He aha tāu moemoeā? Me kōrero māmā noa iho!

E kite ana, e mārama ana hoki tātou katoa ki tēnei ao ataahua mā ō tātou kanohi, tika? Whakaarohia, mai i te wā e ara ake ai tātou i te ata tae noa ki te wā e moe ai tātou i te pō, e hia ngā mea e kitea ana e tātou? Ko tēnei āheinga ki te kite me te mārama ki ngā mea e kiia ana ko te tirohanga . Ehara i te mea ngāwari noa iho, he tukanga tino whakamiharo. Nō reira, i tēnei rā, me kōrero tātou mō te tirohanga, me pēhea te tupu, me pēhea te tiaki i ō tātou kanohi.

He aha rawa te tirohanga?

Ki te whakarapopoto, ko te tirohanga te huarahi e mahi tahi ai ō kanohi me tō roro ki te whakamahi i te mārama e whakaatahia ana e ngā mea e karapoti ana i a koe kia taea ai e koe te kite i ngā mea. Ko tētahi tēnei o ō tātou mātai matua e rima. Mā tēnei mātai tirohanga ka mārama, ka mōhio hoki te nuinga o te tangata ki te ao.

Me pēhea te puta o tēnei mea e kīia nei ko te tirohanga? He mea whakamiharo!

Ka tīmata te tirohanga ina kitea e ō kanohi te mārama, ka hurihia hei tohu io, ka tukuna atu ki tō roro mā ō io whatu . Kātahi ka tangohia e te roro ēnei tohu, ka whakamāramahia, ka hurihia hei whakaahua e kitea ana e koe. He ahua uaua, tika? Me wehewehe tātou.

Ō kanohi: He rite ēnei ki ngā kāmera iti e rua?

Kua rongo pea koe i te iwi e whakarite ana i ngā kanohi ki ngā kāmera. Engari ko te ritenga kē. He wāhanga hangarau te kāmera i hangaia i runga i te kanohi tangata.

Whakaarohia he kāmera me te karu arotahi e arotahi ana i te mārama ki tētahi pūoko motuhake i roto i te kāmera. Ka hurihia e taua pūoko te mārama hei tohu hiko. Kātahi ka hurihia e tētahi rorohiko iti i roto i te kāmera aua tohu hei whakaahua. Ka taea e koe te whakahaere i te arotahi o te kāmera. I roto i ētahi kāmera, ka taea hoki e koe te whakahaere i te nui o te mārama e pā ana ki te pūoko.

He karāhe anō hoki ō kanohi. Ka arotahi ēnei karāhe i te mārama, ka tukuna ki te retina, kei muri o te kanohi. He rite te retina ki te pūoko i roto i te kāmera, engari he tino uaua, he matatau ake. Ko te mārama e tau ana ki te retina ka hurihia hei tohu io, ka tukuna ki te roro. Ka tupu tēnei i ētahi wā i te hēkona!

Ko ngā pūkenga motuhake o aua kāmera, arā, te arotahi me te whakahaere i te mārama, ka mahia aunoatia e ō kanohi. Ka taea e te kamo o tō kanohi te whānui me te whakawhāiti, e whakahaere ana i te nui o te mārama e uru ana ki tō kanohi. Hei tāpiri, kei reira ngā uaua e whakahaere ana i te karāhe o tō kanohi. Ko ēnei uaua te mea e āhei ai ngā hihi mārama ki te arotahi kia taea ai e koe te kite mārama i ngā mea i ngā tawhiti rerekē.

Retina: He wāhi whakamiharo hei hopu i te mārama!

He momo pūtau tino motuhake, tino tairongo hoki tō retina . Ka kiia ēnei he pūtau whakaahua-whakaora., arā, "ngā pūtau e kite ana i te mārama." Ina pā te mārama ki ēnei pūtau, ka puta he tauhohenga matū me te hiko i roto i aua pūtau. Koinei te huarahi e kitea ai e aua pūtau te mārama, ka hurihia ai hei tohu io kua whakakōnaetia.

E rua ngā momo matua o ēnei pūtau e aro ana ki te mārama (ngā pūtau whakaahua):

• Ngā tokotoko: Ko ēnei te kawenga matua mō te kite i ngā panonitanga o te kaha o te mārama. Mā ngā tokotoko koe e āwhina ki te kite i ngā mea i te mārama iti, arā, i ngā wāhi pōuri.
• Kone: He tairongo ake ēnei kaiwhakarongo whakaahua, ā, ka taea e rātou te kite i ngā taipitopito pai ake me ngā tae rerekē.

Kia hurihia ēnei tohu io kua whakawaeheretia hei whakaahua, ka tukuna aua tohu e te retina ki ō io whatu.

Ngā io whatu: Ngā taura e kawe ana i ngā karere ki te roro!

He rite ō io whatu ki ngā taura e kawe ana i ngā raraunga. Ka honoa tō retina ki ngā wāhanga rerekē o tō roro. Ka haere aua tohu i roto i ngā io whatu, ka tae atu ki ngā wāhanga rerekē o tō roro, ka wetewetehia, ka tukatukahia hoki.

Roro: Te wāhi i hangaia ai te pikitia!

Ko te taahiraa whakamutunga, ko te taahiraa nui rawa atu hoki, ka puta i roto i tō roro. Ka tangohia e te roro aua tohu kua whakakōrerotia e haere mai ana i roto i ngā io whatu, ka wetewetehia. Kātahi ka whakamahia aua mōhiohio kua wetewetehia hei hanga i tētahi "ahua" mō ia kanohi.

I runga anō i tāu e kite nei, ka mahi tahi ngā wāhanga rerekē o te roro kia tino mārama ai ki taua ahua. Hei tauira, ina pānui koe i tēnei rerenga kōrero, ka whakahohehia hoki ngā wāhanga o te roro e āwhina ana i a koe ki te mārama ki te reo me te maumahara ki ngā maharatanga. Koinei te huarahi e taea ai e koe te mārama ki ēnei kupu, te maumahara ki ō rātou tikanga, me te whakaoho anō hoki i ngā maharatanga e pā ana ki aua kupu. Whakaarohia, ki te kite koe i tētahi hoa i te huarahi, i muri i te hopu a ō kanohi i tana ahua ka tukuna atu ki tō roro, ka mōhio tō roro ki a ia ka mea, "Āe, ko Amal tēnei, tika?" ā, ka taurite ki ngā maharatanga katoa e tika ana (ngā mea i kōrero koe ki a ia, ngā mea i kata tahi ai koe).

He aha ngā āhuatanga hauora ka pā ki ō tātou tirohanga?

He maha ngā wāhanga me ngā hanganga o te tinana e hiahiatia ana kia mahi tahi ai te tirohanga. Nō reira, ka pāngia ia wāhanga e ngā āhuatanga rerekē. Ka pāngia ētahi wāhanga neke atu i te kotahi e ētahi āhuatanga.

Anei ētahi tauira o ngā āhuatanga ka pā ki tō tirohanga:

• Ngā mate e pā ana ki te kanohi: Hei tauira, te katarata, te glaucoma.
• Ngā mate e pā ana ki te retina me te io whatu: Hei tauira, te retinopathy mate huka me te neuritis whatu.
• Ngā mate e pā ana ki te roro: Hei tauira, te ngaronga o te tirohanga nā te whiu, te ngaronga o te tirohanga nā ngā pukupuku roro.

Kaua e wehi i ēnei, he mea nui kia tūpato. Ki te kite koe i ētahi panoni, he pai ake te rapu tohutohu hauora.

He rerekē ngā "Tirohanga" me te "Tirohanga"?

He maha ngā tāngata, tae atu ki ngā tohunga me ngā kaipūtaiao, e whakamahi tauwhitiwhiti ana i ngā kupu "kite" me te "tirohanga". Engari ehara i te mea kotahi. Whakaarohia ka taea e koe te whakamahi i ō pūkenga tirohanga me te kore e kite i tetahi mea (hei tauira, te hanga whakaahua i roto i tō hinengaro). Waihoki, kei reira ngā āhuatanga roro e kore ai e taea e tō roro te tukatuka i ngā mea e kitea ana e ō kanohi.

Hei whakamārama ake i tēnei:

Whakaarohia te tirohanga he pūkenga tinana noa iho . Arā, ka kitea e ō kanohi te mārama, ka hurihia hei tohu hiko me te matū, ka tukuna atu ki tō roro.

Ko te tirohanga e hiahia ana ki te kaha ki te tukatuka i ngā tohu e puta mai ana i ō kanohi. Ki te kore taua tukatuka, kāore he hua o ngā tohu e tukuna ana e ō kanohi ki tō roro.

Ahakoa he āhua rerekē te whakaaro ki ēnei mea e rua, kei reira ētahi mate roro e pā ana ki te tirohanga engari kāore e pā ki te tirohanga. Hei tauira, he mate e kiia nei ko te agnosia tirohanga . Ka taea e te tangata whai agnosia tirohanga te kite, arā, he pai te tirohanga, engari kāore e taea e tōna roro te mārama, te kite rānei i tā rātou e kite nei. Hei tauira, ki te kite rātou i te panana, kāore pea e taea e rātou te mōhio he panana. Ko tētahi atu mate motuhake ko te Prosopagnosia . Ka taea e te hunga whai mate tēnei te kite i ngā kanohi o te tangata, engari kāore e taea e rātou te mōhio ko wai rātou. Kāore pea e taea e rātou te mōhio ki ngā kanohi o ō rātou ake whānau, o ō rātou hoa rānei. He mea whakamiharo?

Me pēhea taku tiaki me te pupuri i taku tirohanga?

He maha ngā mea ka taea e koe te mahi hei tiaki me te pupuri i tō tirohanga utu nui. Anei ētahi o aua mea:

• Tirohia ō kanohi i ia wā: Me tirotiro ngā kanohi o te katoa, tae atu ki te hunga he tirohanga noa (20/20) . Mā te whakamātautau kanohi ka kitea ngā raruraru kāore pea koe e mōhio, e kite rānei. Ko ngā hapa tirohanga , pērā i te tirohanga tata (Myopia) te tirohanga tawhiti rānei (Hyperopia), ka ngaro pea te tirohanga i roto i te wā. Nō reira, kāore pea koe e kite i te tīmatanga. Mā te whakamātautau kanohi ka kitea ēnei raruraru i mua i tō mōhio.

• Tiakina ō kanohi: He mea nui kia mau i ngā ārai kanohi i ngā wā e tūpono ana te kino o ngā kanohi. Ka taea e ngā mōhiti tiaki, ngā karu ārai , ngā kopare kanohi, ngā parepare rānei te āwhina i tēnei. Hei tauira, ki te mea kei te whakarewa koe, kei te tapahi rakau, kei te horoi puehu rānei i te kāinga, he mea tino nui ēnei. He huarahi pai hoki ngā karu ārai hei tiaki i ō kanohi. Ka tiakina ō kanohi mai i ngā hihi UV kino.Ārai i. Nā te mea he kaha te rā i Sri Lanka, he tino pai te whakamahi i ngā mōhiti kanohi.

• Kia tiakina tō kai: Me whai huaora me ngā matūkai ō kanohi kia pai ai te mahi. Mena he pātai āu mō tēnei, ka taea e koe te kōrero ki tō tākuta whānau, ki tētahi tākuta kanohi rānei. He mea tino nui te kai i tētahi kai taurite.

• Whakatairangahia te korikori tinana: Ko te hauora o ō kanohi he whakaata i tō hauora whānui. Mā te korikori tinana auau me te noho pukumahi ka āwhina i te pupuri i te hauora o ō kanohi (me tō tinana katoa).

• Āraia te kai tupeka: Ka pā kino te momi hikareti, te vape, me te whakamahi i te tupeka kore auahi ki tō hauora me tō tirohanga. Mā te whakamutu i ēnei mea, te kore rānei e tīmata, ka nui te rerekētanga.

• Ki te pāngia koe e ngā panoni ohorere o tō tirohanga, e te ngaronga rānei o te tirohanga, rapua tonutia he awhina hauora, kaua e whakaroa: He tohu whakatūpato ēnei mō tētahi raruraru nui ake. Ko te ngaronga ohorere o te tirohanga he take ki te rapu awhina hauora. Mena he mate hauora tōu ka puta ai ngā panoni ohorere o te tirohanga, mā tō tākuta, mā tō tākuta kanohi rānei koe e kī atu āhea koe me rapu maimoatanga motuhake.

Ko te mea nui ko te tiaki i ō kanohi. Ki te kite koe i tētahi panoni iti, kaua e warewaretia.

Whakarāpopototanga: Ngā mea hei maumahara

Ki te tini o te tangata, ko te tirohanga te mea nui rawa atu e whakamahia ana e rātou i ia rā. Ahakoa he āhua māmā noa iho, ko tētahi o ngā tukanga tino uaua o roto i ō tātou tinana. Kia pai ai te mahi a tō tirohanga, me mahi tahi ngā wāhanga katoa o tō kanohi, tae atu ki te retina, ngā io whatu, me te roro.

Waimarie, he maha ngā mea ka taea e koe te mahi hei tiaki me te pupuri i ēnei kanohi utu nui. Kātahi, kaua e manukanuka ki ngā mea ka kitea e koe, engari ka taea e koe te pai ki te titiro ki ngā mea e hiahia ana koe kia kite. Nō reira, tīmata ki te tiaki i ō kanohi i tēnei rā!
