Kua titiro kē koe ki ō kanohi i roto i te whakaata, ā, kua whakaaro koe ki te uaua o ngā mea kei roto? Ko te wāhanga mā o te kanohi me te āri pango anake tā tātou e kite nei. Engari he rite ō tātou kanohi ki tētahi kāmera iti e mahi pai ana. I tēnei rā ka kōrero tātou mō tētahi wāhanga huna i roto i te kanohi he mea nui ki te tirohanga. Ko taua wāhanga ko te uvea.
He aha tēnei Uvea?
I te whakarapopototanga, ko te uvea te paparanga waenga o ngā paparanga matua e toru e hanga ana i tō tātou kanohi. He rite ki te paparanga waenga o te hanawiti. Ko te ingoa Uvea i ahu mai i ngā kupu Latina me Kariki mō te "karepe." I tapaina ai nā te mea he rite tōna āhua ki te karepe ina tirohia mai i waho.
Ko tētahi atu ingoa mō tēnei ko te "tunic vascular." Ko te tikanga o te "tunic" he kākahu rite ki te hāte. Ko te tikanga o te "vascular" he uaua toto, he mea rānei e pā ana ki te rere o te toto. Nō reira, ka takaihia hoki tēnei uvea ki tō tātou kanohi pērā i te hāte, ā, kua whakakiia ki ngā uaua toto e tuku ana i te toto e hiahiatia ana e te kanohi.
He aha ngā wāhanga matua o te uvea me ā rātou mahi?
E toru ngā wāhanga matua o te uvea. He mahi motuhake tā ia wāhanga. Me titiro tātou ki tēnei ara kia māmā ake ai te mārama.
| Wāhanga | Ko tana mahi he mea ngāwari noa iho |
|---|---|
| Ārihi | Koinei te wāhanga e whakatau ana i te tae o ō kanohi. Ko tēnei wāhanga te kawenga mō ngā tae kanohi pēnei i te kikorangi, te parauri, me te mangu. Ā, pērā i te karu o te kāmera, ka whānui, ka whakawhāiti hoki hei whakahaere i te nui o te mārama e tomo ana ki te kanohi. Ka mimiti i te rā, ka whānui hoki i te pōuri hei āwhina i te kanohi kia whiwhi i te mārama e hiahiatia ana. |
| Tinana kiriuhi | Kei muri i te iris tēnei. Ka āwhina tēnei wāhanga o te kanohi ki te whakarerekē i te āhua o te karu o te kanohi, me te 'arotahi' kia mārama ai te kite ina pānui pukapuka ana, ina titiro rānei ki tētahi mea i tawhiti. Ehara i te mea koinā anake, ka āwhina anō hoki ki te whakaputa wai i roto i te kanohi (waikawa wai), e āwhina ana ki te pupuri i te āhua o te karu. |
| Koroiti | Koinei te wāhanga nui rawa atu o te Uvea. He kiriuhi angiangi tēnei e kī ana i ngā uaua toto. Whakaarohia tō kanohi he whare. Kātahi ka rite tēnei Choroid ki te pūnaha paipa e tuku wai ana ki taua whare. Koinei te mea e whakarato ana i te toto me te kai e hiahiatia ana e te kanohi, inā koa te retina, e homai ana ki a tātou te tirohanga. Ka whakaitihia hoki e te tae melanin i roto i tēnei te whakaata koretake o te māramatanga ki roto i te kanohi. |

Me pēhea taku pupuri i te hauora o ōku kanohi?
He iti noa ngā mea māmā ka taea e koe te mahi hei pupuri i te hauora o ō kanohi, tae atu ki te uvea.
- Tirohia ō kanohi i ia wā: Ahakoa he mōhiti āu, he mea nui kia toro atu koe ki tētahi tākuta kanohi i te iti rawa i te kotahi, i te rua rānei i te tau, kia kitea ai ngā raruraru i mua i te huri hei tohu.
- Tiakina ō kanohi: Ki te mea kei te whakarewa koe, kei te mahi rakau, kei te mahi rānei ki te puehu, ki ngā matū rānei, kia mau koe i ngā mōhiti haumaru . Kāore e ranea ō mōhiti mō tēnā.
- Kaua e hikareti: Kāore te hikareti me te vape i te pai mō ngā uaua toto ngawari o roto i te kanohi. He tino kino ki te hauora o ngā kanohi.
- Kaua e warewarehia ngā mate urutā: Ki te whero tō kanohi, ki te pupuhi, ki te mākūkū rānei mō ētahi rā, kaua e warewarehia. Tērā pea he mea nui, nō reira me toro atu ki te tākuta tonu.
Āhea ahau me toro atu ki tētahi tākuta kanohi?
Haunga ngā whakamātautau kanohi auau, ki te pāngia koe e tētahi o ēnei tohu, me toro atu tonu ki tētahi tākuta kanohi.
- Mena ka roa ake ngā tohumate kanohi i ngā rā torutoru .
- Mena kei te whakararuraru aua tohu i ō mahi o ia rā .
- Mena ka pāngia koe e tētahi momo ngaronga tirohanga .

Engari ki te mea he raruraru kei roto, ka tino whakamataku.
