ʻO nā Lenses Bifocals nā lens makaʻala i loaʻa nā ʻāpana hoʻoponopono ʻelua a hoʻohana mua ʻia no ka hoʻoponopono presbyopia. ʻO ka wahi kahi e hoʻoponopono ai nā bifocals i ka ʻike mamao, ua kapa ʻia ʻo ia he wahi ʻike mamao, a ʻo kahi e hoʻoponopono ai i kahi kokoke i kahi ʻike, ua kapa ʻia ʻo kahi kokoke i ka hihiʻo a me ka wahi heluhelu. ʻO ka mea maʻamau, ʻoi aku ka nui o ka ʻāpana mamao, no laila ua kapa ʻia ʻo ia ka ʻāpana nui, a ʻoi aku ka liʻiliʻi o kahi kokoke, i kapa ʻia ʻo ka ʻāpana ʻāpana.

ʻElua wale nō degere ma ka lens bifocales, i maheleia i ka malamalama luna a me ka malamalama lalo. ʻO ke kukui luna a me ke kukui haʻahaʻa hiki ke lilo i myopia, hyperopia, astigmatism, a me nā mea ʻē aʻe, akā ʻoi aku ka hohonu o ke kukui o luna ma mua o ke kukui o luna no ka myopia a ʻoi aku ka papau no ka ʻike maka.

Hoʻomohala ʻia ka holomua ma ke kumu o ke kukui pālua. ʻAʻole wale nā hiʻohiʻona o ke kukui pālua, me ke kukui o luna a me ke kukui lalo, akā loaʻa pū kekahi kaʻina hana ma waena. ʻO ke degere ma waena o ke kukui luna a me ke kukui lalo he kaʻina hoʻololi mālie.

Ma ka ʻili, ʻike ʻia ka ʻokoʻa ma waena o ke kukui pālua. Hiki ke ʻike ʻia ka laina hoʻokaʻawale a i ʻole ka hui ʻana ma waena o ke kukui o luna a me ke kukui haʻahaʻa, akā ʻaʻole hiki ke ʻike ʻia ka ʻili o ka lens holomua.

E pili ana ka Bifocal i ʻelua mana dioptric like ʻole ma ka lens hoʻokahi, ʻelua mana dioptriche dhāʻawi ʻia ma nā wahi like ʻole o ka lens, ʻo ka wahi i hoʻohana ʻia e ʻike i kahi mamao i kapa ʻia ʻo ka mamao mamao, aia ma ka hapa luna o ka lens; kapa ʻia ka wahi i ʻike ʻia ma kahi kokoke, aia ma ka hapa haʻahaʻa o ka lens.

ʻO nā mea maikaʻi o ka bifocals: Hiki iā ʻoe ke ʻike i nā mea ma kahi mamao ma o ka ʻāpana ʻike mamao loa o nā lens, a hiki iā ʻoe ke ʻike i nā mea ma kahi mamao kokoke ma o ka ʻāpana ʻike kokoke o nā lens like. ʻAʻole pono ʻoe e lawe i ʻelua mau makaaniani me ʻoe, a ʻaʻole pono ʻoe e hoʻololi ma waena o nā makaaniani mamao a kokoke pinepine.

Nā pōʻino o nā bifocals: ʻOi aku ka liʻiliʻi o ke kahua o ka nānā ʻana ma mua o nā lens ʻike hoʻokahi, ʻoi aku ka kokoke i ka ʻike. No ka laʻana, pono e hui pū ka heluhelu ʻana i nā puke a me nā nūpepa me nā neʻe poʻo. Loaʻa nā hemahema optical o ka lele ʻana a me ka neʻe ʻana o ke kiʻi, a aia kahi laina hoʻokaʻawale, kahi maʻalahi ke ʻike ʻia i ke komo ʻana. Hōʻike i ka makahiki me nā bifocals.
