Indlela ezibona ngayo
ingwenya ibona kanjani umhlaba?
Umudwa obukhali odabula emngceleni wamanzi
Ingwenya ecwathile emgceleni wamanzi ihlonyiswe amehlo afanele ngempela umsebenzi. Umdwebo ovundlile wombono ocijile udabula i-retina yayo, uyinika ibhande elicacile, elibanzi ngqo endaweni yamanzi lapho inyamazane iza khona ukuzophuza. Inhlamvu yeso emise okoluvo kanye nongqimba olukhanyayo bese kuguqula lawo mehlo abe ngamathuluzi anamandla okuzingela ebusuku.
Umuntu ≈ 60 cpd (20/20)
Ukuqhathanisa imibala
How each colour shifts when seen through this animal's eyes, using the same colour model as the app. Tones a screen can't emit (such as ultraviolet) are shown as an approximation.
Ukubona umbala
I-dichromacy eluhlaza sasibhakabhaka-phuzi; ecacile kuwo wonke umkhathizwe, ifiphele ngenhla nangaphansi.
Ama-photoreceptor
I-Dichromat enomugqa ovundlile onobukhali obukhulu + i-tapetum lucidum
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)443 nm
- L (oluhlaza)535 nm
- L (red)566 nm
Ukubona ekukhanyeni okuncane
Kuhle kakhulu; isikhala esiqondile esiyisikwele nene-tapetum lucidum ukuze izingele ebusuku.
Uma kuqhathaniswa nokubona komuntu
Ingwenya ibona cishe ku-20/70 kune-20/20 yakho nemibala emibili kunemithathu. Ekuskeneni umkhathizwe umdwebo wayo ovundlile wombono ocijile udlula iso lakho, futhi umbono wayo wasebusuku uwudlula kakhulu owakho.
Izici eziphawulekayo
- Umugqa ovundlile onobukhali obukhulu
- Isikhala esiqondile esiyisikwele
- Ukukhanya kwe-tapetum emehlweni
Imibuzo evame ukubuzwa
ingwenya ibona kanjani umhlaba?
Ingwenya ecwathile emgceleni wamanzi ihlonyiswe amehlo afanele ngempela umsebenzi.

Yimiphi imibala ingwenya engayibona?

Ukubona kuka-ingwenya kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-8.8 ngedigri (20/70), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-270°.
ingwenya ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-8.8 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-7 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
ingwenya ibona kanjani ebumnyameni?
Kuhle kakhulu; isikhala esiqondile esiyisikwele nene-tapetum lucidum ukuze izingele ebusuku.
Yini eyisipesheli ngokubona kuka-ingwenya?
Umugqa ovundlile onobukhali obukhulu. Isikhala esiqondile esiyisikwele. Ukukhanya kwe-tapetum emehlweni. Amehlo engwenya akhanya abomvu ekukhanyeni kwesibani, ngenxa ye-tapetum efana nesibuko esemuva kwe-retina. Ibhande layo elivundlile lombono ocijile lisho ukuthi cishe alidingi ukunyakazisa ikhanda layo ukuze liskene ugu lonke ukuze libone ukunyakaza.
Ukubona kuka-ingwenya kuqhathaniswa kanjani nokomuntu?
Ingwenya ibona cishe ku-20/70 kune-20/20 yakho nemibala emibili kunemithathu. Ekuskeneni umkhathizwe umdwebo wayo ovundlile wombono ocijile udlula iso lakho, futhi umbono wayo wasebusuku uwudlula kakhulu owakho.
