Indlela ezibona ngayo
ingwejeje ibona kanjani umhlaba?
Igundane elingavamile lasemini, elingaboni obomvu
Ingwejeje iyilelo gundane elingavamile eliphila ngokukhanya kwemini, futhi amehlo ayo akhelwe ukufana: agcwele amakhoni, aklanyelwe umhlaba okhanyayo, omatasa wokweqa phakathi kwamagatsha. Ibona okuluhlaza okwesibhakabhaka nokusaphuzi ngokusobala kodwa iyimpumputhe kokubomvu, futhi idela umbono wasebusuku cishe ngokuphelele ngokushintshanisa nokuqwashisa okucijile kwasemini phezulu esihlahleni.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ingwejeje kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-4 ngedigri (20/150 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-340°.
ingwejeje 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.
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 ingwejeje engayibona?
I-dichromacy eluhlaza sasibhakabhaka-phuzi; ayiboni obomvu. Umbala omuhle wasemini kugundane.
Ama-photoreceptor
I-Dichromat (izinhlobo ezi-2 zamaseli e-cone), egcwele amaseli e-cone (yasemini)
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)440 nm
- M (oluhlaza)543 nm
ingwejeje ibona kanjani ebumnyameni?
Mubi: yakhelwe ukukhanya kwemini, ngokungafani neningi lamagundane.
Ukubona kuka-ingwejeje kuqhathaniswa kanjani nokomuntu?
Ingwejeje ibona cishe ku-20/150 kune-20/20 yakho nemibala emibili kunemithathu. Ebusuku yenza kabi kunawe, wena okungenani ogcina ukubona okuthile, kodwa emini inkambu yayo ebanzi igcina iqaphile njalo oklebe abaphezulu.
Yini eyisipesheli ngokubona kuka-ingwejeje?
- Igundane elisebenza emini
- I-retina egcwele amaseli e-cone
- Inkambu ebanzi yokuthola izilwane ezizingelayo
