Indlela ezibona ngayo
ushaka ibona kanjani umhlaba?
Ayiboni umbala, umzingeli othanda umehluko wombala
Naphezu kwesabiso sabo, oshaka abaningi abafundiwe babonakala beyizimpumputhe zombala ngokuphelele, befunda ulwandle ngokukhanya nokungqubuzana kuphela. Uhlobo olulodwa lwekhoni olulungiselelwe okuluhlaza okwesibhakabhaka-luhlaza — umbala ohamba kakhulu emanzini olwandle — lwenza umsebenzi wasemini, lusekelwa isibuko esikhulisa ukukhanya sokujula. Kushaka, umuntu obhukudayo uyisithunzi esinyakazayo kunombala.
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
Ukubona umbala okuncane noma okungekho; iqondiswa ukukhanya, ukuqhathanisa nokunyakaza. Oluhlaza sasibhakabhaka-luhlaza yilapho ulwandle ludlulisa khona ukukhanya kangcono.
Ama-photoreceptor
I-Monochromat yamaseli e-cone (uhlobo olulodwa lweseli e-cone) + amaseli e-rod
Iziqongo zokuzwela kwama-cone
- I-cone eyodwa532 nm
Ukubona ekukhanyeni okuncane
I-tapetum lucidum enamandla yamanzi ajulile nokukhanya okuncane.
Uma kuqhathaniswa nokubona komuntu
Imininingwane kashaka ecishe ibe ngu-20/200 ihamba emuva kwe-20/20 yakho, futhi lapho wena ubona izigidi zemibala yena akaboni namunye. Ungqimba oluqinile olubuyisa ukukhanya ngemuva kwe-retina yakhe lumvumela ukuthi azingele emanzini aluvivi, ajulile lapho wena ubungaba yimpumputhe khona.
Izici eziphawulekayo
- Cishe ayiboni umbala
- Ukubona okuhle kakhulu ukuqhathanisa nokunyakaza
- I-electroreception ne-mechanoreception zihlanganisa ukubona
Imibuzo evame ukubuzwa
ushaka ibona kanjani umhlaba?
Naphezu kwesabiso sabo, oshaka abaningi abafundiwe babonakala beyizimpumputhe zombala ngokuphelele, befunda ulwandle ngokukhanya nokungqubuzana kuphela. Uhlobo olulodwa lwekhoni olulungiselelwe okuluhlaza okwesibhakabhaka-luhlaza — umbala ohamba kakhulu emanzini olwandle — lwenza umsebenzi wasemini, lusekelwa isibuko esikhulisa ukukhanya sokujula. Kushaka, umuntu obhukudayo uyisithunzi esinyakazayo kunombala. Ukubona umbala okuncane noma okungekho; iqondiswa ukukhanya, ukuqhathanisa nokunyakaza. Oluhlaza sasibhakabhaka-luhlaza yilapho ulwandle ludlulisa khona ukukhanya kangcono.
Yimiphi imibala ushaka engayibona?

Ukubona kuka-ushaka kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-4 ngedigri (20/200), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-340°.
ushaka ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-4 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-15 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
ushaka ibona kanjani ebumnyameni?
I-tapetum lucidum enamandla yamanzi ajulile nokukhanya okuncane.
Yini eyisipesheli ngokubona kuka-ushaka?
Cishe ayiboni umbala. Ukubona okuhle kakhulu ukuqhathanisa nokunyakaza. I-electroreception ne-mechanoreception zihlanganisa ukubona. Ngenxa yokuthi oshaka mhlawumbe babona kuphela ngezinga lokukhanya, imibhalo enokungqubuzana okuphezulu kwezinye izinyoka zolwandle ingase ibaluleke kubo kunanoma yimuphi umbala. Abacwaningi basebenzise lowo mqondo lapho beklama izicwatho zamanzi ezivimba oshaka.
Ukubona kuka-ushaka kuqhathaniswa kanjani nokomuntu?
Imininingwane kashaka ecishe ibe ngu-20/200 ihamba emuva kwe-20/20 yakho, futhi lapho wena ubona izigidi zemibala yena akaboni namunye. Ungqimba oluqinile olubuyisa ukukhanya ngemuva kwe-retina yakhe lumvumela ukuthi azingele emanzini aluvivi, ajulile lapho wena ubungaba yimpumputhe khona.
