ʻAʻohe hopohopo - ʻaʻole ia he manaʻo ʻoe e ʻaʻahu i nā bifocal maikaʻi ʻole a i ʻole trifocals. No ka hapanui o ka poʻe, ʻoi aku ka maikaʻi o nā lens progressive line-free.
He aha nā lens holomua?
ʻO nā lens holomua he mau lens eyeglass multifocal laina ʻole e nānā like me nā lens hihiʻo hoʻokahi. Ma nā huaʻōlelo ʻē aʻe, e kōkua nā lens holomua iā ʻoe e ʻike maopopo i nā mamao āpau me ka ʻole o kēlā mau "laina bifocal" hoʻonāukiuki (a me ka wehewehe makahiki) i ʻike ʻia i nā bifocal maʻamau a me nā trifocals.
Hoʻololi liʻiliʻi ka mana o nā lens holomua mai kahi a kahi kiko ma ka ʻili o ka lens, e hāʻawi ana i ka mana leki kūpono no ka ʻike pono ʻana i nā mea ma kahi mamao.
ʻO ka Bifocals, ma kekahi ʻaoʻao, ʻelua wale nō mana lens - hoʻokahi no ka ʻike maopopo ʻana i nā mea mamao a me ka lua o ka mana ma ka hapa 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 ʻāpana mana ʻokoʻa e kahi "laina bifocal" ʻike ʻia e ʻoki ana i ke kikowaena o ka lens.
ʻO nā lens 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 maikaʻi o ka hoʻolālā multifocal holomua ma mua o nā bifocals a i ʻole trifocals.
ʻO nā lens progressive premium, hāʻawi maʻamau i ka hōʻoluʻolu a me ka hana maikaʻi loa, akā nui nā mana ʻē aʻe a me nā hana ʻē aʻe pū kekahi, e like me photochromic progressive lens, bluecut progressive lens a pēlā aku, a me nā mea like ʻole. Hiki iā ʻoe ke loaʻa kahi mea kūpono iā ʻoe iho ma kā mākou ʻaoʻaohttps://www.universeoptical.com/progressive-lenses-product/.
Hoʻomaka ka hapa nui o ka poʻe e makemake i nā maka aniani multifocal i kekahi manawa ma hope o ka makahiki 40. ʻO kēia ka manawa e hoʻololi ai ka ʻelemakule maʻamau i ka maka i kapa ʻia ʻo presbyopia e hōʻemi i ko mākou hiki ke ʻike maopopo ma kahi kokoke. No kēlā me kēia me ka presbyopia, loaʻa i nā lens holomua nā pōmaikaʻi ʻike a me nā mea hoʻonaninani i hoʻohālikelike ʻia me nā bifocals kahiko a me nā trifocals.
Hāʻawi ka hoʻolālā multifocal o nā lens holomua ma lalo o nā pono nui:
Hāʻawi ia i ka ʻike maopopo ma nā mamao āpau (ma mua o ʻelua a ʻekolu paha mau mamao ʻike ʻokoʻa).
Hoʻopau ia i ka "lele kiʻi" pilikia i hana ʻia e nā bifocals a me nā trifocals. ʻO kēia kahi e hoʻololi koke ai nā mea i ka mālamalama a me ke kūlana i ka wā e neʻe ai kou mau maka i nā laina ʻike ʻia i kēia mau lens.
No ka mea ʻaʻohe "laina bifocal" i ʻike ʻia i nā lens holomua, hāʻawi lākou iā ʻoe i kahi hiʻohiʻona ʻōpio ma mua o nā bifocals a i ʻole trifocals. (ʻO kēia wale nō ke kumu e hoʻohana ai ka poʻe i kēia lā i nā leki holomua ma mua o ka helu i hui pū ʻia nā bifocal a me nā trifocals.)
