te tirohanga pai rawa atu, te whakamarie me te āhua pai rawa atu, ka taea e koe te whiriwhiri i ngā ara whānui ake mō te urutau māmā ake me te tere ake i te arotahi whakamua o te whakatupuranga o mua.
