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)He aha ka lens photochromic?
Ua ʻike ʻia nā lens Photochromic he "photosensitive lenses".E like me ke kumu o ka hoʻohuli ʻana o ke kala ʻulaʻula alternation, hiki i ka lens ke pōʻeleʻele ma lalo o ka mālamalama a me ka radiation ultraviolet, pale i ke kukui ikaika a hoʻopaʻa i ke kukui ultraviolet, a hōʻike i ka absorption kū ʻole i ka mālamalama ʻike.Hoʻi i ka pōʻeleʻele, hiki ke hoʻihoʻi koke i ke ʻano o ka ʻulaʻula ʻole, e hōʻoia i ka transmittance lens.No laila, kūpono ka lens hoʻololi kala no ka hoʻohana ʻana i loko a me waho i ka manawa like, e pale aku i ka lā, nā kukui ultraviolet, ka ʻālohilohi o ka maka.E like me ke kumu o ka hoʻohuli ʻana o ke kala ʻulaʻula alternation, hiki i ka lens ke pōʻeleʻele ma lalo o ka mālamalama a me ka radiation ultraviolet, pale i ke kukui ikaika a hoʻopaʻa i ke kukui ultraviolet, a hōʻike i ka absorption kū ʻole i ka mālamalama ʻike.Hoʻi i ka pōʻeleʻele, hiki ke hoʻihoʻi koke i ke ʻano o ka ʻulaʻula ʻole, e hōʻoia i ka transmittance lens.No laila, kūpono ka lens hoʻololi kala no ka hoʻohana ʻana i loko a me waho i ka manawa like, e pale aku i ka lā, nā kukui ultraviolet, nā aniani i ka pōʻino o ka maka.
3) He aha ka ʻokoʻa ma waena o HC, HMC a me SHC?
Paʻa paʻa | ʻO ka uhi AR/Ka uhi nui paʻakikī | Ka uhi ʻana o ka super hydrophobic |
paʻakikī ka lens uncoated a hoʻonui i ka pale abrasion | hoʻonui i ka transmittance o ka lens a hōʻemi i ka noʻonoʻo ʻana o ka ʻili | hana i ka lens i wai ʻole, antistatic, anti slip a me ka ʻaila |
