Izinyoka zibona imithombo yokushisa ngamehlo azo. Izinyoni ezidla inyama zingabona amagundane ebangeni elingamamitha angama-500. Izimpukane zibona ngokushesha kunathi. Isithombe sikamabonakude sibonakala kubo sihamba kancane, njengoba bekwazi ukucubungula izithombe eziningi kakhulu ngomzuzwana kunathi thina bantu. Umbono wazo zonke izilwane uvumelana nemvelo nokuziphatha, kuhlanganise nezilwane ezifuywayo. Ngezinye izindlela bangaphezu kwethu, kwezinye, singenza kangcono.
Izinja ziyakwazi ukubona eduze futhi azikwazi ukubona okuluhlaza
Ozakwethu abanemilenze emine banezinduku eziningi emehlweni abo ukwedlula thina bantu. Lokhu kubenza babone kahle ngisho nasekukhanyeni okuncane. Uma kukhona isigayegaye, nabo bazizwa ebumnyameni. Ngokungafani nabantu abanempilo enhle, izinja ziyakwazi ukubona eduze. Inja ayiboni lutho olunganyakazi futhi iqhele ngamamitha ayisithupha ukusuka kuwe. Ngakolunye uhlangothi, abantu bayakwazi ukubona ngokucacile ngisho nalapho beqhele ngamamitha angu-20.
Ukubona umbala akukaze kuhlotshaniswe nezinja; Kodwa-ke, njengoba kuvame ukucatshangwa, aziboni umbala. Izinja zingakwazi ukubona imibala ethile, kodwa hhayi ama-nuances amaningi njengabantu. Singakwazi ukubona ubude begagasi kuhlu olubomvu, oluluhlaza, noluhlaza okwesibhakabhaka kanjalo nemibala engaba ngu-200. Izinja zinezinhlobo ezimbili kuphela zamakhoni ngakho-ke ngokuvamile zibona okuluhlaza okwesibhakabhaka, okunsomi, okuphuzi, nokunsundu. Amathoni abomvu abonakala ephuzi enja, ayiboni nhlobo eluhlaza.
Amakati Ane-Residual Light Amplifier
Amehlo amakati ethu afuywayo ajwayele ngokukhethekile ukubona ebumnyameni. Abafundi bayo banganwebeka kakhulu, okusho ukuthi ukukhanya okwanele kusengafinyelela ku-retina. Ngemuva kwe-retina kukhona ungqimba olukhanyayo, i-tapetum, uhlobo lwesikhulisi sokukhanya esiyinsalela esidlulisela ukukhanya ku-retina futhi. Lokhu kusho ukuthi ukukhanya okuvela enyangeni kwanele ukuze bakwazi ukuzingela ngempumelelo. Izinti ezengeziwe futhi zivumela ukuthi zibone kangcono ukunyakaza okusheshayo. Singabona ukunyakaza okuhamba kancane kangcono kunekati. Ukubona kwethu imibala nakho kuhlukahluka kakhulu; kuyingwe yasekhaya, umhlaba ubonakala uluhlaza okwesibhakabhaka futhi uphuzi.
Amahhashi Awayithandi Imibala Emnyama
Amehlo amahhashi atholakala ezinhlangothini zekhanda. Ngenxa yalokho, inkambu yokubuka ihlanganisa i-radius enkulu kakhulu - inokubuka cishe yonke indawo. Babona nezitha eziza ngemuva kusenesikhathi. Kuyasiza futhi ukuthi babone kude futhi babone kangcono uma bekude kunokuba baqonde phambili. Uma ufuna ukubona into ngokucacile, udinga ukuguqula ikhanda lakho ukuze ukwazi ukubuka into ngawo womabili amehlo ngesikhathi esisodwa. Isilwane sidinga isikhathi esithile sokwenza lokhu, kodwa lokhu akuyona into embi. Ukuqaphela ukunyakaza bekulokhu kubaluleke kakhulu esilwaneni esibalekayo kunokugxila ezintweni ezimile.
Ukubona umbala emahhashini akukakahlolisiswa ngokugcwele. Kukholakala ukuthi angakwazi ukuhlukanisa ikakhulukazi phakathi kophuzi noluhlaza okwesibhakabhaka. Ababoni nokubomvu nokuwolintshi. Imibala emnyama ibonakala iyingozi kakhulu kunemibala ekhanyayo; imibala elula kakhulu iphuphuthekisile. Njengamakati, amahhashi anongqimba olukhethekile emehlweni awo oluthuthukisa kakhulu ukubona ebumnyameni. Abazithandi izinguquko ezibukhali ukusuka ekukhanyeni kuye komnyama. Bese beba yizimpumputhe isikhashana.
Onogwaja Ababona Phambili kanye Nonogwaja Ababomvu-Oluhlaza-Abayimpumputhe
Kunogwaja, njengesilwane esizingelayo, ukubuka okuhle kwendawo yonke kubaluleke kakhulu kunokubona okubukhali. Iso ngalinye lingamboza indawo ecishe ibe ngu-170 degrees. Nokho, banendawo eyimpumputhe eyi-10 degree phambi kobuso babo; kodwa angabona indawo ngokuhogela nangokuthinta.
Lapho kuhwalala nakude, abanendlebe babona kahle kakhulu futhi ngenxa yalokho basheshe babone izitha zabo. Nokho, zibona izinto eziseduze kwazo zilufifi. Ngakho-ke, onogwaja bavame ukubona abantu ngokuhogela noma ngezwi kunangokubukeka kwabo. Izindlebe ezinamadlebe amade nazo azinawo ama-receptor, okwenza zingakwazi ukubona umbala. Abanayo i-cone receptor ye-shades of red, futhi abakwazi ukuhlukanisa lo mbala koluhlaza.
