Indlela ezibona ngayo
ingwenya ibona kanjani umhlaba?
Umudwa obukhali odabula emngceleni wamanzi
Ingwenya ecwathile emgceleni wamanzi ihlonyiswe amehlo afanele ngempela umsebenzi. Umdwebo ovundlile wombono ocijile udabula i-retina yayo, uyinika ibhande elicacile, elibanzi ngqo endaweni yamanzi lapho inyamazane iza khona ukuzophuza. Inhlamvu yeso emise okoluvo kanye nongqimba olukhanyayo bese kuguqula lawo mehlo abe ngamathuluzi anamandla okuzingela ebusuku.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ingwenya kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-8.8 ngedigri (20/70), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-270°.
ingwenya ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-8.8 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-7 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 ingwenya engayibona?
Umbala olinganiselwe wama-cone amathathu, obuthakathaka kokubomvu; ocacile kuwo wonke umkhathizwe, ofiphele ngenhla nangaphansi.
Ama-photoreceptor
Ama-pigment amathathu ama-cone (umbala olinganiselwe) + umugqa ovundlile onobukhali obukhulu + i-tapetum lucidum
Iziqongo zokuzwela kwama-cone
- S (oluhlaza sasibhakabhaka)443 nm
- M (oluhlaza)535 nm
- L (obomvu)566 nm
ingwenya ibona kanjani ebumnyameni?
Kuhle kakhulu; isikhala esiqondile esiyisikwele nene-tapetum lucidum ukuze izingele ebusuku.
Ukubona kuka-ingwenya kuqhathaniswa kanjani nokomuntu?
Ingwenya ibona cishe ku-20/70 kune-20/20 yakho futhi, njengawe, inezinhlobo ezintathu zamakhoni. Ekuskeneni umkhathizwe umdwebo wayo ovundlile wombono ocijile udlula iso lakho, futhi umbono wayo wasebusuku uwudlula kakhulu owakho.
Yini eyisipesheli ngokubona kuka-ingwenya?
- Umugqa ovundlile onobukhali obukhulu
- Isikhala esiqondile esiyisikwele
- Ukukhanya kwe-tapetum emehlweni
