Indlela ezibona ngayo
uzekamanzi ibona kanjani umhlaba?
Mhlawumbe ama-opsin angu-30, ukunyakaza cishe 360°
Uzekamanzi uwumbulali wasemoyeni, futhi umbono wawo wakhelwe ukujaha. Amehlo ayinhlanganisela amalensi ayizinkulungwane ezingamashumi asonga cishe ngokuphelele ikhanda lawo, umnika umkhathi ocishe ube yindilinga ephelele yokubona, futhi ungaphatha kuze kufike ama-opsin ombala angamashumi amathathu ahlukene, ithuluzi lombala elicebe kunawo wonke elaziwayo embusweni wezilwane. Konke kulungiselelwe ukuvimbela inyamazane nokuyibamba emkhathini.
Bona ngamehlo azo
Umuntu ≈ 60 cpd (20/10)
Ukubona kuka-uzekamanzi kucace kangakanani?
Amehlo ayo ahlukanisa cishe ama-cycles angu-1.5 ngedigri (20/400 (est.)), kanti umuntu ufinyelela cishe ku-60 cpd (20/10). Ibanga layo lokubona lisabalala cishe ngo-360°.
uzekamanzi ubona kanjani umuntu?
Amehlo ayo ahlukanisa cishe imijikelezo engu-1.5 ngedigri, kanti awakho angu-60, ngakho ubuso kumele busondele cishe izikhathi ezingu-40 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 uzekamanzi engayibona?
Cishe inombolo enkulu kunazo zonke yezinhlobo zama-receptor ombala kunoma iyiphi isilwane, kanye nokubona i-UV nokukhanya okusabalalisiwe.
Ama-photoreceptor
Kufinyelela ku-~30 izinhlobo ze-opsin kuma-~28.000 omatidia; UV + polarization
Iziqongo zokuzwela kwama-cone
- UV350 nm
- Oluhlaza sasibhakabhaka440 nm
- Oluhlaza520 nm
- Obomvu620 nm
uzekamanzi ibona kanjani ebumnyameni?
Isebenza emini.
Ukubona kuka-uzekamanzi kuqhathaniswa kanjani nokomuntu?
Imininingwane ecolekile kazekamanzi iluvivi, cishe ku-20/400 kune-20/20 yakho. Kukho konke okunye uyakwedlula: cishe ama-360-degree kanye kanye, iziteshi zombala eziningi kakhulu, nokunyakaza okusheshayo okufundwa ngokushesha okuphindwe kaningi kunokulandela kweso lakho.
Yini eyisipesheli ngokubona kuka-uzekamanzi?
- Kufinyelela ku-~30 ama-opsin
- Ukubona okucishe kube ngu-360°
- Ukubona okukhulu kokunyakaza/kokuqwayiza (~300 Hz)
