Nui nā poʻe i hoʻohana i nā aniani no nā makahiki
Aia paha nā kānalua penei:
ʻO ka hoʻohana ʻana i nā aniani no ka lōʻihi, ʻaʻole maopopo i ka hoʻokaʻawale ʻana o nā lens
Myopia a me hyperopia?He aha nā manaʻo hoʻokahi a me nā manaʻo nui?
ʻAʻole hiki i ka naʻaupō ke haʻi i ka ʻokoʻa
ʻOi aku ka pilikia o ke koho ʻana i nā lens:
He aha ke ʻano lens kūpono iā ʻoe?
Aia nā ʻano hana like ʻole?He aha nā hiʻohiʻona e pono ai iaʻu?
Aia nā ʻano lens a pau;
Inā hoʻokaʻawale ʻia ka lens mai ka nānā ʻana, hiki ke hoʻokaʻawale ʻia i ka lens focal hoʻokahi (monophoto), nā lens focal pālua, nā lens multifocal.
ʻO nā lens progressive multifocal, ʻike ʻia hoʻi ʻo nā lens holomua, he mau kiko kikoʻī ma ka lens.
I kēia lā e kamaʻilio mākou e pili ana i nā lens progressive multifocal
He aha ka lens multifocal holomua?
ʻO nā aniani multifocal holomua, he nui nā kiko kiko ma ka lens hoʻokahi i ka manawa like, e hoʻololi mālie mai kahi mamao ma luna o ka lens a i kahi kokoke i lalo.
Ua māhele ʻia ka loaʻa ʻana o nā degere he nui ma ka lens hoʻokahi i ʻekolu mau ʻāpana: mamao, waena a kokoke:
1, ka ʻaoʻao mamao o luna
Hoʻohana ʻia no ka ʻike mamao lōʻihi, e like me ka pāʻani, hele wāwae, etc
2, waena a i ka apana waena
No ka ʻike mamao waena, e like me ka nānā ʻana i ke kamepiula, ke nānā ʻana i ke TV, etc
3. Nānā haʻahaʻa kokoke i kahi
Hoʻohana ʻia no ka nānā ʻana, e like me ka heluhelu puke, nūpepa, etc
No laila, ʻo ka ʻaʻahu wale ʻana i nā aniani, hiki ke hoʻokō i ke koi mamao, ʻike, ʻike kokoke i ka hihiʻo.
Nā hanana physiological maʻamau:
ʻO Presbyopia, ka mea e ʻike mālie ʻia me ka piʻi ʻana o ka makahiki, ʻike ʻia ma ke ʻano he polū a hiki ʻole ke ʻike i nā mea ma kahi kokoke.ʻO kēia kūlana e hōʻemi i ka maikaʻi o ka hana a pili i ka maikaʻi o ke ola.
ʻO nā lens multifocal holomua kahi hopena maikaʻi i kēia pilikia
Me ka hana maikaʻi loa
Nui ke aloha a ʻimi ʻia mai ka papa inoa ʻana
