Nā hiʻohiʻona: Heʻelua mau wahi pāʻaniʻelua ma luna o kahi lens,ʻo ia nō, nā leʻa liʻiliʻi me nā mana liʻiliʻi ma luna o kahi lens maʻamau;
Hoʻohanaʻia no nā maʻi me ka presbyopia eʻike i kahi mamao a kokoke i ka lōʻihi;
ʻO ka luna o ka luminosity i ka wā e nānā ai i kahi mamao (i kekahi manawa pōkole), aʻo ka haʻahaʻa haʻahaʻa ka kukui i ka wā e heluhelu ai;
Ua kapaʻia ka pae'āina mamao i ka mana o luna a kokoke i ke kūlana haʻahaʻa haʻahaʻa, a ua kapaʻia kaʻokoʻa ma waena o ka mana o luna a me ka mana haʻahaʻa).
Wahi a keʻano o ka'āpana liʻiliʻi, hiki iā ia ke hoʻokaʻawaleʻia i loko o ka buifcal blat-top-top-top-top bifocal a pēlā aku.

No ka mea,ʻo ka but but brifocal kekahi o nā multifal i maʻalahi loa e hoʻoponopono ai,ʻo ia kekahi o nā mea nui o nā biforal nui loa i ka honua. He wahi'ē aʻe "lele" mai ka mamao a kokoke i kaʻike kokoke i nā mea nāwaliwaliʻelua i nā aniani i hoʻohanaʻia ma ka lima. Ke maopopo nei ka laina no ka mea ke hoʻololi koke nei ka loli i nā mana me ka maikaʻiʻole e hāʻawi iāʻoe i kahi o ka heluhelu heluheluʻana ma kahi o ka lōʻihi o ka heluheluʻana i nā lens. He mea maʻalahi nō hoʻi e aʻo i kekahi i keʻano e hoʻohana ai i ka bifocal i loko o ia mea e hoʻohana wale ana i ka piko a me lalo no ka heluheluʻana.
