Sonke siyawubona futhi siwuqonda lo mhlaba omuhle ngamehlo ethu, akunjalo? Cabanga nje, kusukela ngesikhathi sivuka ekuseni kuze kube yilapho silala ebusuku, zingaki izinto esizibonayo? Leli khono lokubona nokuqonda izinto libizwa ngokuthi umbono . Akuyona nje into elula, kuyinqubo emangalisayo kakhulu. Ngakho-ke namuhla, ake sixoxe ngokuthi umbono uyini, kwenzeka kanjani, nokuthi singawanakekela kanjani amehlo ethu.

Uyini ngempela umbono?

Kalula nje, ukubona kuyindlela amehlo akho nobuchopho obusebenzisana ngayo ukusebenzisa ukukhanya okuboniswa ezintweni ezikuzungezile ukuze kukuvumele ubone izinto. Kungenye yezinzwa zethu ezinhlanu eziyinhloko. Iningi labantu liyaqonda futhi liyaqaphela umhlaba ngalo mqondo wokubona.

Kwenzeka kanjani lokhu okubizwa ngokuthi umbono? Kuyamangalisa!

Ukubona kuqala lapho amehlo akho ebona ukukhanya, ekuguqula kube izimpawu zemizwa, bese ezithumela ebuchosheni bakho ngezinzwa zakho zokubona . Ubuchopho bube sebuthatha lezi zimpawu, buzichaze, bese buziguqula zibe izithombe ozibonayo. Kuzwakala kuyinkimbinkimbi, akunjalo? Ake sikuchaze kancane.

Amehlo akho: Ingabe afana namakhamera amabili amancane?

Cishe uke wezwa abantu bevame ukuqhathanisa amehlo namakhamera. Kodwa empeleni kuphambene nalokho. Ikhamera iwuhlobo lobuchwepheshe oluklanywe ngokweso lomuntu.

Cabanga ngekhamera enelensi egxilisa ukukhanya ku-sensor ekhethekile ngaphakathi kwekhamera. Leyo sensor iguqula ukukhanya kube yizimpawu zikagesi. Ikhompyutha encane ngaphakathi kwekhamera bese iguqula lezo zimpawu zibe isithombe. Ungalawula ukugxila kwekhamera. Kwamanye amakhamera, ungalawula nokuthi kungakanani ukukhanya okushaya i-sensor.

Amehlo akho nawo anamalensi. Lawa malensi agxila ukukhanya futhi akuqondise ku -retina, etholakala ngemuva kweso. I-retina ifana nenzwa ekhamera, kodwa iyinkimbinkimbi kakhulu futhi ithuthukile. Ukukhanya okuwela ku-retina kuguqulwa kube izimpawu zemizwa bese kuthunyelwa ebuchosheni. Lokhu kwenzeka izikhathi eziningana ngomzuzwana!

Amakhono akhethekile alawo makhamera, okungukuthi ukugxila nokulawula ukukhanya, enziwa ngokuzenzakalelayo ngamehlo akho. Impumputhe esweni lakho ingavuleka futhi inciphe, okulawula inani lokukhanya okungena esweni lakho. Ngaphezu kwalokho, kunemisipha elawula ilensi yeso lakho. Le misipha yiyo evumela imisebe yokukhanya ukuthi igxile ukuze ukwazi ukubona izinto ezikude ezahlukene ngokucacile.

I-Retina: Indawo emangalisayo yokubamba ukukhanya!

I-retina yakho uhlobo lweseli olukhethekile kakhulu noluzwela kakhulu. Lawa abizwa ngokuthi ama-photoreceptor., okungukuthi, "amangqamuzana azwa ukukhanya." Uma ukukhanya kwehlela kulawa maseli, kwenzeka ukusabela kwamakhemikhali kanye nogesi ngaphakathi kwalawo maseli. Yileyo ndlela lawo maseli athola ngayo ukukhanya futhi akuguqule kube izimpawu zemizwa ezifihliwe.

Kunezinhlobo ezimbili eziyinhloko zala maseli azwela ukukhanya (ama-photoreceptor):

• Izinduku: Lezi zinomthwalo wemfanelo omkhulu wokubona izinguquko ekukhanyeni. Izinduku yizo ezikusiza ukuthi ubone izinto ekukhanyeni okuphansi, okungukuthi ezindaweni ezimnyama.
• Amakhoni: Lawa ma-photoreceptors azwela kakhulu futhi angakwazi ukubona imininingwane emincane nemibala ehlukene.

Uma lezi zimpawu zemizwa ezibhalwe phansi seziguqulwe zaba izithombe, i-retina ithumela lezo zimpawu emithanjeni yakho yokubona.

Izinzwa zamehlo: Izintambo ezithwala imiyalezo ebuchosheni!

Izinzwa zakho zokubuka zifana nezintambo ezithwala idatha. Zixhuma i-retina yakho nezingxenye ezahlukene zobuchopho bakho. Lezo zimpawu zihamba ngemithambo yokubuka futhi zifinyelele ezingxenyeni ezahlukene zobuchopho bakho, lapho zihlukaniswa khona futhi zicutshungulwe khona.

Ubuchopho: Lapho isithombe senziwe khona!

Isinyathelo sokugcina nesibaluleke kakhulu senzeka ebuchosheni bakho. Ubuchopho buthatha lezo zimpawu ezifihliwe eziza ngemizwa ye-optic bese buzihlaziya. Bube sebusebenzisa lolo lwazi olufihliwe ukudala "isithombe" seso ngalinye.

Kuye ngokuthi ubonani, izingxenye ezahlukene zobuchopho ziyasebenzisana ukuze ziqonde ngokugcwele leso sithombe. Isibonelo, uma ufunda lo musho, izingxenye zobuchopho ezikusiza ukuthi uqonde ulimi futhi ukhumbule izinkumbulo nazo ziyasebenza. Yileyo ndlela ongaqonda ngayo la magama, ukhumbule incazelo yawo, futhi uvuselele izinkumbulo ezihlobene nawo. Cabanga nje, uma ubona umngane emgwaqweni, ngemva kokuba amehlo akho ethwebula isithombe sakhe bese esithumela ebuchosheni bakho, ubuchopho bakho buyasiqaphela bese buthi, "O, lo ngu-Amal, akunjalo?" futhi buhambisana nazo zonke izinkumbulo ezifanele (lezo owakhuluma naye, lezo owahleka nazo).

Yiziphi izimo zezokwelapha ezingathinta amehlo ethu?

Ukubona kudinga izingxenye eziningi ezahlukene kanye nezakhiwo zomzimba ukuze kusebenze ndawonye. Ngakho-ke, izimo ezahlukene zingathinta ingxenye ngayinye yalezi. Ezinye izimo zingathinta izingxenye ezingaphezu kweyodwa.

Nazi ezinye zezibonelo zezimo ezingathinta ukubona kwakho:

• Izifo ezihlobene namehlo: Isibonelo, i-cataracts, i-glaucoma.
• Izifo ezihlobene ne-retina kanye ne-optic nerve: Isibonelo, i-diabetesic retinopathy kanye ne-optic neuritis.
• Izifo ezihlobene nobuchopho: Isibonelo, ukulahlekelwa umbono ngenxa yesifo sohlangothi, ukulahlekelwa umbono ngenxa yezimila zobuchopho.

Ungesabi lokhu, kubalulekile ukuqaphela. Uma ubona noma yiziphi izinguquko, kungcono ukufuna iseluleko sezokwelapha.

Ingabe "Umbono" kanye "Nokubona" ​​kuyizinto ezimbili ezihlukene?

Abantu abaningi, ngisho nochwepheshe nososayensi, basebenzisa amagama athi "umbono" kanye "nokubona" ​​ngokushintshana. Kodwa awafani. Cabanga ukuthi ungasebenzisa amakhono akho okubona ngaphandle kokubona okuthile (isibonelo, ukudala izithombe engqondweni yakho).

Ukubona kudinga ikhono lokucubungula izimpawu ezivela emehlweni akho. Ngaphandle kwalokho kucubungula, izimpawu amehlo akho azithumela ebuchosheni bakho azisizi ngalutho.

Nakuba kungase kubonakale kungavamile ukucabanga ngalezi zinto ezimbili ngokwehlukana, kunezimo zobuchopho ezithinta umbono ngaphandle kokuthinta ukubona. Isibonelo yisimo esibizwa ngokuthi i-visual agnosia . Umuntu one-visual agnosia angabona, okusho ukuthi ukubona kwakhe kulungile, kodwa ubuchopho bakhe abukwazi ukuqonda noma ukuqaphela lokho akubonayo. Isibonelo, uma ebona ubhanana, angase angakwazi ukukubona njengobhanana. Esinye isimo esithile yi -Prosopagnosia . Abantu abanalesi simo bangabona ubuso babantu, kodwa abakwazi ukuqaphela ukuthi bangobani. Bangase bangakwazi ukuqaphela ubuso bomndeni wabo noma babangane babo. Akumangalisi yini?
