Pehea ka ike ana o na ilio?

ʻO ke kumumanaʻo e ʻike nā ʻīlio i nā mea āpau e like me ke kiʻiʻoniʻoni ʻeleʻele a me ke keʻokeʻo i hōʻole ʻia e nā mea noiʻi ʻAmelika i ka makahiki 2012. Ua ʻike ʻia ʻo ka ʻoiaʻiʻo, ʻike nā holoholona i nā kala, ʻoiai ʻoi aku ka liʻiliʻi ma mua o nā kānaka.

ʻIke kala a me ka myopia

ʻO ka hoʻonui ʻana i ka biology e hiki ai iā ʻoe ke hoʻomaopopo pono i ka ʻike ʻana o ka ʻīlio i ka honua a puni ia. ʻO nā photoreceptors ke kuleana no ka ʻike ʻana i nā kala i loko o ke ʻano o ka maka: ʻo ia nā koʻokoʻo a me nā cones ma ka retina, i loaʻa nā inoa ma muli o ko lākou ʻano. ʻEkolu ʻano cones ma ka retina o ka maka o ke kanaka, a ua ʻae lākou iā mākou e ʻike i nā aka o ka ʻulaʻula, ka ʻōmaʻomaʻo, a me ka uliuli.

Hoʻonohonoho ʻokoʻa ka maka o ka ʻīlio: no ka laʻana, ʻelua wale nō ʻano cones ma ka retina, a no kēia kumu, ʻaʻole hiki i nā holoholona ke hoʻokaʻawale i waena o ka melemele-'ōmaʻomaʻo a me ka ʻulaʻula-ʻalani.

Ua like ke kiʻi o ka honua a nā ʻīlio e ʻike ai me ka ʻike ʻana o ka poʻe makapō kala i ka honua.

ʻO kahi laʻana, ʻaʻole paha e ʻike ka puaʻa i ka pōpō a i ʻole kahi pāʻani ʻulaʻula i ka mauʻu. Eia naʻe, hiki mai ke ʻano honi i ka hoʻopakele: hiki i ka ʻīlio ke honi iā ​​lākou ma ke ʻala.

Akā naʻe, ʻaʻole kēia wale nō ka ʻokoʻa ma waena o ka ʻike kanaka a me ka ʻīlio. E like me ka mea i ʻike ʻia, ʻike iki kēia mau holoholona i ke kiʻi o ka honua ma mua o ke kanaka. Aia nō ke kumu i ke ʻano o nā kino o ka hihiʻo. ʻO ke kiko melemele ke kuleana no ka mālamalama a me ka olinolino o ke kiʻi i ʻike ʻia e ke kanaka. ʻAʻole loaʻa kēia wahi i ka ʻīlio, no laila ʻaʻole ʻike maikaʻi nā holoholona i nā kikoʻī. Inā hiki i ke kanaka me ka maka maikaʻi ke heluhelu i ka laina ʻumi o ka papa ʻike, a laila hiki i ka ʻīlio ke ʻike i ke kolu. Akā no nā holoholona, ​​ʻaʻole koʻikoʻi ka ʻike maka e like me ka hiki ke ʻike i kahi mea i loaʻa i ka manawa.

Kahua ʻike a me ka hahai holoholona pō

He ʻīlio ka ʻīlio, ʻo ia ke kumu e pono ai ke ʻike i ka pōʻeleʻele. A ʻoiaʻiʻo, i ka pō, ʻoi aku ka maikaʻi o kēia mau holoholona ma mua o ke kanaka a ʻike i nā ʻano o ka hina hina. ʻO kēia ma muli o ke ʻano o ke ʻano o nā mea ʻike maka o ka ʻīlio: ʻo nā photoreceptors like - nā lāʻau - ke kuleana no ka naʻau o nā maka i ka pōʻeleʻele, a ʻoi aku ka nui o lākou ma ka retina i loko o kahi ʻīlio ma mua o ke kanaka. No laila, ʻoiai i ka pō, ʻoluʻolu kāu pipi.

ʻO ka mea mahalo, ʻike ʻokoʻa nā ʻelele o nā ʻano like ʻole i ka honua. Aia ke kumu ma ke kahua o ka ʻike. ʻO nā ʻīlio hahai holoholona, ​​e like me nā beagles, me nā maka ma kahi mamao aku, he ākea ākea ka ʻike, aʻo nā ʻīlio me nā maka pili kokoke, e like me nā pugs a i ʻole nā ​​​​Pekingese, he wahi ākea o ka ʻike.

Pehea e hoao ai i ka maka o ka ilio?

ʻAʻole ia he mea huna e hiki ke hoʻopōʻino ka maka o ka ʻīlio me ka makahiki. Eia nō naʻe, aia kekahi mau kumu ʻē aʻe e kōkua i ka ulu ʻana o nā maʻi ophthalmic. Hiki i ka mea mālama pono ke ʻike i nā hōʻailona mua o ka hōʻino ʻana i ka ʻīlio:

• Nā maka ʻulaʻula a ʻulaʻula paha;
• ʻO ke ʻano o nā mea huna;
• ʻO ka ʻili ʻana, ka mea e ʻūleʻa pinepine ai ka ʻīlio i kona mau maka me kona mau wāwae.

ʻO kahi hōʻailona koʻikoʻi o ka hōʻino ʻana i ka ʻike ʻana o ka ʻīlio ʻo ia ka orientation ma ke ākea. Inā hāʻule ka pipi ma luna o nā mea, ʻaʻole ʻike i nā pilikia, a i ʻole e nānā ʻia me he mea lā ma o lākou, pono ke kūkākūkā me ka mea lapaʻau.
