1）He aha nā lens bifocal?
ʻO Bifocals nā lens me ʻelua mana hoʻoponopono ʻokoʻa.Hoʻomaopopo pinepine ʻia nā bifocals i nā presbyopes
e koi ana i ka hoʻoponopono ʻana no ka myopia (nearsightedness) a i ʻole hyperopia (farsightedness) me ka ʻole o ka hoʻoponopono ʻana no ka astigmatism (ka hihiʻo ʻino ma muli o ke ʻano like ʻole o ka lens a i ʻole ka cornea).ʻO ke kumu nui o ka lens bifocal ʻo ia ka hāʻawi ʻana i ke kaulike kūpono ma waena o ka mamao a me ka ʻike kokoke.
ʻO ka mea maʻamau, nānā ʻoe i luna a ma o ka ʻāpana mamao o ka lens ke nānā aku ʻoe i nā wahi mamao aku, a ʻo ʻoe
E nānā i lalo a ma o ka ʻāpana bifocal o ka lens ke nānā aku i ka heluhelu ʻana i nā mea a i ʻole nā mea i loko o 18
ʻīniha o kou mau maka. Ua ʻae ʻia ʻo Benjamin Franklin i haku i ka bifocal.ʻO ka bifocal maʻamau i kēia mau lā ʻo ka Straight Top 28 Bifocal nona kahi laina pololei ma luna o luna me kahi radius 28mm.Nui nā ʻano like ʻole o nā bifocal luna pololei i loaʻa i kēia lā me: Straight Top 25, Straight Top 35, Straight Top 45 a me ka Executive (The Original Franklin Seg) e holo ana i ka laulā piha o ka lens.
Ma waho aʻe o nā bifocal luna pololei, aia nā bifocal poʻe holoʻokoʻa me ka Round 22, Round 24, Round 25.
a me ka Hui Hoʻohui 28 (ʻaʻohe ʻāpana kikoʻī).
ʻO ka pōmaikaʻi o ka ʻāpana poepoe ʻo ia ka liʻiliʻi o ka lele ʻana o ke kiʻi e like me ka hoʻololi ʻana mai kahi mamao a i kahi kokoke o ka lens.
2）Nā hiʻohiʻona o nā lens photochromic
Loaʻa nā lens Photochromic ma kahi kokoke i nā mea lens a me nā hoʻolālā, me nā kuhikuhi kiʻekiʻe, bifocal a me ka holomua.ʻO kahi pōmaikaʻi hou o nā lens photochromic ʻo ia ka pale ʻana i kou mau maka mai ka 100 pākēneka o nā kukuna UVA a me UVB ʻino o ka lā.
Ma muli o ka pili ʻana o ka ʻike ʻana o ke kanaka i ka lā a me ka radiation UV i ka maʻi ma hope o ke ola, he mea maikaʻi e noʻonoʻo i nā lens photochromic no nā maka maka o nā keiki a me nā maka aniani no nā pākeke.
