Indlela ezibona ngayo
ihhashi ibona kanjani umhlaba?
Cishe 360°, nezindawo ezimbili ezingabonwa
Amehlo amabili amakhulu akhwele ezinhlangothini zekhanda elide lehhashi, elinika umbono ocishe uyisiyingi ngokuphelele womhlaba. Lokhu kulungele isilwane esidla utshani okumele siqaphe izilwane eziyingozi ikhala laso lisotshanini. Libona okuluhlaza okwesibhakabhaka nokusaphuzi ngokusobala, yize okubomvu kuhlangana notshani, futhi lokhu kwakheka kushiya izindawo ezimbili ezimangalisayo eziyimpumputhe: enye ngaphambi kwekhala lalo, enye ngemuva komsila walo.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ihhashi kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-23 ngedigri (20/26), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-350°.
ihhashi ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-23 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-3 ukuze ibone imininingwane oyibonayo. Isimo sakho nokunyakaza kwakho kufika kucacile; ukubukeka kobuso bakho akufiki.
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.
Yimiphi imibala ihhashi engayibona?
Ibona kahle okuluhlaza sasibhakabhaka nokuluhlaza, kodwa idida obomvu noluhlaza. Okuphuzi kubukeka kucwebezela kakhulu kuyo.
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone)
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)428 nm
- M (oluhlaza-phuzi)539 nm
ihhashi ibona kanjani ebumnyameni?
I-tapetum lucidum; ukubona okuhle ekukhanyeni okuncane nokunyakaza.
Ukubona kuka-ihhashi kuqhathaniswa kanjani nokomuntu?
Ku-20/26, ihhashi linobuqondi obucije kunazo zonke izilwana ezincelisayo lapha, yize lisagoduka le kwe-20/20 yakho. Wena uthola imibala emithathu eyinhloko kubanga elingu-200-degree; lona lanelisa ngemibili, kodwa liyisakaza kubanga elicishe libe ngu-350.
Yini eyisipesheli ngokubona kuka-ihhashi?
- Inkambu ecishe ibe ngu-360°
- Izindawo ezimbili ezingabonakali: ngaphambili nangemuva
- Ukubona okuhle ebusuku
