Kia ako tātou i ētahi atu kōrero mō te tirohanga. He aha te Tirohanga 20/20?

Kua rongo koe i tētahi tākuta kanohi, i tētahi tākuta kanohi rānei e kī ana, "Ko tō tirohanga he 20/20" ina haere koe ki te tirotiro kanohi? Kua rongo pea koe i tētahi hoa e kī ana i tēnā. He tokomaha te hunga e whakaaro ana ko te tirohanga 20/20 he tirohanga tino pai, tino tika, ā, he tirohanga tino pai. Engari, he pono rānei tēnā? Kia rapua e tātou te kōrero pakiwaitara "20/20".

He aha te Tirohanga 20/20?

He māmā noa iho, ko te tirohanga 20/20 he tirohanga "noa". Ka ine i te mārama me te koi o te tirohanga i tētahi mea e 20 putu te tawhiti. Ka kiia tēnei e ngā tohunga kanohi he koi o te tirohanga.

Whakaarohia, ina haere koe ki te tirotiro kanohi, ka meinga koe kia titiro ki tētahi tūtohi he reta kei runga. E 20 putu te tawhiti atu i te tūtohi.

• Ko te tau tuatahi (20): Mā tēnei ka mōhio koe ki te tawhiti o tō tawhiti mai i te tūtohi me ngā reta. I ngā whakamātautau kanohi, he 20 tonu tēnei, nā te mea ko te tawhiti paerewa he 20 putu.
• Ko te tau tuarua (20 i tērā taha): Mā tēnei ka mōhio koe e hia putu te tawhiti ka kitea e te tangata he tirohanga noa tētahi mea he rite te mārama me te koi ki tāu e kite ai mai i te 20 putu te tawhiti.

Arā, ki te mea he tirohanga 20/20 tōu, arā, ko tāu e kite ana i te 20 putu te tawhiti, ka taea e te tangata he tirohanga noa te kite mārama mai i te 20 putu te tawhiti. He tirohanga "noa" tēnei, ehara i te tirohanga "tino pai". He mea whakamiharo, tata ki te 35% noa iho o te taupori o te ao he tirohanga 20/20, ahakoa he mōhiti, he karāhe whakapā, he pokanga kanohi rānei tā rātou.

Nā, tirohia, i ētahi wā ka rārangihia tō tirohanga ko te 20/15. Ko te tikanga, ko te mea ka taea e koe te kite mai i te 20 putu te tawhiti, me 15 putu te tawhiti kia mārama ai te tirohanga a te tangata noa. Ko te tikanga he pai ake tō tirohanga i te toharite!

Waihoki, ki te mea ko tō tirohanga he 20/40, ko te tikanga he mea ka kitea e koe mai i te 20 putu te tawhiti ka kitea mārama e te tangata he tirohanga noa mai i te 40 putu te tawhiti. Ko te tikanga he iti iho tō tirohanga i te toharite, nā te mea me tata atu koe ki reira i te tangata noa kia kite mārama ai. Engari kaua e manukanuka, ki te mea he iti iho tō tirohanga i te 20/20, he maha ngā huarahi hei āwhina i a koe ki te whakamārama.

Pērā i te ine a tō tātou whenua i te tawhiti mā te putu, ka whakamahia e ētahi whenua o te ao te pūnaha ine. I aua whenua, ko te tirohanga 20/20 e kiia ana ko te tirohanga 6/6. Arā, ka inehia e rātou mēnā ka taea e koe te kite mārama i tētahi mea e 6 mita te tawhiti, kaua ko te 20 putu.

Ko te tirohanga 20/20 anake te mea nui mō te tirohanga?

Ahakoa he mea nui kia 20/20 te tirohanga kia mārama ai te kite i te ao, tera atu anō ētahi mea e whai tikanga ana mō te tirohanga. Ko ēnei:

• Tirohanga tae: Ko te kaha ki te kite tika i ngā tae.
• Te tūnga o ngā kanohi: He mea tino nui tēnei mō te tirohanga hōhonu me te tirohanga 3D. Me mahi tahi ngā kanohi e rua.
• Te tirohanga pōuri, te tirohanga pō rānei: Te nui o te tirohanga i te pōuri.
• Tirohanga taha: Ko te whānuitanga o te tirohanga ka taea te kite mai i ngā taha me te kore e tahuri te upoko.

Nā, e mārama ana koe? Ko te 20/20 tētahi o ngā āhuatanga o te tirohanga. Ka whai wāhi ēnei āhuatanga katoa ki te tirohanga pai whānui.

He aha te mea nui kia pai te tirohanga?

He mea nui te tirohanga pai mō tō haumaru. Whakaarohia, kia kite i tētahi motuka i te rori, kia kore ai e ngaro tetahi kaupae i te hekenga i te arawhata, me kite pai ēnei katoa.

He mea nui anō hoki te tirohanga pai mō te pupuri i te kounga teitei o te oranga . Ka pā tō tirohanga ki tō mahi, ki ō mahi pāpori, ki ō hiahia, ki te pānui pukapuka, me ēnei mea katoa. Ko te tirohanga pai ko te tikanga me mau mōhiti, me mau karaihe whakapā rānei koe. Ko te mea nui ko te kite mārama kia taea ai e koe te taunekeneke ki te taiao me ngā tāngata e karapoti ana i a koe – ahakoa he whakatikatika, ahakoa kāore rānei.

Ehara i te mea ko te karo noa i ngā kokonga koi te tirohanga pai. Ka āwhina hoki i te pupuri i tō hinengaro kia koi , kia kaha ai koe ki te mahi i ō mahi o ia rā. Ko te pānui i tētahi tohutao i a koe e tunu kai ana, te pānui i ngā tohutohu i runga i te pounamu rongoā, te pānui i ngā whakatūpato i runga i te wai horoi, me te kite i ngā tohu rori me ngā tau huarahi pahi i a koe e taraiwa ana me whai tirohanga pai.

Me pēhea koe e mōhio ai mēnā he tirohanga 20/20 tōu?

Ka whakamātauhia tō tirohanga e te tākuta kanohi mā te whakamātautau kanohi. He maha ngā tikanga ka whakamahia e rātou, ko ngā mea matua ko:

• Whakamātautau tirohanga matatau: Koinei te mea i kōrerotia e au i mua ake nei, me pānui e koe ngā reta i runga i te tūtohi. Ka kiia tēnei tūtohi he tūtohi Snellen . I ētahi wā, hei utu mō ngā reta, ka whakamahia hoki ngā tūtohi me ngā āhua, inā koa mō ngā tamariki nohinohi.
• Retinoscopy: Ko te pupuri i ngā karāhe rerekē ki roto i tō kanohi kia kitea ai ko tēhea te mea e āhei ai koe ki te kite mārama. Ka mahia tēnei e te tākuta i a ia e whiti ana i te rama ki roto i tō kanohi.
• Te Whakamātautau-ā-roto: Kei roto i tēnei ko te titiro ki tētahi mīhini (he whakaahua pea o tētahi whare i roto i tētahi mara, he poihau wera rānei i te pito o tētahi rori roa). Ka ine aunoa te mīhini i tō tirohanga. Ka whakamahia e te tākuta ēnei pānui hei aromatawai anō i tō tirohanga, ā, ka tohua te maha o ngā mōhiti e tika ana māu.

He aha ngā take kāore pea i a au te tirohanga 20/20?

Ko ngā tino take o te tirohanga iti iho i te 20/20 ko ngā hapa tirohanga. Ko ēnei ngā huringa o te āhua o tō kanohi ka pōuri ai te tirohanga. Kei roto i ēnei ko:

• Te Matapōkere, te Tirohanga Mamao rānei: Ko te āhua e pōuriuri ai te āhua o ngā mea e tata ana, ā, i ētahi wā ka pōuriuri haere hoki ngā mea e tawhiti ana.
• Te Matapōkere, te Tirohanga Tata rānei: He āhuatanga e pōuriuri ai ngā mea tawhiti, ā, e kitea mārama ana ngā mea tata.
• Te Matapōkere: He āhuatanga tēnei e puta mai ana i te koroheketanga. Ka uaua te pānui tata ki ngā mea, pērā i ngā pukapuka me ngā nūpepa. I te nuinga o te wā ka tīmata i muri i te 40 tau te pakeke.
• Te Āstigmatism: I tēnei āhuatanga, nā te mea kāore te kanohi i te porowhita tino tika, kāore ngā hihi mārama e arotahi ki te pūwāhi kotahi i roto i te kanohi. Nō reira, ka āhua pōuri, ka pōuri hoki ngā mea tata me ngā mea tawhiti.

Haunga ēnei hapa tirohanga, ka pāngia hoki tō tirohanga e ētahi atu mate kanohi. Ko ētahi tauira ko:

• Katarata: Te kapua o te karāhe o te kanohi.
• Ngā mate o te kornea: Ngā mate e pā ana ki te kornea, te kiriuhi mārama kei mua o te kanohi.
• Te retinopathy e pā ana ki te mate huka: Te kino o te retina i muri o te kanohi i puta mai i te mate huka.
• Glaucoma: Te pakaru o te io whatu nā te pikinga o te pēhanga i roto i te kanohi.
• Ngā mate o te retina: Ngā momo mate ka puta i roto i te retina o te kanohi.
• Ngā āhuatanga pēnei i te strabismus , hei tauira , te amblyopia/kanohi mangere.

Tērā pea he pai ake te tirohanga i te mea noa, engari he iti ake te tūponotanga.

Me pēhea te rongoā mō te iti o te tirohanga?

Mena he hapa tirohanga tōu, he maha ngā maimoatanga e wātea ana hei whakatika i tō tirohanga. Ko te whāinga o ēnei maimoatanga he whakatata atu i tō tirohanga ki te 20/20. Kei roto i ēnei:

• Mōhiti: Koinei te tikanga tino māmā, tino noa hoki.
• Ngā karaihe whakapā: He kōwhiringa pai mō te hunga kāore e pai ki ngā mōhiti.
• Pokanga whakatikatika tirohanga: Ka taea e ngā mahi pēnei i te pokanga laser te whakapai ake i te tirohanga mō ake tonu atu.

Mena he mate kanohi kē atu ōu, me pokanga pea, me rongoā rānei. Hei tāpiri, me mau mōhiti kanohi, me mau karaihe whakapā rānei koe. Ahakoa rā, i ētahi wā, kāore pea koe e kite i te tirohanga pai rawa atu, engari ka taea tonu e koe te kite i te tirohanga e pai ana ki a koe.

Ka taea e au te whakaiti i te mōrearea o te hekenga o taku tirohanga ki raro iho i te 20/20?

Āe, tino tika. He maha ngā mea ka taea e koe te mahi hei pupuri i te hauora o ō kanohi, hei whakaiti hoki i te tūponotanga o te ngoikore o te tirohanga. Ko ētahi o ēnei:

• Mauria he pare kanohi:Mauria ngā mōhiti haumaru ina mahi ana koe me ngā rauemi morearea pea. Mauria hoki ngā mōhiti kanohi ina haere koe ki waho i te rā. Mā tēnei ka tiaki i ō kanohi mai i ngā hihi ultraviolet kino.
• Ki te whakamahi koe i te tupeka, i ngā hua nikotīni rānei, rapua he tohutohu hauora hei whakamutu . He tino kino te momi hikareti ki ngā kanohi.
• Whiwhi kai tika: Me whai huaora me kohuke ō kanohi kia pai ai te mahi. Whakaurua ngā mea pēnei i ngā rau matomato, ngā hua kōwhai, me ngā huawhenua ki roto i tō kai.
• Kia mau ki te taumaha hauora. Ka taea e te momona te arahi ki ngā mate pēnei i te mate huka, ka pā hoki ki ō kanohi.
• Horoia ō ringaringa i ngā wā katoa: Mā tēnei ka ārai i ngā huakita me ngā mate urutā kei uru ki ō kanohi.
• Ki te mau koe i ngā karaihe whakapā, whai i ngā tohutohu mō te pupuri i aua karaihe kia ma, ā, whakakapia i te wā tika.
• Kaua e warewarehia ngā tohu o te kanohi, ngā panonitanga rānei o te tirohanga, ina koa mēnā ka puta ohorere mai ngā panonitanga, ā, me toro atu ki te tākuta tonu.
• Mena kei a koe ngā mate pūmau pēnei i te mate huka, kia mau tonu te whakahaere i aua mate. Ka taea e tēnei te whakawhāiti i ngā pānga kino ki ō kanohi.
• Whakatāhia ō kanohi: Ina koa mēnā he nui āu mahi tirotiro, he nui rānei te wā e titiro ana koe ki te mata rorohiko, he mea nui kia whakatahia ō kanohi. Ka taea e koe te whakamahi i te ture 20-20-20 : I ia 20 meneti, tirohia tetahi mea e 20 putu te tawhiti mō te 20 hēkona.

Hei whakamutunga, ngā mea hei maumahara (Karere hei tango ki te kāinga)

Ahakoa te nui o tō kaute mō te tirohanga, he rite ō kanohi ki ngā matapihi e kite ai koe i te ao e karapoti nei i a koe. He mea nui kia tiakina pai. Mā te mahi pera ka whakaiti i te tūponotanga o te ngaronga o te tirohanga.

Kia maumahara, he tirohanga "noa" noa iho te 20/20, ehara i te tirohanga "tino tika". Mena he āwangawanga āu, he kore rānei e tino mōhio mō tō tirohanga, he mea whakaaro nui kia toro atu koe ki tētahi tohunga kanohi.
