Hoʻoponopono nā leki makaʻala i nā hewa refractive ma ke kūlou ʻana (refracting) i ke kukui i kona hele ʻana i ka lens. Hōʻike ʻia ka nui o ka hiki ke kulou māmā (ka mana lens) e hāʻawi i ka ʻike maikaʻi ma ka ʻōlelo kuhikuhi i hāʻawi ʻia e kāu mea ʻike.
Ua ana ʻia nā hewa refractive a me nā mana lens e pono ai e hoʻoponopono iā lākou i nā ʻāpana i kapa ʻia ʻo dioptres (D). Inā he makapō haʻahaʻa ʻoe, ʻōlelo paha kāu ʻōlelo leka uila -2.00 D. Inā he myopic nui ʻoe, ʻōlelo paha -8.00 D.
Inā ʻike lōʻihi ʻoe, pono ʻoe i nā lens "plus" (+), ʻoi aku ka mānoanoa ma waena a ʻoi aku ka lahilahi ma ka lihi.
Hiki ke mānoanoa a kaumaha ke aniani maʻamau a i ʻole nā aniani plastik no ka nui o ka ʻike pōkole a lōʻihi paha.
ʻO ka mea pōmaikaʻi, ua hana nā mea hana i nā ʻano mea hou "kiʻekiʻe-index" lens lens e hoʻohuli pono i ka mālamalama.
ʻO ia ka mea hiki ke hoʻohana ʻia nā mea liʻiliʻi i ka lens-index kiʻekiʻe e hoʻoponopono i ka nui like o ka hewa refractive, i mea e ʻoi aku ka lahilahi a me ka māmā o nā lens plastik kiʻekiʻe ma mua o ke aniani maʻamau a i ʻole nā lens plastik.
ʻO nā pono o nā lens kiʻekiʻe-index
ʻoi aku ka lahilahi
Ma muli o ko lākou hiki ke hoʻopōmaikaʻi ʻoi aku ka maikaʻi o ka māmā, ʻoi aku ka lahilahi o nā ʻaoʻao kiʻekiʻe-index no ka ʻike pōkole ma mua o nā lens me ka mana kuhikuhi like i hana ʻia me nā mea plastik maʻamau.
Māmā
Pono nā ʻaoʻao ʻoi aku ka liʻiliʻi o nā mea lens, e hōʻemi ana i ke kaumaha holoʻokoʻa o nā lens. ʻOi aku ka māmā o nā aniani i hana ʻia me ka plastic kiʻekiʻe ma mua o nā lens like i hana ʻia me ka plastic maʻamau, no laila ʻoi aku ka ʻoluʻolu o ke komo ʻana.
A ʻo ka hapa nui o nā lens kiʻekiʻe he hoʻolālā aspheric, e hāʻawi iā lākou i kahi hiʻohiʻona slimmer, ʻoi aku ka maikaʻi a hōʻemi i ka hiʻohiʻona nui i hana ʻia e nā lens maʻamau i nā ʻōlelo kuhikuhi ikaika loa.
Nā koho lens kiʻekiʻe
Loaʻa nā lens plastik kiʻekiʻe i kēia manawa i nā ʻano helu refractive like ʻole, maʻamau mai ka 1.60 a i ka 1.74. Hiki ke ʻoi aku ka lahilahi o nā lens me ka index refractive o 1.60 & 1.67 ma ka liʻiliʻi he 20 pakeneka ma mua o nā lens plastik maʻamau, a ʻo 1.71 a i ʻole ke kiʻekiʻe ma kahi o 50 pakeneka ʻoi aku ka lahilahi.
Eia kekahi, ma ka ʻōlelo maʻamau, ʻoi aku ka kiʻekiʻe o ka index, ʻoi aku ka kiʻekiʻe o ke kumukūʻai lens.
Hoʻoholo pū kāu ʻōlelo kuhikuhi i ke ʻano o nā mea kiʻekiʻe-index āu e makemake ai no kāu lens. Hoʻohana mua ʻia nā mea kikoʻī kiʻekiʻe no nā ʻōlelo kuhikuhi ikaika loa.
ʻO ka hapa nui o nā hoʻolālā lens kaulana a me nā hiʻohiʻona - me Dual Aspheric, Progressive, Bluecut Pro, Prescription tinted, a me nā lens photochromic spin-coating hou - aia i nā mea kiʻekiʻe-index. Welina mai e kaomi i kā mākou ʻaoʻao mahttps://www.universeoptical.com/armor-revolution-product/e nānā i nā kikoʻī hou aku.
