Ua like nā maka o nā pōpoki me ko ka poʻe akā ʻo ka evolution ka mea i nānā i ka nānā ʻana i ka hoʻomaikaʻi ʻana i ka hana hopu holoholona o kēia mau holoholona, nā mea ʻaihue. Makemake nā poʻe hahai holoholona maikaʻi, pono ka pōpoki e hoʻomaopopo i ka neʻe ʻana o nā mea a puni lākou ke liʻiliʻi iki ka malamalama a ʻaʻole ia he mea nui e hoʻokaʻawale lākou i ka nui o nā kala e ola ai, akā ʻaʻole ia he ʻoiaʻiʻo ʻike wale lākou i ka ʻeleʻele a me ke keʻokeʻo. I ka ʻoiaʻiʻo, ʻike lākou i nā mea ʻoi aku ka maikaʻi ma mua o kā mākou e pili ana i ka nānā ʻana i nā mea kokoke, akā naʻe, he māla nui ko lākou o ka ʻike ma kahi mamao aku a hiki ke ʻike i ka pouli.
inā makemake ʻoe e ʻike pehea ʻike nā pōpoki, e hoʻomau i ka heluhelu ʻana i kēia ʻatikala PeritoAnimal kahi e hōʻike ai mākou iā ʻoe i kekahi mau mea nui e noʻonoʻo ai i ka ʻike ʻana pehea e ʻike ai nā pōpoki.
ʻOi aku ka nui o nā maka o nā pōpoki ma mua o mākou
I mea e maopopo ai i ka ʻike ʻana o nā pōpoki, pono mākou e nānā i ka loea pōpoki a me ka mea ʻepekema o ke Kulanui o Bristol ʻo John Bradshaw, nāna i ʻōlelo he nui ka maka o nā pōpoki ma mua o ko ke kanaka. ma muli o kona ʻano predatory.
ʻO ka ʻoiaʻiʻo o ka mua o nā felines (nā pōpoki hihiu) pono e ʻimi holoholona i hiki iā lākou ke hānai a hoʻolōʻihi i kēia hana no ka nui o nā hola o ka lā, ua hoʻololi i ko lākou mau maka a hoʻonui i ka nui, e hoʻonui ana iā lākou ma mua o kēlā. nā kānaka, a me kahi e waiho ai i mua o ke poʻo (binocular vision) e hoʻopuni ai i kahi māla nui o ka hihiʻo e like me nā mea hōkai maikaʻi. pōpoki maka nui loa i ka hoʻohālikelike ʻia i ko lākou mau poʻo inā mākou e hoʻohālikelike iā lākou me kā mākou kaulike.
ʻIke nā pōpoki i nā manawa he 8 ma mua o ka mālamalama o ke kukui
Ma muli o ka pono e hoʻolōʻihi i ka manawa ʻimi holoholona o nā pōpoki hihiu i ka pō, ua hoʻomohala nā mea mua o nā pōpoki kūloko a ʻike ka pō ma waena o 6 a 8 mau manawa ʻoi aku ka maikaʻi ma mua o nā kānaka. Hiki iā lākou ke ʻike maikaʻi ma ke kukui liʻiliʻi a ʻo kēia ke kumu o ka nui o nā photoreceptors i ka retina.
Hoʻohui, loaʻa i nā pōpoki ka mea i kapa ʻia tapetum lucidum, me ʻōpala o nā maka paʻakikī e hōʻike i ka mālam ma hope o ke komo ʻana i kahi nui a ma mua o ka hōʻea ʻana i ka retina, kahi e loaʻa ai iā lākou ka ʻike maka i ka pouli a me ko lākou mau maka e ʻālohilohi i ka mālamalama ke kukui. No laila ke paʻi mākou i kahi kiʻi o lākou i ka pō, ʻālohilohi nā maka o nā pōpoki. No laila, ʻo ka liʻiliʻi o ka mālamalama, ʻike ʻia nā pōpoki ʻoi aku ka maikaʻi i ka hoʻohālikelike ʻia me nā kānaka, akā ma ka ʻaoʻao ʻē aʻe, ʻike maikaʻi ʻole nā felines i ke ao ma muli o ka tapetum lucidum a me nā hunaola photoreceptor, i mea e kaupalena ʻia ai kāu hihi e ke komo ʻana i ka mālamalama i ka lā.
ʻIke nā pōpoki i ka blur hou i ke ao
E like me ka mea i ʻōlelo ʻia ma mua, ʻokoʻa nā hunaola receptor cells kuleana no ka hihi o nā pōpoki mai kā mākou. ʻOiai like nā pōpoki a me nā kānaka i ka ʻano like o nā photoreceptors, nā ʻone no ka hoʻokaʻawale ʻana i nā waihoʻoluʻu i ke kukui ʻōlinolino a me nā koʻokoʻo no ka ʻike ʻana i ka ʻeleʻele a me ke keʻokeʻo i ka mālamalama o ka mālamalama, ʻaʻole like ke ʻano o kēia mau mea: i ka maka o nā pōpoki e hoʻomalu i nā koʻokoʻo. A ʻaʻole wale kēlā, ʻaʻole pili pono kēia mau koʻokoʻo me ke aʻalolo ocular a ʻo ka hopena, pili pololei me ka lolo e like me ke kanaka, hoʻohui mua lākou i kekahi i kekahi a hana i nā hui liʻiliʻi o nā hunaola photoreceptor. Ma ke ʻano he maikaʻi ka hihiʻo o nā pōpoki ke hoʻohālikelike ʻia me kā mākou, akā i ke ao ua kū ka ʻaoʻao a ʻo nā pōpoki i ʻike maka ʻole a liʻiliʻi hoʻi, no ka mea ʻaʻole e hoʻouna ka maka i ka lolo, ma o ke aʻalolo. . ocular, ka ʻike kikoʻī e pili ana i nā keena e hoʻonāukiuki hou aʻe ai.
ʻAʻole ʻike nā pōpoki i ka ʻeleʻele a me ke keʻokeʻo
I ka wā ma mua, ua manaʻo ʻia hiki i nā pōpoki ke ʻike wale i ka ʻeleʻele a me ke keʻokeʻo, akā ʻo kēia kaao ka moʻaukala i kēia manawa, no ka mea ua hōʻike ʻia kekahi mau noiʻi e hiki i nā pōpoki ke hoʻokaʻawale i kekahi mau waihoʻoluʻu i ke ala kaupalena a kaukaʻi ʻia i ke kukui ākea.
E like me ka mea i ʻōlelo ʻia, ʻo nā hunaola photoreceptor e mālama nei i ka ʻike ʻana i nā kala nā cones. Loaʻa i nā kānaka he 3 mau ʻano cone e kiʻi i ke kukui ʻulaʻula, ʻōmaʻomaʻo a me ka uliuli; ma ka ʻaoʻao ʻē aʻe, he mau cone wale kā nā pōpoki e hopu i ke kukui ʻōmaʻomaʻo a me ka uliuli. No laila, hiki ke ʻike i nā kala anuanu a hoʻokaʻawale i kekahi mau kala mehana e like me ka melemele akā ʻaʻole ʻike i ke kala ʻulaʻula a i kēia hihia ʻike ʻia he hina hina. ʻAʻole hiki iā lākou ke ʻike i nā kala e like me ka maikaʻi a māʻona e like me nā kānaka, akā ʻike lākou i kekahi mau kala e like me nā ʻīlio.
ʻO kahi mea e hoʻopili ai i ka hihiʻo o nā pōpoki he māmā, kahi mea e hoʻomālamalama ai i ka liʻiliʻi, hiki i nā maka pōpoki ke hoʻomaopopo i nā kala, ʻo ia ke kumu o felines ʻike wale i ka ʻeleʻele a keʻokeʻo i ka pouli.
Loaʻa i kahi pōpoki kahi ākea ākea o ka ʻike.
Wahi a ka mea pena a me ka mea noiʻi ʻo Nickolay Lamn o ke Kulanui o Pennsylvania, nāna i alakaʻi i kahi noiʻi e pili ana i ka ʻike feline me ke kōkua o kekahi mau ophthalmologists feline a me nā veterinarians, nā pōpoki. he kahua ʻike nui aʻe ma mua o ka poʻe.
He 200 kekelē o ka nānā o nā pōpoki, ʻoiai he 180-kekelē ke ʻano o ke kanaka, a ʻoiai heʻuʻuku ia, he helu nui ia i ka hoʻohālikelike ʻana i nā pae ʻike, no ka laʻana, i kēia mau kiʻi na Nickolay Lamn kahi e hōʻike ai ka luna. ka mea a ke kanaka e ʻike ai a hōʻike ka lalo i ka mea a ka pōpoki e ʻike ai.
ʻAʻole pili loa nā pōpoki
ʻO ka mea hope loa, e hoʻomaopopo pono ai i ka ʻike ʻana o nā pōpoki, pono mākou e nānā i ka ʻoi loa o ka mea a lākou e ʻike nei. Nui aʻe ka ʻike o ka poʻe i ka nānā ʻana i nā mea ma kahi kokoke no ka mea ʻoi aku ka liʻiliʻi o kā mākou ʻike ākea ma kēlā me kēia ʻaoʻao ma mua o nā pōpoki (20 ° i hoʻohālikelike ʻia me kā lākou 30 °). ʻO ia ke kumu e hiki ai iā mākou ke noʻonoʻo nui i kahi mamao o 30 mika a piʻi nā pōpoki i 6 mau mika e ʻike pono ai i nā mea. ʻO kēia ke kumu no ka nui o ko lākou mau maka a me ka liʻiliʻi o nā mākala i mua o mākou. Eia nō naʻe, ʻo ka nele o ka ʻike ākea e hāʻawi iā lākou i ka hohonu o ka māla, kahi mea nui loa no kahi mea ʻino maikaʻi.
I kēia mau kiʻi paʻi hōʻike mākou iā ʻoe i kahi hoʻohālikelike ʻē aʻe e ka mea noiʻi ʻo Nickolay Lamn e pili ana pehea mākou e ʻike ai i kahi kokoke (kiʻi kiʻekiʻe) a pehea e ʻike ai nā pōpoki (kiʻi lalo).
Inā ʻoe hoihoi e pili ana i nā pōpoki, heluhelu i kā mākou ʻatikala ma kā lākou hoʻomanaʻo.
