Akā ma waho aʻe o ka lilo ʻana i lens multifocal me ka ʻike ʻole ʻia o nā laina, hiki i nā lens progressive ke hiki i nā poʻe me ka presbyopia ke ʻike maopopo hou i nā mamao āpau.
Nā pōmaikaʻi o nā aniani holomua ma mua o nā bifocals
ʻElua wale nō mana o nā aniani maka bifocal: hoʻokahi no ka ʻike ʻana ma waena o ka lumi a ʻo kekahi no ka ʻike kokoke. ʻO nā mea ma waena, e like me ka pale kamepiula a i ʻole nā mea ma ka papa o ka hale kūʻai meaʻai, pinepine lākou e noho pōwehiwehi me nā bifocals.
I mea e ʻike maopopo ai i nā mea ma kēia pae "waena", pono nā mea e hoʻohana ana i ka bifocal e hoʻoluliluli i ko lākou mau poʻo i luna a i lalo, e nānā ana ma waena o luna a laila ma lalo o kā lākou bifocals, e hoʻoholo ai i ka ʻāpana o ka lens e hana maikaʻi ana.
Hoʻohālikelike pono nā aniani holomua i ka ʻike kūlohelohe āu i hauʻoli ai ma mua o ka hoʻomaka ʻana o ka presbyopia. Ma kahi o ka hāʻawi ʻana i ʻelua mau mana aniani e like me nā bifocals (a i ʻole ʻekolu, e like me nā trifocals), ʻo nā aniani holomua he mau aniani "multifocal" maoli e hāʻawi ana i kahi holomua maʻalahi a maʻalahi o nā mana aniani he nui no ka ʻike maopopo ma loko o ka lumi, kokoke a ma nā mamao āpau ma waena.
ʻIke kūlohelohe me ka ʻole o ka "lele kiʻi"
ʻO nā laina i ʻike ʻia ma nā bifocals a me nā trifocals he mau wahi kahi i loaʻa ai kahi ʻano koke. Eia kekahi, ma muli o ka palena o ka helu o nā mana lens ma nā bifocals a me nā trifocals, ua kaupalena ʻia kou hohonu o ka nānā ʻana me kēia mau aniani. I mea e ʻike maopopo ʻia ai, pono nā mea i loko o kahi laulā kikoʻī o nā mamao. ʻO nā mea ma waho o nā mamao i uhi ʻia e nā mana lens bifocal a i ʻole trifocal e palalulu ʻia a loli ka mana lens.
ʻO nā aniani holomua, ma ka ʻaoʻao ʻē aʻe, he holomua mālie a maʻalahi hoʻi o nā mana aniani no ka ʻike maopopo ma nā mamao āpau. Hāʻawi nā aniani holomua i kahi hohonu kūlohelohe o ka nānā ʻana me ka ʻole o ka "lele kiʻi."
Hoʻololi mālie ka mana o nā aniani holomua mai kekahi wahi a i kekahi ma luna o ka ʻili o ka aniani, e hāʻawi ana i ka mana aniani kūpono no ka ʻike maopopo ʻana i nā mea ma kahi mamao loa.
Hāʻawi ia i ka ʻike maopopo ma nā mamao āpau (ma mua o ʻelua a ʻekolu paha mau mamao nānā like ʻole).
No ka ʻike maikaʻi loa, ka ʻoluʻolu a me ke ʻano, hiki iā ʻoe ke koho i nā alaloa ākea no ka maʻalahi a me ka wikiwiki o ka hoʻololi ʻana ma mua o ka lens holomua o ka hanauna hope loa. Hiki iā ʻoe ke neʻe i loko o ka ʻaoʻaohttps://www.universeoptical.com/wideview-product/e nānā i nā kikoʻī hou aku e pili ana i kā mākou hoʻolālā holomua hou loa.
