Indlela ezibona ngayo
ukhozi ibona kanjani umhlaba?
Ukubona kwe-UV ngokucaca okuphindwe ka-2–3 kunokwakho
Ukube ubungaboleka amehlo okhozi umzuzwana, umhlaba ubungaqina ube nokugxila okucishe kube ngokwesibonakude. Lundiza phezulu phezu kwensimu, lungabona unogwaja noma ukunyakaza okucijile njengokusika otshanini kusukela ebangeni lapho thina besingabona khona ikhaphethi eluhlaza engaphukiyo kuphela. Umbono walo wombala ucebe kunowethu futhi, wandiswa ngekhoni lesine ku-ultraviolet.
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
Icebile kunokubona komuntu, inobubanzi obengeziwe be-UV/mfusa; amaconsi amafutha alola ukuhlukanisa umbala.
Ama-photoreceptor
I-Tetrachromat (izinhlobo ezi-4 zamaseli e-cone) + amaconsi amafutha anemibala
Iziqongo zokuzwela kwama-cone
- UV/V405 nm
- S (oluhlaza sasibhakabhaka)450 nm
- M (oluhlaza)505 nm
- L (obomvu)565 nm
Ukubona ekukhanyeni okuncane
Isebenza emini; amehlo amakhulu ne-fovea emaphakathi ejulile esebenza njengesikhulisi.
Uma kuqhathaniswa nokubona komuntu
Ukhozi lubona cishe kabili kuya kathathu ngokucija kunawe, cishe ku-20/4 kune-20/20 yakho. Ngaphezu kwemibala emithathu osunayo, lungeza isilinganiso esiphelele se-ultraviolet.
Izici eziphawulekayo
- Ubukhali obuphindwe ka-2-3 kunobomuntu
- Ibona i-ultraviolet (ilandela izilwane ngomchamo obonakalayo ku-UV)
- Ama-fovea amabili eso ngalinye
Imibuzo evame ukubuzwa

Ukube ubungaboleka amehlo okhozi umzuzwana, umhlaba ubungaqina ube nokugxila okucishe kube ngokwesibonakude.

Yimiphi imibala ukhozi engayibona?

Ukubona kuka-ukhozi kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-140 ngedigri (20/4), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). Ibanga layo lokubona lisabalala cishe ngo-340°.
ukhozi ibona kanjani ebumnyameni?
Isebenza emini; amehlo amakhulu ne-fovea emaphakathi ejulile esebenza njengesikhulisi.
Yini eyisipesheli ngokubona kuka-ukhozi?
Ubukhali obuphindwe ka-2-3 kunobomuntu. Ibona i-ultraviolet (ilandela izilwane ngomchamo obonakalayo ku-UV). Ama-fovea amabili eso ngalinye. Iso ngalinye lokhozi liphethe izikhungo ezimbili ezigxilile, noma ama-fovea — elinye libheke phambili, elinye eceleni — futhi lingalandela inyamazane ngokukhanya kwe-ultraviolet kwemikhondo yomchamo amagundane awashiya emigwaqweni yawo.
Ukubona kuka-ukhozi kuqhathaniswa kanjani nokomuntu?
Ukhozi lubona cishe kabili kuya kathathu ngokucija kunawe, cishe ku-20/4 kune-20/20 yakho. Ngaphezu kwemibala emithathu osunayo, lungeza isilinganiso esiphelele se-ultraviolet.
