Me pēhea tāu tirohanga ki te ao? Me pēhea tāu mōhio ki ngā tāngata e karapoti ana i a koe, ki ngā taonga o tō taiao, me ngā tae ataahua o te taiao? Kei roto i te tukanga mahi tahi whakamiharo i waenganui i ō kanohi utu nui me tō roro te mea ngaro, e mōhiotia ana ko te "tirohanga". He nui atu tēnei i te "kite" noa iho; he mahi tino uaua, he mahi nui hoki. I tēnei rā, me wehewehe tātou me pēhea te mahi a te tirohanga i roto i tētahi huarahi māmā, ngāwari ki te mārama.
He aha te Matakite? He māmā noa iho...
I roto i ngā kupu māmā noa iho, ko te tirohanga te tukanga e mahi tahi ai ō kanohi me tō roro ki te tango i te mārama e whakaata ana i te ao e karapoti ana i a koe, kia puta ai he ahua whai tikanga. Ko tētahi o ō kare ā-roto matua e rima. Mō te nuinga o tātou, ko tō tātou māramatanga katoa ki te ao ka hangaia e tō tātou tirohanga. Whakaarohia te rerekētanga o tō oranga me te kore he tirohanga!
He aha te mahi a ō kanohi? He tikanga whakamiharo!
Ka tīmata te tukanga tirohanga ina kitea e ō kanohi te mārama, ka hurihia hei tohu io. Kātahi ka haere ēnei tohu mā roto i ō io whatu ki tō roro. Ko tō roro te kaiwhakamāori matua; ka whiwhi ia i ēnei tohu, ka tukatuka, ka hanga i te ahua e kite ana koe. Tata tonu te puta o tēnei, he maha ngā wā i ia hēkona.
He rite tonu ō kanohi ki te kāmera?
Ae, he maha ngā wā ka whakaritea e tātou ngā kanohi ki ngā kāmera. Heoi, ko te ritenga kē tēnei: I hangaia ngā kāmera mā te whai i te hangarau o te kanohi tangata.
Whakaarohia te mahi a te kāmera. He karu arotahi tōna e kohikohi ana i te mārama, ka tuku atu ki tētahi pūoko motuhake. Ka hurihia e taua pūoko te mārama hei tohu hiko, ka tukatukahia e te rorohiko iti i roto i te kāmera hei pikitia. Ka taea e koe te whakarite i te arotahi me te whakahaere i te nui o te mārama e tomo ana ki te kāmera.
He karāhe anō hoki ō kanohi. Ka kohia e ēnei te māramatanga ka arotahi ki tētahi hanganga e kiia nei ko te retina . He rite te mahi a te retina ki tētahi pūoko kāmera, engari he tino matatau ake, he uaua ake hoki. Ka hurihia e te retina te māramatanga e tae mai ana hei tohu io, ka tukuna atu ki te roro.
Pērā i te kāmera, ka mahi aunoa ō kanohi i ngā mahi pēnei i te arotahi me te whakahaere i te mārama. Ka whānui, ka whakawhāiti rānei ō kamo hei whakahaere i te nui o te mārama e tomo ana ki te kanohi. I taua wā, ka whakarerekē ngā uaua o roto i tō kanohi i te āhua o te karu arotahi kia mārama ai tō arotahi ki ngā mea i ngā tawhiti rerekē.
He aha te retina, ā, me pēhea tana mahi?
He paparanga kiko tino motuhake tō retina , he tino tairongo. Kei roto ngā pūtau e kiia nei ko ngā kaiwhakawhiwhi whakaahua , ko tōna tikanga ko "ngā pūtau whiwhi māramatanga." Ina pā te mārama ki ēnei pūtau, ka puta ngā tauhohenga matū me ngā tauhohenga hiko. Koinei te huarahi e whakauru ai ngā pūtau i te māramatanga ki ngā tohu io.
E rua ngā momo matua o ngā kaiwhakarongo whakaahua:
- Ngā tokotoko: Ko ēnei te kawenga matua mō te kite i ngā rerekētanga o te kanapa o te mārama. Mā ēnei koe e āwhina ki te kite i ngā āhuatanga pōuri, iti rānei.
- Ngā Kone: He tairongo ake ēnei, ā, he kawenga mō te kite i ngā taipitopito pai me te kite i ngā tae rerekē.
Kia hurihia te mārama hei tohu io, ka tukuna e te retina ki ō io whatu .
Te tūranga o ngā io whatu
He rite te mahi a ō io whatu ki ngā taura raraunga tere-tere. Ka haria e rātou ngā tohu mai i te retina ki ngā wāhanga rerekē o te roro. Ka haere ēnei tohu i roto i ngā io whatu ki te tae atu ki ngā pokapū tukatuka tirohanga, ko rātou te kawenga mō te wetewete me te whakamaori i tāu e titiro ana.
Ko te roro te kaiwhakatau whakamutunga!
Ko te taahiraa whakamutunga, ko te taahiraa tino nui hoki, ka puta i roto i tō roro. Ka whiwhi ia i ngā tohu kua whakakōrerotia, ka wetewete i aua tohu, ā, ka whakamahi i aua mōhiohio hei hanga i tētahi ahua mārama mai i te urunga o ngā kanohi e rua.
Whakaarohia: i a koe e pānui ana i tēnei rerenga kōrero, kei te whakamahi tonu tō roro i ngā pūnga reo me ngā pūnga mahara hei mārama i ngā kupu. Koinei te huarahi e mārama ai koe ki tāu e pānui ana, e maumahara ai ki te tikanga, e hono ai ki ngā wheako o mua.
I te poto, ka whakauruhia e tō roro ngā mōhiotanga mai i ngā rohe rerekē hei hoatu i tētahi pikitia katoa, whai tikanga hoki mō te ao.
He aha ngā āhuatanga ka pā ki tō tirohanga?
Nā te mea e hiahiatia ana te taunga pai o ngā hanganga maha mō te tirohanga, ka taea e ngā āhuatanga hauora maha te whakararuraru i tēnei tukanga. Tērā pea ka pā ētahi āhuatanga ki ngā wāhanga maha o te pūnaha tirohanga i te wā kotahi.
Ko ngā āhuatanga noa ka pā ki te tirohanga ko:
- Ngā mate e pā ana ki te kanohi: Hei tauira, ko te katarata me te glaucoma.
- Ngā mate o te retina me te io whatu: Ngā āhuatanga pēnei i te retinopathy mate huka i puta mai i te mate huka.
- Ngā āhuatanga io: Ka pā kino ngā raruraru o te roro, pērā i te whiu, te pukupuku roro rānei, ki tō tirohanga.
He rerekētanga kei waenganui i te "kite" me te "tirohanga"?
He maha ngā tāngata, tae atu ki ētahi tohunga, e whakamahi tauwhitiwhiti ana i ngā kupu "tirohanga" me te "tirohanga". Heoi, ehara i te mea kotahi tonu. Ka taea e koe te wheako i ngā tukanga tirohanga (pēnei i te whakaaro i tētahi pikitia i roto i tō hinengaro) me te kore e whakamahi i ō kanohi. I tua atu, kei reira ngā mate pūnaha io e mahi pai ai ō kanohi, engari he uaua ki tō roro te whakamārama i tāu e kite nei.
Hei whakamārama:
Ko te tirohanga ko te kaha tinana ki te kite i te mārama me te huri i aua tohu hei tohu mā te roro e tukatuka.
Ko te tirohanga e hiahia ana ki te kaha o te roro ki te whakamārama i aua tohu. Ki te kore taua whakamārama, kāore he tikanga o ngā tohu e tukuna ana e ngā kanohi ki te roro.
Ko tētahi tauira o tēnei rerekētanga ko te agnosia tirohanga . He tino hauora ngā kanohi o te hunga whai mate pēnei, engari he uaua ki te roro te kite i tā rātou e kite nei. Ko tētahi atu tauira motuhake ko te prosopagnosia (te "matapo kanohi" rānei), ka taea e te tangata te kite mārama i te kanohi engari kāore e taea te tautuhi ko wai te tangata nāna.
Me pēhea te tiaki i ō kanohi utu nui
He maha ngā mea ka taea e koe te mahi hei pupuri me te tiaki i tō tirohanga. He mea nui ēnei mahi:
- Te hiranga o ngā whakamātautau kanohi auau: Me whakamātautau kanohi auau te katoa, tae atu ki te hunga e whakapono ana he tirohanga 20/20 ō rātou. Ka taea e ēnei tirotiro te kite i ngā take kāore pea koe e kite. Ko ngā hapa tirohanga pērā i te tirohanga tata (myopia) te tirohanga tawhiti rānei (hyperopia) he maha ngā wā ka puta haere mārire, ā, kāore pea koe e mōhio kua rerekē tō tirohanga kia kitea rā anō e te tohunga.
- Tiakina ō kanohi mai i te whara: Mēnā he tūponotanga ka pā kino ki ō kanohi, me whakarite te tiaki. Mauria he mōhiti tiaki, he pare kanohi, he karu tiaki tika rānei. He mea nui anō hoki ngā mōhiti rā, nā te mea ka tiakina ō kanohi mai i ngā hihi UV kino.
- Whakaarohia tō kai: Me whai huaora me ngā matūkai motuhake ō kanohi kia pai ai te mahi. Mena he pātai āu mō ngā kai hauora mō ngā kanohi, whakapā atu ki tō tākuta tiaki tuatahi, ki tētahi tohunga kanohi rānei.
- Kaua e wareware ki te korikori tinana: E hono ana te hauora o ō kanohi ki tō hauora tinana whānui. Mā te noho korikori tinana ka āwhina i te pupuri i te rere o te toto puta noa i tō tinana, tae atu ki ō kanohi.
- Āraia te momi hikareti me ngā hua tupeka: He kino te momi hikareti, te vape, me te whakamahi tupeka ki tō hauora whānui, ā, ka pā kino ki tō tirohanga. Mā te whakamutu, te karo rānei i ēnei tikanga ka nui te pānga.
- Rapua tonutia te awhina hauora mō ngā panoni ohorere o te tirohanga:Ki te pāngia koe e te ngaronga ohorere o te tirohanga, e te panoni nui rānei o tō tirohanga, me toro atu ki te tākuta tonu. He tohu pea tēnei nō tētahi āhuatanga ohorere hauora nui.
Karere Tangohia ki te Kāinga
Ki te nuinga o tātou, ko te tirohanga te mea tino nui e whakamahia ana e tātou i ia rā. Ahakoa te āhua māmā noa iho, koinei tētahi o ngā mahi tino uaua rawa atu e mahia ana e tō tinana. Hei pupuri i te tirohanga mārama, me mahi tahi ō kanohi, retina, io whatu, me te roro i roto i te tino ōritetanga.
He nui ngā mea ka taea e koe hei tiaki i ō kanohi utu nui. Kia arotahi ki te pupuri i tō hauora kia iti ake ai te wā e manukanuka ana koe mō tō tirohanga, kia nui ake ai te wā e pārekareka ana ki te ao e karapoti ana i a koe. Kaua e wareware ki te tiaki pai i ō kanohi!
