He aha kāu e ʻike ai e pili ana i ka Interpupillary Distance!

Pehea e kapa ʻia ai nā makaaniani he kūpono? ʻAʻole pono e loaʻa kahi diopter pololei, akā pono e hana ʻia e like me ka mamao interpupillary pololei. Inā he hapa nui i ka mamao interpupillary, e ʻoluʻolu ʻole ka mea hoʻohana inā pololei ka diopter. No laila, no ke aha e hōʻoluʻolu ʻole ai ka mamao interpupillary? Me kēia nīnau, e kamaʻilio kākou e pili ana i kekahi ʻike e pili ana i ka mamao interpupillary.

• He aha ka mamao interpupillary?

ʻO ka mamao ma waena o nā kikowaena geometric o nā haumāna o nā maka ʻelua i kapa ʻia ʻo ka mamao interpupillary. Ma ka palapala kuhikuhi optometry, ʻo PD ka pōkole, a ʻo ka ʻāpana he mm. Aia wale nō ke hele ka laina o ka ʻike maka o nā maka ʻelua ma ke kikowaena optical o nā aniani aniani hiki ke hoʻohana ʻoluʻolu. No laila, i ka wā e hana ai i nā aniani, pono ʻoe e hoʻāʻo e hana i ka mamao kikowaena optical o nā aniani kokoke i ka mamao interpupillary o nā maka.

• Ka helu ana o ka mamao interpupillary?

No ka mea, huli ka maka o ke kanaka i loko i nā degere like ʻole ke nānā aku i nā mamao like ʻole. ʻO ka pili kokoke i ka nānā ʻia ʻana, ʻoi aku ka nui o ka hui ʻana o nā maka i loko. No laila, ma muli o ka mamao maka, ua māhele ʻia ka mamao interpupillary i ka mamao interpupillary mamao a me ka mamao interpupillary kokoke. Hoʻohana ʻia ka mamao interpupillary no nā aniani no ka nānā mamao; ka mamao interpupillary kokoke i hoʻohana ʻia no nā aniani kokoke, ʻo ia hoʻi ka mea maʻamau i kapa ʻia ʻo nā aniani pua.

• He aha nā ʻano ana i hoʻohana mau ʻia ma waena o ka interpupillary?

Ma ka optometry, hoʻohana pinepine ʻia nā mea hana e like me ka pupillary distance ruler, pupillary distance meter, a me ka computer refractor no ke ana ʻana. Ke lawe nei au i ke ʻano hoʻohana maʻamau interpupillary ruler ma ke ʻano he laʻana, e hōʻike pōkole wau i ke ʻano ana o ka mamao interpupillary:

1. Noho ka optometrist a me ke kumuhana i ke kiekie hookahi a he 40cm kaawale.

2. E kau i ka lula mamao interpupillary ma ke alo o ke alahaka o ka ihu o ke kumuhana a ma kahi mamao e like me ka mamao ma waena o nā maka aniani. Mai hili ʻia ma ke alo.

3. E nana ke kumuhana i ka maka hema o ka optometrist me na maka elua.

4. Pani ka optometrist i kona maka akau a nana me kona maka hema i mea e pili ana ka hoailona 0 o ka unahi interpupillary i ka lihi o loko o ka haumana o ka maka akau o ke kumuhana.

5. E mālama i ke kūlana o ka lula mamao interpupillary me ka loli ʻole, nānā ke kumuhana i ka maka ʻākau o ka optometrist me nā maka ʻelua, a pani ka optometrist i ka maka hema, a nānā me ka maka ʻākau. ʻO ka pālākiō kahi i hoʻolikelike ai ka lula mamao interpupillary me ka ʻaoʻao o waho o ka haumāna o ka maka hema o ke kumuhana ʻo ia ke ana ʻana i ka mamao interpupillary ma kahi mamao.

• No ke aha i pilikia ai ka hewa o ka mamao interpupillary i ka wā e hana ai nā aniani?

Ma hope o ka hoʻomaopopo ʻana i kekahi manaʻo maʻamau e pili ana i ka mamao interpupillary, e hoʻi kāua i ka nīnau hoʻomaka. No ke aha i pilikia ai ke komo ʻana i ka mamao interpupillary?

Ke hana ʻia nā lens ʻelua, loaʻa kahi hewa ma ka mamao interpupillary, no laila pono e loaʻa i hoʻokahi (a ʻelua) mau maka kahi i hiki ʻole ai ke kukui i loaʻa i ke koʻi ʻike ke hele ma waena o ke kikowaena optical o ka lens. I kēia manawa, ma muli o ka hopena prism o ka lens, ua hoʻololi ʻia ke kuhikuhi o ka mālamalama e komo ana i ka maka, a ʻo nā kiʻi mea i hana ʻia i nā maka ʻelua ʻaʻole e hāʻule i nā kiko kūpono, e hopena i ka ʻike pālua (ghosting). ʻO ka hopena, e hana koke ka lolo i kahi hoʻoponopono hoʻoponopono e hoʻoponopono i nā ʻiʻo extraocular a hoʻopau i ka diplopia. Inā hoʻomau kēia kaʻina hoʻoponopono, e hōʻeha ia i ka mea hoʻohana, a ʻoi aku ka nui o ka hewa, ʻoi aku ka hiki ʻole ke hoʻomanawanui.

Inā makemake ʻoe e ʻike hou aʻe e pili ana i nā ʻano aniani a me nā kūkākūkā ʻoihana, e ʻoluʻolu e kipa i kā mākou pūnaewele a e kelepona mai iā mākou i kēlā me kēia manawa.
