Indlela ezibona ngayo
iphengwini ibona kanjani umhlaba?
Elungiselelwe okuluhlaza okwesibhakabhaka emhlabeni wangaphansi kwamanzi
Amehlo ephengwini alungiselelwe ulwandle olizingela kulo, hhayi ugu oludunusela kulo. Ukuzwela kwalo umbala kuthambekele kuma-wavelength aluhlaza okwesibhakabhaka nawansomi asinda ngaphansi kwamanzi, kuyilapho okubomvu, umbala wokuqala ogwinywa amanzi olwandle, cishe akubonakali. Libona ngokucija emoyeni nasemanzini, impilo enzima ephindwe kabili kunoma yimaphi amehlo.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-iphengwini kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-13 ngedigri (20/46 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-240°.
iphengwini ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-13 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 iphengwini engayibona?
Ithambekele kokuluhlaza sasibhakabhaka-mfusa; obomvu obuthaka. Kwenzelwe ukuqhathanisa emanzini, lapho ukukhanya okubomvu kumunceka emamitheni ambalwa.
Ama-photoreceptor
Amaseli e-cone ashiyele kokuluhlaza sasibhakabhaka/mfusa (ukuzwela okuncane emaza amade)
Iziqongo zokuzwela kwama-cone
- V (mfusa)403 nm
- S (oluhlaza sasibhakabhaka)450 nm
- M (oluhlaza)543 nm
iphengwini ibona kanjani ebumnyameni?
Kuhle; izingela ejulile ekukhanyeni okuncane.
Ukubona kuka-iphengwini kuqhathaniswa kanjani nokomuntu?
Iphengwini libona cishe ku-20/46 kune-20/20 yakho, umbala walo uthambekele kokuluhlaza okwesibhakabhaka nawansomi okubomvu obubuthakathaka. Ngaphansi kwamanzi, lapho okwakho kuba luvivi kabi ngaphandle kwesifonyo, umbono walo uhlala ucacile.
Yini eyisipesheli ngokubona kuka-iphengwini?
- Ukubona okushiyele kokuluhlaza sasibhakabhaka/mfusa
- Icacile emoyeni nasemanzini
- Ukuzwela obomvu okuncane

Khomba ikhamera yakho kunoma yini bese ubuka umhlaba uguquka ube ukubona kwalesi silwane ngesikhathi sangempela.
