Indlela ezibona ngayo
inja ibona kanjani umhlaba?
Ayiboni obomvu–oluhlaza, yakhelwe ukunyakaza nokuhwalala
Hamba eceleni kwenja ntambama uzothola ukuthi nihlala emhlabeni owodwa kodwa yona iwufunda ngendlela ehluke kakhulu. I-retina yayo idela imininingwane ecolekile kanye nombala ophelele ukuze ithole into engasiza umzingeli nomngane: umbono obanzi, olambele ukunyakaza, ovuka ekukhanyeni okuncane. Okubomvu nokuluhlaza kufiphala kube ngokusaphuzi oludakekile, kodwa ibhola eliphonswayo noma ukubaleka kwengwejeje kuyagqama masinyane.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-inja kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-12 ngedigri (20/50), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-245°.
inja ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-12 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-5 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 inja engayibona?
Ibona okuluhlaza sasibhakabhaka nokuphuzi; ayihlukanisi obomvu nokuluhlaza (kokubili kubukeka njengokungwevu okuphuzi). Ithola ibhola elibomvu otshanini ngephunga nokunyakaza, hhayi ngombala.
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone) + i-retina egcwele amaseli e-rod
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka-mfusa)429 nm
- L (ophuzi-luhlaza)555 nm
inja ibona kanjani ebumnyameni?
I-tapetum lucidum + i-retina ebuswa amaseli e-rod: idinga cishe ingxenye eyodwa kwezine yokukhanya okudingwa umuntu.
Ukubona kuka-inja kuqhathaniswa kanjani nokomuntu?
Imininingwane ecolekile yenja ifika cishe ku-20/50, kude ngale kwe-20/20 yakho, futhi isebenza ngemibala emibili eyinhloko esikhundleni semithathu. Lokho ekulahlekelwayo ebuchwepheshweni ikubuyisela emuva ebusuku: ikota yokukhanya kwakho yanele, kubanga elingu-245-degree.
Yini eyisipesheli ngokubona kuka-inja?
- Ukubona okuhle kakhulu ukunyakaza
- Ukubona okuhle ekukhanyeni okuncane
- Inkambu ebanzi ejikelezayo
