Leni Bifocal
Pehea e haʻi ai inā makemake ʻoe i nā Bifocals
ʻO ka Presbyopia kahi maʻi e pili ana i ka makahiki e hopena i ka pohō kokoke i ka ʻike.ʻIke pinepine ia me ka mālie;e paʻakikī ana ʻoe e ʻike i kahi puke a i ʻole nūpepa ma kahi kokoke a e neʻe maoli i kahi mamao aku mai kou alo aku i ʻike maopopo ʻia.
Ma kahi o ke 40 o kona mau makahiki, ua nalowale ka lens crystalline i loko o ka maka.I ka wā ʻōpiopio, palupalu a maʻalahi kēia lens, hiki ke hoʻololi maʻalahi i ke ʻano i hiki ke hoʻohuli i ka mālamalama i ka retina.Ma hope o ke 40 makahiki, ʻoi aku ka paʻakikī o ka lens, a ʻaʻole hiki ke hoʻololi maʻalahi i ke ʻano.ʻOi aku ka paʻakikī o ka heluhelu ʻana a i ʻole ka hana ʻana i nā hana kokoke.
Nā Lens Bifocal
Loaʻa i nā lens maka aniani Bifocal nā mana lens ʻelua e kōkua iā ʻoe e ʻike i nā mea ma nā mamao a pau ma hope o kou nalowale ʻana i ka hiki ke hoʻololi maoli i ka nānā ʻana o kou mau maka ma muli o ka makahiki, i kapa ʻia ʻo presbyopia.Ma muli o kēia hana kikoʻī, ʻōlelo pinepine ʻia nā lens bifocal i nā poʻe ma luna o 40 mau makahiki e kōkua i ka hoʻopaʻi ʻana i ka hōʻino kūlohelohe o ka ʻike ma muli o ke kaʻina hana ʻelemakule.
ʻEkolu Manaʻo o nā Lens Bifocal
ʻOiai ke kumu e pono ai ʻoe i kahi ʻōlelo kuhikuhi no ka hoʻoponopono ʻana i ka ʻike kokoke, hana like nā bifocals āpau.Aia ma kahi ʻāpana liʻiliʻi ma ka ʻaoʻao haʻahaʻa o ka lens ka mana e pono ai e hoʻoponopono i kāu ʻike kokoke.ʻO ke koena o ka lens no kāu ʻike mamao.ʻO ka māhele lens i hoʻolaʻa ʻia no ka hoʻoponopono ʻana i ka ʻike kokoke hiki ke ʻekolu ʻano:
ʻAno 1
Manaʻo ʻia ka Flat Top ʻo ia kekahi o nā lens multifocal maʻalahi loa e hoʻololi ai, no laila ʻo ia ka bifocal maʻamau i hoʻohana ʻia (FT 28mm i kapa ʻia ʻo ka nui maʻamau).ʻO kēia ʻano lens kekahi o nā mea maʻalahi loa i loaʻa i nā ʻano mea like ʻole a me nā lens hōʻoluʻolu.Hoʻohana ka Flat Top i ka laulā piha o ka māhele e hāʻawi ana i ka mea hoʻohana i kahi heluhelu a me ka hoʻololi mamao.
Kinohi 2
E like me ka hōʻike ʻana o ka inoa, he poepoe ka bifocal poepoe ma lalo.Ua hoʻolālā mua ʻia lākou e kōkua i ka poʻe ʻaʻahu e hele maʻalahi i ka wahi heluhelu.Eia naʻe, hoʻemi kēia i ka laulā o ka ʻike kokoke i loaʻa ma luna o ka māhele.Ma muli o kēia, ʻoi aku ka maikaʻi o nā bifocals poepoe ma mua o nā bifocals flat-top. ʻO ka māhele heluhelu ka mea maʻamau i loaʻa ma 28mm.
