Nā hiʻohiʻona huahana
1. He aha nā ʻano o ka lens 1.74?
①Ke kūʻē i ka hopena: 1.74 mau lens index kiʻekiʻe e kū i ke kūlana FDA, hiki ke hele i ka hoʻāʻo spere hāʻule, ʻoi aku ke kūpaʻa kiʻekiʻe i nā ʻōpala a me ka hopena.
②Hoʻolālā: Hoʻokokoke ʻo ia i ka pihi kumu pālahalaha, hiki ke hāʻawi i ka poʻe i ka hōʻoluʻolu hiʻohiʻona kupaianaha a me ka hoʻopiʻi nani
③Ka pale ʻana o UV: 1.74 nā lens hihiʻo hoʻokahi he UV400 pale, ʻo ia hoʻi ka pale piha i nā kukuna UV, me UVA a me UVB, pale i kou mau maka i kēlā me kēia manawa a me nā wahi āpau.
UV400 Palekana 1.74 High Index Lenses, Uncoated Eyeglass Lens Blanks No ka Mana Kiʻekiʻe
④Kūlou nā lens kuhikuhi kiʻekiʻe i ke kukui ma kahi kihi ʻoi aku ka liʻiliʻi ma mua o nā mana kuhikuhi liʻiliʻi.
ʻO ka 'index' ka hopena i hāʻawi ʻia ma ke ʻano he helu: 1.56,1.61,1.67 a i ʻole 1.74 a ʻoi aku ka kiʻekiʻe o ka helu, ʻoi aku ka nui o ka mālamalama a i ʻole 'hoʻolohi'.No laila, liʻiliʻi ka curvature o kēia mau lens no ka mana hoʻokahi e koi ana i ka waiwai/mea waiwai.
⑤ ʻO ke ʻano Aspherical: ʻOi aku ka lahilahi a ʻoi aku ka māmā o nā lens Aspherical ma mua o nā lens spherical, e hoʻomaha maikaʻi i ka luhi ʻike ma muli o ka hoʻokaumaha.Eia kekahi, hiki iā lākou ke hōʻemi i ka aberration a me ka distortion, e hāʻawi i ka poʻe i ʻoi aku ka ʻoluʻolu o ka ʻike.
⑥Super Hydrophobic Coating: Ua kapa ʻia ʻo ia ka crazil coating, hiki ke hana i ka ʻili o nā lens super hydrophobic, smudge resistance, anti static, anti scratch, reflection and oil, etc.
2.He aha nā ʻenehana kukui anti-blue nui?
① ʻenehana noʻonoʻo papa kiʻiʻoniʻoni: ma o ka uhi ʻana o ka lens e hōʻike i ke kukui polū, i hiki ai ke hoʻokō i ka hopena pale kukui polū.
②ʻenehana hoʻoheheʻe substrate: ma o nā mea ʻoki kukui polū i hoʻohui ʻia i loko o ka monomer o ka lens a me ka absorption kukui polū i mea e loaʻa ai ka hopena pale kukui polū.
③film layer reflection + substrate absorption: ʻo kēia ka ʻenehana anti-blue light hou loa e hoʻohui i nā pono o nā ʻenehana ʻelua ma luna a me ka pale ʻana i ka hopena.
3. Kākoʻo koho?
E like me ka 1.74 kiʻekiʻe index lens, super hydrophobic coating ʻo ia wale nō ke koho uhi no ia.
ʻO ka super hydrophobic coating ka inoa ʻo crazil coating, hiki ke hana i nā lens i wai ʻole, antistatic, anti slip a me ka pale ʻaila.
Ma ka ʻōlelo maʻamau, hiki i ka uhi super hydrophobic ke noho 6 ~ 12 mau mahina.
