Indlela ezibona ngayo
ufudu lwasolwandle ibona kanjani umhlaba?
Umbala we-UV kuya kobomvu ngaphansi kwamagagasi
Ufudu lwasolwandle luphatha amehlo anombala emhlabeni oluhlaza okwesibhakabhaka-luhlaza, lubona kusukela ku-ultraviolet kuya ngokubomvu ngamakhoni afakwe izihlungi zamaconsi wamafutha anombala amancane. Lulungiselelwe ukukhanya kogu nolwandle olukhanyiswe inyanga, umbono walo luluqondisa kuwo wonke amalwandle. Lokho kuzwela kwakhona, ngokudabukisayo, yikho okwenza izibani ezingafanele ebhishi zingase zidukise amaphuphu alo.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-ufudu lwasolwandle kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-6 ngedigri (20/100 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-200°.
ufudu lwasolwandle ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-6 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-10 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 ufudu lwasolwandle engayibona?
Umbala obanzi, kusuka ku-UV kuya kobomvu; izwela amaza okukhanya kwasogwini nokwenyanga.
Ama-photoreceptor
I-Tetrachromat enamaconsi amafutha anemibala, ekwazi ukubona i-UV
Iziqongo zokuzwela kwama-cone
- UV/mfusa400 nm
- S (oluhlaza sasibhakabhaka)450 nm
- M (oluhlaza)502 nm
- L (obomvu)570 nm
ufudu lwasolwandle ibona kanjani ebumnyameni?
Kuhle kokuluhlaza sasibhakabhaka-luhlaza kolwandle oluvulekile.
Ukubona kuka-ufudu lwasolwandle kuqhathaniswa kanjani nokomuntu?
Imininingwane yofudu lwasolwandle icishe ibe ngu-20/100 kune-20/20 yakho, kodwa lubona i-ultraviolet ongeke ukubone futhi lulungiselelwe kahle ukukhanya okuluhlaza okwesibhakabhaka-luhlaza kwamanzi avulekile, lapho iningi lombono wakho wombala lungaphela khona.
Yini eyisipesheli ngokubona kuka-ufudu lwasolwandle?
- Ibona i-ultraviolet
- Izihlungi zombala zamaconsi amafutha
- Ikhangwa amaza athile
