E mōhio ana koe ki te tawhiti tuturu i waenganui i ngā mowhiti pango o ō kanohi e rua (te tawhiti o te karu)? He mea tino nui tēnei mō te hunga e mau ana i ngā mōhiti!

He kaititiro kanohi koe? Kei te rapu rānei koe i tētahi? Mena koinā, i tēnei rā ka kōrero tātou mō tētahi mea tino nui ina whiriwhiri ana i tētahi takirua kaititiro kanohi e tino pai ana ki ō kanohi. He ine tēnei e kiia nei ko te 'Pupillary Distance' . Kāore pea koe i rongo i tēnei kupu i mua. Heoi, he mea tino nui kia mārama tonu tō tirohanga.

He aha te tikanga o tēnei 'tawhiti o te karu'?

Ki te whakarapopoto, ko te tawhiti o te kanohi , ko te PD rānei, ko te tawhiti mai i waenganui o tō kanohi (te porowhita pango i waenganui o tō kanohi) ki waenganui o tō kanohi i tō kanohi kē. I te nuinga o te wā ka inehia tēnei i roto i ngā mirimita (mm). I ētahi wā ka kiia tēnei e ngā tohunga kanohi ko te tawhiti i waenganui i ngā kanohi (ID) .

Ina tukuna he rongoā mō ngā mōhiti ki a koe, he mea tino nui tēnei uara PD. Nā te mea me whakarite tika ngā karāhe o ngā mōhiti ki mua i ō kanohi. Koinei te wā ka mārama rawa atu tō tirohanga. Ki te hoko koe i ngā mōhiti ipurangi, me tino hiahia koe ki tēnei uara PD me te rongoā mai i tō whakamātautau kanohi.

Ka taea e au te ine i tēnei i te kāinga? Me pēhea taku mahi?

Ae, ka taea e koe te whakamātau ki te ine i tō PD i te kāinga mēnā e hiahia ana koe. Heoi, mō te ine tino tika, he pai ake kia inehia e te tohunga tiaki kanohi whai mātauranga . Nā te mea ahakoa he iti noa te panoni o te torutoru mirimita ka pā ki tō tirohanga.

Heoi, ki te hiahia koe ki te whakamātau i a koe anō, ko tāu noa he rūri kua tohua ki ngā mirimita (mm) me te whakaata. He rūri motuhake kei te ipurangi kua hangaia mō te ine i te PD. Kei reira anō hoki ētahi taupānga waea atamai e kī ana ka āwhina i a koe ki te tango i tēnei ine. Heoi, he uaua ki te tino whakapono ki te tika o te ine, ahakoa i ine koe i a koe anō, i te taupānga rānei.

Ki te hiahia koe ki te ine i a koe anō, anei te huarahi:

He uaua pea tēnei, nō reira me manawanui koe.

1. Tuatahi, tū ki mua i te whakaata i roto i tētahi wāhi e mārama ana. Kia 18 inihi te tawhiti o tō mata i te whakaata.

2. Nā, pupurihia te rūri ki tō mata kia kite ai koe i ngā tohu mirimita. Me pupuri te rūri me te mea kei te titiro koe ki tētahi pakitara, i raro noa i ō kanohi.

3. Katia tō kanohi maui.

4. Nā, me titiro noa ki tō kanohi matau, whakatakotoria te tohu kore (0) ki runga i te rūri i waenganui tonu o te porowhita pango o tō kanohi matau. Whakaarohia he rārangi e wehewehe ana i te porowhita pango kia rua, ā, me noho te kore ki runga i taua rārangi. Kaua e nekehia te rūri i tēnei wā, āe? Ki te pēnā koe, me tīmata anō koe.

5. Āe, whakatuwheratia tō kanohi maui, kātahi ka kati tō kanohi matau.

6. Inaianei, tirohia mā tō kanohi maui anake, kimihia te tohu mirimita kei waenganui tonu o te porowhita pango o tō kanohi maui. Pērā i mua, ki te whakaarohia e koe kei roto i te porowhita pango ngā wāhanga e rua, ko te tohu mirimita tata rawa atu ki taua pokapū ko tō uara PD.

Kia maumahara: He uaua te ine i tēnei ara anake, ā, ka taea hoki ngā hapa. Nō reira, rapua he āwhina mēnā ka taea.

He māmā ake anō mēnā ka ine koe me te āwhina a tētahi atu!

He māmā ake anō mēnā ka āwhinahia koe e tetahi. Anei te huarahi ki te mahi:

1. Me noho te tangata e ine ana i tō PD ki mua i a koe, kia 18 inihi te tawhiti i waenganui i ō mata.

2. Me pupuri e ia te rūri ki tō mata, kia kite ai ia i ngā tohu mirimita. Me noho te rūri i raro i ō kanohi (me te mea kei te titiro atu koe ki a ia mai i runga ake i te pakitara).

3. Inaianei, titiro tika atu ki te kanohi maui o te tangata e ine ana i tō PD. Mai i tēnei wā, kaua e nekehia tō mahunga.

4. Me whakanoho e te tangata e ine ana te tohu kore (0) ki runga i te rūri kia tata ki te taha o waho o te mowhiti pango o tō kanohi matau (arā, te taha o te mowhiti pango o tō kanohi matau ka kitea mai i tōna taha maui). Kaua e tukua te rūri kia neke i tēnei wā, ki te kore me tīmata anō koe.

5. Inaianei, titiro tika atu ki te kanohi matau o te tangata e ine ana i tō PD.

6. Me titiro te tangata e ine ana ki te tohu mirimita e tata ana ki te taha o roto o te mowhiti pango o tō kanohi maui (arā, te taha o te mowhiti pango o tō kanohi maui e kitea ana e rātou mai i tō rātou taha matau). Ko taua tohu mirimita te uara PD mōu.

He aha te hiranga o tēnei 'tawhiti o te pūkahukahu' (PD)?

Whakaarohia pēnei: ​​he rite ngā karu o ō kanohi ki ngā karāhe o te kāmera. Ka tomo te mārama mā roto i ēnei. Kātahi ka haere tēnei mārama mā roto i te karāhe o roto i te kanohi ka tau ki te retina kei muri o te kanohi. Koinā te wā ka kite tātou.

Heoi, ki te ngoikore tō tirohanga, kāore tēnei mārama e arotahi tika ana. Koia te take e pōuri ai te tirohanga a ētahi tawhiti. Anei ētahi tauira:

• Tirohanga tawhiti/Hyperopia - ka taea te kite mārama i te tata engari kāore e taea te kite i tawhiti.
• Te Tirohanga Tata/Te Matapouri - Ka taea te kite mārama mai i tawhiti engari kāore e taea te kite tata.
• Te matapōkere - he mate e pā ana ki te tini o te tangata i muri i te 40 tau te pakeke.
• Te Astigmatism - Kāore e tika te arotahi o te mārama nā te panoni o te āhua o te kanohi.

Mō ngā mōhiti, kāore e rite te momo mōhiti mō te katoa. Ko te take o tēnei, he maha ngā āhuatanga e pā ana ki tō tirohanga, pērā i te kaha o tō raruraru tirohanga, me te maha o ngā nekehanga o te astigmatism e pāngia ana e koe.

Mā te ine tika i tō PD me te whakarerekē i te pokapū whatu o ō karāhe kia noho ki waenganui o tō kornea, ka tino whai hua koe i ō karāhe. Mā tēnei ka mārama, ka whakamarie hoki tō tirohanga.

He rite te 'Nasopupillary Distance' ki tēnei?

Āe, tera atu anō tētahi atu inenga nui i tua atu i te PD, arā,Te tawhiti o te ihu . Koinei te tawhiti mai i waenganui o tō kanohi pango ki waenganui o te piriti o tō ihu.

Whakaarohia, tokowhā i roto i te tokorima tāngata kāore i te tino ōrite ngā kanohi me ngā ihu. Arā, kāore te 'Tawhiti Nasopupillary' i te ōrite mō ngā kanohi e rua. I te nuinga o te wā, he iti iho i te 2 mirimita (2mm) tēnei rerekētanga. Heoi, mō te kotahi i roto i te ono tāngata, ka nui ake pea tēnei rerekētanga i te 2 mirimita (2mm). Nā te mea he iti tēnei tawhiti, he tokomaha pea kāore e kite, e mōhio rānei. Heoi, ka pā pea tēnei ki te hoahoa o ngā mōhiti, inā koa ngā karaihe arotahi maha.

Ka aha mēnā he hē te inenga 'Pupillary Distance' (PD)?

Whakaarohia te mea ka tupu mēnā ka mau koe i tētahi takirua mōhiti i hangaia me te ine hē o tō uara PD. Tērā pea ka tīmata koe ki te pāngia e te mamae pēnei:

• Te mamae o ngā kanohi
• Ānini
• Ngā hapa o tō tirohanga - he ahua pōturi, he āhua hē rānei ngā mea

Ahakoa kāore ēnei tohu i te tino mōrearea, ka nui te mamae ka pā ki a koe. Waihoki, ka kino pea tō tirohanga nā te taumahatanga koretake o ō kanohi. Koia te mea nui kia tika te PD.

Ka rerekē tēnei 'tawhiti o te puku' (PD) i ia wā, i ia wā?

I a koe e tamariki ana, ka rerekē tēnei PD i a koe e pakeke haere ana. Arā, ko te PD kei a koe i a koe e tamariki ana kāore i rite ki tō wā e tamariki ana. Heoi, ko te uara o tēnei PD kāore e rerekē i muri i tō pakeketanga.

Heoi, he tino onge ngā wā ka rerekē. Hei tauira, ki te mea me pokanga ō kanohi, tō mata rānei, tera pea ka rerekē paku tō PD i muri i taua pokanga.

He aha te 'tawhiti o te pupura' (PD) toharite?

Ko te uara PD toharite mō te pakeke he tata ki te 63 mirimita `(63mm)`. Heoi, he rerekē tēnei i ia tangata, i ia tangata. Ko te uara PD o te nuinga o ngā pakeke kei waenga i te 50 me te 70 mirimita `(50mm - 70mm)`. Ka rerekē pea ngā uara PD o te hunga tokoiti i waho o tēnei awhe. Ko ētahi tāngata he iti iho i te 45 mirimita `(45mm)` te uara, ko ētahi he teitei ake i te 80 mirimita `(80mm)`.

I roto i ēhea āhuatanga kaua tātou e whakawhirinaki ki tō tātou ake whakaaro?

Mena ka whakamahia noa ō mōhiti mō te kotahi kaupapa (hei tauira, te pānui pukapuka, te mahi māmā rānei), kāore he raru mō tō PD. Heoi anō, tera ētahi wā e tika ana kia ine tika i tō PD. Koinei ngā wā:

• Mena e hiahia ana koe ki ngā karāhe arotahi maha: Ko ēnei he karāhe pēnei i te 'arotahi whakamua', 'arotahi rua' (ngā karāhe ka taea te kite i te tawhiti me te tata), 'arotahi toru' rānei (ngā karāhe ka taea te kite i ngā tawhiti e toru, ngā tawhiti waenga, me te tata). Hei hanga i ia wāhanga o ēnei karāhe kia tino tika, me mōhio koe ki te uara PD.
• Mena me mau tonu koe i ngā mōhiti mō te tirohanga tata me te tirohanga tawhiti:Nā te mea, ina titiro tātou ki tētahi mea kei mua i a tātou, ka paku whāiti haere tō tātou PD mā te 3 mirimita (3mm).
• Mena he hē te tūnga o ngā karu o ō kanohi (pēnei i te strabismus): I ēnei āhuatanga, he mea nui kia inehia tō PD e te tohunga.

I ngā āhuatanga pēnei, he pai ake kia inehia tō PD e te tākuta kanohi, e te tohunga tiaki kanohi rānei, kaua e ine i a koe anō.

He aha te take kāore i whakahuatia ai tēnei mate pāwera (PD) i roto i taku whakahaunga mōhiti?

He raruraru tēnei e pā ana ki te tini tāngata. I ētahi whenua (hei tauira, te Hononga o Amerika) kāore he ture e kī ana me whakaatu te uara PD ina hoatu he rongoā mō ngā mōhiti. Heoi, kei ētahi whenua he ture pēnei. I Sri Lanka, ko te tikanga ka inehia e tō tākuta kanohi, e te kaihanga mōhiti rānei tēnei uara PD, ā, ka puritia ki a rātou.

Tērā pea ka taea e rātou te hoatu he uara PD ki a koe mēnā ka pātai koe. Heoi, tera pea ētahi wāhi e utu ana i tētahi utu motuhake mōna. Heoi, kia whiwhi ai koe i tētahi takirua mōhiti e tau pai ana ki a koe, he mea nui kia ine tika i tēnei uara PD. Nō reira, he mea pai kia pātai atu koe ki tō tākuta kanohi, ki tō toa mōhiti rānei mō tēnei mea.

Nā, anei ngā karere hei kawe ki te kāinga:

Āe, anei ētahi mea hei maumahara māu mai i ngā mea kua kōrerohia e tātou:

• Ko te tawhiti o te karu kanohi (PD) te tawhiti i waenganui i ngā mowhiti pango o ō kanohi.
• He mea tino nui tēnei uara PD mō te hanga mōhiti e mārama ai, e whakamarie ai hoki tō tirohanga .
• Ahakoa ka taea e koe te whakamātau ki te ine i tēnei i te kāinga, he pai ake kia inehia e te tohunga tiaki kanohi kia tino tika ai te ine.
• Ki te hē te inenga o te PD, ka pāngia koe e te mamae pēnei i te ngenge o ngā kanohi, te ānini, te pōrearea o te tirohanga , ā, ka heke pea te tirohanga.
• He mea nui te uara PD tika, inā koa mēnā he karaihe arotahi maha-arotahi tāu e whakamahi ana, he mate rānei pērā i te strabismus.

Nō reira, ā te wā e whakatikahia ai ō mōhiti, kia aro nui ki tēnei uara PD. Nā te mea ahakoa he iti noa te rerekētanga o te kotahi, e rua rānei mirimita, ka pā nui ki tō tirohanga! He mea nui te uara o ngā kanohi hauora e rua i te ao.

Te tawhiti o te karu, ngā mōhiti, te whakamātautau kanohi, te tirohanga, te hauora o te kanohi, te ine i te mate pukupuku, te tawhiti i waenga i ngā karu
