Indlela ezibona ngayo
inkukhu ibona kanjani umhlaba?
I-tetrachromat ye-UV — umbala ocebile kunowakho
Kuningi okwenzeka ngemuva kwamehlo enkukhu kunalokho udumo lwayo olukusho. Iyi-tetrachromat enamakhoni ombala amane kanye namaconsi wamafutha amancane asebenza njengezihlungi zombala, eyinika i-palette ecebe kuneyethu neyeqela ku-ultraviolet. Ize icubungule isibhakabhaka esingaphezulu nomhlaba ongezansi ngezindawo ezehlukene zeso ngalinye.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-inkukhu kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-7 ngedigri (20/86 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-300°.
inkukhu ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-7 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-9 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 inkukhu engayibona?
Icebile kunobomuntu, inesiteshi se-UV; ibona izimpawu ze-UV zezimpaphe ezingabonakali kithi futhi icubungula izindawo ezehlukene ze-retina zesibhakabhaka nomhlaba.
Ama-photoreceptor
I-Tetrachromat (amaseli e-cone ama-4) + amaseli e-cone amabili + amaconsi amafutha
Iziqongo zokuzwela kwama-cone
- UV/mfusa415 nm
- S (oluhlaza sasibhakabhaka)455 nm
- M (oluhlaza)508 nm
- L (obomvu)571 nm
inkukhu ibona kanjani ebumnyameni?
Isebenza emini; imbi ebusuku.
Ukubona kuka-inkukhu kuqhathaniswa kanjani nokomuntu?
Imininingwane ecolekile yenkukhu, eseduze ku-20/86, iluvivi kune-20/20 yakho. Noma kunjalo, ibona umbala wesine oyinhloko ne-ultraviolet ongenakufinyelela kuyo, futhi amehlo ayo aqhaqhazela ngokushesha, abamba ukunyakaza okusheshayo obekungaba luvivi kuwe.
Yini eyisipesheli ngokubona kuka-inkukhu?
- Ibona i-ultraviolet
- Izihlungi zombala zamaconsi amafutha
- Ukuhlanganisa okuphezulu kokuqwayiza (~90 Hz)
Imithombo yesayensi
- Osorio, Vorobyev & Jones (1999)
- Bowmaker et al. (1997)
