ʻElua wale nō kekelē ma ka lens bifocales, i māhele ʻia i ke kukui luna a me ke kukui haʻahaʻa. Hiki i ke kukui luna a me ke kukui haʻahaʻa ke myopia, hyperopia, astigmatism, a pēlā aku, akā ʻoi aku ka hohonu o ke kukui luna ma mua o ke kukui luna no ka myopia a ʻoi aku ka pāpaʻu no ka ʻike maka mamao.

Hoʻomohala ʻia ka holomua ma ke kumu o ke kukui pālua. ʻAʻole wale ia he mau ʻano o ke kukui pālua, me ke kukui luna a me ke kukui lalo, akā he kaʻina hana mālie hoʻi ma waena. ʻO ke kekelē ma waena o ke kukui luna a me ke kukui lalo he kaʻina hana hoʻololi mālie.

Ma ka ʻili, ua maopopo 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 o lalo, akā ʻaʻole hiki i ka ʻili o ka lens holomua ke ʻike i kekahi ʻokoʻa.

ʻO Bifocal e pili ana i ʻelua mau mana dioptric like ʻole ma ka lens like, ʻelua mau mana dioptriche dHoʻolaha ʻia ma nā wahi like ʻole o ke aniani, ʻo ka wahi i hoʻohana ʻia e ʻike mamao aku ua kapa ʻia ʻo ka ʻāpana mamao, aia ma ka hapalua o luna o ke aniani; ʻo ka wahi i hoʻohana ʻia e ʻike kokoke aku ua kapa ʻia ʻo ka ʻāpana kokoke, aia ma ka hapalua o lalo o ke aniani.

Nā Pōmaikaʻi o nā maka aniani bifocal: Hiki iā ʻoe ke ʻike i nā mea ma kahi mamao ma o ka ʻāpana ʻike mamao o kahi mau aniani ʻelua, a hiki iā ʻoe ke ʻike i nā mea ma kahi kokoke ma o ka ʻāpana ʻike kokoke o ka mau aniani like. ʻAʻole pono ʻoe e lawe i ʻelua mau aniani me ʻoe, a ʻaʻole pono ʻoe e hoʻololi pinepine ma waena o nā aniani mamao a kokoke.

Nā hemahema o nā bifocals: ʻOi aku ka liʻiliʻi o ke kahua o ka ʻike ma mua o nā aniani ʻike hoʻokahi, ʻoi aku ka ʻike kokoke. No ka laʻana, pono e hana pū ka heluhelu ʻana i nā puke a me nā nūpepa me nā neʻe ʻana o ke poʻo. Aia nā hemahema o ka lele ʻana a me ka neʻe ʻana o ke kiʻi, a aia kahi laina hoʻokaʻawale, kahi maʻalahi ke ʻike ʻia ke komo ʻana. E hōʻike i ka makahiki me nā bifocals.
