ʻO nā lens āu e pono aikou mau anianie hilinaʻi ʻia ma kāu ʻōlelo kuhikuhi maka aniani.Ma mua o kou kūʻai ʻana i nā aniani hou, e hoʻonohonoho i kahi hoʻokolokolo maka me kāu kauka maka.Na lākou e hoʻoholo i ke ʻano o ka hoʻoponopono ʻike āu e pono ai.
ʻIke hoʻokahi
ʻO nā lens hihiʻo hoʻokahi ke ʻano haʻahaʻa loa a maʻamau o nā maka aniani.Loaʻa iā lākou ka māhele ʻike nui loa no ka mea hoʻoponopono wale lākou i ka ʻike ma kahi mamao kikoʻī (ma kahi mamao a kokoke paha).Hoʻokaʻawale kēia iā lākou mai nā lens multifocal i wehewehe ʻia ma lalo nei.
Hiki paha i kāu kauka ke kuhikuhi i nā lens hihiʻo hoʻokahi inā loaʻa iā ʻoe kekahi o kēia:
ʻIke kokoke
ʻO ka ʻike maka
Astigmatism
Bifocals
ʻO nā lens bifocal he multifocal, ʻo ia hoʻi he ʻelua "mana" like ʻole i loko o lākou.Hoʻoponopono kēia mau ʻāpana like ʻole o ka lens i ka ʻike mamao a me ka ʻike kokoke.
Ua kuhikuhi ʻia nā lens bifocal no ka poʻe me nā pilikia ʻike lehulehu.
Trifocals
Ua like nā lens trifocal me ka bifocals.Akā he mana hou ko lākou e hoʻoponopono ai i ka ʻike waena.No ka laʻana, hiki ke hoʻohana ʻia ka ʻāpana waena e nānā i kahi pale kamepiula.
ʻO ka hemahema nui o nā bifocals a me nā trifocals he laina ʻokoʻa ko lākou ma waena o kēlā me kēia kahua o ka ʻike.Hana kēia i nā ʻāpana o ka lens i ka ʻike ʻokoʻa loa.Maʻa ka hapa nui o ka poʻe i kēia a ʻaʻohe pilikia.Akā ʻo kēia drawback ua alakaʻi i ka hoʻomohala ʻana i nā lens holomua, e like me nā holomua.
Holomua
ʻO nā lens holomua kekahi ʻano o ka lens multifocal.Hana lākou no kēlā me kēia mea e pono ai nā bifocals a i ʻole trifocals.Hāʻawi nā lens holomua i ka hoʻoponopono like no ka ʻike kokoke, waena, a me ka mamao.Hana lākou i kēia me ka ʻole o nā laina ma waena o kēlā me kēia ʻāpana.
Nui ka poʻe makemake i kēia mau lens multifocal no ka mea ʻoi aku ka maʻalahi o ka hoʻololi ʻana ma waena o nā kahua o ka ʻike.
