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.
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
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
Ukubona ekukhanyeni okuncane
Mubi: yakhelwe ukukhanya kwemini, ngokungafani neningi lamagundane.
Uma kuqhathaniswa nokubona komuntu
Ingwejeje ibona cishe ku-20/300 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.
Izici eziphawulekayo
- Igundane elisebenza emini
- I-retina egcwele amaseli e-cone
- Inkambu ebanzi yokuthola izilwane ezizingelayo
Imibuzo evame ukubuzwa
ingwejeje ibona kanjani umhlaba?
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. I-dichromacy eluhlaza sasibhakabhaka-phuzi; ayiboni obomvu. Umbala omuhle wasemini kugundane.
Yimiphi imibala ingwejeje engayibona?
I-dichromacy eluhlaza sasibhakabhaka-phuzi; ayiboni obomvu. Umbala omuhle wasemini kugundane. I-Dichromat (izinhlobo ezi-2 zamaseli e-cone), egcwele amaseli e-cone (yasemini)
Ukubona kuka-ingwejeje kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-4 ngedigri (20/300 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/20). 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.
ingwejeje ibona kanjani ebumnyameni?
Mubi: yakhelwe ukukhanya kwemini, ngokungafani neningi lamagundane.
Yini eyisipesheli ngokubona kuka-ingwejeje?
Igundane elisebenza emini. I-retina egcwele amaseli e-cone. Inkambu ebanzi yokuthola izilwane ezizingelayo. Ngokungafani nabazala bayo begundane abathanda ubusuku, i-retina yengwejeje igcwele amakhoni kunama-rod. Iyingcweti yokukhanya kwemini, cishe ingelusizo ebumnyameni lapho igundane lichuma khona.
Ukubona kuka-ingwejeje kuqhathaniswa kanjani nokomuntu?
Ingwejeje ibona cishe ku-20/300 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.
