ʻAʻohe hopohopo - ʻaʻole ia he manaʻo e pono ʻoe e komo i nā bifocals a i ʻole trifocals maikaʻi ʻole. No ka hapa nui o ka poʻe, ʻoi aku ka maikaʻi o nā aniani holomua line-free.
He aha nā aniani holomua?
ʻO nā aniani holomua he mau aniani maka multifocal ʻaʻohe laina e like me nā aniani ʻike hoʻokahi. I nā huaʻōlelo ʻē aʻe, e kōkua nā aniani holomua iā ʻoe e ʻike maopopo i nā mamao āpau me ka ʻole o kēlā mau "laina bifocal" hoʻonāukiuki (a me ka wehewehe ʻana i ka makahiki) i ʻike ʻia ma nā bifocals maʻamau a me nā trifocals.
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.
ʻO nā bifocals, ma ka ʻaoʻao ʻē aʻe, ʻelua wale nō mana o ka lens - hoʻokahi no ka ʻike maopopo ʻana i nā mea mamao a ʻo ka lua o ka mana ma ka hapalua haʻahaʻa o ka lens no ka ʻike maopopo ʻana ma kahi mamao heluhelu i kuhikuhi ʻia. Ua wehewehe ʻia ka hui ʻana ma waena o kēia mau wahi mana like ʻole e kahi "laina bifocal" i ʻike ʻia e ʻoki ana ma waenakonu o ka lens.
ʻO nā aniani holomua, i kekahi manawa ua kapa ʻia ʻo "no-line bifocals" no ka mea ʻaʻohe o lākou laina bifocal ʻike ʻia. Akā, ʻoi aku ka holomua o ka hoʻolālā multifocal o nā aniani holomua ma mua o nā bifocals a i ʻole trifocals.
ʻO nā aniani holomua Premium, hāʻawi pinepine i ka ʻoluʻolu a me ka hana maikaʻi loa, akā he nui nā lama ʻē aʻe a me nā hana hou aʻe, e like me ka aniani holomua photochromic, ka aniani holomua bluecut a pēlā aku, a me nā mea like ʻole. Hiki iā ʻoe ke loaʻa i kahi kūpono nou iho ma kā mākou ʻaoʻaohttps://www.universeoptical.com/progressive-lenses-product/.
Hoʻomaka ka hapa nui o ka poʻe e pono i nā aniani maka multifocal i kekahi manawa ma hope o 40 mau makahiki. ʻO kēia ka manawa e hōʻemi ai kahi loli maʻamau o ka ʻelemakule i ka maka i kapa ʻia ʻo presbyopia i ko mākou hiki ke ʻike maopopo i kahi kokoke. No kekahi me ka presbyopia, loaʻa i nā aniani holomua nā pono ʻike maka a me nā mea hoʻonaninani i hoʻohālikelike ʻia me nā bifocals a me nā trifocals kuʻuna.
Hāʻawi ka hoʻolālā multifocal o nā aniani holomua i kēia mau pono koʻikoʻi:
Hāʻawi ia i ka ʻike maopopo ma nā mamao āpau (ma mua o ʻelua a ʻekolu paha mau mamao nānā like ʻole).
Hoʻopau ia i ka "lele kiʻi" hoʻonāukiuki i hoʻokumu ʻia e nā bifocals a me nā trifocals. ʻO kēia kahi e loli koke ai nā mea i ke ʻano maopopo a me ke kūlana i ʻike ʻia ke neʻe kou mau maka ma waena o nā laina i ʻike ʻia i loko o kēia mau aniani.
No ka mea, ʻaʻohe "laina bifocal" i ʻike ʻia i loko o nā aniani holomua, hāʻawi lākou iā ʻoe i kahi ʻano ʻōpio ma mua o nā bifocals a i ʻole trifocals. (ʻO kēia kumu wale nō paha ke kumu e ʻoi aku ai ka nui o ka poʻe i kēia lā e hoʻohana ana i nā aniani holomua ma mua o ka poʻe e hoʻohana ana i ka bifocal a me nā trifocals i hui pū ʻia.)
