Hoʻoponopono nā aniani maka aniani i nā hewa refractive ma ke kulou ʻana (refracting) i ka mālamalama i kona hele ʻana ma o ka aniani. ʻO ka nui o ka hiki ke kulou i ka mālamalama (mana aniani) e pono ai e hāʻawi i ka ʻike maikaʻi e hōʻike ʻia ma ke kauoha aniani i hāʻawi ʻia e kāu kauka maka.
Ua ana ʻia nā hewa refractive a me nā mana lens e pono ai e hoʻoponopono iā lākou ma nā anakahi i kapa ʻia ʻo dioptres (D). Inā he pōkole iki kou ʻike maka, e ʻōlelo paha kāu kauka lens -2.00 D. Inā he myopic loa kou, e ʻōlelo paha -8.00 D.
Inā he maka lōʻihi kou, pono ʻoe i nā aniani "plus" (+), ʻoi aku ka mānoanoa ma ke kikowaena a me ka lahilahi ma ka lihi.
ʻO nā aniani aniani a palaki paha maʻamau no ka ʻike pōkole kiʻekiʻe a i ʻole ka ʻike lōʻihi hiki ke mānoanoa a kaumaha loa.
ʻO ka mea pōmaikaʻi, ua hana nā mea hana i nā ʻano mea aniani plastik "kiʻekiʻe" hou e pelu pono ana i ka mālamalama.
ʻO ke ʻano kēia, ʻoi aku ka liʻiliʻi o ka mea hiki ke hoʻohana ʻia i loko o ka lens index kiʻekiʻe e hoʻoponopono i ka nui like o ka hewa refractive, ka mea e hoʻolilo ai i nā aniani palaki index kiʻekiʻe i lahilahi a māmā hoʻi ma mua o ke aniani a i ʻole nā aniani palaki maʻamau.
Nā Pōmaikaʻi o nā aniani kuhikuhi kiʻekiʻe
Lahilahi
Ma muli o ko lākou hiki ke pelu i ka mālamalama me ka ʻoi aku ka maikaʻi, ʻoi aku ka lahilahi o nā ʻaoʻao o nā aniani kiʻekiʻe-index no ka pōkole o ka maka ma mua o nā aniani me ka mana kuhikuhi like i hana ʻia me ka mea palaki maʻamau.
Māmā
ʻOi aku ka māmā o nā aniani i hana ʻia me ka palakika kiʻekiʻe ma mua o nā aniani like i hana ʻia me ka palakika maʻamau, no laila ʻoi aku ka ʻoluʻolu o ke komo ʻana.
A ʻo ka hapa nui o nā aniani index kiʻekiʻe he hoʻolālā aspheric ko lākou, ka mea e hāʻawi iā lākou i kahi ʻano lahilahi a ʻoi aku ka nani a hoʻemi i ka nānā nui ʻia e hana ai nā aniani maʻamau i nā kauoha ʻike lōʻihi ikaika.
Nā koho aniani kuhikuhi kiʻekiʻe
Loaʻa i kēia manawa nā aniani palaki kiʻekiʻe-index i nā ʻano ʻokoʻa like ʻole o nā refractive indices, maʻamau mai 1.60 a 1.74. ʻO nā aniani me ka refractive index o 1.60 a me 1.67 hiki ke liʻiliʻi he 20 pakeneka ka lahilahi ma mua o nā aniani palaki maʻamau, a ʻo 1.71 a ʻoi aku paha hiki ke ma kahi o 50 pakeneka ka lahilahi.
Eia kekahi, ma ke ʻano laulā, ʻo ke kiʻekiʻe o ka helu kuhikuhi, ʻo ke kiʻekiʻe o ke kumukūʻai o nā aniani.
Hoʻoholo pū kāu kuhikuhi maka aniani i ke ʻano o ka mea kiʻekiʻe-index āu e makemake ai no kāu aniani. Hoʻohana nui ʻia nā mea kiʻekiʻe loa no nā kuhikuhi ikaika loa.
Loaʻa ka hapa nui o nā hoʻolālā a me nā hiʻohiʻona lens kaulana o kēia mau lā - me Dual Aspheric, Progressive, Bluecut Pro, Prescription tinted, a me nā lens photochromic Spin-coating hou - i nā mea kiʻekiʻe-index.
